利多卡因联合丙泊酚行无痛支气管镜检查的临床观察

目的观察利多卡因联合丙泊酚行无痛支气管镜检查对患者呼吸与循环的影响。方法60例支气管镜检查患者分两组:常规支气管镜组(Ⅰ组30例)和无痛支气管镜组(Ⅱ组30例),Ⅰ组为单用利多卡因局部表面麻醉组,Ⅱ组为用利多卡因局部表面麻醉联合丙泊酚静脉麻醉组,采用多功能监护仪监测患者术前、术中及术后心率、血压、血氧饱和度、呼吸的变化。用SPSS13.0进行t检验。结果Ⅱ组麻醉后患者能在无知觉和无痛苦中接受检查,两组在术中心率、血压、血氧饱和度、呼吸的变化差异有统计学意义(P0.05);两组在术后心率、呼吸的变化差异有统计学意义(P0.05),而血压、血氧饱和度的变化差异无统计学意义(P0.05)。结论采用利多卡因联合丙泊酚麻醉下行支气管镜检查,麻醉效果好,是一种相对安全的麻醉方法。

Clinical observation of Lidocaine uniting propofol anesthesia during painless bronchoscopy

Objective To investigate the effect of lidocaine uniting propofol anesthesia during painless bronchoscopy on the patients＇respiration and circulation. Methods The 60 patients were divided into two groups：the routine bronehoseopy group（ Ⅰ group,30 patients）and the painless bronchoscopy group（Ⅱ group,30 patients）. The Ⅰ group just chose lidocaine local anesthesia and the Ⅱ group chose lidocaine local anesthesia uniting propofol general anesthesia. The patient＇s heart rate, respiration, blood pressure and saturation of blood oxygen were observed by muhifunctional monitor before,during and after bronchoscopy. T test was conducted using SPSS 13.0. Results The Ⅱ group patients felt senseless and painless during brenchoscopy, Differences of heart rate, respiration, blood pressure and saturation of blood oxygen during brenchoscopy between the two groups were statistically significant（P 〈0. 05 ）. The differences of heart rate, respiration after brenchoscopy between the two groups were statistically significant（ P 〈0.05 ）. The differences of blood pressure and saturation of blood oxygen after bronchoscopy between the two groups were not statistically significant （ P 〉 0. 05 ）. Conclusion Taking lidocaine uniting propofol during brenehoscopy is achieved with satisfying anesthetic effect. The use of lidocaine uniting propofol anesthesia is a relatively safe anesthesia method.
