目的：探讨高龄（﹥80岁）患者与60~70岁患者围术期并发症发病率是否存在差异。方法回顾性分析接受冠状动脉旁路移植术患者365例的临床资料，其中年龄﹥80岁组52例，60~70岁组313例。观察比较两组术后主要并发症情况，包括：术后二次开胸、术后低心排、脑卒中、呼吸衰竭、术后需透析治疗的肾功能衰竭以及死亡。结果两组术后二次开胸发生率无显著差异（ P ﹥0.05）。﹥80岁组术后低心排（5.8﹪ vs.0）、术后脑卒中（1.9﹪ vs.0.3﹪）、术后呼吸衰竭（7.7﹪ vs.1.0﹪）、术后需透析治疗的肾功能衰竭（3.8﹪ vs.0）、死亡（11.5﹪ vs.1.3﹪）的发生率均高于60~70岁组患者组，差异均有统计学意义（ P ﹤0.05）。结论接受冠状动脉旁路移植术的患者中，年龄﹥80岁者更容易出现术后低心排、术后脑卒中、术后呼吸衰竭、术后需透析治疗的肾功能衰竭及死亡。%Objective To examine whether complication rates among elderly patients ﹥or=80 years undergoing coronary artery bypass grafting( CABG)differed from their younger counterparts 60~70 years. Methods We retrospectively analyzed the results of CABG cases per_formed at our hospital. Perioperative data were collected and compared between patients 60~70 years(n=313)and patients above 80 years of age (n=52). Major postoperative complications were collected,such as:re-exploration for bleeding,postoperative low cardiac output syndrome, postoperative stoke,postoperative respiratory failure,postoperative renal failure requiring hemofiltration and operative mortality. Results The var_iables of re-exploration for bleeding did not significantly differ in analysis( P ﹥0. 05). The variables of postoperative low cardiac output syndrome (5. 8﹪ vs. 0),postoperative stoke(1. 9﹪ vs. 0. 3﹪),postoperative respiratory failure(7. 7﹪ vs. 1. 0﹪),postoperative renal failure requi_ring hemofiltration(3. 8﹪ vs. 0)and postoperative death(1. 4﹪ vs. 1. 3﹪),which were more frequent in elderly patients( P ﹤0. 05). Con-clusion CABG in the elderly patients had postoperative complications such as postoperative low cardiac output syndrome,postoperative stoke, postoperative respiratory failure,postoperative renal failure requiring hemofiltration. The operative mortality more frequent in the octogenarians than in the younger patients.
