舒芬太尼麻醉在老年患者全麻诱导期对血流动力学的影响

目的：研究舒芬太尼在老年患者全麻诱导中对血流动力学的影响。方法：选择拟行全身麻醉的老年患者40例，随机分为两组，每组20例，实验组诱导时用舒芬太尼，对照组用芬太尼，分别记录麻醉前、诱导后2min、插管时、插管后1，3，5和10min各时点的平均动脉压、心率、心输出量、心脏指数、每搏输出量、外周血管阻力、心肌加速度指数。结果：实验组平均动脉压、心率在插管时和插管后1min明显低于对照组（P〈0．05）。观察期间实验组心输出量、心脏指数均无明显变化（P〉0．05），而对照组在诱导后、插管时和插管后心输出量、心脏指数明显低于诱导前（P〈0．05）。结论：与芬太尼相比，舒芬太尼在老年患者全麻诱导过程中平均动脉压、心输出量、心脏指数、心率等血流动力学指标影响较少，能更好地保持循环系统的稳定。

Effect of sufentanil anesthesia on the hemodynamics in the induction of general anesthesia in geratics

Objective To study the effects of sufentanil on the hemodynamics in the induction of general anesthesia in geratics.Methods Forty cases of geratics were selected under general anesthesia.They were divided into 2 groups,20 cases in each group.In experiment group,sufentanil was used for induction.In control group,fentanyl was used for induction.The values of MAP,heart rate,CO,CI,SV,SVR and ACI were recorded before anesthesia,2 minutes after induction,at the point of intubation,1,3,5,10 minutes after intubation.Results The values of MAP and heart rate in experiment group were smaller than in control group at the point intubation and 1 minute after intubation(P<0.05).There was no significant difference of the values of CO,CI at each time in experiment group(P>0.05).But there was a significant difference in the values of CO and CI between after induction,at the point of intubation and after intubation in control group(P<0.05).Conclusion Compared to fentanyl,the values of hemodynamics will be less affected during the process of the induction of general anesthesia with sufentanil and can keep the circulation system stable.
