i-gel® from Intersurgical: clinical evidence listing

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

The effect of i-gel® airway on intraocular pressure in pediatric patients who received sevoflurane or desflurane during strabismus surgery

Sahin A, Tüfek A, Cingü AK, Caça I, Tokgöz O, Balsak S. Pediatr Anesth 2012; 22(8): 772-775

47 children due for eye surgery were administered with sevoflurane or desflurane randomly for anaesthesia. Intraocular pressure was then measured prior to i-gel® insertion, at two and five minutes after insertion, and immediately after removal. Sustained pressure decrease present during procedure, but no significant difference between pre- and post-operative pressure.

LMA Supreme® vs i-gel®--a comparison of insertion success in novices

Ragazzi R, Finessi L, Farinelli I, Alvisi R, Volta CA. Anaesthesia 2012; 67(4): 384-8

Following a short lecture and manikin training, novice airway users were randomly selected to insert either the LMA Supreme® or i-gel® into 80 patients undergoing breast surgery, to measure insertion success rate and ventilation profile.

The i-gel™ - A promising airway device for magnetic resonance imaging suite

Taxak S, Bhardwaj M, Gopinath A. J Anaesth Clin Pharmacol 2012; 28(2): 263–264

Two successful cases of paediatric i-gel® used to manage the airway during brain MRI under general anaesthesia. The first, a three-month-old, was maintained using size one; whilst a size two was used on the second case, a boy aged three-and-a-half with a Mallampati score of two. Usual capnography readings taken to ensure secure placement, and in both cases there was no evidence of desaturation. Compared to other laryngeal mask airways, the authors conclude that i-gel® suffers no risk of displacement, meaning intubation does not have to be repeated on known sensitive patients. They also deduce that i-gel® has other advantages, including ease of insertion and minimum adverse effects on removal of the device. Large studies are required, however, to ‘confirm its usefulness’.
