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.

Manikin study to investigate effectiveness of three fixation methods on an automated chest compressor. Fixation strap may prove useful in stabilising i-gel insertion in this scenario.

Forty lifeguards took part in this manikin study, where time to ventilation and proportion of successful ventilations (both with and without ‘concurrent’ chest compressions) were measured. Mean time to ventilate with i-gel® was 15.6 seconds, compared to 35.2 for Soft Seal and 35.1 for AuraOnce. Authors concluded that ‘most lifeguards preferred the i-gel®’.

A group of 45 nurses inserted the i-gel® and ILMA in a manikin with and without continuous chest compressions. ILMA proved more successful than the i-gel®, but continuation of compressions caused higher insertion times in both devices. Authors conclude that nursing staff can use both devices ‘as conduits with comparable success rates, regardless of whether chest compressions are interrupted or not’.
