What this study is about

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.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Full registry criteria

Inclusion Criteria: * Age ≥ 18 years * Patients scheduled to undergo ≥ 4 electroconvulsive therapy (ECT) sessions * Body mass index (BMI) ≥ 30 kg/m² (WHO obesity classification) * American Society of Anesthesiologists (ASA) physical status class I to III * Provided written informed consent (by patient or legal guardian) Exclusion Criteria: * Patients under 18 years of age * Patients with ASA class IV or V * Patients with anticipated dental injury risk that precludes use of a laryngeal mask airway * Patients or guardians who refuse participation

Treatments and study arms

Laryngeal Mask Airway

Device

A supraglottic airway device (i-gel) used to deliver oxygen and assist ventilation during electroconvulsive therapy (ECT) in obese patients. The device is inserted after induction of general anesthesia and removed after spontaneous respiration is restored.

High-Flow Nasal Cannula

Device

A heated and humidified oxygen delivery system that provides high flow oxygen through nasal prongs. In this study, it is used throughout the ECT procedure to maintain oxygenation in obese patients without the need for invasive airway insertion.

Primary outcomes
