Comparative study of three supraglottic airways as conduits in patients with predicted difficult laryngoscopy. Primary outcome measure was success rate of tracheal intubation through the device. No statistical difference was recorded in success rates between devices, however i-gel proved quicker to insert compared to ILMA and the intubation time was shorter compared to CTrach. i-gel is a suitable alternative to sILMA and CTrach in this scenario, and the shorter times recorded may provide an advantage in cases of difficult oxygenation.
