History of Changes
  Purpose

Randomized controlled trial comparing performance of the I-gel and disposable Laryngeal Mask Airways under controlled ventilation. 200 patients, 100 in each arm. Measurement of peak airway and sealing pressures. Postoperative questionnaires at 1 and 24hrs.

Hypothesis

There is no difference between the performance* of the I-gel and disposable laryngeal mask airways for controlled ventilation under general anesthesia.

*as defined by peak airway pressure and sealing pressures.
