The use of an i-gel® supraglottic airway for the airway management of a patient with subglottic stenosis: a case report

Donaldson W, Michalek P. Minerva Anestesiol 2010; 76(5): 369-372

This report details the case of a 47-year-old woman with subglottic stenosis. During preoperative screening she stated that there had been difficulty inserting an endotracheal tube during an earlier procedure. During anaesthesia, a size four i-gel® was inserted on the first attempt. A fibrescope was passed down the i-gel® and into the trachea, where subglottic stenosis could be seen. The i-gel® showed no signs of leaking and did not cause any trauma. The authors note that this is the first case report where an i-gel® has been used in a patient with subglottic stenosis, and state that preoperative tests should be carried out before choosing to use the device in this situation.
