摘要 目的:探讨右旋美托咪定与丙泊酚降低ICU老年术后谵妄发生的比较分析。方法:根据入选标准,选择105例老年全麻术后入ICU的患者,随机分为两组,A组54例为右旋美托咪定组,B组51例为丙泊酚组。A组手术结束前30min,用注射泵静脉10min内给予右旋美托咪定负荷量0.5~1μg/kg,继以0.2~0.7μg/(kg·h)调整持续泵注;B组术后以TCI丙泊酚靶控浓度1~1.5μg/ml持续输注,递增浓度0.3μg/ml;两组均以达到目标镇静为标准,输注时间至术后24h;两组均给予PCIA术后镇痛,舒芬太尼1.5μg/ml配置100ml,持续泵注2ml/h。观察指标:入ICU后至术后24h,以CAM-ICU法评定诊断患者谵妄状态,并记录患者发生低血压(低于基础压30%)、心率缓慢(<50次/min)、呼吸抑制等不良反应次数。结果:与以往文献相比,两组均能有效降低谵妄发生率,A组术后谵妄发生率更低于B组(P<0.05);在发生低血压、心率缓慢方面,A组与B组无明显差异(P>0.05);B组出现呼吸抑制次数明显高于A组(P<0.05)。结论:右旋美托咪定与丙泊酚均能有效降低ICU老年术后谵妄发生率,但右旋美托咪定效果要优于丙泊酚,且更为安全有效。
