The marked release of catecholamines during subarachnoid hemorrhage is an important aspect of the pathobiology following aneurysmal rupture. This narrative review aims to identify how catecholamines influence aneurysmal subarachnoid hemorrhage (aSAH) outcomes. aSAH is a critical neurological condition characterized by hemorrhage into the subarachnoid space, leading to severe neurological deficits and mortality. Catecholamines, including epinephrine, norepinephrine, and dopamine, are the body's stress responses, which can lead to secondary injuries following aSAH. This review was conducted through a targeted literature search of relevant studies examining the relationship between aSAH, catecholamines, and clinical outcomes. Searches were performed in PubMed, Scopus, The Cochrane Library, Medline (Ovid), Embase (Ovid), and CINAHL, including publications up to July 2024. Search terms combined keywords and subject headings related to “subarachnoid hemorrhage” or “aSAH,” “catecholamines,” “epinephrine,” “norepinephrine,” “dopamine,” and outcome-related terms such as “prognosis,” “mortality,” and “neurological outcome.” Articles were selected based on relevance, and key findings were synthesized descriptively to provide a comprehensive overview of current knowledge in this area. Elevated levels of catecholamines are observed following aSAH and are associated with increased sympathetic nervous system activity. This catecholamine surge contributes to pathological processes, including vasospasm, blood-brain barrier disruption, cerebral edema, and neuronal damage. The review highlights the implications of catecholamine levels; where higher concentrations correlate with poorer outcomes and higher mortality rates. Understanding the mechanisms responsible for secondary injury due to catecholamines surge following aSAH shall facilitate the development of therapeutic approaches to prevent secondary brain injury and improve outcomes.

Abstract PDF Supplementary Material: Background
Arterial pH reflects both metabolic and respiratory distress in cardiac arrest and has prognostic implications. However, it was excluded from the 2024 update of the Utstein out-of-hospital cardiac arrest (OHCA) registry template. We investigated the rationale for including arterial pH into models predicting clinical outcomes. Methods: Data were sourced from the Korean Cardiac Arrest Research Consortium, a nationwide OHCA registry (NCT03222999). Prediction models were constructed using logistic regression, random forest, and eXtreme Gradient Boosting frameworks. Each framework included three model types: pH, low-flow time, and combined models. Then the area under the receiver operating characteristic curve (AUROC) of each predicting model was compared. The primary outcome was 30- day death or neurologically unfavorable status (cerebral performance category ≥3). Results: Among the 15,765 patients analyzed, 92.2% experienced death or unfavorable neurological outcomes. The predicting performance of the models including pH (AUROC, 0.92–0.94) were comparable to the models including low-flow time in all frameworks (0.93–0.94) (all P>0.05). Inclusion of pH into low-flow time models consistently showed higher AUROCs than individual models in all frameworks (AUROC, 0.93–0.95; all P<0.05). Conclusions: The predicting performance of models including arterial pH was comparable to models including low-flow time, and addition of arterial pH into low-flow time models could increase the performance of the models.

Abstract PDF

Blood gas analysis is an essential diagnostic tool used for assessing acid-base balance, ventilation, and oxygenation in critically ill patients. Arterial blood gas analysis (ABGA) remains the gold standard, primarily due to its accuracy in measuring oxygenation. Venous blood gas analysis (VBGA), in contrast, serves as a less invasive alternative and is particularly useful for evaluating acid-base status and metabolic function. Important parameters such as oxygen saturation of central venous blood (ScvO₂) and venous-to-arterial carbon dioxide pressure difference (∆pv-aCO₂) provide critical insights into hemodynamic status, cardiac output, and tissue perfusion. Although VBGA cannot replace ABGA for the precise assessment of oxygenation, it remains a valuable tool in clinical scenarios involving hemodynamic monitoring, shock management, and critical care decision-making.

Background
Inflammation is involved in the pathophysiology of postoperative acute kidney injury (AKI). We investigated whether preoperative platelet-to-white blood cell ratio (PWR), a novel serum biomarker of systemic inflammation, was associated with postoperative AKI following cerebral aneurysm treatment. We also compared the discrimination power of preoperative PWR with those of other preoperative systemic inflammatory indices in predicting postoperative AKI.
Methods
Perioperative data including preoperative systemic inflammatory indices and cerebral aneurysm-related variables were retrospectively analyzed in 4,429 cerebral aneurysm patients undergoing surgical clipping or endovascular coiling. Based on the cutoff value of preoperative PWR, patients were divided into the high PWR (≥39.04, n=1,924) and low PWR (<39.04, n=2,505) groups. After propensity score matching (PSM), 1,168 patients in each group were included in the data analysis. AKI was defined according to the Kidney Disease Improving Global Outcomes guidelines.
Results
Postoperative AKI occurred more frequently in the low PWR group than in the high PWR group before PSM (45 [1.8%] vs. 7 [0.4%], P<0.001) and after (17 [1.5%] vs. 5 [0.4%], P=0.016). A low preoperative PWR was predictive of postoperative AKI before PSM (odds ratio [95% CI], 3.93 [1.74–8.87]; P<0.001) and after (3.44 [1.26–9.34], P=0.016). Preoperative PWR showed the highest area under the curve for postoperative AKI (0.713 [0.644–0.782], P<0.001), followed by preoperative platelet-to-neutrophil ratio (0.694 [0.619–0.769], P<0.001), neutrophil percentage-to-albumin ratio (0.671 [0.592–0.750], P<0.001), white blood cell-to-hemoglobin ratio (0.665 [0.579–0.750], P<0.001), neutrophil-to-lymphocyte ratio (0.648 [0.569–0.728], P<0.001), and systemic inflammatory index (0.615 [0.532–0.698], P=0.004).
Conclusions
A low preoperative PWR was associated with postoperative AKI following cerebral aneurysm treatment.

Abstract PDF: Background
Sepsis is a life-threatening condition that affects the cardiovascular and renal systems. Severe hypotension during sepsis compromises tissue perfusion, which can lead to multiple organ dysfunction and death. Phosphodiesterase 5 (PDE5) degrades intracellular cyclic guanosine monophosphate (cGMP) levels which promotes vasodilatation in specific sites. Our previous studies show that inhibiting cGMP production in early sepsis increases mortality, implying a protective role for cGMP production. Then, we hypothesized that cGMP increased by tadalafil (PDE5 inhibitor) could improve microcirculation and prevent sepsis-induced organ dysfunction.
Methods
Rats were submitted to cecal ligation and puncture (CLP) sepsis model and treated with tadalafil (2 mg/kg, s.c.) 8 hours after the procedure. Hemodynamic, inflammatory and biochemical assessments were performed 24 hours after sepsis induction. Moreover, the effect of tadalafil on the survival of septic rats was evaluated for 5 days.
Results
Tadalafil treatment improves basal renal blood flow during sepsis and preserves it during noradrenaline infusion. Sepsis induces hypotension, impaired response to noradrenaline, and increased cardiac and renal neutrophil infiltration, in addition to increased levels of plasma nitric oxide and lactate. None of these dysfunctions were changed by tadalafil. Additionally, tadalafil treatment did not increase the survival rate of septic rats.
Conclusions
Tadalafil improved microcirculation of septic animals; however, no beneficial effects were observed on macrocirculation and inflammation parameters. Then, the potential benefit of tadalafil in the prognosis of sepsis should be evaluated within a therapeutic strategy covering all sepsis injury mechanisms.

Abstract PDF: Background
Despite the high mortality associated with bloodstream infection (BSI), early detection of this condition is challenging in critical settings. The objective of this study was to create a machine learning tool for rapid recognition of BSI in critically ill children.
Methods
Data were extracted from a derivative cohort comprising patients who underwent at least one blood culture during hospitalization in the pediatric intensive care unit (PICU) of a tertiary hospital from January 2020 to June 2023 for model development. Data from another tertiary hospital were utilized for external validation. Variables selected for model development were age, white blood cell count with segmented neutrophil count, C-reactive protein, bilirubin, liver enzymes, glucose, body temperature, heart rate, and respiratory rate. Algorithms compared were extra trees, random forest, light gradient boosting, extreme gradient boosting, and CatBoost.
Results
We gathered 1,806 measurements and recorded 290 hospitalizations from 263 patients in the derivative cohort. Median age on admission was 43 months, with an interquartile range of 10–118.75 months, and a male predominance was observed (n=160, 55.2%). Candida albicans was the most prevalent pathogen, and median duration to confirm BSI was 3 days (range, 3–4). Patients with BSI experienced significantly higher in-hospital mortality and prolonged stays in the PICU than patients without BSI. Random forest classifier achieved the highest area under the receiver operating characteristic curve of 0.874 (0.762 for the validation set).
Conclusions
We developed a machine learning model that predicts BSI with acceptable performance. Further research is necessary to validate its effectiveness.

Abstract PDF

Background
Red blood cells (RBCs) are a limited resource, and the adverse effects of transfusion must be considered. Multiple randomized controlled trials on transfusion thresholds have been conducted, leading to the establishment of a restrictive transfusion strategy. This study aimed to investigate the status of RBC transfusions in critically ill patients.
Methods
This cohort study was conducted at five university hospitals in South Korea. From December 18, 2022, to November 30, 2023, 307 nontraumatic, anemic patients admitted to intensive care units through the emergency departments were enrolled. We determined whether patients received RBC transfusion, transfusion triggers, and the clinical results.
Results
Of the 154 patients who received RBC transfusions, 71 (46.1%) had a hemoglobin level of 7 or higher. Triggers other than hemoglobin level included increased lactate levels in 75 patients (48.7%), tachycardia in 47 patients (30.5%), and hypotension in 46 patients (29.9%). The 28-day mortality rate was not significantly reduced in the group that received transfusions compared to the non-transfusion group (21.4% vs. 26.8%, P=0.288). There was no difference in the intensive care unit and hospital length of stay or the proportion of survival to discharge between the two groups. The prognosis showed the same pattern in various subgroups.
Conclusions
Despite the large number of RBC transfusions used in contradiction to the restrictive strategy, there was no notable difference in the prognosis of critically ill patients. To minimize unnecessary RBC transfusions, the promotion of transfusion guidelines and research on transfusion criteria that reflect individual patient conditions are required.

Abstract PDF

Background
Platelet-to-Lymphocyte ratio (PLR) has been studied as a prognostic factor for various diseases and traumas. This study examined the utility of PLR as a tool for predicting 30-day mortality in patients experiencing severe trauma.
Methods
This study included 139 patients who experienced trauma and fulfilled ≥1 criteria for activation of the hospital’s severe trauma team. Patients were divided into non-survivor and survivor groups. Mean PLR values were compared between the groups, the optimal PLR cut-off value was determined, and mortality and survival analyses were performed. Statistical analyses were performed using SPSS ver. 26.0. The threshold of statistical significance was P<0.05.
Results
There was a significant difference in mean (±standard deviation) PLR between the non-survivor (n=36) and survivor (n=103) groups (53.4±30.1 vs. 89.9±53.3, respectively; P<0.001). Receiver operating characteristic (ROC) curve analysis revealed an optimal PLR cut-off of 65.35 (sensitivity, 0.621; specificity, 0.694, respectively; area under the ROC curve, 0.742), and Kaplan-Meier survival analysis revealed a significant difference in mortality rate between the two groups.
Conclusions
PLR can be calculated quickly and easily from a routine complete blood count, which is often performed in the emergency department for individuals who experience trauma. The PLR is useful for predicting 30-day mortality in trauma patients with severe trauma team activation.

Abstract PDF: Background
Extracorporeal blood-purification techniques are frequently needed in the pediatric intensive care unit (PICU), yet data on their clinical application are lacking. This study aims to review the indications, rate of application, clinical characteristics, complications, and outcomes of patients undergoing extracorporeal blood purification (i.e., by continuous renal replacement therapy [CRRT] or therapeutic plasma exchange [TPE]) in our PICU, including before the coronavirus disease 2019 (COVID-19) pandemic in 2019 and during the pandemic from 2020 to 2022.
Methods
This study included children admitted for extracorporeal blood-purification therapy in the PICU. The indications for TPE were analyzed and compared to the American Society for Apheresis categories.
Results
In 82 children, 380 TPE sessions and 37 CRRT sessions were carried out children, with 65 patients (79%) receiving TPE, 17 (20.7%) receiving CRRT, and four (4.8%) receiving both therapies. The most common indications for TPE were neurological diseases (39/82, 47.5%), followed by hematological diseases (18/82, 21.9%). CRRT was mainly performed for patients suffering from acute kidney injury. Patients with neurological diseases received the greatest number of TPE sessions (295, 77.6%). Also, the year 2022 contained the greatest number of patients receiving extracorporeal blood-purification therapy (either CRRT or TPE).
Conclusions
The use of extracorporeal blood-purification techniques increased from 2019 through 2022 due to mainly autoimmune dysregulation among affected patients. TPE can be safely used in an experienced PICU. No serious adverse events were observed in the patients that received TPE, and overall survival over the 4 years was 86.5%.

Abstract PDF: Background
In the present study, arterial and venous blood was collected from patients who were candidates for elective coronary artery bypass grafting (CABG); the blood was stored for 28 days and cellular, biomechanical, and hematological changes in blood were compared to determine whether stored arterial blood is superior to stored venous blood.
Methods
The present follow-up comparative study included 60 patients >18 years of age, with hemoglobin >14 mg/dl and ejection fraction >40% who were candidates for CABG. After induction of anesthesia, 250 ml of arterial or venous blood was drawn from patients (arterial blood group and venous blood group). Laboratory blood samples were taken at specified times from the collected blood and re-injected into the patients after CABG.
Results
Significant differences were observed in pH, partial pressure of carbon dioxide (PCO2), partial pressure of oxygen (PO2), bicarbonate (HCO3), and glucose values at several time points between the groups. Other parameters such as urea and creatinine did not show any significant differences between the groups.
Conclusions
Twenty-eight days of storage can have a negative effect on some of the cellular, biochemical, and hematological components of arterial and venous blood; however, the quality of stored arterial blood and venous blood does not differ significantly.

Abstract PDF

Hemorrhagic shock is a main cause of death in severe trauma patients. Bleeding trauma patients have coagulopathy on admission, which may even be aggravated by incorrectly directed resuscitation. The damage control strategy is a very urgent and essential aspect of management considering the acute coagulopathy of trauma and the physiological status of bleeding trauma patients. This strategy has gained popularity over the past several years. Patients in extremis cannot withstand prolonged definitive surgical repair. Therefore, an abbreviated operation, referred to as damage control surgery (DCS), is needed. In addition to DCS, the likelihood of survival should be maximized for patients in extremis by providing appropriate critical care, including permissive hypotension, hemostatic resuscitation, minimization of crystalloid use, early use of tranexamic acid, and avoidance of hypothermia and hypocalcemia. This review presents an overview of the evolving strategy of damage control in bleeding trauma patients.

Abstract PDF

Background
Exsanguination is a major cause of death in severe trauma patients. The purpose of this study was to analyze the prognostic impact of the initial lactate level for massive transfusion (MT) in severe trauma. We divided patients according to subgroups of traumatic brain injury (TBI) and non-TBI.
Methods
This single-institution retrospective study was conducted on patients who were admitted to hospital for severe trauma between January 2016 and December 2017. TBI was defined by a head Abbreviated Injury Scale ≥3. Receiver operating characteristic analysis was used to analyze the prognostic impact of the lactate level. Multivariate analyses were performed to evaluate the relationship between the MT and lactate level. The primary outcome was MT.
Results
Of the 553 patients, MT was performed in 62 patients (11.2%). The area under the curve (AUC) for the lactate level for predicting MT was 0.779 (95% confidence interval [CI], 0.742 to 0.813). The AUCs for lactate level in the TBI and non-TBI patients were 0.690 (95% CI, 0.627 to 0.747) and 0.842 (95% CI, 0.796 to 0.881), respectively. In multivariate analyses, the lactate level was independently associated with the MT (odds ratio [OR], 1.179; 95% CI, 1.070 to 1.299). The lactate level was independently associated with MT in non-TBI patients (OR, 1.469; 95% CI, 1.262 to 1.710), but not in TBI patients.
Conclusions
The initial lactate level may be a possible prognostic factor for MT in severe trauma. In TBI patients, however, the initial lactate level was not suitable for predicting MT.

Abstract PDF

Background
Snakebite can cause various complications, including coagulopathy. The clinical features of snakebite-associated coagulopathy differ from those of disseminated intravascular coagulation (DIC) caused by other diseases and its treatment is controversial.
Methods
We retrospectively reviewed the medical records of patients hospitalized for snakebite between January 2006 and September 2018.
Results
A total of 226 patients were hospitalized due to snakebite. Their median hospital stay was 4.0 days (interquartile range, 2.0 to 7.0 days). Five patients arrived at hospital with shock and one patient died. Twenty-one patients had overt DIC according to the International Society of Thrombosis and Hemostasis scoring system. Two patients developed major bleeding complications. Initial lower cholesterol level at presentation was associated with the development of overt DIC. International normalization ratio (INR) exceeding the laboratory’s measurement limit was recorded as late as 4 to 5 days after the bite. Higher antivenom doses (≥18,000 units) and transfusion of fresh frozen plasma (FFP) or cryoprecipitate did not affect prolonged INR duration or hospital stay in the overt DIC patients without bleeding.
Conclusions
Initial lower cholesterol level may be a risk factor for overt DIC following snakebite. Although patients lack apparent symptoms, the risk of coagulopathy should be assessed for at least 4 to 5 days following snakebite. Higher antivenom doses and transfusion of FFP or cryoprecipitate may be unbeneficial for coagulopathic patients without bleeding.

Abstract PDF

Extracorporeal membrane oxygenation (ECMO) is frequently associated with bleeding and coagulopathy complications, which may lead to the need for transfusion of multiple blood products. However, blood transfusions are known to increase morbidity and mortality, as well as hospital cost, in critically ill patients. In current practice, patients on ECMO receive a transfusion, on average, of 1-5 packed red blood cells (RBCs)/day, with platelet transfusion accounting for the largest portion of transfusion volume. Generally, adult patients require more transfusions than neonates or children, and patients receiving venovenous ECMO for respiratory failure tend to need smaller transfusion volumes compared to those receiving venoarterial ECMO for cardiac failure. Observation studies have reported that a higher transfusion volume was associated with increased mortality. To date, the evidence for transfusion in patients undergoing ECMO is limited; most knowledge on transfusion strategies was extrapolated from studies in critically ill patients. However, current data support a restrictive blood transfusion strategy for ECMO patients, and a low transfusion trigger seems to be safe and reasonable.

Abstract PDF

Background:
We compared the clinical outcomes of cardiac valve surgery in adult Jehovah’s Witness patients refusing blood transfusion to those in non-Jehovah’s Witness patients without any transfusion limitations.
Methods
From 2005 to 2014, 25 Jehovah’s Witnesses (JW group) underwent cardiac valve surgery using a blood conservation strategy. Twenty-five matched control patients (non-JW group) were selected according to sex, age, operation date, and surgeon. Both groups were managed according to general guidelines of anticoagulation for valve surgery.
Results
The operative mortality rate was 4.0% in the JW group and 0% in the non-JW group (p = 1.000). There was no difference in postoperative major complications between the groups (p = 1.000). The overall survival rate at 5 and 10 years was 85.6% ± 7.9% and 85.6% ± 7.9% in the JW group, respectively, and 100.0% ± 0.0% and 66.7% ± 27.2% in the non-JW group (p = 0.313). The valve-related morbidity-free survival rates (p = 0.625) and late morbidity-free survival rates (p = 0.885) were not significantly different between the groups.
Conclusions
Using a perioperative strategy for blood conservation, cardiac valve surgery without transfusion had comparable clinical outcomes in adult patients. This blood conservation strategy could be broadly applied to major surgeries with careful perioperative care.

Abstract PDF

Cardiac arrest associated with hyperkalemia during red blood cell transfusion is a rare but fatal complication. Herein, we report a case of transfusion-associated cardiac arrest following the initiation of extracorporeal membrane oxygenation support in a 9-month old infant. Her serum potassium level was increased to 9.0 mEq/L, soon after the newly primed circuit with pre-stored red blood cell (RBC) was started and followed by sudden cardiac arrest. Eventually, circulation was restored and the potassium level decreased to 5.1 mEq/L after 5 min. Extracorporeal membrane oxygenation (ECMO) priming is a relatively massive transfusion into a pediatric patient. Thus, to prevent cardiac arrest during blood-primed ECMO in neonates and infants, freshly irradiated and washed RBCs should be used when priming the ECMO circuit, to minimize the potassium concentration. Also, physicians should be aware of all possible complications associated with transfusions during ECMO.

Abstract PDF: BACKGROUND
Selenium is an essential trace-element with antioxidant and immunological function. We studied the relationship between blood selenium concentrations, systemic inflammatory response syndrome (SIRS) and organ dysfunctions in critically ill children.
METHODS
This was a retrospective, observational study of the blood selenium concentrations of critically ill children at the time of a pediatric intensive care unit admission.
RESULTS
A total of 62 patients with a median age of 18 (5-180) months were included in this study. The mean of blood selenium concentration (microg/dl) was 8.49 +/- 2.42. The platelet count (r = -0.378) and PaCO2 (r = -0.403) showed negative correlations with blood selenium concentration, while PaO2/FiO2 (r = 0.359) and PaO2 (r = 0.355) showed positive correlations (p < 0.05, for all variables). Blood selenium concentrations were significantly lower in patients with SIRS than in those patients without SIRS (8.08 +/- 2.42 vs. 9.45 +/- 2.02, p = 0.011). Patients with severe sepsis and septic shock had showed significantly lower blood selenium concentrations than those without SIRS (7.03 +/- 2.73 vs. 9.45 +/- 2.02, p = 0.042). Patients with PaO2/FiO2 < or = 300 had lower blood selenium concentrations than those with PaO2/FiO2 > 300 (7.90 +/- 2.43 vs. 9.54 +/- 2.17, p = 0.018). Blood selenium concentrations were significantly lower in patient with PaO2/FiO2 < or = 200 than in those with PaO2/FiO2 > 300 (7.64 +/- 2.76 vs. 9.54 +/- 2.17, p = 0.018).
CONCLUSIONS
Patients with systemic inflammatory response syndrome or respiratory dysfunction showed significantly low blood selenium concentrations.

Abstract PDF

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortalities. Each type of blood product is likely to cause TRALI. Patients with TRALI present with dyspnea/respiratory distress and fever. The symptoms, signs and chest radiological findings in TRALI are similar to transfusion associated circulatory overload. Therefore, it is difficult to distinguish such from circulatory overloads. We report a case of TRALI in a 49-year-old woman after stored packed red blood cell transfusion. The patient developed hypoxemia and pulmonary edema after packed red blood cell transfusion during postoperative period. The patient completely recovered after an oxygen support for 3 days.

Abstract PDF: BACKGROUND
If acid-base status and electrolytes on blood gases during cardiopulmonary resuscitation (CPR) differ between the arrest causes, this difference may aid in differentiating the arrest cause. We sought to assess the ability of blood gases during CPR to predict the arrest cause between primary cardiac arrest and asphyxial arrest.
METHODS
A retrospective study was conducted on adult out-of-hospital cardiac arrest patients for whom blood gas analysis was performed during CPR on emergency department arrival. Patients were divided into two groups according to the arrest cause: a primary cardiac arrest group and an asphyxial arrest group. Acid-base status and electrolytes during CPR were compared between the two groups.
RESULTS
Presumed arterial samples showed higher potassium in the asphyxial arrest group (p < 0.001). On the other hand, presumed venous samples showed higher potassium (p = 0.001) and PCO2 (p < 0.001) and lower pH (p = 0.008) and oxygen saturation (p = 0.01) in the asphyxial arrest group. Multiple logistic regression analyses revealed that arterial potassium (OR 5.207, 95% CI 1.430-18.964, p = 0.012) and venous PCO2 (OR 1.049, 95% CI 1.021-1.078, p < 0.001) were independent predictors of asphyxial arrest. Receiver operating characteristic curve analyses indicated an optimal cut-off value for arterial potassium of 6.1 mEq/L (sensitivity 100% and specificity 86.4%) and for venous PCO2 of 70.9 mmHg (sensitivity 84.6% and specificity 65.9%).
CONCLUSIONS
The present study indicates that blood gases during CPR can be used to predict the arrest cause. These findings should be confirmed through further studies.

Abstract PDF

Transfusion-related acute lung injury (TRALI) is a significant cause of iatrogenic injuries in patients. It is also the major cause of transfusion-associated fatalities. Pathophysiologic mechanism is an implicated donor of HLA. Neutrophil antibodies and biologic response modifiers are accumulated in the stored blood products. Pulmonary endothelial activation of the host may be the response from these mediators. Treatment is supportive and will be subjected to other forms of ALL/ARDS. Diverting donors at high risk for alloimmunization may decrease the incidence of such cases.

Abstract PDF: Acute viral bronchiolitis (AVB) is an obstructive lung disease which frequently develops in infants and the most common functional involvement is a V/Q ratio change caused by small airway obstruction. We report a case showing the redistribution of pulmonary blood flow by multiple perfusion scan defects in an infant with AVB. A 15 month-old male infant visited ER due to respiratory difficulty. He manifested decreased lung sound in the left lung field, hyperinflation of the left lung on chest x-ray, and metabolic acidosis in blood gas analysis. A perfusion scan showed multiple perfusion defects of both lungs without the evidence of pulmonary embolism on a following cardiac CT and echocardiography. Human Rhinovirus PCR in a nasopharyngeal aspirate was positive. With supportive care, the symptom was resolved in 4 days. AVB can show multiple perfusion defects by the redistribution of pulmonary blood flow of which the direction is opposite to the usual distribution of pulmonary blood flow in children.

Abstract PDF

Transfusion-related acute lung injury (TRALI) is a serious complication following the transfusion of blood products. TRALI is under-diagnosed and under-reported because of a lack of awareness. TRALI occurs within 6 hours of transfusion in the majority of cases and its presentation is similar to other forms of acute lung injury. We report on the case of a 34-year-old pregnant woman who suffered from TRALI after transfusion during Cesarean section.

Abstract PDF: BACKGROUND
Tracheal intubation stimulates the sympathetic nervous system, resulting in hypertension, tachycardia and sometimes critical complications, especially in patients with underlying hypertension, cardiovascular disease or cerebrovascular disease. In this study, we sprayed 4% lidocaine into the trachea before intubation, and observed the hemodynamic changes after tracheal intubation.
METHODS
We randomly allocated 87 patients, whose ASA physical status was I or II, into three groups. The 4% topical lidocaine was sprayed before intubation at the following specific times: just before intubation (group 0), or 1 minute (group 1) and 2 minutes before intubation (group 2). For maintenance of anesthesia, TIVA (total intravenous anesthesia; propofol-remifentanil infusion with orchestra(R)) was used. We observed hemodynamic changes between the groups just after the intubation, as well as 1, 3 and 5 minutes after the intubation. Hemodynamic changes were also monitored in the same group.
RESULTS
When the patients arrived at the operating room, we found no significant difference in heart rate and arterial pressure between the groups. However, heart rate after intubation in group 1 was significantly lower than group 0. The diastolic and mean arterial pressure just after intubation were lower in group 1 and 2 than in group 0.
CONCLUSIONS
Spraying lidocaine 1 or 2 minutes before intubation was more effective than spraying it just before intubation for reducing hypertensive responses after intubation.

Abstract PDF: Jehovah's Witnesses refuse the transfusion of blood and blood products, even when it can be lifesaving. Their religious conviction against receiving blood can create a difficult clinical dilemma, particularly in the life threatening situations. We report a case of a 42-year-old female Jehovah's Witness patient who had life-threatening anemia after postpartum hemorrhage. Despite severe anemia, she had a good postoperative recovery without complications.

Abstract PDF

BACKGROUND
This study was performed to evaluate whether blood glucose concentrations have a significant influence on acid-base balance.
METHODS
We studied 157 adult patients who underwent intra-abdominal operations under general anesthesia. Postoperative blood samples were withdrawn from radial artery and blood glucose concentrations, gas values, and chemistry values were measured. All patients were divided into three groups according to the postoperative blood glucose level. The group 1 contained the patients who had postoperative blood glucose level lower than 126 mg/dl, the group 2, the patients with glucose level higher than 126 mg/dl, lower than 180 mg/dl, and the group 3, the patients with glucose level higher than 180 mg/dl.
RESULTS
Metabolic acidosis rate was significantly higher in group 3 than in group 1, group 2 and arterial blood pH was significantly lower in group 3 than that in group 1, group 2. Regression analysis showed that [H+] was correlated with blood glucose level. Strong ion difference (SID) was significantly lower in group 3 than group 1 and PaCO2 level was significantly lower in group 2 and group 3 than that in group 1. In regression analysis, there was a negative correlation between blood glucose concentration and SID. [H+] had a negative correlation with SID and PaCO2 was correlated with SID.
CONCLUSIONS
These findings suggest that blood glucose level affects acid-base balance and a disturbance in SID is accompanied with respiratory compensation.

Abstract PDF

BACKGROUND
Blood pressure is clinically used for monitoring shock patients and as a therapeutic indicator for them. Non-invasive blood pressure measurement has weak points such as the use of a cuff and it is a discontinuous measurement. A method of measuring the blood pressure by using the PWTT (pulse wave transit time) has been studied to make up for those weak points. If blood pressure monitoring can be done by using the difference of the PWTT between different points in the body, then this method will be a quite useful to monitor the BP of seriously ill patients. This study aimed to verify whether or not the PWTT has a significant correlation with the blood pressure of shock patients who received vasopressor infusion and whether this method is clinically applicable.
METHODS
The study subjects were 20 shock patients who were hospitalized in intensive care units and they had received vasopressor, and we measured the PWTT and we analyzed its correlation with the SBP (systolic blood pressure) and DBP (diastolic blood pressure), as measured by non-invasive monitoring. We then determined the effects of the PWTT on the SBP and DBP.
RESULTS
From the results of correlation analysis between the PWTT and the SBP and DBP, the SBP displayed a statistically significant negative correlation with the PWTT of 18 patients, while no significant correlation between the PWTT and DBP was observed. At the same time, from the results of the regression analysis of the blood pressures and the PWTT of each patient, it was found that the PWTT had a negative effect on the SBP of all the patients, except two.
CONCLUSIONS
The PWTT has a negative correlation with the SBP of the patients who received vasopressor infusion.

Abstract PDF: BACKGROUND
Patients with major burns require replacement of intravascular volume. Hydroxyethyl starch (HES) solutions are widely used to replace intravascular volume. Dilution with crystalloids or colloids and corresponding platelet dysfunction are known causes of perioperative bleeding tendencies. The aim of the current study was to evaluate the effect of crystalloid and colloid solutions on platelet function in patients with major burns.
METHODS
Forty patients scheduled for burn surgery were divided into 4 groups. The infusion was started with a Hartman solution infusion (group 1) from 7 A.M. until surgery. HES (6%, Voluven(R)) was infused in the following concentrations: 7 ml/kg (group 2), 10 ml/kg (group 3), and 15 ml/kg (group 4). The bleeding time (BT), prothrombin time (PT), prothrombin time international ratio (PT INR), activated partial thromboplastin time (aPTT), hemoglobin (Hb), platelet function analyzer-100 closing time (PFA CT), and platelet count (Plt) were measured.
RESULTS
Hartmann solution and HES had no significant effect on the BT, PT, PT INR, a PTT, Hb, and Plt. The post-operative PFA CT was significantly higher in group 4 than in group 3. In group 4, the PFA CT was significantly higher post-operatively compared to pre-operatively.
CONCLUSIONS
The use of high dose HES may increase the risk of bleeding tendencies in burn patients.

Abstract PDF: BACKGROUND
Prone positioning has been adopted as a strategy to improve oxygenation in patients with refractory acute respiratory distress syndrome (ARDS). After returning to supine position, most of patients show arterial blood gas changes. However, the clinical implications have not been elucidated. This study was aimed to observe the relationship between the arterial blood gas changes followed by changing position from prone to supine and survival of ARDS.
METHODS
We analyzed medical data of 53 ARDS patients, who showed improved arterial oxygenation (defined as the increase in PaO2/FiO2 by > or =20 mmHg within 8~12 hour after prone positioning) in a medical intensive care unit from January, 2000 to July, 2006. The patients were returned to supine position when they showed their PaO2/FiO2 > or =150 mmHg. We compared the arterial blood gas changes between the survivor and the nonsurvivor.
RESULTS
The survivor has significant pH improvement after position change (the survivor 0.01+/-0.06 vs. the nonsurvivor -0.03+/-0.08; p=.03). The PaO2/FiO2 and FiO2 changes were not different between the survivor (14.44 +/-69.68 and -2.2+/-4.3, respectively) and the nonsurvivor (-7.17+/-83.94 and 1.8+/-6.0, respectively; p=.314 and .843). The patients whose PaO2/FiO2 were deteriorated had higher mortality without statistical significance (p=.305). The PaCO2 changes were not different between two groups (-0.05+/-11.46 vs. 3.47+/-17.62, p=.390).
CONCLUSIONS
The early changes in pH differed significantly between the survivor and the nonsurvivor after returning patients to supine position from prone. Whether this marker can be a predictor of survival should be studied further.

Abstract PDF: Spontaneous intracranial hypotension (SIH) is a syndrome of low cerebrospinal fluid pressure characterized by postural headaches in patients without any history of dural puncture, back trauma, operative procedure, or medical illness. The clinical spectrum of SIH is quite variable and includes headache, neck stiffness, nausea, horizontal diplopia, dizziness, tinnitus, visual blurring, radicular arm pain. When the headache persists or more incapacitating, more aggressive treatment may be necessary. Autologous epidural blood patch is used in the management of SIH and highly effective. I experienced a case of 39 year old female with postural headache and tinnitus who was diagnosed as having SIH and successfully treated with epidural blood patch.

Abstract PDF: BACKGROUND
Cerebral hyperperfusion syndrome is a recognized complication of carotid endarterectomy, with a reported incidence of 0.3 to 1.2%. Monitoring of regional cerebral blood flow (rCBF) may limit neurological damage. This study was planned to investigate the changes of rCBF according to inhalational anesthetic agents. METHODS: 2.40+/-0.04 kg weighed New Zealand White Rabbits were undergone transient brain ischemia by bilateral carotid artery ligation for 20 minutes. The rCBF was measured by Bowman Perfusion Monitor.
RESULTS
The value of rCBF in pre-ligation state was not significantly different among the three groups. rCBF in sevoflurane group was decreased to 46% of baseline value during ischemia and increased to 143% just after reperfusion. rCBFs in isoflurane and enflurane groups were abruptly increased instead of decrease like sevoflurane group. The values of rCBF was more increasing after reperfusion in isoflurane and enflurane groups. rCBFs in all groups were return to baseline value 10 minutes after reperfusion. CONCLUSIONS: This results was suggested that sevoflurane might be contributed to create a neurologic damage during ischemia and the hyperperfusion was seen in all three anesthetic agents. The clinical investigation may be needed to establish the value of this experiment.

Abstract PDF: BACKGROUND
To assess the acid-base status and to measure PO2 and PCO2, arterial blood gases (ABG) has been checked usually. We compared the venous blood gases (VBG) from dorsal vein of hand to ABG from radial artery, and tried to determine whether venous blood gas analysis (VBGA) could be the alternative of ABGA. METHODS: Thirty patients who needed continuous arterial pressure monitoring were chosen. At the completion of stability of HR and BP after induction of general inhalational anesthesia, the ABG from radial artery and VBG from dorsal vein of hand were compared. RESULTS: Laboratory findings were as follows (mean+/-SD): arterial pH, 7.44+/-0.04; venous pH, 7.43+/-0.04; arterial HCO3-, 25.56+/-2.39 mmol/L; venous HCO3-, 25.51+/-2.09 mmol/L. The mean values of arterial and venous PO2 were significantly different (247.8+/-48.9 mmHg versus 187.8+/-41.6 mmHg), but the arterial and venous PO2 values were significantly correlated (r=0.706). The PCO2 (r= 0.883), pH (r=0.912), and HCO3- (r=0.901) values, and base excesses of arterial and venous blood (r=0.926) were highly correlated. Also, arterial and venous serum electrolyte (sodium, potassium, and calcium) were highly correlated. CONCLUSIONS: Venous blood gas analysis from dorsal vein of hand can be effectively used as the alternative method to evaluate the acid-base status, PO2, and PCO2, instead of ABGA during general inhalational anesthesia.

Abstract PDF: BACKGROUND
To analyze hemodynamic changes during single catheter technique of hepatic venous isolation and extracorporeal charcoal hemoperfusion for malignant liver tumor. METHODS: Drugs for chemotherapy were infused to the liver through hepatic artery. With 4-lumen- 2-balloon (4L-2B) catheter, hepatic venous blood was circulated to the extracorporeal charcoal system. During extracorporeal charcoal system circulation, drugs were eliminated and the blood was reinfused to supra-hepatic vein-IVC. At the same time, IVC was clamped. Systemic vascular resistance index (SVRI), cardiac index (CI), stroke volume index (SVI), mean arterial pressure (MAP), heart rate (HR) and arterial blood gas were measured after 4L-2B catheter insertion (T1), during test circulation (T2), after 20min chemotherapy (T3) and after 10min reperfusion (T4). RESULTS: MAP was decreased at T3 compared to T1 and increased at T4 compared to T3. CI was decreased at T3 and increased at T4 compared to T1. SVRI was decreased at T4 compared to T1. HR was increased at T2 and T3 compared to T1. SVI was decreased at T2 and T3 compared to T1. CONCLUSIONS: During clamping of IVC, MAP is decreased by decreased SVI in spite of increased HR. After IVC is released and the stagnated blood of lower extremity is recirculated, the MAP is returned to the value of after catheter insertion by increased SVI in spite of decreased SVRI.

Abstract PDF: BACKGROUND
The blood components of priming solution for cardiopulmonary bypass (CPB) may have opposite roles for tissue perfusion, which are the activation of inflammatory reaction and the improvement of oxygen carrying capacity. This study is aimed to investigate the effect of blood transfusion of priming solution on inflammatory response and tissue perfusion. METHODS: Twenty mongrel dogs randomly allocated and received hypothermic CPB with blood- containing (H group, n=10), or non-hemic (NH group, n=10) priming solution. Gastric intramucosal CO2 concentration (PrCO2), intramucosal pH (pHi), interleukin-8 (IL-8), blood gas and hemodynamic parameters were measured at 1) before CPB, 2) 1 hour during CPB, 3) the end of CPB, 4) 2 hours after CPB, 5) 4 hours after CPB. The ratio of wet to dried lung weight was measured. Statistical verification was performed using repeated measures ANOVA and unpaired t-test.
RESULTS
PrCO2 increased and pHi decreased during the study without significant difference between the groups. IL-8 increased in both groups and IL-8 of H group increased higher than that of NH group during the study. The difference between PaCO2 and end-tidal CO2 of NH group was higher than that of H group at 4 hours after CPB. The ratio of wet to dried lung weight was not significantly different between the groups. CONCLUSIONS: We conclude that the allogenic blood in priming solution aggravates the CPB- induced inflammatory reaction, however, the CPB-induced impairment of gastric mucosal perfusion and the pulmonary edema are not significantly affected, compared to non-hemic solution.

Abstract PDF: Introduction: Lactic acid in circulating blood should provide an index between balance of oxygen consumption and metabolic rate in sepsis or any state of shock. The purpose of the study was to determine the prognostic power of the lactate, the time factor of the blood lactate levels between survivors and non-survivors and the correlation between APACHE III score and blood lactate level in SIRS patients.
METHOD
The study was performed on 99 patients over 16 years old who were admitted to the SICU with the criteria of SIRS. The blood lactate concentrations were assayed with arterial blood drawn in intervals ranging from 4 to 24 hours and the APACHE III scoring was done in the first 24 hours of SICU admission and daily until discharge or death for 2 weeks. The highest lactate level of the day was recorded. They were divided into two groups, survivors (n=61) and non-survivors (n=38), according to the outcome.
RESULT
There were significant difference of the first day (D1) as well as peak lactate level between the survivors and the non-survivors (3.02 3.05 vs 7.41 4.78, 3.24 2.70 vs 7.82 4.88 mmol/L). Significant difference of the lactate as well as APACHE III were identified between the survivors and the non-survivors during a 14-days of observation period. Significant correlations were shown between lactate and APACHE III while the study was being conducted. The peak lactate presented superior to the D1 lactate in mortality prediction.
CONCLUSION
Blood lactate concentration could be used as a prognostic index as well as APACHE III score. Serial blood lactate concentration assays are necessary to predict the outcome.

Abstract PDF: BACKGROUND
Norepinephrine, which is frequently administered as a vasopressor to the patients with septic shock, can decrease splanchnic and renal blood flows and aggravate splanchnic and renal ischemia. The low-dose dopamine (LDD) has been frequently combined with norepinephrine to ameliorate renal and splanchnic hypoperfusion in patients with septic shock. However, the effect of the LDD on the splanchnic and renal blood flow has not been fully elucidated. This investigation was carried out to determine the effect of the LDD on the splanchnic and renal blood flow in the patients with septic shock under the treatment of norepinephrine.
METHODS
Eleven patients with septic shock were included in this study. All of them were under the norepinephrine treatment as the mean arterial pressure (MAP) was less than 70 mm Hg in spite of the adequate fluid resuscitation. With stabilization of MAP, the LDD (2 g/kg/min) was administered for two hours in each patients. Hemodynamics, gastric intramucosal pH (pHi), gastric regional PCO2 (rPCO2), rPCO2 - PaCO2, urine volume, urine sodium excretion and creatinine clearance were compared between with and without the LDD infusion. Diuretics was not used during the study period.
RESULTS
Age of patients (n=11) was 64 12 and the APACHE III score was 84 17. The mortality rate of the subjects was 64%. Dosage of norepinephrine was 0.55 0.63 g/kg/min during the study period. There were no significant differences in hemodynamics (central venous pressure, cardiac output, pulmonary artery occlusion pressure, mixed venous gas), pHi, rPCO2, rPCO2 - PaCO2 depending on the concomitant infusion of the LDD. The volume of urine tended to increase (P=0.074) after concomitant LDD, but the changes in urine sodium excretion and creatinine clearance were not significantly different.
CONCLUSIONS
The combined infusion of the LDD with norepinephrine did not improve splanchnic and renal blood flow in the patients with septic shock.

Abstract PDF: BACKGROUND
Pulmonary artery ligation during pneumonectomy increase the pulmonary blood flow of dependent lung and may increase the pulmonary arterial pressure and pulmonary vascular resistance. The purpose of this study is to evaluate the hemodynamic effect of pulmonary artery ligation during pneumonectomy.
METHODS
Nine patients who were supposed to receive pneumonectomy were studied. Hemodynamic measurements were performed following two lung ventilation (TLV), one lung ventilation (OLV), after pulmonary artery ligation and after pneumonectomy.
RESULTS
There is no significant differences in heart rate, systemic arterial pressure, pulmonary arterial pressure, pulmonary capillary wedge pressure, cardiac index and pulmonary vascular resistance index. Arterial oxygen tension significantly reduced during OLV and increased after pulmonary artery ligation and after pneumonectomy.
CONCLUSIONS
These results suggest that pulmonary artery ligation during pneumonectomy may not affect the cardiopulmonary hemodynamics.

Abstract PDF: BACKGROUND
The development of so-called "Point-of-care" (POC) devices for blood or urine analysis has resulted in many systems that are widely used at home or at the bedside. We evaluated the performance of the I-STAT portable clinical analyzer for measuring blood gases (pH, PCO2, PO2) and whole blood electrolytes (sodium, potassium and ionized calcium) with reference to a conventional blood gas analyzer (Chiron 348 pH/ blood gas/electrolytes).
METHODS
Thirty samples from the arterial blood were simultaneously analyzed with I-STAT system and with Chiron 348 pH/blood gas/ electrolytes analyzer. Differences between results of two methods were analyzed by paired t-test (p<0.05).
RESULTS
PO2, PCO2 and Na measured with I-STAT system and Chiron 348 PH/ blood gas/ electrolytes analyzer showed no significant differences. pH, calculated HCO3, K and Ca measured by two methods showed significant difference, but observed differences would not affect clinical decisions except ionized calcium.
CONCLUSIONS
This study shows that blood gas and electrolyte analysis using the I-STAT portable device is comparable with that performed by a conventional Chiron 348 pH/blood gas/ electrolytes analyzer except ionized calcium.

Abstract PDF: BACKGOUND: Disruption of the blood-brain barrier (BBB) can alter the internal milieu and may increase the release of excitatory amino acid neurotransmitters or catecholamines, which may affect metabolic rate or coupling. This study was performed to evaluate whether disruption of BBB by unilateral intracarotid injection of hyperosmolar mannitol would alter oxygen supply/consumption balance in the ipsilateral cortex.
METHODS
Rats were anesthetized with 1.4% isoflurane using mechanical ventilation via tracheostomy. 25% mannitol was administered at a rate of 0.25 mlxkg-1s-1 for 30 s through unilateral internal carotid artery. The BBB transfer coefficient (Ki) of 14C-alpha-aminoisobutyric acid was measured in one group (N=7) after administering mannitol. Regional cerebral blood flow (rCBF), regional arterial and venous O2 saturation and O2 consumption were measured in another group using a 14C-iodoantipyrine and microspectrophotometry (N=7).
RESULTS
Vital signs were similar before and after administering mannitol. Ki was significantly higher in the ipsilateral cortex (IC) than in the contralateral cortex (CC), (22.3+/-8.4 vs 4.4+/-1.1 microliterxg-1min-1). rCBF was similar between IC (105+/-21 mlxg-1min-1) and the CC (93+/-20). Venous O2 saturation was lower in the IC (43+/-7%) than in the CC (55+/-4). O2 consumption was higher in the IC (9.6+/-3.0 mlx100 g-1min-1) than in the CC (6.7+/-1.5).
CONCLUSIONS
Our data suggested that increasing permeability of the BBB increased cerebral O2 consumption and deteriorated cerebral oxygen balance.

Abstract PDF: BACKGOUND: Transfusion of red blood cells is a life saving measure in the management of a variety of surgical conditions. A guideline for blood transfusion during elective surgical procedure is necessary to reduce the risks of transfusion-associated complications, excessive blood bank workload, excessive blood request and overtransfusion, and the cost. From this, a program of quality assessment was adopted to improve blood transfusion practice and to establish the guideline for blood transfusion in elective surgery at Pusan National University Hospital.
METHODS
Fifty-six patients undergoing elective surgery was divided 2 groups. Transfusion (T) group was 18 persons. Non-transfusion (NT) group was 38 persons. The preoperative, pre-transfusion, postoperative, and post-transfusion hemoglobin (Hb), hematocrit, mean arterial blood pressure (MAP), heart rate (HR), average amount of transfused red blood cell units, allowable blood loss, and the amount of infused crystalloids and colloids was estimated for 9 months in Pusan National University Hospital.
RESULTS
There were no significant differences in Hb between T & NT group. Hb decreased significantly until postoperative 3rd day in NT group. Platelet count decreased in NT group on postop. 3rd day. There were no significant differences in MAP & HR. One-ninth of T group was overestimated blood loss & 18.4% of NT group was underestimated blood loss. One-third of transfusion patient were overtransfused & 36.2% of transfused RBC was unnecessary. Nearly 90% of patient was transfused packed RBC with FFP concurrently.
CONCLUSIONS
To minimize overtransfusion, transfusion based on intraoperative hematocrit is necessary. If possible, single use of packed RBC is recommended when the blood loss is below allowable blood loss. In massive bleeding above allowable blood loss, combined administration of FFP and packed RBC or transfusion of whole blood will be better.

Abstract PDF: BACKGOUND: Mass casualties from organophosphorus inhalation die from respiratory depression. Gas supplies and equipment are limited for mechanical ventilation of multiple subjects in emergency situation. Endobronchial insufflation of air (EIA) can be simply performed with air compressor and catheter. The author tried to examine the usefulness of EIA in five apneic dogs induced by tetrodotoxin (TTX) infusion.
METHOD
Five anesthetized dogs were intubated with endotracheal tube and endobronchial insufflation catheter and instrumented with arterial catheter and ventilated with controlled mechanical ventilation (CMV) while 12 microgram/kg TTX was infused intravenous over 90 minutes to produce apnea. EIA of 1 microliter/kg/min was delivered through a 35 cm long, 0.8 cm ID catheter with a forked end placed astride the carina. During conventional ventilation, arterial blood gases and pH were measured (base line, BL). The data were measured after confirmation of apnea for 1 minute (time=0, control value), and then measured serially for 4 hours of EIA.
RESULT
All animals survived and were alert and neurologically normal within 24 hours. The changes of arterial oxygen tension (PaO2) were no significant difference between control value and 10, 20, 30 minute (p<0.05), and arterial carbon dioxide tension (PaCO2) were significant increase in control value compared to base line (p<0.05), and pH were no significant difference in all values (p<0.05). Spontaneous respiratory efforts slowly returned after 45 minute of EIA and resulted in the improvement of gas exchange.
CONCLUSION
EIA recognized as a sort of ventilatory technique is useful only when other equipments could not be available. The EIA catheter can be placed by cricothyroidotomy. EIA is very helpful in supporting ventilation, and it also helps the apneic dogs stay in normal condition.

Abstract PDF: Intraoperative massive bleeding requires fluid therapy and blood transfusion. But transfusion may elicit infection, hemolytic reaction, hemostatic disorder and other complication. Individuals often produce antibodies to the alleles which lack in ABO and Rh system. Such antibodies are responsible for the most serious reaction to transfusions. Antibodies may occur "naturally" or in response to sensitization from a previous transfusion or pregnancy. We report a case of severe anemic patient who had Anti Ce due to previous transfusion and was not transfused for several hours because of incompatible cross-matching. His Rh phenotype is revealed cDE.

Abstract PDF: BACKGOUND: Postoperative complications in the geriatric patients undergoing radical neck dissection are generally considered to be more severe than young patients. The incidence of carotid sinus hypersensitivity in elderly patients is also considered to be higher than the young. The comparison between old (above 65 years) and young (below 65 years) aged groups about intraoperative carotid sinus hypersensitivity and postoperative complication is necessary for safe anesthesia.
METHODS
Sixty five adult patients, of either sex, regardless of age, given radical neck dissection from January 1990 to January 1998, were investigated for the incidence of intraoperative carotid sinus hypersensitivity and postoperative hypertension by way of retrospective chart review. The authors also examined the postoperative complications such as high fever, pulmonary, cardiac and renal complications, cerebrovascular diseases and neurologic injuries.
RESULTS
The incidence of intraoperative carotid sinus hypersensitivity were 28% in elderly patients (n=25), 10% in young patients (n=40) but there was no statistical significance. The incidence of postoperative hypertension were 79.1% in patients with hypertension history, 34.1% in patients without hypertension history and there was statistical significance between the two groups (P=0.001). The incidence of postoperative pulmonary complication were 44% in elderly patients, 20% in young patients, and there was also statistical significance between the two groups (P=0.038). There was no statistical significance in the incidence of postoperative high fever above 38.5degrees C between the two groups (p=0.059).
CONCLUSION
After the radical neck dissection, the geriatric patients had a greater incidence of postoperative pulmonary complications than young patients and the most relating factor to postoperative hypertension was previous history of hypertension. Therefore optimal preoperative preparations for the hypertensive patients and the prevention and immediate treatment of the postoperative pulmonary complications in geriatric patients are very important during the radical neck dissection.

Abstract PDF: Blood loss is usually replaced with crystalloid or colloid solutions until a predetermined minimal hematocrit is reached. But in severe blood loss, blood transfusion is indicated for maintenance of oxygen-carrying capacity, coagulation factors and intravascular volume. Jehovah's witness patients refuse blood transfusion, but some patients with rare blood type may even not have the chance of blood transfusion. Commonly utilized and effective alternatives to blood transfusion are acute hemodilution, autotransfusion and other blood salvage techniques. We report a case of successful anesthetic management in patient of hemorrhagic shock with rare blood type (Rh-, AB type) without blood trasfusion.

Abstract PDF: BACKGOUND: The barrier can be altered by a number of insults to the brain (e.g., hypertension, freezing, trauma, drug). But the effect of the blood brain barrier distruction immediately after the neural change is unknown. In the present study, we focused on the BBBD after cervical sympathetic chain block.
METHODS
13 male Sprague-Dawley rats were divided into 2 groups. Group 1 (N=7) was blocked with 0.5% bupivacaine on the right cervical sympathetic chain and group 2 (N=6) was blocked with 0.5% bupivacaine on the bilateral cervical sympathetic chain. All rats received 37degrees C, 25% mannitol (1.75 g/kg) via right carotid artery and then, the effect of cervical sympathetic chain block on blood-brain barrier disruption of four cerebral compartment using 99mTc-human serum albumin and Evans blue was evaluated.
RESULTS
Both groups showed blood-brain barrier disruption and there was no significant difference between group 1 and group 2 in the anterior and posterior hemisphere of the right side brain. But group 2 showed significant blood-brain barrier disruption than group 1 in anterior and posterior hemisphere of the left brain (p<0.01).
CONCLUSIONS
This results suggest that cervical sympathetic chain block can increase the degree of mannitol-induced blood-brain barrier disruption via neural arch or blood flow change.

Abstract PDF: BACKGOUND: Arterial blood gas analysis is essential on diagnosis and treatment of hypoxia and acid-base imbalance. It is important to decide the timing of arterial blood sampling as well as sampling method, sample transport, and analysis of the results. So we investigated to the adequate timing of sampling when inspired oxygen fraction is changed from 0.5 to 1.0.
METHODS
20 patients were anesthetized with enflurane-N2O-O2 (FiO2=0.5), and paralyzed with pancuronium 0.07~0.08 mg/kg. Ventilation was controlled with Ohmeda 7000 ventilator (BOC Health Care Inc., Madison, USA), using a constant tidal volume of 10 ml/kg and respiration rate of 12/min. After 1 hour of anesthesia, the nitrous oxide inhalation was stopped and 100% oxygen was inhaled, and then arterial blood gas values were measured at 2 min intervals for 20 min, 5 min intervals for next 30 min, and 10 min later. Blood samlpes were drawn from the radial artery and measured immediately on a blood gas analyzer (Civa-Corning 288 Blood Gas System, Civa-Corning Diagnostic Corp., Medifield, USA). Determining the optimal time of sampling was performed with the rate of variation of PaO2 according to time progression, then the point at which the slope decreased abruptly was regarded as statistically significant timing.
RESULTS
After 12 minute, arterial oxygen partial pressure was not any more changed significantly. There were no change of pH, arterial carbon dioxide partial pressure, oxygen saturation, base excess, and bicarbonate.
CONCLUSION
The timing of arterial blood gas sampling in change with inspired oxygen fraction from 0.5 to 1.0 is about 12 minute later.
