Summary

Clinical and fibreoplic 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.
