Comparing I-gel and Classic Laryngeal Mask Airway Use in Different Head Positions for Patients Over 75 Undergoing Urological Surgery

What this Trial Is About

Researchers are evaluating the insertion success of two supraglottic airway devices, the classic Laryngeal Mask Airway LMA and the i-gel, in elderly patients over 75 years old undergoing elective urological surgery under general anesthesia. The study aims to compare these devices when used in different head and neck positions to provide guidance on the best airway management approach for older adults. The trial is a prospective, randomized, double-blind clinical study involving 120 patients with ASA physical status I-III. Participants will be randomly assigned to one of four groups standard head position with i-gel, right lateral head rotation with i-gel, standard head position with classic LMA, or right lateral head rotation with classic LMA. The interventions include the use of the two airway devices in either a standard or rotated head position during surgery. The study will assess how easily and quickly the devices can be inserted in these positions. During the study, researchers will measure insertion time, number of attempts needed for placement, ease of insertion, hemodynamic responses, oropharyngeal leak pressures, fiberoptic scores, and any airway-related complications. These assessments will help determine which device and head position combination works best for airway management in elderly patients. The total duration of participation depends on the surgical procedure and anesthesia period.
