心肺复苏仪胸外心脏按压对心肺复苏成功的影响

Influence on Success in Cardiopulmonary Resuscitation at External Cardiac Compress Using Cardiopulmonary Resuscitation Instrument

目的:探讨心肺复苏仪胸外心脏按压对心肺复苏成功的影响。方法:将42例心跳呼吸骤停患者随机分为徒手胸外心脏按压组(A组)和心肺复苏仪胸外心脏按压组(B组)。二组均进行无创动脉血压、心电、经皮氧饱和度sPO2等监测。结果:B组的自主循环恢复率和24小时存活率均明显高于A组(P<0.05和P<0.01),但二组的出院存活率无显著性差异。B组的经皮氧饱和度明显高于A组(P<0.05),而自主循环恢复时间则明显短于后者(P<0.01);二组的平均动脉压无显著性差异。结论:心肺复苏仪胸外心脏按压在提高自主循环率,缩短自主循环恢复时间,改善患者生存机会等方面明显优于徒手胸外心脏按压。

Objective: To investigate the influence on success in cardiopulmonary resuscitation at external cardiac compress using cardiopulmonary resuscitation instrument. Methods: 42 patients with sudden cardiac-respiration arrest were divided into two groups: external cardiac compress using cardiopulmonary resuscitation instrument group(B group) and freehand external cardiac compression group (A group) . In two groups, patient's blood pressure and electrocardiogram and saturation of oxygen from skin (sPO2) were monitored. Results: The rate of spontaneous circulation restoration and survival rate at 24 hour in B group were significantly higher than thai in A group (respectively P < 0.05 or P < 0. 01). The survival rate of leave hospital had no significant difference. sPO2 in B group was significantly higher than that in A group ( P < 0. 05). The average time of spontaneous circulation restoration in B group was significantly lower than that in A group (P < 0.01) . The mean artery blood pressure had no significant difference. Conclusions: External cardiac compress using cardiopulmonary resuscitation instrument has better effects on increasing rate of spontaneous circulation restoration and shorten the average time of spontaneous circulation restoration and improve the chance for survival with cardiac-respiration arrest than freehand external cardiac compression.
