Clinical and fibreoptic assessment of the positioning of the laryngeal mask airway was performed in 100 children. Clinical observation indicated a patent airway in 98% and severe airway obstruction in 2% of cases. Perfect positioning, as judged by fibreoptic laryngoscopy, was found in 49% and the epiglottis was within the mask in 49%. Fibreoptic evidence of partial airway obstruction in 17% was not detected clinically.
对100名儿童进行了喉罩气道定位的临床及纤维喉镜评估。临床观察显示，98%的病例气道通畅，2%的病例存在严重气道梗阻。经纤维喉镜检查判断，49%的病例定位完美，49%的病例会厌位于喉罩内。临床上未检测到17%的存在部分气道梗阻的纤维喉镜证据。
