Br J Surg:术中应用右美托咪定预防术后老年非心脏手术患者谵妄:随机临床试验

术中使用右美托咪啶可使老年人在非心脏大手术后发生谵妄的风险减半。

背景与目的

老年患者术后常发生谵妄,预后差。本研究旨在探讨术中应用右美托咪定对老年大手术患者谵妄发生率的影响。

方  法

这是一项随机、双盲、安慰剂对照试验。将计划进行大型非心脏手术的老年患者(60岁以上)随机分为两组。治疗组在麻醉诱导前10min给予负荷量右美托咪啶0.6ug/kg,然后持续输注(0.5ug/kg/h)至手术结束前1h。对照组患者在相同的时间内接受相同剂量的生理盐水。主要评估指标是术后前5天内的谵妄发生率。采用混合评估法(CAM)对非机械通气患者和重症监护病房机械通气患者进行谵妄评估。

结 果

共纳入309例接受右美托咪定治疗的患者和310例对照组患者进行意向治疗分析。右美托咪啶治疗组术后5d内谵妄发生率较低:治疗组5%(17/309),低于对照组10%(32/310)。右美托咪定治疗组术后30天并发症的总发生率也较低,治疗组(309人中的60人)占19.4%,对照组(310人中的81人)占26.1%(RR 0.74, 0?55 to 0.99, P = 0?047)。

结 论

术中使用右美托咪啶可使老年人在非心脏大手术后发生谵妄的风险减半。
