Assessment of suitability of i-gel and laryngeal mask airway-supreme for controlled ventilation in anesthetized paralyzed patients: A prospective randomized trial.

Context: Laryngeal mask airway supreme (LMA-S) has an inflatable cuff while i-gel has a noninflatable cuff made of thermoplastic elastomer.

Aims: To study the efficacy of ventilation and the laryngeal seal pressures (LSPs) with either device. Our secondary objectives were to compare the ease of insertion, adequacy of positioning the device, hemodynamic response to device insertion, and any postoperative oropharyngeal morbidity.
