Out-of-hospital cardiac arrest (OHCA) due to drowning carries high morbidity and mortality. There are a few studies on drowning-related out-of-hospital cardiac arrest (OHCA), in which patients are followed from the scene to hospital discharge. This study aims to compare patient characteristics between the survival group and mortality group of OHCA due to drowning. OHCA due to drowning cases were selected from the North America Termination of Resuscitation Association database between 2011 and 2015. The retrospective analysis of epidemiological characteristics and clinical features of all OHCA patients were performed. Of the 17,094 OHCA cases in the registry, 54 cases of OHCA due to drowning were included in this study. Among the 54 OHCAs due to drowning, 7 (13.0%) survived, while 47 (87.0%) died. Compared to the mortality group, the survival group had a higher bystander witness rate (57.1% versus 17.0%, < 0.05), higher asystole rate (42.9% versus 78.7%, < 0.05), and higher mild therapeutic hypothermia rate (28.6% versus 2.1%, < 0.05). In addition, a large proportion of survivors were children (71.4%) and males (71.4%). Survival among OHCA's due to drowning was found to be improved with a higher bystander rate, higher asystole rate, and higher mild hypothermia rate. In addition, children and males comprised the majority of survivors.
溺水导致的院外心脏骤停（OHCA）具有很高的发病率和死亡率。关于与溺水相关的院外心脏骤停（OHCA）的研究较少，这些研究对患者从现场到出院进行随访。本研究旨在比较溺水导致的院外心脏骤停患者生存组和死亡组之间的患者特征。从北美复苏终止协会数据库中选取2011年至2015年期间溺水导致的院外心脏骤停病例。对所有院外心脏骤停患者的流行病学特征和临床特征进行回顾性分析。登记的17094例院外心脏骤停病例中，本研究纳入了54例溺水导致的院外心脏骤停病例。在这54例溺水导致的院外心脏骤停病例中，7例（13.0%）存活，47例（87.0%）死亡。与死亡组相比，生存组的旁观者目击率更高（57.1%对17.0%，<0.05），心搏停止率更高（42.9%对78.7%，<0.05），轻度治疗性低温发生率更高（28.6%对2.1%，<0.05）。此外，很大一部分幸存者是儿童（71.4%）和男性（71.4%）。研究发现，溺水导致的院外心脏骤停患者中，较高的旁观者率、较高的心搏停止率和较高的轻度低温发生率可提高生存率。此外，儿童和男性占幸存者的大多数。
