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.
