Abstract PDF: Background
Coronavirus disease 2019 (COVID-19) patients with acute respiratory failure who experience delayed initiation of invasive mechanical ventilation have poor outcomes. The lack of objective measures to define the timing of intubation is an area of concern. We investigated the effect of timing of intubation based on respiratory rate-oxygenation (ROX) index on the outcomes of COVID-19 pneumonia. Methods: This was a retrospective cross-sectional study performed in a tertiary care teaching hospital in Kerala, India. Patients with COVID-19 pneumonia who were intubated were grouped into early intubation (within 12 hours of ROX index <4.88) or delayed intubation (12 hours or more hours after ROX <4.88). Results: A total of 58 patients was included in the study after exclusions. Among them, 20 patients were intubated early, and 38 patients were intubated 12 hours after ROX index <4.88. The mean age of the study population was 57±14 years, and 55.0% of the patients were male; diabetes mellitus (48.3%) and hypertension (50.0%) were the most common comorbidities. The early intubation group had 88.2% successful extubation, while only 11.8% of the delayed group had successful extubation (P<0.001). Survival was also significantly more frequent in the early intubation group. Conclusions: Early intubation within 12 hours of ROX index <4.88 was associated with improved extubation and survival in patients with COVID-19 pneumonia.

Background
Prediction of intensive care unit (ICU) mortality in traumatic brain injury (TBI), which is a common cause of death in children and young adults, is important for injury management. Neuroinflammation is responsible for both primary and secondary brain injury, and C-reactive protein-albumin ratio (CAR) has allowed use of biomarkers such as procalcitonin (PCT) in predicting mortality. Here, we compared the performance of CAR and PCT in predicting ICU mortality in TBI.
Methods
Adults with TBI were enrolled in our study. The medical records of 82 isolated TBI patients were reviewed retrospectively.
Results
The mean patient age was 49.0 ± 22.69 years; 59 of all patients (72%) were discharged, and 23 (28%) died. There was a statistically significant difference between PCT and CAR values according to mortality (P<0.05). The area under the curve (AUC) was 0.646 with 0.071 standard error for PCT and 0.642 with 0.066 standard error for CAR. The PCT showed a similar AUC of the receiver operating characteristic to CAR.
Conclusions
This study shows that CAR and PCT are usable biomarkers to predict ICU mortality in TBI. When the determined cut-off values are used to predict the course of the disease, the CAR and PCT biomarkers will provide more effective information for treatment planning and for preparation of the family for the treatment process and to manage their outcome expectations.

Abstract PDF

In cardiac arrest, if the initial rhythm is ventricular fibrillation (VF) or pulseless ventricular tachycardia, the survival rates are high and good neurologic outcomes are expected. However, the mortality rate increases when refractory ventricular fibrillation (RVF) occurs. We report a case of RVF that was successfully resuscitated with double sequence defibrillation (DSD). A 51-year-old man visited the emergency department with chest pain. The initial electrocardiography showed markedly elevated ST-segment on V1–V5 leads, and VF arrest occurred. Although 10 defibrillations were administered over 20 minutes, there was no response. Two rounds of DSD were performed by placing additional pads on the patient’s anterior-posterior areas and sequentially applying the maximum energy setting. The patient returned to spontaneous circulation and was discharged with cerebral performance category 1 after 14 days of hospital admission. Therefore, DSD could be an option for treatment and termination of RVF.

Abstract PDF

Background
This study assessed the association between the initial Acute Physiology and Chronic Health Evaluation (APACHE) II score and good neurological outcome in comatose survivors of out-of-hospital cardiac arrest who received targeted temperature management (TTM).
Methods
Data from survivors of cardiac arrest who received TTM between January 2011 and June 2016 were retrospectively analyzed. The initial APACHE II score was determined using the data immediately collected after return of spontaneous circulation rather than within 24 hours after being admitted to the intensive care unit. Good neurological outcome, defined as Cerebral Performance Category 1 or 2 on day 28, was the primary outcome of this study.
Results
Among 143 survivors of cardiac arrest who received TTM, 62 (43.4%) survived, and 34 (23.8%) exhibited good neurological outcome on day 28. The initial APACHE II score was significantly lower in the patients with good neurological outcome than in those with poor neurological outcome (23.71 ± 4.39 vs. 27.62 ± 6.16, P = 0.001). The predictive ability of the initial APACHE II score for good neurological outcome, assessed using the area under the receiver operating characteristic curve, was 0.697 (95% confidence interval [CI], 0.599 to 0.795; P = 0.001). The initial APACHE II score was associated with good neurological outcome after adjusting for confounders (odds ratio, 0.878; 95% CI, 0.792 to 0.974; P = 0.014).
Conclusions
In the present study, the APACHE II score calculated in the immediate post-cardiac arrest period was associated with good neurological outcome. The initial APACHE II score might be useful for early identification of good neurological outcome.

Abstract PDF

Background
To ensure patient safety and improvements in the quality of hospital care, rapid response teams (RRTs) have been implemented in many countries, including Korea. The goal of an RRT is early identification and response to clinical deterioration in patients. However, there are differences in RRT systems among hospitals and limited data are available.
Methods
In Seoul St. Mary’s Hospital, the St. Mary’s Advanced Life Support Team was implemented in June 2013. We retrospectively reviewed the RRT activation records of 287 cases from June 2013 to December 2016.
Results
The median response time and median modified early warning score were 8.6 minutes (interquartile range, 5.6 to 11.6 minutes) and 5.0 points (interquartile range, 4.0 to 7.0 points), respectively. Residents (35.8%) and nurses (59.1%) were the main activators of the RRT. Interestingly, postoperative patients account for a large percentage of the RRT activation cases (69.3%). The survival rate was 83.6% and survival was mainly associated with malignancy, Acute Physiology and Chronic Health Evaluation-II score, and the time from admission to RRT activation. RRT activation with screening showed a better outcome compared to activation via a phone call in terms of the intensive care unit admission rate and length of hospital stay after RRT activation.
Conclusions
Malignancy was the most important factor related to survival. In addition, RRT activation with patient screening showed a better outcome compared to activation via a phone call. Further studies are needed to determine the effective screening criteria and improve the quality of the RRT system.

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: BACKGROUND
Chronic total occlusion (CTO) has been considered as an unsuitable lesion for percutaneous coronary intervention (PCI) because of technical difficulty and low success rate. Owing to technical advances and increased operator's experience, PCI has been attempted in a large number of patients with CTO in recent years, but there are few long-term follow-up reports for PCI to CTO. METHODS: We analyzed 83 patients (59.7+/-9.2 years, 28 female) with CTO on diagnostic coronary angiogram at the Heart Center and Coronary Care Unit of Chonnam National Hospital from January 1996 to July 1997. The patients were divided into two groups according to revascularization by PCI or CABG (coronary artery bypass graft): the revascularized group (received PCI or CABG, Group I) and non-revascularized group (Group II).
RESULTS
PCI was tried in 46 patients and successful in 33 patients (71.7% of the success rate). Eleven patients (13.3%) were treated with the coronary artery bypass graft (CABG) and 31 (37.3%) patients were medically treated. During 5-year clinical follow-up 11 patients died [13.1%; cardiac death 6 (7.1%), non-cardiac death 5 (6.0%)] and the major adverse cardiac events occurred to 24 (28.6%) patients. Cardiac death occurred to one patient of the Group I and 5 patients of Group II (p=0.06). The mean survival time was significantly different (57.8+/-9.2 months in Group I and 50.9+/-19.5 months in Group II, p=0.038). CONCLUSIONS: Revascularization for CTO prolonged the mean survival time of the patients on long- term clinical follow-up.

Abstract PDF: BACKGROUND
Recently the incidence of coronary artery disease has been increased rapidly in Korea. After the introduction of coronary care unit, the mortality rate of cardiovascular patients has been decreased. The predictive factors for mortality in patients admitted at Coronary Care Unit (CCU) are important in the management of acutely ill cardiovascular patients. METHODS: One thousand one hundred and thirty patients (64.8+/-14.5 years), who were admitted at CCU from January 2002 to June 2003, were analyzed. The patients were divided into two groups according to mortality: the survived group (Group I: n=1055, 63.3+/-13.3 years) and the moribund group (Group II: n=75, 64.8+/-14.1 years). Clinical characteristics, risk factors, clinical diagnosis, laboratory, echocardiographic and coronary angiographic findings were compared between the two groups.
RESULTS
The overall mortality at CCU was 6.6%, 75 out of 1130 patients. Age and sex were not different between both groups. Coronary artery disease was the most common cause of admission (886 out of 1130 patients) and death (46 out of 75 patients). Coronary angiographic findings were not different between the two groups. Left ventricular ejection fraction (LVEF) by echocardiogram was higher in Group I than in Group II (53.1+/-15.6% vs. 42.3+/-16.3%, p<0.05). Predictive factors for mortality by multiple logistic regression analysis were low LVEF (OR 11.4, 2.9-21.4 95%CI, p<0.001), no performance of percutaneous coronary intervention (PCI, OR 10.8, 2.5-17.8 95%CI, p<0.001) and clinical diagnosis of aortic dissection (OR 3.8, 1.3-9.8 95%CI, p=0.021).
CONCLUSIONS
The predictive factors for mortality at CCU were low LVEF, no PCI and aortic dissection.
