1、不同麻醉用药对老年患者麻醉后苏醒时间及术后认知功能影响的对比摘要:目的对比七氟烷和异氟烷对老年患者腹部手术后苏醒时间及认知功能的影响。方法选择在我院行择期腹部手术的患者98例,ASAⅠ~Ⅲ级,中位年龄68(61~78)岁,随机分为七氟烷组(S组)和异氟烷组(I组),每组49例。记录两组患者苏醒时间、拔管时间以及定向力恢复时间,并使用简易精神状态量表(MMSE)分别对两组患者在术前1d和术后1、3、6及24小时进行评分(总分30分),<24分为术后认知功能障碍(POCD)。结果两组患者平均苏醒时间无差别
2、(P>0.05),七氟烷组的平均拔管时间及定向力恢复时间少于异氟烷组(P<0.05)。两组患者在术后1小时及3小时,MMSE评分均低于术前基线水平(P<0.05),而异氟烷组较七氟烷组更低(P<0.05),术后6小时及24小时时,两组患者评分与基线水平无差异,两组之间也无明显差异(P>0.05)。术后1小时及3小时,七氟烷组的POCD发生率明显低于异氟烷组(P<0.05);术后6小时及以后,两组之间POCD发生率无明显差异(P>0.05)。结论在老年患者腹部手术中,使用七氟烷麻醉的拔管及定向力恢复时间
3、少于异氟烷,在麻醉后6小时内,七氟烷对于患者术后认知功能恢复较异氟烷更有优势。关键词:七氟烷;异氟烷;麻醉;术后认知功能紊乱中图分类号:R-614R614.2文献标识码:AComparisonofcognitivefunctionandrecoveryaftersevofluranceorisofluranceanaesthesiaintheelderlypatienntsABSTRACT:ObjectiveTocomparepostoperativerecoveryandcognitivefunct
