星状神经节阻滞对高血压患者全身麻醉血流动力学的影响

Effect of stellite ganglion block on the hemodynamics in patients with hypertension undergoing general anesthesia

目的:观察星状神经节阻滞(SGB)对高血压患者全麻手术血流动力学的影响。方法:将42例全麻下手术患者随机分为观察组和对照组,各21例,观察组麻醉前采用1%利多卡因行SGB,对照组不进行SGB。观察两组患者麻醉前(T0)、诱导后(T1)、插管即刻(T2)、插管后5 min(T3)、切皮时(T4)、拔管前(T5)、拔管即刻(T6)、拔管后5 min(T7)的收缩压(SBP)、舒张压(DBP)、平均动脉压(MBP)、心率(HR)和心率收缩压乘积(RPP)的变化。结果:两组患者T0时点比较差异无统计学意义,T2～T7差异均有统计学意义,观察组各时点与T0时点数值差小于对照组,两者比较差异有统计学意义。结论:高血压患者全麻前行SGB可缓解麻醉插管、拔管或手术强刺激引起的循环波动,有利于其血流动力学稳定。

Objective：To observe the effect of stellite ganglion block（SGB）on the in patients with hypertension undergoing general anesthesia. Methods：Forty-two patients received operation with general anesthesia were randomly divided into the observation group and the control group with 21 cases each. The patients in the observation group re- ceived SGB before anesthesia using lidocaine 1% ,and those in control group no SGB. Systolic blood pressure（SBP）, diastolic blood pressure （DBP）,mean arterial pressure （MBP）,heart rate （HR）,heart rate and systolic blood pressure product （RPP）of all patients were recorded before anesthesia （T0）,after induction （T1）,at the time of tracheal intuba- tion （T2）, 5 min after tracheal intubation （T3）, during incision （T4）, before extubation （T5）, at the time of extubation （T6）, 5 min after extubation（T7）. Results：There were no obvious difference at To between two groups about all pa- rameter ,and a significant differences at T2-T7. The differences between To and T2-T7 in observation group were less than in the control group,there was significant difference between the them. Conclusion：For patients with hyperten- sion,receiving SGB before general anesthesia can alleviate fluctuations of hemodynamics caused by tracheal intuba- tion,traebeal extubation or stronger stimuli from operation and is in favor of their hemodynamic stability.
