i-gel® from Intersurgical: clinical evidence listing

Peutrell I, Jennison N. British Journal of Midwifery 2014 May; 22(5): 254-8

Twenty midwives asked to manage newborn resuscitation scenarios on a manikin using two techniques: Bag valve mask with a Guedel, and a bag with an i-gel. Time to first breath quicker with i-gel, no significant difference in duration of inflation breaths. Higher inflation pressures generated with i-gel.

In this double-blind study, the scenario was made more difficult by using a cervical collar. Primary aim was to compare leak pressures between devices, with success rate, insertion and fibreoptic view other parameters measured. First attempt success and leak pressure was higher with LMA Supreme. Both devices proved effective, and differences may not be clinically significant.

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.
