利多卡因对气管拔管心血管反应的作用及护理观察

目的观察利多卡因对气管拔管心血管反应的治疗作用。方法选择40例ASAI～II级,全麻下行妇科腹腔镜手术的患者,随机分为两组,对照组（C组）和利多卡因组（L组）,分别于气管拔管前2min静注生理盐水5ml和利多卡因1.5mg/kg。记录气管拔管前后收缩压、舒张压和心率的变化。结果与基础值比较,对照组拔管后收缩压、舒张压和心率显著升高,利多卡因组拔管后的心血管反应显著低于对照组。结论气管拔管前2min静注利多卡因1.5mg/kg,有效抑制了气管拔管的心血管反应,有利于气管拔管的护理。

Effects of lidocaine on cardiovascular responses to tracheal extubation and nursing observation

Objective To investigate the effect of lidocaine on the haemodynamic responses to tracheal extubation. Methods Forty gynecology patients（ ASA I-II） who underwent elective laparoscopic surgery were randomly assigned into two groups,group℃received 5 ml of 0. 9% saline and group D received lidocaine 1. 5 mg /kg,These medications were given 2 min before tracheal extubation. Changes in SAP,DAP and HR were measured during and after tracheal extubation. Results Patients who received saline showed a significant increase in SAP、DAP and HR associated with tracheal extubation compared to the basline. These increases after tracheal extubation were reduced in lidocaine-treated patients compared with that of the control group. Conclusion Iv lidocaine 1. 5 mg /kg before extubation significantly attenuated the haemodynamic response to tracheal extubation,and this benefical effect have facility in nursing.
