摘　　要：目的:观察异丙酚靶控输注(TCI)用于心内直视手术麻醉诱导时的血流动力学及心率变异性(HRV)变化。方法:28例心脏病患者随机分为A、B两组,A组采用Diprifu-sor/TCI系统分步诱导给药,B组人工推注异丙酚,观察HR、BP、SpO2、ECG、HRV诱导前(T0)、意识消失时(T1)、插管时(T2)、插管后1min(T3)、3min(T4)、5min(T5)变化。结果:A组各时点HR、SpO2、DBP与T0相比无明显变化(P>0.05),HRV、SDP各时点明显低于T0(P<0.05),但插管后无明显异常;B组T1、T2的HR、BP明显低于T0、T3、T4、T5,也明显低于A组各时点(P<0.05),T3的TP、HF明显低于T0和A组(P<0.05)。结论:异丙酚TCI分步诱导可以安全地用于心内直视手术的麻醉诱导。Objective: To observe the hemodynamics and HRV caused by TCI during the induction period of the intracardiac surgery. Methods:28 cases of cardiopathy were chosen and divided into 2 groups as A and B which accepted propfool infusion by Diprifusor/TCI system or by manual respectively. The HR、Bp、SpO_2、ECG and HRV were observed 6 times on T_0(pre-induction), T_1(unconsciousness),T_2(intubating),T_3(1min after intubating),T_4(3mins after intubating) and T_5(5mins after intubating).Results: Hardly any change of the HR,Spo_2 and DBp occurred in the group A compared with those indexes of T_0 while the HRV and SBP decreased on T1 and T_2 as compared with T_0(P<0.05). All the indexes observed in group A on T_3,T_4 and T_5 became normal as T_0 without obvious difference. The HR and Bp of group B on T_1 and T_2 became obviously lower than those on T_0,T_3,T_4 and T_5,and lower than those indexes of group A(P<0.05). Conclusion:The target controlled infusion (TCI) of propfol can be used in anesthesia induction of the intracardiac surgery safely.
