冠状动脉搭桥术后呼吸衰竭的预防

目的探讨冠状动脉搭桥术后呼吸衰竭的预防策略。方法本组35例冠状动脉搭桥术，其中体外循环下冠状动脉搭桥术28例，非体外循环下冠状动脉搭桥术7例。主要呼吸功能保护策略包括：术前的呼吸肌锻炼，术中的呼吸功能保护，术后的呼吸机辅助呼吸和呼吸道管理。结果本组无一例呼吸衰竭发生。结论围术期有多种因素影响冠状动脉搭桥术患者的呼吸功能。积极的呼吸功能保护策略能有较好的临床效果。

Preyention of reslpixatory failure in palients undergoing coronary artery bypass grafting

Aim To explore prevention strategies of respiratory failure in patients undergoing coronary artery bypass grafting. Methods 35 patients underwent coronary artery bypass grafting：on-pump coronary artery bypass grafting with extracorporeal circulation in 28 patients （80%）, off-pump coronary artery bypass grafting （OPCAB）in 7 patients （20%）, Our peri-operation respiratory management strategies included：preoperative respiratory muscle training, pulmonary protection during surgery, mechanical ventilation support and respiratory tract manage afteroperation. Result There were no respiratory failure. Conclution There are many factors that affect pulmonary function during perioperative period. Active pulmonary function protection will produce better outcome.
