IABP在危重症冠状动脉旁路移植术围手术期的应用

目的:探讨危重症冠状动脉旁路移植术(CABG)患者围手术期应用主动脉球囊反搏(IABP)疗效。方法:回顾性分析2008年1月至2010年9月40例应用IABP治疗的危重症CABG患者围手术期资料。结果:术前安置IABP 19例,术中安置IABP 10例,术后安置IABP11例。平均IABP辅助时间98.6±48.2小时。32例患者治愈出院,死亡8例,死亡率20.0%。术前安置者死亡率为21.1%,若除外机械并发症原因则死亡率为10.5%;术中安置者死亡率为20.0%;术后安置者死亡率为18.2%。5例出现血小板减少症;1例出现肠系膜动脉栓塞。结论:IABP是一种安全有效的循环辅助方法,积极应用可以明显提高危重症CABG的治疗效果。

Perioperative Application of the Intra-aortic Balloon Pump in High-risk Patients Undergoing Coronary Artery Bypass Grafting

Objective: To evaluate effect of the perioperative application of intra-aortic balloon pump (IABP) in high-risk patients undergoing coronary artery bypass grafting (CABG). Methods: From Jan 2008 to Sep 2010, the data of 40 high-risk patients undergoing CABG with application of IABP were analyzed retrospectively. Results: IABP was applied for 19, 10 and 11 cases at pre, intra and post operative period respectively. The total mortality was 20.0 %. The mortality of application of IABP at pre, intra and post operative period were 21.1 %, 20.0 % and 18.2 % respectively. However, if the ventricular septal rupture was excluded, the mortality of application of IABP at pre-operative period was only 10.5%. Conclusions: IABP is a safe and effective mode for circulation support. The appropriate and enthusiastic application of IABP perioperatively can improve effect in high-risk patients undergoing CABG.
