Evaluation of the Insertion of I-gel and Classic LMA in Different Head Positions in Elderly Patients

This prospective, randomized, double-blind clinical study aims to evaluate the insertion success of two supraglottic airway devices, the classic Laryngeal Mask Airway (LMA) and the I-gel, in different head and neck positions in elderly patients undergoing elective urological surgery under general anesthesia. A total of 120 patients aged over 75 years with ASA physical status I-III will be randomly assigned to one of four groups: standard position with I-gel, right lateral rotation with I-gel, standard position with classic LMA, and right lateral rotation with classic LMA. The study will compare insertion time, ease and success of placement, number of attempts, hemodynamic responses, oropharyngeal leak pressures, fiberoptic scores, and airway-related complications. The findings aim to provide clinical guidance on the optimal use of supraglottic airway devices in geriatric patients in various head positions.
