目的:评价Ambu AuraGain喉罩用于无痛纤维支气管镜检查术患者气道管理的效果。方法:择期行无痛纤维支气管镜检查术患者60例，性别不限，ASA分级Ⅰ～Ⅲ级，年龄30～64岁，体重45～80 kg，Mallampati分级Ⅰ～Ⅲ级，采用随机数字表法将其分为2组(n n＝30)：Ambu AuraGain喉罩组(A组)与Supreme喉罩组(S组)。麻醉诱导后置入喉罩，术中使用间歇正压模式通气维持Pn ETCOn 2 30～45 mmHg、SpOn 2>95%。纤维支气管镜经过喉罩出口末端时记录Brimakombe评分，评价喉罩对位准确情况。分别于麻醉诱导后成功置入喉罩时和纤维支气管镜检查结束即刻，记录气道密封压。记录喉罩置入时间、置入成功情况、首次置入成功情况和喉罩拔除时间。记录术中低氧血症、高血压、心动过速和喉罩拔除后低氧血症、咽喉疼痛、喉罩粘血的发生情况。记录内镜医师对纤维支气管镜检查操作的满意度。n 结果:2组喉罩置入时间、置入成功率、首次置入成功率、喉罩拔除时间、术中和喉罩拔除后不良反应发生率比较差异无统计学意义(n P>0.05)。与S组比较，A组喉罩对位准确率和检查结束即刻气道密封压升高，内镜医师满意度升高(n P 95%.The Brimacombe score was recorded while the fiberoptic scope was advanced to the end of the exit of the laryngeal mask, and the accuracy of the laryngeal mask alignment was evaluated.The oropharyngeal leak pressure was recorded when LMA was successfully placed after anesthesia induction and immediately after the examination.The insertion time, success rate of placement, success rate of inserting LMA at first attempt, and the extubation time were recorded.The incidence of intraoperative hypoxemia, hypertension, tachycardia, and occurrence of hypoxemia, sore throat, and blood stains on the LMA after removal of LMA were recorded.The endoscopic physician′s satisfaction with the operation of fiberoptic bronchoscopy was recorded.n Results:There were no significant differences in terms of insertion time, success rate of placement, success rate of insertion at first attempt, extubation time, and incidence of adverse reactions during operation and after removal of LMA between the two group (n P>0.05). Compared with group S, the accuracy of the laryngeal mask alignment and oropharyngeal leak pressure immediately after the examination were significantly increased, and endoscopic physician′s satisfaction was increased in group A (n P<0.05).n Conclusion:Ambu AuraGain LMA can be safely and effectively used for airway management in the patients undergoing painless fiberoptic bronchoscopy.
