Evaluation of the Pediatric Igel Airway in 250 Children

This study has been terminated.
(Initial number of 250 was not based on sample size. Most airway studies use n=100 therefore trial stopped when 120 children recruited)

Once a child has been anaesthetised and is fully asleep, a special airway tube called a laryngeal mask is often inserted into their mouth to help with their breathing. This tube is removed just before the child wakes up.

A new type of airway tube, called an i-gel airway, has been developed for children, which is hoped will be easier to insert, safer once in position, and will be less likely to cause a sore throat after the anaesthetic than a standard laryngeal mask. The adult i-gel airway has been available for adults since 2007, and early trials have shown very encouraging results.
