急诊心肺复苏时间窗与复苏成功率和心功能恢复情况的相关性分析

Correlation analysis of time window and success rate of resuscitation and cardiac function recovery in emergency patients

目的研究分析急诊心肺复苏时间窗与复苏成功率和心功能恢复情况的相关性。方法2013年1月至2016年12月期间收治的急诊心肺复苏患者92例,整理分析复苏时间、复苏效果、复苏成功后心功能等资料,分析比较急诊心肺复苏时间窗与复苏成功率和心功能之间的关系。结果不同急诊心肺复苏时间复苏成功率差异具有统计学意义(P<0.05),且心肺复苏时间<3 min组>心肺复苏时间3~8 min组>心肺复苏时间>8 min组(P<0.05);不同急诊心肺复苏时间分组心功能指标舒张早期充盈峰速度(E峰)、左心室舒张末期直径(Left ventricular end diastolic diameter,LVEDD)和射血分数(Left Ventricular Ejection Fractions,LVEF)结果也显示患者心功能心肺复苏时间(<3 min)组>心肺复苏时间(3~8 min)组>心肺复苏时间(>8 min)组(P<0.05)。单因素回归分析结果表明心肺复苏时间与心肺复苏成功率呈负相关(决定系数r2=0.698),与超声心功能指标E峰、LVEDD、LVEF也成负相关(P<0.05)。结论缩短急诊心肺复苏时间窗能够提高复苏成功率,促进心功能恢复。

Objective To study the correlation between the time window and the success rate of resuscitation and the recovery of cardiac function in emergency cardiopulmonary resuscitation （CPR）. Methods From January, 2013 to December, 2016, 92 patients with emergency cardiopulmonary resuscitation were collected. The data of recovery time, recovery effect and cardiac function after successful resuscitation were analyzed and compared. The relation between CPR time window and recovery success rate and cardiac function was analyzed and compared.Results There was significant difference in the success rate of different emergency cardiopulmonary resuscitation （ P 〈 0. 05 ）, cardiopulmonary resuscitation time 〈 3min group 〉 cardiopu｜monary resuscitation time group 3- 8rain 〉 cardiopulmonary resuscitation time group 〉8min （P〈0.05） ; Cardiopulmonary resuscitation time group heart function indexes of different emergency early diastolic peak velocity （ E peak ） , LVEDD and LVEF. The results also showed that the time of cardiopulmonary resuscitation （ 〈 3min） in the patients with cardiopulmonary resuscitation （ 3 - 8rain ） group （ 〉 8rain ） group （ P 〈 0. 05 ）. Emergency cardiopulmonary resuscitation time as a single factor regression analysis, The results showed that the cardiopulmonary resuscitation time was negatively correlated with the success rate of cardiopulmonary resuscitation （r2= 0. 698 ）, E, LVEDD and LVEF were also negatively correlated with echocardiography （P 〈 0. 05 ）. Conclusions Shortening the time window of emergency cardiopulmonary resuscitation can improve the success rate of resuscitation and promote the recovery of cardiac function.
