Abstract

Background: The use of mechanical cardiopulmonary resuscitation device has been very prevalent in out-of-hospital cardiac arrest rescue. This study aimed to investigate whether the timing of mechanical cardiopulmonary resuscitation device set-up correlated with the the outcome of cardiac arrest patients.

Methods: We retrospectively reviewed adult nontrauma cardiac arrest cases in New Taipei City, Taiwan, from January to December 2022. Demographic data, intervention-related factors, and the time variables of mechanical cardiopulmonary resuscitation were collected. The outcomes included the return of spontaneous circulation and 24-hour survival. We compared patients who achieved spontaneous circulation and those who did not with univariate and multivariable regression analyses.

Results: In total, 1680 patients who received mechanical cardiopulmonary resuscitation were included in the analysis. Reducing the time interval from manual chest compression initiation to device setup was independently associated with the return of spontaneous circulation and 24-hour survival, especially in the subgroup of patients of initial shockable rhythm. Receiver operating characteristic analysis revealed that the outcome of patients with an initial shockable rhythm could be predicted by the mechanical cardiopulmonary resuscitation setup time, with areas under the curve of 60.8% and 63.9% for ROSC and 24-hour survival, respectively. The cutoff point was 395.5 s for patients with an initial shockable rhythm.

Conclusion: A positive correlation was found between early mechanical cardiopulmonary resuscitation intervention and the outcomes of out-of-hospital cardiac arrest patients. The time between manual chest compression and device setup could predict the return of spontaneous circulation and 24-hour survival in the subgroup of patients with initially shockable rhythm with the optimal cutoff point at 395.5 s.

院外心脏骤停患者早期使用院前机械心肺复苏术:一项观察性研究。
背景:在院外心脏骤停抢救中,机械心肺复苏装置的使用非常普遍。本研究旨在探讨机械心肺复苏装置的安装时间是否与心脏骤停患者的预后相关:我们回顾性分析了 2022 年 1 月至 12 月台湾新北市非创伤性成人心脏骤停病例。收集了人口统计学数据、干预相关因素和机械心肺复苏的时间变量。结果包括自发循环恢复和 24 小时存活率。我们通过单变量和多变量回归分析比较了获得自主循环的患者和未获得自主循环的患者:共有 1680 名接受过机械心肺复苏的患者被纳入分析。缩短从开始人工胸外按压到装置安装的时间间隔与自发性循环恢复和 24 小时存活率有独立关系,尤其是在初始可电击心律的亚组患者中。接收器操作特征分析表明,机械心肺复苏装置的设置时间可以预测初始可电击心律患者的预后,ROSC 和 24 小时存活率的曲线下面积分别为 60.8% 和 63.9%。初始可电击心律患者的临界点为 395.5 秒:结论:早期机械心肺复苏干预与院外心脏骤停患者的预后呈正相关。人工胸外按压和装置安装之间的时间可以预测最初有可电击心律的亚组患者的自主循环恢复和24小时存活率,最佳临界点为395.5秒。
