i-gel® from Intersurgical: clinical evidence listing

A comprehensive list of all known published clinical evidence on the device

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

Radhika KS, Sripriya R, Ravishankar M, Hemanth Kumar VR, Jaya V, Parthasarathy S. Anesth Essays Res. 2016;10(1):88-93

Patients were split into i-gel and LMA Supreme groups, with insertion attempts, time and any manoeuvres needed forming outcomes, along with peak inspiratory pressure (PIP).  LMA-S was inserted successfully in more patients, but with no significant difference in PIP.

Application of the LMA-Supreme™ and i-gel™ laryngeal masks during pelvic operations in adults

Wang F, Zhang R. Asian J Surg. 2016 Jan;39(1):1-5

90 patients divided into two groups, i-gel and LMA Supreme. Latter group required less time to insertion and gastric tube indwelling time, but i-gel group had fewer complications. Authors conclude both devices are safe and effective for this procedure.

Optimum sevoflurane concentration for I-gel insertion in unpremedicated children

Ghai B, Sethi S, Bansal D, Ram J. J Clin Anesth. 2015;27(8):627-31

Patients were randomly assigned to i-gel size 2 or LMA Classic size 2 groups, with target end-tidal sevoflurane concentration maintained for 8-10 minutes before insertion. This concentration was decreased in subsequent patients depending on response according to Dixon method. Authors conclude i-gel insertion can be accomplished at nearly half the concentration required for LMA Classic.

Evaluation of I-gel™ airway in different head and neck positions in anesthetized paralyzed children

Jain D, Ghai B, Bala I, Gandhi K, Banerjee G. Paediatr Anaesth. 2015;25(12):1248-53

30 children induced with sevoflurane in oxygen and administered atracurium intravenously. Oropharyngeal leak pressure in neutral, maximum flexion and maximum extension were primary outcomes measured. In extreme flexion of head and neck, caution is warranted during ventilation.
