i-gel® from Intersurgical: clinical evidence listing

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

A comparison of QTc intervals after laryngoscopic intubation and i-gel insertion during propofol-sevoflurane anaesthesia

Byon HJ, Song J, Shinn HK, Song K, Lee C, Lim H. Minerva Anestesiol. 2016 Sep;82(9):950-6

Patients were randomly assigned to either the i-gel or intubation group and induced using propofol or sevoflurane. Peak QTc interval was lowever in the i-gel group. Authors conclude the i-gel 'may be advantageous' to patients at risk of QTc prolongation.

Retrospective cohort investigation of perioperative upper respiratory events in children undergoing general anesthesia via a supraglottic airway

No HJ, Koo BW, Oh AY, Seo KS, Na HS, Ryu JH, Lee SW. Medicine (Baltimore) 2016 Jul;95(28):e4273.

Observational analysis of medical records of previous anaesthetic procedures at one university hospital. Comparison of the two anaesthetic agents included use of four supraglottic airways: LMA Flexible, LMA Supreme, LarySeal and i-gel.

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.

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.

Is I-gel airway a better option to endotracheal tube airway for sevoflurane-fentanyl anesthesia during cardiac surgery?

Elgebaly AS, Eldabaa AA. Anesth Essays Res. 2014 May-Aug;8(2):216-22

49 adult patients were randomly assigned between each device group, with fentanyl doses, hemodynamic parameters and mean arterial pressure among results taken at various points throughout the procedure. i-gel requires less anaesthetic doses in this scenario.
