Background
The objective of this study was to investigate the characteristics and clinical outcomes of critically ill cancer patients admitted to intensive care units (ICUs) in Korea.
Methods
This was a retrospective cohort study that analyzed prospective collected data from the Validation of Simplified Acute Physiology Score 3 (SAPS3) in Korean ICU (VSKI) study, which is a nationwide, multicenter, and prospective study that considered 5,063 patients from 22 ICUs in Korea over a period of 7 months. Among them, patients older than 18 years of age who were diagnosed with solid or hematologic malignancies prior to admission to the ICU were included in the present study.
Results
During the study period, a total of 1,762 cancer patients were admitted to the ICUs and 833 of them were deemed eligible for analysis. Six hundred fifty-eight (79%) had solid tumors and 175 (21%) had hematologic malignancies, respectively. Respiratory problems (30.1%) was the most common reason leading to ICU admission. Patients with hematologic malignancies had higher Sequential Organ Failure Assessment (12 vs. 8, P<0.001) and SAPS3 (71 vs. 69, P<0.001) values and were more likely to be associated with chemotherapy, steroid therapy, and immunocompromised status versus patients with solid tumors. The use of inotropes/ vasopressors, mechanical ventilation, and/or continuous renal replacement therapy was more frequently required in hematologic malignancy patients. Mortality rates in the ICU (41.7% vs. 24.6%, P<0.001) and hospital (53.1% vs. 38.6%, P=0.002) were higher in hematologic malignancy patients than in solid tumor patients.
Conclusions
Cancer patients accounted for one-third of all patients admitted to the studied ICUs in Korea. Clinical characteristics were different according to the type of malignancy. Patients with hematologic malignancies had a worse prognosis than did patients with solid tumor.

Abstract PDF

There is no well-stated practical guideline for mechanically ventilated patients with or without acute respiratory distress syndrome (ARDS). We generate strong (1) and weak (2) grade of recommendations based on high (A), moderate (B) and low (C) grade in the quality of evidence. In patients with ARDS, we recommend low tidal volume ventilation (1A) and prone position if it is not contraindicated (1B) to reduce their mortality. However, we did not support high-frequency oscillatory ventilation (1B) and inhaled nitric oxide (1A) as a standard treatment. We also suggest high positive end-expiratory pressure (2B), extracorporeal membrane oxygenation as a rescue therapy (2C), and neuromuscular blockage for 48 hours after starting mechanical ventilation (2B). The application of recruitment maneuver may reduce mortality (2B), however, the use of systemic steroids cannot reduce mortality (2B). In mechanically ventilated patients, we recommend light sedation (1B) and low tidal volume even without ARDS (1B) and suggest lung protective ventilation strategy during the operation to lower the incidence of lung complications including ARDS (2B). Early tracheostomy in mechanically ventilated patients can be performed only in limited patients (2A). In conclusion, of 12 recommendations, nine were in the management of ARDS, and three for mechanically ventilated patients.

Abstract PDF: Background
Pneumothorax (PTX) can occur as a complication of positive pressure ventilation in mechanically ventilated patients.
Methods
We retrospectively reviewed the clinical characteristics of patients who developed PTX during mechanical ventilation (MV) in the intensive care unit (ICU).
Results
Of the 326 patients admitted (208 men and 118 women; mean age, 65.3 ± 8.74 years), 15 (4.7%) developed PTX, which was MV-associated in 11 (3.3%) cases (6 men and 5 women; mean age, 68.3 ± 9.12 years) and procedure-associated in 4. Among the patients with MV-associated PTX, the underlying lung diseases were acute respiratory distress syndrome in 7 patients, interstitial lung disease in 2 patients, and chronic obstructive pulmonary disease in 2 patients. PTX diagnosis was achieved by chest radiography alone in 9 patients and chest computed tomography alone in 2 patients. Nine patients were using assist-control mode MV with the mean applied positive end-expiratory pressure, 9 ± 4.6 cmH₂O and the mean tidal volume, 361 ± 63.7 ml at the diagnosis of PTX. Two patients died as a result of MV-associated PTX and their systolic pressure was below 80 mmHg and heart rates were less than 80/min. Ten patients were treated by chest tube insertion, and 1 patient was treated by percutaneous pigtail catheter insertion.
Conclusions
PTX can develop in patients undergoing MV, and may cause death. Early recognition and treatment are necessary to prevent hemodynamic compromise in patients who develop PTX.

Abstract PDF: BACKGROUND
Acute respiratory failure can occur paradoxically on initiation of anti-tuberculosis (TB) treatment in patients with pulmonary TB. This study is aimed to analyze the clinical features of anti-TB treatment induced acute respiratory failure.
METHODS
We reviewed the clinical and radiological characteristics of 8 patients with pulmonary tuberculosis (5 men and 3 women; mean age, 55 +/- 15.5 years) who developed acute respiratory failure following initiation of anti-TB medication and thus required mechanical ventilation (MV) in the intensive care unit (ICU).
RESULTS
The interval between initiation of anti-TB medication and development of MV-requiring acute respiratory failure was 2-14 days (mean, 4.4 +/- 4.39 days), and the duration of MV was 1-18 days (mean, 7.1 +/- 7.03 days). At admission, body temperature and serum levels of lactate dehydrogenase and C-reactive protein were increased. Serum levels of protein, albumin and creatinine were 5.8 +/- 0.98, 2.3 +/- 0.5 and 1.8 +/- 2.58 mg/ml, respectively. Radiographs characterized both lung involvements in all patients. Consolidation with the associated nodule was noted in 7 patients, ground glass opacity in 2, and cavitary lesion in 4. Micronodular lesion in the lungs, suggesting miliary tuberculosis lesion, was noted in 1 patient. At ICU admissions, the ranges of the APACHE II and SOFA scores were 17-38 (mean, 28.2 +/- 7.26) and 6-14 (mean, 10.1 +/- 2.74). The mean lung injury score was 2.8 +/- 0.5. Overall, 6 patients died owing to septic shock and multiorgan failure.
CONCLUSIONS
On initiation of treatment for pulmonary TB, acute respiratory failure can paradoxically occur in patients with extensive lung parenchymal involvement and high mortality.

Abstract PDF: BACKGROUND
Critically ill patients may show significant weight change in their course of disease during ICU stay. However, what weight changes occur and their effects on patient outcome have not yet been reported to our knowledge. Therefore, we evaluated weight change in critically ill patients in the medical ICU and the effect this may have on clinical outcome.
METHODS
We measured body weight in patients admitted to the medical ICU daily and evaluated their clinical characteristics and outcome.
RESULTS
Thirty-eight patients (M:F = 30:8, mean age = 65.7 +/- 12.5) were enrolled. Thirteen patients (34.2%) showed weight gain and the mean change was 12.8 +/- 4.2%. In contrast, 25 patients (65.8%) showed weight loss and the mean change was 6.3 +/- 6.9%. Patients who showed weight change over 5% or 10% were 26 (68.4%), and 12 (31.6%), respectively, and their mortality rates were 61.5% and 75%, respectively, showing no statistical significance (p > 0.05). However, when the degree of weight change was stratified with < 5%, 5-10% and > 10%, it was associated with death (p = 0.002). Factors like ICU stay, day of mechanical ventilation, initial APACHE II and SOFA score, body mass index (BMI) and serum albumin were not associated with more than 5% change of weight. BMI at admission was only associated with > 10% change of weight (p < 0.05).
CONCLUSIONS
The majority of critically ill patients showed a significant weight change during their ICU stay and these patients may have a tendency to have worse clinical outcome.

Abstract PDF

Muscle wasting is commonly seen in patients with sepsis as a consequence of the catabolic response in skeletal muscle. Muscle wasting can occur in cases that have an imbalance between degradation and synthesis of muscle proteins. Although decrements in the synthesis of muscle proteins may contribute to sepsis-induced muscle wasting, it has been recognized that increments in its degradation play a more essential role in muscle wasting. Muscle wasting in sepsis patients has some significant clinical consequences such as reduced ambulation and exercise tolerance, and an increased risk for pulmonary and thromboembolic complications. Several mechanisms have been proposed for sepsis-induced muscle wasting. Increased proteolysis via the ubiquitin-proteasome pathway and the calpains system is one of the principal mechanisms of muscle wasting induced by sepsis. Calpains are activated by calcium, which increases in patients with sepsis. The activation of the calpains system disrupts the sarcomere of the myofibrils, resulting in the release of myofilaments that are subsequently ubiquitinated and degraded by the 26S proteasome complex. Recent studies have suggested that transcriptional factors such as NF-kappaB and FoxO, and the apoptosis and autophagy-lysosome pathways may also be involved in sepsis-induced muscle wasting. This review briefly summarizes the contribution of these mechanisms of muscle wasting in patients with sepsis and the possible therapeutic agents to treat it.

Abstract PDF

BACKGROUND
To reduce production of resistant bacteria by over-use of antibiotics, an antibiotics restriction policy became effective in several hospitals. However, there are different views on its effect. This study aims to examine antibiotic resistance of pathogenic organisms cultured in tracheal aspirates of the patients who need to maintain mechanical ventilation in medical intensive care unit before and after the antibiotics restriction policy.
METHODS
Before and after 2 years from August 2003, when carried out the antibiotics restriction policy in Gyeongsang university hospital, it was retrospectively investigated the antibiotic resistance pattern of bacteria cultured in tracheal aspirates of the patient who is maintained by mechanical ventilation more than 48 hours in the medical intensive care unit. Restricted antibiotics are ceftazidime, piperacillin/tazobactam, imipenem, meropenem, vancomycin, and teicoplanin.
RESULTS
Before the antibiotics restriction policy, (Sep 2001~Aug 2003) and after, (Sep 2003~Aug 2005), there were 306 and 565 patients applied in each case and the total use of antibiotics, except piperacillin/tazobactam, was reduced and that of cefotaxime and ceftriaxone was increased. There was no significant change in antibiotic resistance among Acinetobacter, Pseudomonas, and Enterobacter species.
CONCLUSION
The result of this study shows that the antibiotics restriction policy does not reduce production of antibiotic resistant bacteria in tracheal aspirate in a medical intensive care unit. However, it is considered that long-term observation may be necessary.

Abstract PDF: BACKGROUND
Microcirculatory derangement in sepsis plays a crucial role in the impairment of tissue oxygenation that can lead to multi-organ failure and death. The change of RBC rheology in sepsis has been known to be important factors in microcirculatory derangement. Several studies have demonstrated that RBCs have decreased deformability in sepsis. We investigated the relationship between multi-organ failure and spherical index of RBC estimated by flow cytometer in critically ill patients with or without sepsis compared with the relationship in healthy volunteers.
METHODS
Fourteen non-septic critically ill patients, 18 septic patients and 10 healthy volunteers were evaluated. We obtained peripheral venous blood from each patient and analyzed the change of RBC shape using flow cytometer (Becton Dickinson FACSCalibur) within 90 minute. The change of RBC shape was accessed with spherical index (M2/M1). A decrease in M2/M1 was correlated with the sphericity of the RBC and considered to have a lower capacity to alter their shape when placed in microcirculation. Multi-organ failure was accessed with sequential organ failure assessment (SOFA) score. RESULTS: The M2/M1 ratio of healthy volunteers, non-septic patients and septic patients were 2.25+/-0.08, 2.16+/-0.39 and 2.05+/-0.53, respectively. But, there was no significant difference between each group (p>0.05). And, there was no significant correlation between M2/M1 ratio of septic and non- septic patients and SOFA score (p>0.05, r2= -0.13). CONCLUSIONS: In our study, the spherical index of RBC was not associated with multi-organ failure in sepsis. But, further studies may be needed to evaluate the role of RBC rheology in sepsis.
