高龄患者非体外循环和体外循环冠状动脉旁路移植术的早期结果分析

摘要

目的 探讨≥80岁的高龄患者非体外循环冠状动脉旁路移植手术(OPCABG)相对传统体外循环冠状动脉旁路移植手术(CCABG)的早期疗效. 方法 选择≥80岁进行CABG患者105例,根据手术方式不同,分为CCABG组(60例)和OPCABG(45例),对两组的临床资料进行回顾性分析. 结果 OPCABG组术后30 d病死率低于CCABG组(5.0％和8.3％,P＜0.05),与CCABG组相比较,OPCABG组ICU时间[(37.1±30.3)h和(60.6±58.2) h],呼吸机辅助时间[(10.8±9.7)h和(22.3±35.7) h],输血量[(845±151)ml和(1160±1052) ml],神经系统并发症(0.0％和3.3％),术后房颤发生率(31.1％和41.7％)均低于CCABG组(均P＜0.05). 结论 OPCABG在≥80岁高龄患者中能够取得良好的临床效果,对于高龄患者如果可能的话,应尽量考虑采用OPCAB.%Objective To compare the outcomes of off-pump versus on-pump CABG.Methods From 2002 to 2008,CABG was performed in 105 patients aged 80 years and over,including 45 without cardiopulmonary bypass (CPB) or off-pump (OP) CABG (OPCAB) and 60 with CPB (onpump CABG).The outcomes were compared between two groups.Results The mean ICU stay was (37.1±30.3) h in OPCAB group and (60.6±58.2) h in on-pump CABG group (P＜0.01).Average ventilator-assisted time was (10.8±9.7) h for OPCAB group versus (22.3±35.7) h for onpump CABG group (P＜0.01).Postoperative atrial fibrillation occurred in 31.1％ of OPCABG patients and 41.7 ％ of on-pump CABG patients (P＜0.01).The mortality rate was 5.0％ in OPCABG group versus 8.3％ in on-pump CABG group (P＜0.05).Conclusions OPCABG is a safe and efficient method of myocardial revascularization in the elderly patients with lower morbidity and complications.
