TAPB复合右美托咪定对行腹股沟斜疝修补术老年患者镇痛效果的影响

Influences on analgesic effect of TAPB combined with dexmedetomidine on elderly patients undergoing oblique inguinal hernia repair

目的:分析超声引导腹横肌平面阻滞(TAPB)复合右美托咪定(Dex)对腹股沟斜疝修补术老年患者镇痛效果的影响。方法:选取84例腹股沟斜疝修补术老年患者,按照随机数字表法分为对照组和实验组,每组各42例。对照组采用全身麻醉,实验组采用TAPB复合Dex麻醉,对比两组血流动力学、镇静及镇痛效果。结果:麻醉前(T_(1)),两组平均动脉压(MAP)、心率(HR)比较,差异无统计学意义(P>0.05);切皮时(T_(2))、术毕(T_(3)),两组平均动脉压(MAP)、心率(HR)比较,差异有统计学意义(P<0.05);术后6 h、24 h、48 h,实验组Ramsay镇静评分、视觉模拟评分(VAS)均低于对照组(P<0.05)。结论:对于腹股沟斜疝修补术老年患者,采用TAPB复合Dex麻醉有利于血流动力学稳定,可提高镇静、镇痛效果。

Objective:To analyze the analgesic effect of ultrasound-guided transversus abdominis plane block(TAPB)combined with dexmedetomidine(Dex)on elderly patients undergoing oblique inguinal hernia repair.Methods:84 elderly patients with oblique inguinal hernia repair were divided into the control group and experimental group,with 42 cases in each group by the table of random mumber.The control group received general anesthesia,while the experimental group received TAPB combined with Dex anesthesia.The hemodynamics,sedative and analgesic effects of the two groups were compared.Results:There were no statistical differences of the mean arterial pressure(MAP)and heart rate(HR)between the two groups before anesthesia(T_(1))(P>0.05);there were statistical differences of the MAP and HR at the time of skin resection(T_(2))and after surgery(T_(3))between both groups(P<0.05);Ramsay sedative scores and visual simulation(VAS)scores in the experimental group were lower than those in the control group at 6 h,24 h and 48 h after operation(P<0.05).Conclusion:TAPB combined with Dex is beneficial to the hemodynamic stability and able to improve sedative and analgesic effects on elderly patients undergoing oblique inguinal hernia repair.
