超声引导下椎旁神经阻滞麻醉复合右美托咪定在经皮肾镜碎石手术中的效果分析

Efficacy of ultrasound-guided paravertebral nerve block anesthesia plus dexmedetomidine in PCNL

目的:观察经皮肾镜碎石手术现状,分析行超声引导下椎旁神经阻滞麻醉复合右美托咪定的效果。方法:借助随机抽样法将2019年1-12月期间在本院接受经皮肾镜碎石手术治疗的60例患者分为两组,分别给予硬腰联合麻醉、超声引导下椎旁神经阻滞麻醉复合右美托咪定,对比两组的麻醉效果、镇静情况及血流动力学指标。结果:研究组患者麻醉操作时间、麻醉药物起效时间均短于对照组(P<0.05),而麻醉药物维持时间则长于对照组(P<0.05);研究组患者镇静评分优于对照组(P<0.05);麻醉前15 min两组患者血流动力学指标水平差异不明显(P>0.05),麻醉45 min后研究组患者血流动力学指标水平低于对照组(P<0.05)。结论:经皮肾镜碎石手术患者接受超声引导下椎旁神经阻滞麻醉复合右美托咪定,麻醉药物起效快,维持时间长,且能有效进行镇静,使血流动力学指标维持稳定,利于患者术后康复。结论:经皮肾镜碎石手术患者接受超声引导下椎旁神经阻滞麻醉复合右美托咪定,麻醉药物起效快,维持时间长,且能有效进行镇静,使血流动力学指标维持稳定,利于患者术后康复。

Objective:To observe the current status of percutaneous nephrolithotomy and analyze the effect of ultrasound-guided paravertebral nerve block anesthesia with dexmedetomidine.Methods:60 patients were divided into two groups,and they were given combined spinal-epidural anesthesia and ultrasound-guided paravertebral nerve block anesthesia with dexmedetomidine,respectively.Results:The operation time of anesthesia and the onset time of anesthetic drugs in the study group were shorter than the control group(P<0.05).While the maintenance time of anesthetics was longer than the control group(P<0.05).The sedation score in the study group was better than the control group(P<0.05).15 minutes before anesthesia,there was no significant difference in hemodynamic index levels between two groups(P>0.05).45 minutes after anesthesia,the hemodynamic index levels in the study group were lower than those in the control group(P<0.05).Conclusion:Patients undergoing ultrasound-guided paravertebral nerve block anesthesia with dexmedetomidine showed better anesthetic effect,with long maintenance time,and can be effectively sedated to maintain hemodynamic indicators,which is conducive to the recovery of patients after surgery.
