- Purpose: We investigated the association between defoliant exposure and survival to discharge after out-of-hospital cardiac arrest. Methods: This is a retrospective case-control study based on the cardiopulmonary resuscitation (CPR) registry. The electronic medical records of out-of-hospital cardiac arrest victims from 6/9/2008 to 12/31/2016 were analyzed statistically. The case patients group had a history of defoliant exposure while the control group did not. Among the 401 victims studied, a total of 110 patients were male out-of-hospital cardiac arrest patients. Baseline characteristics and the parameters involved in cardiac arrest were analyzed and compared between the two groups after propensity score matching. The primary outcome was survival to discharge, and secondary outcomes were sustained return of spontaneous circulation (ROSC) and survival to admission. Results: After propensity score matching a total of 50 patients (case=25, control=25) were analyzed. Primary outcome (survival to discharge) was not significantly different between case and control groups [(OR, 1.759; 95% C.I., 0.491-6.309) and (OR, 1.842; 95% C.I., 0.515-6.593), respectively]. In the subgroup analysis, there were also no significant differences between the control group and subgroups in primary and secondary outcomes according to defoliant exposure severity. Conclusion: There is no statistically significant association between defoliant exposure and survival of out-of-hospital cardiac arrest.

- Purpose: This study was to investigate the resuscitation outcomes and the clinical characteristics of non-traumatic drug-induced out-of-hospital cardiac arrest by analyzing data from a single institution's registry. Method: We conducted a retrospective study of 795 patients who came to the emergency department with non-traumatic drug-induced out-of-hospital cardiac arrest during the period $1991{~}2004$. Only patients over 18 years of age were included. Clinical characteristics. variables associated with cardiac arrest, and data during resuscitation were obtained from our cardiac arrest database. Patients were divided into two groups: drug-induced cardiac arrest (drug group, n=33), and non drug-induced cardiac arrest (non-drug group, n=762). Results: Spontaneous circulation was restored in 23 ($72{\%}$) patients in the drug group and in 314 ($45{\%}$) patients in the non-drug group ($x^2=0.020$). The patients who discharged alive number were 46 ($6{\%}$) in the non-drug group and 0 ($0{\%}$) in the drug group ($x^2=0.005$). The witnessed arrest, the epinephrine doses, and total defibrillation energy were not different between two groups. Conclusion: The return of spontaneous circulation rate was higher in the drug group than the non-drug group. However the drug group was lower survival discharge rate than in the non-drug group.
