Comparing i-gel and classic LMA insertion in different head positions for people over 75
Official title: Evaluation of the Insertion of I-gel and Classic LMA in Different Head Positions in Elderly Patients
Run by Sultan Abdulhamid Han Training and Research Hospital, Istanbul, Turkey · NCT07027293 · Data updated 2026-11-12
This will test whether the i-gel or classic LMA is easier and faster to insert in different head positions for people over 75 having elective urological surgery under general anesthesia.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are people older than 75 with ASA physical status I-III scheduled for elective urological surgery who do not have a known or anticipated difficult airway and are eligible for a supraglottic airway.
✕Probably not a fit
Patients with known or expected difficult airways, contraindications to supraglottic devices, or those scheduled for endotracheal intubation are unlikely to benefit from the results.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This prospective, randomized, double-blind study will enroll 120 patients older than 75 years with ASA I-III and randomly assign them to four groups combining device (i-gel or classic LMA) and head position (standard or right lateral rotation). Clinicians will measure insertion time, ease and success of placement, number of attempts, hemodynamic responses, oropharyngeal leak pressures, fiberoptic view scores, and airway-related complications. The protocol compares performance of the two supraglottic devices across head positions to identify practical differences relevant to geriatric airway management. Results are intended to guide device selection and positioning for elderly patients undergoing general anesthesia.
Why it matters
Potential benefit: If successful, the study could identify the safer and more reliable device and head position to improve airway management and reduce complications in elderly surgical patients.
How similar studies have gone: Previous comparative studies often report faster insertion and higher leak pressures with i-gel versus classic LMA, but randomized data specifically in elderly patients across different head positions are limited.
