Clinical and fibreoptic assessment of positioning of the size 1 laryngeal mask airway was performed in 50 infants. A clinically patent airway was obtained in 47 patients at the first attempt, but perfect positioning, as assessed by fibreoptic laryngoscopy, was found in only 22 instances. Despite an airway initially patent, delayed airway obstruction occurred in 12 infants. It is concluded that clinical airway patency does not guarantee ideal positioning of LMA in infants, and that care should be taken to ensure continued airway patency because of the tendency of the LMA position to deteriorate in this group of children.
对50名婴儿进行了1号喉罩气道位置的临床和纤维喉镜评估。47例患者首次尝试时获得了临床上通畅的气道，但经纤维喉镜检查评估，仅22例达到了完美定位。尽管气道最初通畅，但12名婴儿出现了延迟性气道梗阻。结论是，临床气道通畅并不能保证婴儿喉罩气道的理想定位，并且由于该组儿童喉罩位置有恶化的倾向，应注意确保气道持续通畅。
