Abstract
<p>So far, there remains a controversy regarding the efficacy of epinephrine (Ep) in patients with cardiopulmonary arrest (CPA). In this study, we evaluated the importance of the plasma levels of catecholamines prior to the administration of Ep in patients with CPA. Patients with out-of-hospital cardiac arrest (OHCA) who were transferred to Gunma University Hospital were enrolled prospectively between July 2014 and July 2017. The levels of catecholamines [Ep, norepinephrine (NEp), and dopamine] and vasopressin (antidiuretic hormone) in the plasma were measured using blood samples of cardiogenic patients with OHCA not treated with Ep. Patients were divided into two groups: the return of spontaneous circulation [ROSC (+) ] group and the no return of spontaneous circulation [ROSC (−) ] group. The plasma levels of these agents and the conditions of resuscitation were compared between these two groups. 48 patients with cardiogenic CPA had not been treated with Ep prior to obtaining the blood samples. The ROSC (+) and ROSC (−) groups included 14 and 34 patients, respectively. The frequency of prehospital defibrillation was significantly higher in the ROSC (+) group. However, the prehospital resuscitation time was significantly shorter in the ROSC (+) group. Moreover, the levels of Ep and NEp in the plasma were significantly lower in the ROSC (+) group. The increased levels of Ep in the plasma may not be associated with the acquisition of ROSC in patients with cardiogenic CPA.</p>
