This prospective controlled study aimed to examine the clinical performance of the i-gel in both obese and non-obese patients. 32 patients were divided into two groups, group O (BMI >30 kg/m2) and group C (BMI between 18.5 and 29.9 kg/m2). A range of parameters were evaluated including OLP (primary outcome), leak fraction, time taken to insert the device, ease of insertion, fiberoptic glottis view and adverse events. Results have demonstrated that OLP was marginally higher in Group O in comparison to group C (but not statistically different). In regards to the other parameters and side effects, these were comparable in both groups. Therefore, the i-gel provides an effective tool for the airway management of both obese and non-obese patients.

Use of extraglottic airways in patients undergoing ambulatory laparoscopic surgery without the need for tracheal intubation

Suhitharan T, Teoh WH. Saudi J Anaesth. 2013 Oct;7(4):436-41

Ransomised control trial comparing LMA Supreme with i-gel in 70 patients, with leak pressure, insertion success rates and leak fractions among the outcomes measured. While no post-operative complications were reported with i-gel, three patients suffered mild sore throat and one had mucosal injury in the Supreme group. i-gel had a higher but 'clinically inconsequential' leak fraction.

Comparative study between i-gel®, a new supraglottic airway device, and classical laryngeal mask airway in anaesthetised spontaneously ventilated patients

Helmy AM, Atef HM, El-Taher EM, Henidak AM. Saudi J Anaesth 2010; 4(3): 131-136

This study compared the cLMA and i-gel® in 80 healthy adult patients. The patients were randomly assigned to two groups for insertion of one of the devices during surgery. Haemodynamic data, oxygen saturation and end-tidal CO2 were similar in both groups. Leak pressure was significantly higher with the i-gel®, which also had a shorter insertion time. Postoperative complications were generally comparable, however there was a higher incidence of nausea and vomiting in the cLMA group due to gastric insufflation.
