About this trial
This study aims to compare two oxygenation strategies-laryngeal mask airway (LMA) ventilation and high-flow nasal cannula (HFNC)-during electroconvulsive therapy (ECT) in obese patients. Due to their physiological characteristics, obese patients are at increased risk of hypoxia during ECT under general anesthesia.
Adult patients with a body mass index (BMI) ≥30 who are scheduled to undergo ECT will participate. Each participant will receive both oxygenation strategies in a fixed alternating order during four consecutive ECT sessions. The procedures will follow standard anesthesia protocols.
During the ECT procedures and the 30-minute recovery period in the post-anesthesia care unit, we will monitor the occurrence of hypoxia (SpO₂ \<92%), ventilator parameters, vital signs, postoperative confusion within 24 hours, and any reports of dental discomfort. This information will help assess the safety and clinical utility of each oxygenation method for obese patients receiving ECT.
