i-gel® from Intersurgical: clinical evidence listing

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

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.

Influence of Head and Neck Position on Oropharyngeal Leak Pressure and Cuff Position with the ProSeal Laryngeal Mask Airway and the I-Gel: A Randomized Clinical Trial

Mishra SK, Nawaz M, Satyapraksh MV, Parida S, Bidkar PU, Hemavathy B, Kundra P. Anesthesiol Res Pract. 2015;2015:705869

After induction of anaesthesia and device insertion, head position was ranomly changed from neutral to flexion, extension and lateral rotation. Leak pressure, fibreoptic view and ventilation scores were among the results measured. Effective ventilation can be performed with both devices, but 'extreme precaution' should be taken in flexion position in ProSeal.
