2种麻醉方法在纤维支气管镜检查中的效果比较

Effects of Two Anaesthesia Methods Before Fibrobronchoscopy Examination

目的:比较咽喉部喷雾加环甲膜穿刺麻醉法与超声雾化吸入麻醉法在纤维支气管镜(纤支镜)检查中的应用效果。方法:将60例行纤支镜检查患者随机分为2组:观察组(A组)和对照组(B组)各30例。A组采用咽喉部喷雾加环甲膜穿刺法麻醉,B组采用超声雾化吸入法麻醉。从麻醉效果、麻醉起效时间、平均耗药量及术中生命征变化包括:心率(HR)、收缩压(SBP)、脉搏血氧饱和度(SpO2)方面进行对比分析。结果:A组麻醉效果优于B组,麻醉起效时间及平均耗药量少于B组,术中生命征比B组更为平稳,两组差异有显著意义(P<0.01)。结论:咽喉部喷雾加环甲膜穿刺麻醉法可进一步改善麻醉效果、缩短检查时间、减少麻醉药用量、提高了安全度,值得在临床中进一步推广。

Objective：To study the effects of two anaesthesia methods before fibrobronchoscopy examination：spraying combined with cricothyroid membrane puncture and ultrasonic atomizing inhalation.Methods：60 patients of using fibrobronchoscopy were randomly divided into trial group（A）and normal group（B）.Those in group B received ultrasonic atomizing inhalation anaesthesia,whereas those in group A received spraying combined with cricothyroid membrane puncture anaesthesia.The anaesthesia effects,mean drug consumption,and induction time of anesthesia were recorded.The heart rate（HR）,systolic pressure（SBP）,and pulse oxygen saturation（SpO2）were measured.Results：The level of patient-rated satisfaction was higher in group A than that in group B.The mean drug consumption and induction time of anesthesia was less in group A than that in group B.The vital signs were more stable in group A than that in group B.Conclusion：Spraying combined with cricothyroid membrane puncture has many advantage of being convenient,effective,and safe.It is an ideal anaesthesia method before fibrobronchoscopy examination.
