The Effect of Epinephrine Administration on Return of Spontaneous Circulation and One-Month Mortality with Cardiopulmonary Arrest Patients
EUROPEAN JOURNAL OF THERAPEUTICS(2020)
Abstract
Objective: The objective of this study is to determine the effect of epinephrine administration on the return of spontaneous circulation (ROSC) and one-month mortality in patients with cardiopulmonary arrest. Methods: We conducted this study between August 1, 2016 and May 31, 2017. Importantly, we included the witnessed cases (>= 18 years) of in-emergency department cardiopulmonary arrest (IEDCA) and out-of-hospital cardiopulmonary arrest (OHCA) in the study. We divided the patients into two groups: the adrenaline group (Group 1) and the non-adrenaline group (Group 2). Thereafter, we investigated ROSC and one-month mortality in them. Results: We included 183 patients (50.3% of males and 49.7% of females with a mean age of 64.2 +/- 16.8 years) in the study. The percentages of IEDCA and OHCA cases were 25.1% and 74.9%, respectively. Epinephrine was administered to 100 (54.6%) patients (Group 1). Among these patients, 15.9% (n=29) of the patients had shockable rhythms (ventricular fibrillation, pulseless ventricular tachycardia) and 84.1% (n=154) of them had non-shockable rhythms (asystole, pulseless electrical activity) as the initial rhythm. ROSC and one-month mortality rate of these patients were 24% (n=44) and 72.8% (n=36), respectively. The one-month mortality rates of Group 1 (30% of patients had IEDCA and 70% of patients had OHCA) and Group 2 were 43.8% and 56.2%, respectively (p=0.0231). The ROSC and one-month mortality rates of Group 1 and Group 2 cases, whose initial rhythm was a shockable rhythm, were 26.6% and 50% vs. 42.8% and 66.6%, respectively. Conclusion: In this study, we found no significant difference in terms of obtaining ROSC between the shockable rhythm and ROSC in the IEDCA and OHCA cases (p=0.963 and p=0.141, respectively). The effect of epinephrine administration on patients with IEDCA and OHCA whose ROSC was obtained on one-month mortality was not statistically significant (p>0.05).
