文摘目的分析探讨阿片类药物使用与阻塞性睡眠呼吸暂停(obstructive sleep apnea,OSA)患者围手术期严重呼吸抑制事件的相关性,提高临床防治水平。方法回顾分析2016年1月至2018年12月本院收治的8例发生围手术期严重呼吸抑制的OSA病例的临床资料,并与同期20例患病及治疗情况类似但未发生上述危象的病例比较,分析病情严重程度、麻醉药物应用、术后拔管时间、术后苏醒室观察时长及术后镇痛药物应用等与上述事件的关系。结果围手术期呼吸抑制组和对照组相比年龄、体质量指数(body mass index,BMI)差异无统计学意义(P>0.05)。与对照组相比,呼吸抑制组阿片类药物使用率高、术后至拔除气管插管时间更短、术后麻醉苏醒室观察总时间更短,差异具有统计学意义(P<0.05)。结论OSA疾病存在呼吸中枢等多脏器潜在损害,阿片类药物应用可能增加患者围手术期呼吸抑制风险;适当延长术后拔管时间和麻醉苏醒室观察时间,尽量避免在围手术期使用阿片类药物镇痛,有助于减少运转途中或病房中突发呼吸抑制意外的发生。
