BACKGROUND: The prognostic significance of change in red cell distribution width (RDW) during hospital stays in patients treated with therapeutic hypothermia (TH) after out-of-hospital cardiac arrest (OHCA) was investigated. METHODS: Patients treated with TH after OHCA between January 2009 and August 2013 were reviewed. Patients with return of spontaneous circulation (ROSC) were assessed according to Utstein Style. Hematologic variables including RDW, hematocrit, white blood cell count, and platelets were also obtained. RDW changes during the 72 hours after ROSC were categorized into five groups as follows: Group 1 (-0.8-0.1%), Group 2 (0.2-0.3%), Group 3 (0.4-0.5%), Group 4 (0.6-0.8%), and Group 5 (>0.8%). RESULTS: A total of 218 patients were enrolled in the study. RDW changes during the 72 hours after ROSC in Group 4 (HR 3.56, 95% CI 1.25-10.20) and Group 5 (HR 5.07, 95% CI 1.73-14.89) were associated with a statistically significant difference in one-month mortality. RDW changes were associated with statistically significant differences in neurologic outcome at 6 months after ROSC (Group 3 [HR 2.45, 95% CI 1.17-5.14], Group 4 [HR 2.79, 95% CI 1.33-5.84], Group 5 [HR 3.50, 95% CI 1.35-7.41]). Other significant variables were location of arrest, cause of arrest, serum albumin, and advanced cardiac life support time. CONCLUSIONS: RDW change during the 72 hours after ROSC is a predictor of mortality and neurologic outcome in patients treated with TH after OHCA.

PURPOSE: On November 23, 2010, Yeonpyeong Island was under artillery fire and mass civilian casualties developed. Incheon West-sea regional emergency medical center, dispatched a disaster team to deal with the casualties. The purpose of this study was to review the regional disaster response of this team to improve the operations of the National Disaster Medical System, Disaster Medical Assistance Team, and the Mobile Emergency Support Unit in case of future emergencies. METHODS: We retrospectively reviewed the disaster response upon bombardment of the Yeonpyeong Island and analyzed medical records of patients who treated by the disaster team at Yeonpyeong island. RESULTS: The disaster team and EMS were activated after the bombardment. Disaster team included two doctors, three emergency medical technicians, and one ambulance driver. The bombardment occurred at 14:34, and lasted for 30 minutes. The disaster team was dispatched at 16:40, and arrived in Incheon port at 17:07 and departed for Yeonpyeong Island with a fire engine and ambulance at 21:48. Our team reached the island the next morning and started to treat a patient. A total of 30 patients were participated in this study. The mean age of the patients was 49.4(+/-14.2) yrs old. Most of he patients are a mild case. Diagnosis was multiple contusion, acute stress reaction, cerebral concussion, rupture of tympanic membrane. Also: It may help to include data/analyses showing that there were inadequacies and problems with the system (time lag, insufficient medical training or supplies, etc.) CONCLUSION: This article is the first to report on the efficacy of the National Disaster Medical System after bombardment. From our analysis, the National Disaster Medical System contains many problems including access to the island, the equipment of communication, and the security of disaster team. This report shows that a review of our National Disaster Medical System is necessary to plan for future disaster scenarios.

PURPOSE: The aim of this study is to determine whether cardiac biomarkers, such as N-terminal-proB-type natriuretic peptide (NT-proBNP), are good predictors of adverse events in acute pulmonary embolism (APE). METHODS: We conducted a retrospective analysis of patients with APE, which was confirmed by a computed tomography in the emergency room. Patients were divided into 2 groups: the major adverse event (MAE) group and the no-MAE group. MAE was defined as one of the following occurrences: in-hospital-death, cardiopulmonary resuscitation, mechanical ventilation, vasopressors, thrombolysis, or surgical embolectomy. Blood samples were obtained during the first hour of presentation to the emergency room. RESULTS: A total of 90 patients were included in this study. Twenty-seven patients had MAE. According to the univariate analysis, NT-proBNP, troponin I, and D-dimer plasma levels were significantly higher in the MAE group than in the noMAE group (919.8 vs. 2,131.0 ng/mL, p=0.032; 0.091 vs. 0.172 ng/mL, p=0.037; 2.43 vs. 3.74 ng/mL, p=0.049, respectively). However, according to the multivariate logistic regression, NT-proBNP was not independently associated with MAE in APE (odds ratio, 1.01; 95% confidence interval, 1.00-1.01). Conversely, troponin I was independently associated with MAE (odds ratio, 1.09; 95% confidence interval, 0.99-1.18). The NT-proBNP plasma level was not significantly different between the right ventricular dysfunction (RVD) group and the no-RVD group (p=0.178). CONCLUSION: The NT-proBNP level, unlike the troponin I level, in the emergency room was not identified as an independent predictor of MAE in acute pulmonary embolism. Further studies of large-scale with controlled timing of blood sampling and echocardiography are required.
