主动脉内球囊反搏在心脏围手术期的应用

目的 探讨心脏围手术期应用主动脉内球囊反搏（IABP）的疗效。方法 分析2001年1月～2007年8月55例应用IABP心脏手术患者的资料。结果 本组总病死率42%，其中冠心病患者手术死亡率（36%)低于非冠心病者的手术死亡率（64%，P<0.05）；术前应用IABP患者手术死亡率（0%）明显低于术中（40%）和术后（50%）应用IABP的患者（P<0.05）；IABP辅助后血流动力学指标明显改善，血管活性药物用量减少。结论 IABP是救治重症高危心脏病患者的有效手段, 其效果主要取决于患者的心脏病基础情况以及IABP的正确操作和使用的指征和时机。

Perioperative application of intra-aortic balloon pump in cardiac surgery

AIM To discuss the perioperative application of intra-aortic balloon pump (IABP) in high-risk patients undergoing cardiac operations. METHODS From Jan. 2001 to Aug. 2002, 55 patients undergoing cardiac operation with application of IABP perioperatively were analyzed. RESULTS The total mortality was 42%, with 36.4% in coronary heart disease patients and 64% in non-coronary heart disease patients (P<0.05). In patients using IABP preoperatively, the mortality was much lower than that in patients using IABP during or postoperatively (0%, 40%, 50% respectively, P<0.05). After using IABP, homodynamic data improved and dose of cardiovascular drugs decreased significantly. CONCLUSION IABP is a safe and effective mode of circulation support. Prognosis depends on the heart conditions, proper indication, correct set-up and monitoring for IABP.
