目的:探讨院内心脏骤停的病人在行标准心肺复苏术(CPR)的同时附加气囊压腹法对提高复苏成功率的影响。方法:ICU内发生的心脏骤停病人96例随机分为气囊压腹法-CPR组(即实验组,n=46例)和标准CPR组(即对照组,n=50例)。对照组按照ABC程序紧急行标准心肺复苏术,实验组在行标准CPR之前通过气囊压住腹主动脉,按压力度150～200mmHg阻断腹主动脉血流。两组均监测有创动脉压及右房压。结果:实验组自主循环恢复率为78.3%,对照组为52.0%(P<0.01);24h自主循环恢复率分别为60.9%和40.0%(P<0.05);实验组冠脉最高灌注压为(26.5±4.3)mmHg,对照组为(12.7±1.7)mmHg(P<0.01)。结论:气囊压腹法-CPR可明显地提高冠脉灌注压,增加自主循环恢复率和24h自主循环恢复率,未发现明显并发症。
Objective: To investigate the effect of balloon compression on the success rate of resuscitation in patients undergoing cardiac arrest in hospital while performing standard cardiopulmonary resuscitation (CPR). Methods: Ninety-six patients with cardiac arrest within ICU were randomly divided into balloon compression-CPR group (n = 46) and standard CPR group (n = 50). Control group according to ABC procedure emergency standard CPR, the experimental group before the standard CPR balloon compression abdominal aorta, pressing intensity 150 ~ 200mmHg blocking the abdominal aorta blood flow. Both groups monitored invasive arterial pressure and right atrial pressure. Results: The recovery rate of spontaneous circulation was 78.3% in the experimental group and 52.0% in the control group (P <0.01), and the recovery rate of spontaneous circulation 24h was 60.9% and 40.0% (P <0.05) 26.5 ± 4.3) mmHg in the control group and (12.7 ± 1.7) mmHg in the control group (P <0.01). CONCLUSION: CPR can significantly improve the perfusion pressure of coronary artery, increase the recovery rate of spontaneous circulation and recovery rate of spontaneous circulation 24h, and no obvious complication has been found.
