i-gel® from Intersurgical: clinical evidence listing

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

Application of PEEP using the i-gel during volume-controlled ventilation in anesthetized, paralyzed patients.

Kim YB, Chang YJ, Jung WS, Byen SH, Jo YY. J Anesth. 2013 Dec;27(6):827-31

After placement of an i-gel device in 40 patients, 20 were ventilated without PEEP while the other half received 5cmH20. Incidences of significent leaks and leak volumes were similar in both groups.

Initial experience of the i-gel® supraglottic airway by the residents in pediatric patients

Abukawa Y, Hiroki K, Ozaki M. J Anesth. 2012; 26(3): 357- 61.

This study investigated the use of paediatric i-gel® by residents on a total of 70 children of ASA score I-II undergoing surgery, split into three groups. Group 1: size 1.5; group 2: size 2; group 3: size 2.5. Seven characteristics were evaluated, including ease of i-gel® and gastric tube insertion, leak pressure and hypoxia rate. Overall insertion success rate and first-attempt success rate were 99% and 94% respectively, with gastric tube instertions easy in all cases. Results show that the i-gel® is a safe and effective device for use by residents with limited experience of paediatric airway devices. The authors warn that special attention should be given when using size 1.5 that the airway is protected.

A randomized comparison of the i-gel and the ProSeal laryngeal mask airway in pediatric patients: performance and fiberoptic findings

Fukuhara A, Okutani R, Oda Y. J Anesth. 2012; 27(1): 1-6

A prospective, randomised and controlled test of 134 children, aged three months to 15 years old, undergoing general anaesthesia were inserted with either i-gel® size 1.5-3 or ProSealTM equivalent to gauge insertion performance. Outcome variables included leak pressure, ease of insertion, success rate and fibreoptic view. Most outcomes were very similar, however fibreoptic view was significantly better with i-gel®.
