Comparison of I-gel and I-gel Plus in Elderly Patients

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.
