为观察围手术期持续正压通气治疗（ＣＰＡＰ）对重症阻塞性睡眠呼吸暂停综合征（ＯＳＡＳ）患者的影响，对１２例重症ＯＳＡＳ进行了围手术期ＣＰＡＰ治疗，对患者治疗前后呼吸紊乱指数（ＡＨＩ）、血压等指标进行观察，所有患者均接受了半导体激光腭咽成形术。经ＣＰＡＰ治疗后１２例患者ＡＨＩ下降，临床症状消失，无手术并发症出现，术前合并高血压的４例经ＣＰＡＰ治疗后血压恢复正常。提示重症ＯＳＡＳ患者围手术期应用ＣＰＡＰ治疗能够提高手术耐受性，减少手术危险性。
To observe the effect of perioperative continuous positive pressure ventilation (CPAP) on patients with severe obstructive sleep apnea syndrome (OSAS), 12 patients with severe OSAS underwent perioperative CPAP. The changes of respiratory disturbance index AHI), blood pressure and other indicators were observed, all patients received a semiconductor laser velopharyngeal plasty. After CPAP treatment, 12 patients with AHI decreased, clinical symptoms disappeared, no surgical complications occurred in 4 cases of preoperative hypertension with CPAP blood pressure returned to normal. Tip perioperative application of CPAP in patients with severe OSAS can improve the surgical tolerance and reduce the surgical risk.
