术前气管切开对预防重症阻塞性睡眠呼吸暂停低通气综合征围术期严重并发症的临床意义

目的：探讨重症阻塞性睡眠呼吸暂停低通气综合征(OSAHS)术前气管切开对UPPP／腭咽成形术(PPP)手术中、手术后严重并发症的预防作用以及对整个手术安全性的意义。方法：分析我科1998～2003年104例手术治疗的重症OSAHS患者，将其分为术前气管切开组和非气管切开组，重点分析两组患者术中、术后并发症的发生情况及严重性。结果：对重症OSAHS患者的治疗中，术前气管切开组并发症(尤其是危及生命的并发症)发生率(30．4％，7／23)明显低于非术前气管切开组(53．1％，43／81)。结论：对于重症OSAHS患者的治疗，术前气管切开是预防术中、术后严重并发症的有效措施，对确保手术的安全性十分必要。

Clinical significance of preoperative tracheotomy in preventing perioperative OSAHS severe complications

Objective:Studying the value of preoperative tracheotomy in preventing obstructive sleep apnea-hypopnea syndrome(OSAHS) severe complications in preoperative and postoperative period of UPPP/PPP and the its significance in ensuring the safety of surgical operation.Method:One hurdred and four OSAHS severe cases were retrospective analysed from July 1998 to July 2003, and these cases were divided into tracheotomy group and non-tracheotomy group. Preoperative and postoperative complications of these cases were studied.Result:The incidence of complications especially severe complications endangering life in tracheotomy group was lower significantly than in non-tracheotomy group.Conclusion:It is very necessary to do tracheotomy preoperatively so as to preventing severe complications of OSAHS and ensuring the safety of surgical operation.
