利多卡因超声雾化表面麻醉用于支气管镜检查的效果观察

目的:比较2种表面麻醉方法在支气管镜检查中的效果.方法:将需要进行支气管镜检查的120例患者,随机分为A、B组,每组60例.A组应用利多卡因超声雾化吸入法,B组应用利多卡因喉头喷雾法.比较2组患者检查前、检查中的血氧饱和度、脉搏、心率、呼吸频率、呛咳和不良反应记忆率,以及检查后愿意再次接受检查率.结果:检查中B组氧饱和度明显低于A组,而心率和呼吸频率明显高于A组(P<0.01);A组患者发生呛咳、检查后不良记忆少于B组,麻醉效果(优良率)和愿意再次检查高于B组(P<0.01);A组达到有效麻醉的平均耗药量明显少于B组(P<0.01).结论:超声雾化吸入法麻醉效果好,达到有效麻醉时间短,用药量少,患者痛苦少,操作者受干扰少,能保证支气管镜检查的顺利进行,可以广泛应用于临床.

The effects of ultrasonic atomization surface anesthesia with lidocaine on bronchoscopy

Objective:To compare the effects of two kinds of anesthesia on bronchoscopy.Methods:One hundred and twenty patients were randomly divided into group A(60 cases),which were used by ultrasound inhalation method,and group B(60 cases),which were used by throat spray.The oxygen saturation,pulse,heart rate,respiratory rate,cough and adverse reaction rates of memory of two groups were observed before examination and in process of examination and the reexamination rates were investigated after examination.Results:The oxygen saturation of group B was significantly lower than that of group A,while its heart and respiratory rates were significantly higher than that of group A(P<0.01).The cough,bad memory and the average consumption amount of drugs of group A were less than that of group B,while its anesthesia effects and reexamination rates were higher than that of group B(P<0.01).Conclusions:The ultrasonic atomization surface anesthesia is of good efficacy,short time to achieve effective anesthesia,less medication,less pain of the patient and less interference of the operator,which can ensure the smooth progress of bronchoscopy and be widely used in clinical.
