目的：探讨罗哌卡因和利多卡因表面麻醉在清醒气管拔管应用效果差异。方法以颌骨骨折患者50例作为研究对象，采用随机数字表法分为A组（25例）和B组（25例），分别在鼻气管插管前给予1%罗哌卡因和2%利多卡因行环甲膜表面麻醉；比较两组患者不同时间点的血流动力学指标，拔管时呛咳发生率及拔管并发症发生情况等。结果两组患者观察组患者T0(入手术室时)和T1(插管时)血流动力学指标比较差异无统计学意义（>0.05）；但A组患者T2(清醒时)，T3(拔管时)及T4(拔管后5 min)时血流动力学指标均显著低于对照组，差异有统计学意义（0.05);the hemodynamics indexes of A group was significant lower than B group in time points of T2(in time of waking),T3(in time of extubation)and T4(5 min after extubation)( <0.05).The incidence of cough in extubation of A group was significant lower than B group ( 0.05).Conclusion Compared with lidocaine,opivacaine with topical anesthesia in awake tracheal extubation can ef iciently relieve cough induced by tracheal extubation stimulation and stable hemodynamics indexes.
