摘要
目的分析老年患者冠状动脉搭桥术(coronary artery bypass grafting,CABG)后早期发生低氧血症的危险因素。方法回顾性分析55例老年患者行CABG的病历资料,分析术后72h内发生低氧血症的危险因素。结果 23例(41.82%)老年患者术后72h内发生低氧血症;与未发生低氧血症的老年患者比较,术前肺部疾病或其他原因引起的胸片异常、体外循环时间以及手术时间、术中失血量差异有统计学意义(P<0.05)。结论对术前有肺部疾患或患有影响呼吸功能其他疾病、体外循环时间和手术时间长、术中失血量较大的患者,要早期预见低氧血症发生的可能,积极采取相应措施。
Objective To investigate the risk factors of early postoperative anoxemia in elderly patients after coronary artery bypass grafting(CABG). Methods The risk factors of anoxemia occurred within 72 hours after CABG were retrospectively analyzed based on 55 cases. Results Twenty-three cases(41.82%) suffered from postoperative anoxemia within 72 h after CABG. The risk factors were primary pulmonary diseases or chest X-ray abnormalities caused by other reasons,the duration of extracorporeal circulation and operation,intraoperative blood loss(P〈0.05). Conclusion In order to reduce the incidence of postoperative anoxemia,preventive measures should be taken in elderly patients with primary pulmonary diseases or suffering from other respiratory diseases,long duration of extracorporeal circulation and operation and large intraoperative blood loss.
