Abstract

Background: This study attempted to correlate the initial cardiac rhythm and survival from prehospital cardiac arrest, as a secondary end-point.

Methods: Prospective, randomized, double-blinded clinical intervention trial where bicarbonate was administered to 874 prehospital cardiopulmonary arrest patients in prehospital urban, suburban, and rural emergency medical service environments.

Results: This group's manifested an overall survival rate of 13.9% (110 of 793) of prehospital cardiac arrest patients. The most common presenting arrhythmia was ventricular fibrillation (VF) (45.0%), asystole (ASY) (34.4%), and pulseless electrical activity (PEA) (15.7%). Less commonly found were normal sinus rhythm (NSR) (1.8%), other (1.8%), ventricular tachycardia (VT) (0.6%), and atrioventricular block (AVB) (0.5%) as prearrest rhythms. The best survival was noted in those with a presenting rhythm of AVB (57.1%), VT (33.3%), VF (15.7%), NSR (14.3%), PEA (11.2%), and ASY (11.1%) (p = 0.02). However, there was no correlation between the final cardiac rhythm and outcome, other than an obvious end-of-life rhythm.

Conclusion: The most common presenting arrhythmia was VF (45%), while survival is greatest in those presenting with AVB (57.1%).

初始心律与急诊存活率相关。

背景：本研究试图将初始心律与院前心脏骤停的存活率作为次要终点进行关联。方法：前瞻性、随机、双盲临床干预试验，对874名院前城市、郊区和农村急救医疗服务环境中的院前心肺骤停患者施用碳酸氢盐。结果：该组的院前心脏骤停患者的总生存率为13.9%（110/793）。最常见的心律失常表现为心室颤动（VF）（45.0%）、心搏停止（ASY）（34.4%）和无脉冲电活动（PEA）（15.7%）。不常见的心律是正常窦性心律（NSR）（1.8%）、其他心律（1.8%），室性心动过速（VT）（0.6%）和房室传导阻滞（AVB）（0.5%）。存活率最高的是出现AVB（57.1%）、VT（33.3%）、VF（15.7%）、NSR（14.3%）、PEA（11.2%）和ASY（11.1%）节律的患者（p=0.02）。然而，除了明显的临终节律外，最终心律与结果之间没有相关性。结论：最常见的心律失常表现为VF（45%），而AVB患者的存活率最高（57.1%）。
