Randomized Comparative Study Between Classic Laryngeal Mask Airway and I Gel Airway in Obese Patients Having BMI 35-40 During Elective Non Abdominal Surgery.

The aim of this study is to compare between cLMA and I gel regarding insertion success rate, the time of insertion, leaking pressure, assessment of position by fiber optic, hemodynamic, Spo2 for each device during insertion and maintenance of general anaesthesia and postoperative complications in obese patients

I gel is a new type of laryngeal mask and doesn't have an inflatable cuff. Because of its thermoplastic elastomer structure, it exactly adapts to the supraglottic tissue by binding with body temperature, thus minimising air leakage
