i-gel® from Intersurgical: clinical evidence listing

Corso RM, Battelli D, Maitan S, Zampone S, Agnoletti V. J Anaesthesiol Clin Pharmacol. 2014 Apr;30(2):288-90

Database review of 45 patient records meeting authors' set criteria, which included i-gel sizes 1-2.5. i-gel use in MRI produces no artefacts and the authors conclude the device is a useful device in this scenario, offering quick insertion time and low rate of complications.

54 infants were allocated with success rate at first attempt and fibreoptic views measured. First-attempt success was 100% for i-gel, compared to 69 in LMA.

Airway sealing ability, success rate of insertion and adverse events were among the recorded outcomes in this study. Leak pressures and insertion success rates are similar between the two devices, however the i-gel slid out of the mouth of a small amount of patients in this scenario. Authors recommend the device should be secured more tightly.

Total of 170 children were assigned to either the i-gel® or LMA Supreme®, with leak pressure the primary outcome measured. Secondary evaluations included insertion time, insertion success rate, fibreoptic view and complications, to name a few. Resulting median leak pressure was higher with i-gel® and the authors conclude it could be a ‘useful alternative to the Supreme®’.

In this survey distributed to the members of APAGBI, the current usage of supraglottic airway devices in routine practice and difficult airways in the UK was assessed. Of the 244 members, 88% preferred the use of first-generation devices, with the most important design feature being the availability of a complete range of sizes. 77% would like to see more randomised controlled trials on SAD safety in children.
