i-gel® from Intersurgical: clinical evidence listing

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

Higher insertion success with the i-gel supraglottic airway in out-of-hospital cardiac arrest: a randomised controlled trial

Middleton PM, Simpson PM, Thomas RE, Bendall JC. Resuscitation 2014;85(7):893-7

Subjects with out-of-hospital cardiac arrest were allocated to either the i-gel or Portex Soft Seal laryngeal mask group, within a large Australian ambulance group. Primary outcome was successful insertion of the airway. The i-gel had a significantly higher success rate than Portex Soft Seal and significantly lower median ease of insertion scores.

Evaluation of a new supraglottic airway device in ambulatory surgery: the I-gel

Jaoua H, Djaziri L, Bousselmi J, Belhouane H, Skander R, Ben Maamer A, Cherif A, Ben Fadhel K. Tunis Med. 2014 Apr;92(4):239-44

100 patients scheduled for short duration elective surgery were included, with ease of insertion, leak fraction, gastric leak, complications and ease of insertion among the parameters measured. Success rate of insertion was 99%, with first-attempt success at 92%. Authors conclude that the I-gel can be used 'safely and effectively'.

A randomised comparison of the i-gel™ and the Laryngeal Mask Airway Classic™ in infants

Kim MS, Oh JT, Min JY, Lee KH, Lee JR. Anaesthesia. 2014 Apr;69(4):362-7

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.

A randomised crossover comparison of manikin ventilation through Soft Seal®, i-gelTM and AuraOnceTM supraglottic airway devices by surf lifeguards

Adelborg K, Al-Mashhadi RH, Nielsen LH, Dalgas C, Mortensen MB and Løfgren B. Anaesthesia. 2014 Apr; 69(4): 343-7

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®’.
