i-gel® from Intersurgical: clinical evidence listing

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

A new single use supraglottic airway with a non-inflatable cuff and an esophageal vent: An observational study of the i-gel®

Richez B, Saltel L, Banchereau F, Torrielli R, Cros AM. Anesth Analg. 2008; 106(4): 1137-9

This study on 71 ASA I-II women scheduled for gynaecological surgery, reported a 97% insertion success rate with i-gel®. Mean seal pressure was 30cm H2O. A gastric tube was inserted in 100% of cases. Only one case of coughing and sore throat occurred. The authors concluded that ‘the i-gel® is a reliable, easily inserted airway device that provides an adequate seal with a low morbidity rate.’

Nerve damage following the use of an i-gel® supraglottic airway device

Theron AD, Loyden C. Anaesthesia 2008; 63(4): 441-442

This article describes a post-operative complication after i-gel® use. The patient was successfully ventilated with a size four i-gel®, which was in line with the recommendation for the patient’s weight (85kg). After surgery, the patient reported numbness in the lower lip. An examination shows swelling and an ulcer on the inside of the lip. There are two possible explanations for this injury – the patient’s lip may have been caught in the tape used to secure the i-gel® or it may have been caught in between the i-gel® and the patient’s teeth. The authors warn that this could occur with any airway device, but that extra care should be taken with the i-gel® due to the bulkier design.
