第三代心肺复苏机在院外心脏骤停中的效果评价

The effects of the third-generation mechanical chest compressor on outcomes of cardiopulmonary resuscitation in out-of-hospital cardiac arrest： a prospective trial

目的比较第三代心肺复苏机和标准人工按压在院外心脏骤停患者中的复苏效果。方法本研究为前瞻性单中心随机对照实验。研究对象为余姚市人民医院急诊科2015年10月至2017年9月接收的院外心脏骤停患者，转入急诊抢救室后随机分为人工按压组和机械按压组。比较两组间的复苏持续时间、自主循环恢复率、4h生存率及出院时的神经系统恢复率。结果共有95例院外心脏骤停患者符合入组标准，其中机械按压组53例，人工按压组42例。机械按压组的自主循环恢复率、4h生存率明显高于人工按压组（P〈0．05），但两组间的复苏持续时间及出院时神经系统恢复率差异无统计学意义。结论相对于标准徒手胸外按压，第三代心肺复苏机明显改善了院外心脏骤停患者的复苏成功率和短期生存率。

Objective To investigate the effects of the third-generation mechanical chest compressor on outcomes of cardiopulmonary resuscitation in patients with out-of-hospital cardiac arrest. Methods The patients with out-of-hospital cardiac arrest from October 2015 to September 2017 in the Yuyao peoples＇ hospital were included and divided randomly into 2 groups： manual chest compression group and mechanical chest compression group. The duration of resuscitation, the rate of restoration of spontaneous circulation （ROSC）, 4-h survival rate and the rate of survival getting to hospital discharge with favorable neurological status of two groups were analyzed. Results A total of 95 patients with out- of-hospital cardiac arrest were included. The rate of ROSC and 4-h survival was significantly increased in the mechanical chest compression group compared with the manual chest compression group （P〈0.05）. There was no remarkable difference in the duration of resuscitation and the rate of survival getting to hospital discharge with favorable neurological status between 2 groups. Conclusions The thirdgeneration mechanical chest compressor significantly improves the rate of ROSC and the shout-term survival in patients with out-of-hospital cardiac arrest.
