复方利多卡因乳膏对小儿扁桃体伴腺样体切除术全麻苏醒期的影响

Effect of compound lidocaine cream on the recovery period of general anesthesia in pediatric patients undergoing tonsillectomy with adenoidectomy

目的探讨复方利多卡因乳膏涂抹气管导管对小儿扁桃体伴腺样体切除术全麻苏醒期的影响。方法120例择期行扁桃体伴腺样体切除术患儿采用随机数字的方法分为试验组和对照组：试验组麻醉前将复方利多卡因乳膏均匀涂抹气管导管表面；对照组麻醉前将石蜡油均匀涂抹于气管导管表面。观察记录2组患儿在苏醒期血流动力学的变化及并发症的发生情况。结果试验组患儿在麻醉苏醒期血流动力学各项指标较对照组更稳定，对照组患儿耐管性较差，呛咳、烦躁、咽痛等并发症发生率增加（P＜0.05）。结论复方利多卡因乳膏涂抹气管导管表面可有效减轻全麻苏醒期呛咳等应激反应，降低术后烦躁的发生率，提高患儿术后的安全性。

Objective To investigate the effects of compound lidocaine cream applied to tracheal tube on the recovery of tonsil withadenoidectomy in general anesthesia.Methods120patients undergoing elective tonsillectomy with adenoidectomy were randomly divided into theexperimental group and the control group.In the experimental group,the surface of the tracheal tube was uniformly coated with compound lidocainecream before anesthesia.In the control group,paraffin oil was given evenly to the surface of the tracheal tube.The changes of hemodynamics andthe incidence of complications in the two groups were observed and recorded.Results The indexes of hemodynamics in the experimental groupwere more stable than those in the control group,and the control group had poor tube resistance,and the incidence of complications such as cough,irritability and sore throat was increased(P<0.05).Conclusion Application of compound lidocaine cream on tracheal tube surface can effectivelyreduce the cough and other stress response during the general anesthesia recovery period,decrease postoperative irritability and improve the safety ofchildren after surgery.
