目的基于序贯性持续气囊—面罩通气探讨按压频率对心肺复苏抢救成功率的影响。方法收集2013年6月-2014年6月来该院急诊抢救的心脏骤停患者256例作为试验组,给予100~120次/min按压频率,2009年6月-2010年6月心脏骤停患者156例为对照组,给予80~100次/min按压频率,2组患者均选择序贯性持续气囊—面罩通气,观察2组抢救成功率。结果试验组患者抢救成功率明显高于对照组,死亡率低于对照组,试验组抢救成功患者呼吸恢复时间、心跳恢复时间和意识改善时间均短于对照组,差异均有统计学意义(P<0.05)。结论基于序贯性持续气囊—面罩通气,采用100~120次/分按压频率具有较高的心肺复苏抢救成功率。
Objective To investigate the effect of compression frequency on success rate of cardiopulmonary resuscitation based on sequential continuous balloon-mask ventilation. Methods 256 patients with sudden cardiac arrest from June 2013 to June 2014 in our hospital were recruited as the experimental group and were given 100 ~ 120 times / min compression frequency. June 2009-June 2010 patients with cardiac arrest 156 cases as the control group, given 80 ~ 100 times / min compression frequency, 2 patients were selected sequential sustained balloon - mask ventilation, the success rate of 2 groups were observed. Results The success rate of rescue in trial group was significantly higher than that in control group, and the mortality rate was lower than that in control group. The resuscitation time, heart recovery time and consciousness improvement time in successful rescue group were shorter than those in control group (P <0.05). Conclusions Based on the sequential continuous balloon-mask ventilation, the success rate of resuscitation with CPR between 100 and 120 beats per minute is high.
