Thumper心肺复苏机在院内心脏骤停心肺复苏中的应用

Application of Thumper-1007 CPR system in treatment of in-hospital sudden cardiac arrest： comparison between Thumper system and standard cardiopulmonary resuscitation

目的探讨Thumper-1007型心肺复苏机在抢救院内心脏骤停患者的应用价值。方法回顾性分析73例应用Thumper-1007型心肺复苏机（Thumper组）和58例应用标准CPR（SCPR组）抢救的院内心脏骤停患者的临床资料，比较2组患者的恢复自主循环（ROSC）、ROSC所需时间以及生存出院率。结果Thumper组ROSC显著高于SCPR组（P〈0．05），复苏时间〈30min时，Thumper组ROSC比例显著高于SCPR组（P〈0．05），ROSC所需时间Thumper组优于SCPR组（P〈0．05）。2组生存出院率无显著性差异。结论对于院内心脏骤停患者，Thumper心肺复苏机复苏效率优于标准CPR。

Objective To compare the therapeutic effects between the Thumper CPR system, an automatic machine providing chest compression synchronized with intermittent positive pressure ventilation with a compression/ventilation ratio of 5：1, and standard CPR （SCPR） in treatment of in-hospital sudden cardiac arrest（SCA）. Methods Fifty-eight patients with cardiopulmonary arrest （CPA）, 37 males and 21 females, aged （60±18.5）, were treated with SCPR in the Intensive Care Unit （ICU） during the period February-December 2007. Another 73 CPA patients, 43 males and 30 females, aged （62.4 ±17.4）, were treated with Thumper-1007 System in ICU during the period March-December 2008. The return of spontaneous circulation （ROSC） time, collapse-to-ROSC interval, and survival/hospital discharge rates were compared between the two groups. Results There were not significant differences in the age and etiology of CPA between these 2 groups. The ROSC rate of the Thumper Group was 53.4%, significantly higher than that of the SCPR group （40.7%, P〈0.05）. There were not significant differences in the time needed for ROSC and survival/discharge rate between these 2 groups. When the collapse-to-ROSC interval was 〈30 min, 31 patients of the Thumper Group reached ROSC, a number significantly higher than that of the SCVPR group （23 cases, P〈0.05）, and the collapse-to-ROSC interval of the Thumper group was （6.9±9.5） min, significantly shorter than that of the SCPR group [（9 . 1 ±7.8） min, P〈0.05]. Ten patients of the Thumper group and 3 patients of the SCPR group suffered from cardiogenic sudden death, and there were not significant differences in the case number who got ROSC, ROSC time, and survival rate between these 2 groups （all P 〉0.05）. Conclusion An ideal new type instrument, Thumper CPR system is prior to SCPR in the treatment of in-hospital sudden cardiac arrest.
