Anesthesia Effect and Safety of Ultrasound-Guided Nerve Block Combined with Dexmedetomidine in Pediatric Inguinal Surgery

目的探讨超声引导神经阻滞联合右美托咪定在小儿腹股沟区手术的麻醉效果及安全性。方法选取2016年11月至2018年11月于我院接受择期行单侧腹股沟区手术的80例患儿,按随机数字表法分为治疗组和联合组,每组40例。治疗组给予舒芬太尼和丙泊酚麻醉,联合组给予超声引导神经阻滞联合右美托咪定麻醉,观察比较两组患儿手术麻醉情况、血流动力学变化和不良反应发生情况。结果联合组的麻醉诱导时间和术后恢复时间明显少于治疗组(P<0.05);麻醉后,联合组的HR和MAP显著低于治疗组(P<0.05);两组的不良反应发生率比较差异有统计学意义(P<0.05)。结论超声引导神经阻滞联合右美托咪定的麻醉效果较好,有助于维持术中血流动力学稳定,减少麻醉药物使用剂量和不良反应发生率,值得临床推广。

Objective To observe and discuss the anesthetic effect and safety of ultrasound-guided nerve block combined with dexmedetomidine in pediatric inguinal surgery,and to provide reference for clinical application.Methods Eighty children who underwent elective unilateral inguinal surgery in our hospital from November 2016 to November 2018 were divided into treatment group and combination group according to random number table extraction method,40 cases in each group.The control group was anesthetized with sufentanil and propofol,while the observation group was anesthetized with ultrasound-guided nerve block combined with dexmedetomidine.The anesthesia,hemodynamic changes and adverse reactions were observed and compared between the two groups.Results The induction time and recovery time of anesthesia in the combined group were significantly less than those in the treatment group(P<0.05);after anesthesia,HR and MAP in the combined group were significantly lower than those in the treatment group(P<0.05);the incidence of adverse reactions in the two groups was significantly different(X=7.55 correction,P<0.05).Conclusion Ultrasound-guided nerve block combined with dexmedetomidine has a good anesthetic effect,which is helpful to maintain hemodynamic stability and reduce the dosage of anesthetics and the incidence of adverse reactions.It is worthy of clinical promotion.
