Objective: To compare the clinical effects of rescuing patients with sudden cardiac death between traditional cardiopulmonary resuscitation (CPR) and CPR through pulling and pressing the abdomen.Methods: 48 cases of sudden cardiac death were randomly divided into traditional CPR group (pressing the 1/3 under the sternum) and CPR through pulling and pressing the abdomen group (CPR using abdominal pulling and pressing CPR device), 24 cases each group. The clinical effects and complications of two CPR methods are compared in the recovery process.Results: The CPR group through pulling and pressing the abdomen is significantly better than the traditional CPR group in enhancement of coronary perfusion pressure after CPR, the number of cases of spontaneous breathing recovery, and 24 hours survival rate after recovery, and the incidence of related CPR complications was lower than that of the traditional CPR group（P＜0.05）.Conclusion: CPR by using orotracheal intubation combined with abdominal CPR compression-decompression instrument can significantly improve the coronary perfusion and the success rate of CPR, and significantly reduce the complications in the process of CPR.
