I-gel Plus Comparison Study
Sponsor: Dongguk University International Hospital
Summary
This study compares the airway sealing pressure between I-gel® and I-gel plus® in elderly patients (aged 65-85) undergoing general anesthesia. I-gel® is a supraglottic airway device with a non-inflatable cuff, and I-gel plus® is an improved version with a larger gastric drainage channel, enhanced airway tube, and longer cuff tip for better sealing. The study aims to evaluate differences in sealing pressure and other performance metrics in this population, where anatomical changes may affect device efficacy.

Interventions
I-gel first
After general anesthesia, I-gel is inserted first, the maximum sealing pressure is measured, and then it is removed. Subsequently, I-gel plus is inserted, and the same procedure is repeated.

common
Prior to general anesthesia, as a common baseline procedure for all study arms, the patient's Charlson Comorbidity Index and frailty score are assessed and recorded through patient evaluation (using the Clinical Frailty Scale for the frailty score). Immediately before induction of anesthesia, progressive pressures (100 g, 200 g, 300 g, 400 g, and 500 g) are applied to the patient's thyroid cartilage, and the degree of deviation is measured and documented.
