50 patients had the i-gel® inserted for ventilation during surgery. The number of insertion attempts, insertion time, manipulations required for an effective airway and seal pressure were recorded. Gastric tube placement and adverse events were also noted where they occurred. Before removal of the device, stability was tested by measuring the expiratory tidal volume with the patient’s head in standard, rotated, chin lift and no-pillow positions. Success rate was 90% at the first attempt and 100% at the second. Median insertion time was 11 seconds. Insertion depth was increased in four patients and a jaw thrust was required in two more. All gastric tubes were placed successfully. Mild cough or postoperative sore throat was seen in a total of four patients. Seal pressure was approximately 20cm H2O. The i-gel® was also found to be stable during head and neck movement.
