Comparison of the reinforced laryngeal mask airway and tracheal intubation for adenotonsillectomy.

One-hundred and four patients were allocated randomly to receive anaesthesia for adenotonsillectomy via either a reinforced laryngeal mask airway or tracheal tube. Airway maintenance and protection were assessed during and after operation. The reinforced laryngeal mask did not interfere with surgical access; it resisted compression and protected the lower airway from contamination with blood. Four patients were withdrawn from the laryngeal mask airway group: two because difficulty with placement, and two because the laryngeal mask was obstructed distally when the Boyle Davis gag was opened fully. In children, recovery was less eventful in the laryngeal mask airway group, with less airway obstruction (P < 0.001) and better airway acceptance (P < 0.05). The reinforced laryngeal mask airway provided a clear, secure airway until recovery of protective reflexes.
