RESUMO
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.
