Patients who will undergo induction of general anesthesia with muscle relaxants in the regular medical care at Hamamatsu University Hospital between August 2024 and March 2026.
Patients who meet any of the following criteria are not eligible for this study
- Patients for whom intubation is clinically indicated due to severe obesity or severely compromised respiratory function.
- Patients in whom the administration of muscle relaxants is inappropriate or unnecessary for the performance of general anesthesia or surgery.
- Patients for whom induction of anesthesia with intravenous anesthetics (propofol or midazolam) is considered inappropriate.

- Primary Outcome Measures
Name Time Method i-gel information size, insertion time, number of insertions, insertion status index, and number of size changes
Leak pressure, expiratory volume, and glottal findings during ventilation Leak pressure, expiratory volume, and glottal findings during ventilation (see figure below)
Information after i-gel extubation after i-gel extubation blood adherence, postoperative hoarseness, postoperative dysphagia, postoperative dysphonia, and intubation transition
Background of the subject age, gender, smoking history, lung disease history, sleep apnea history, cervical spine lesion history, respiratory status interview including presence or absence of snoring, and surgical procedure
Physical examination Height, weight, dental condition, and head and neck condition, including degree of aperture
Clinical examination within the scope of the preoperative examination pulmonary function tests (lung capacity, rate per second), biochemical tests (AST (GOT), ALT (GPT), LDH, ALP, cholinesterase, LAP, gamma-GTP, amylase, BNP, urea nitrogen, creatinine, CRP)
- Secondary Outcome Measures
Name Time Method leak pressure Assess leak pressure during ventilation in the supine position with the i-gel and i-gel plus.
expiratory volume Assess expiratory volume during ventilation in the supine position with the i-gel and i-gel plus.
glottal findings Assess glottal findings during ventilation in the supine position with the i-gel and i-gel plus.
