弹力腹带持续腹部加压式心肺复苏时颈总动脉血流变化的研究

Study on Hemodynamics of Arteria Carotis Communis During Elastic Cummerbundstyle Continuous Abdominal Pressure-Cardiopulmonary Resuscitation

目的:观察在进行徒手心肺复苏(CPR)操作时,加用弹力腹带对CPR患者颈总动脉血流量的影响。方法:32例呼吸心跳停止需要实施心肺脑复苏的病人,在非腹部持续加压(A组)和腹部持续加压(B组)两种条件下,应用彩色多普勒超声分别测量按压时颈总动脉的内径和血流速度,并对实验数据进行统计学分析。结果:B组颈总动脉血流量较A组明显增加(P<0.01)。结论:使用弹力腹带持续腹部加压下徒手心肺复苏,可明显增加颈总动脉血流量。

Objective：To observe the change of hemodynamics of arteria carotis communis during elastic cummerbund-style continuous abdominal pressurecardiopulmonary resuscitation （CAP-CPR）. Methods：The CCA, Vmax and blood flow of arteria carotis communis in 32 patients with respiratory and cardiac arrest were detected by CDFI before（group A） and after（group B） using CAP-CPR. The data were statistically analyzed. Results： The blood flow of arteria carotis increased significantly in the group B than that in the group A,P〈0.01. Conclusions： CAP-CPR significantly increase the blood flow of arteria carotis communis.
