Study Comparing I-gel and Protector Supraglottic Airway Devices for Adults Under General Anesthesia

What this Trial Is About

Researchers are evaluating the learning curves of two different laryngeal mask airway LMA devices, the I-gel and the Protector, by comparing how anesthesiology residents place them in adult patients. The study focuses on airway management during general anesthesia and aims to understand the time and ease of device placement. Adults participating in the study will be randomly assigned to receive either the LMA Igel or LMA Protector device during surgery. The devices will be inserted intraoperatively while patients are under general anesthesia. Placement attempts will be timed from when the clinician picks up the device until the first capnography waveform appears, with up to three attempts allowed per patient. Participants will be closely monitored during the placement attempts, with documentation of any adverse events occurring during this time. The primary measure is the time required for successful placement. The study includes adult patients aged 18 to 90 years with specific health and anatomical criteria, and participation involves monitoring during surgery. The study is expected to conclude by September 2025.
