靶控输注依托咪酯与异丙酚在老年患者全麻诱导时的应用
Modern Medicine & Health(2011)
Abstract
目的:观察依托咪酯、异丙酚靶控输注(target-controlled infusion,TCI)在老年患者全麻诱导时的应用,比较血流动力学的影响。方法:48例ASAⅡ~Ⅲ老年全麻患者随机分为异丙酚组(A组,n=24)和依托咪酯组(B组,n=24),麻醉诱导A组和B组均采用TCI系统诱导给药,并加用咪达唑仑0.08 mg/kg,芬太尼4μg/kg,罗库溴铵0.6 mg/kg,观察记录两组患者诱导前、诱导后、插管即刻和插管后3 min时MAP、HR的变化。结果:诱导后A组SBP、DBP和HR均下降明显(P<0.05),B组则轻度下降或下降不明显(P>0.05)。结论:丙泊酚、依托咪酯在老年人靶控输注(TCI)全麻诱导时均可造成一过性的血流动力学变化,但依托咪酯的影响明显小于丙泊酚(P<0.05)。
