Evaluation of six different airway devices regarding regurgitation and pulmonary aspiration during cardio-pulmonary resuscitation (CPR) – A human cadaver pilot study

Piegeler T, Roessler B, Goliasch G, Fischer H, Schlaepfer M, Lang S, Ruetzler K. Resuscitation 2016 May;102:70-4

Randomised human cadaver study comparing Laryngeal Tube, EasyTube, LMA Classic, i-gel, ETI and BVM effect on protection against regurgitation and aspiration during CPR. Five minutes of CPR was administered according to 2010 European Resuscitation Council Guidelines. Aspiration was detected in two out of five cadavers with i-gel, while none were recorded when using ETI. Study provides experimental evidence that ETI offers superior protection during CPR.

Case series: protection from aspiration and failure of protection from aspiration with the i-gel® airway

Gibbison B, Cook TM, Seller C. Br J Anaesth 2008; 100(3): 415-417

Regurgitation of gastric contents was seen in three low-risk patients during anaesthesia. In two patients where only low volumes of gastric fluid were seen flowing from the i-gel®, there was no sign of aspiration. An 85kg male patient regurgitated large amounts of liquid, and although this was mostly expelled from the i-gel®’s gastric channel there were signs of minor aspiration. The i-gel® allowed early identification of regurgitation in these cases.
