Study of a Modified Supraglottic Airway Device Allowing Easy Switch Between Supraglottic and Endotracheal Ventilation During General Anesthesia

What this Trial Is About

Researchers are evaluating a new modification to the supraglottic airway SGA device designed to improve airway management during general anesthesia. This modified device, called the AZ modification, features an opening that allows an endotracheal tube ETT to be inserted through the SGA body without needing an exchange catheter. This innovation aims to enable easy conversion between supraglottic and endotracheal ventilation modes during surgery, addressing complications related to airway management, ventilation therapy, hypoxia, and hypoventilation. The study involves patients undergoing general anesthesia who require airway management for ventilation. Participants will receive the AZ modified supraglottic airway device, which can be converted reversibly to endotracheal ventilation by replacing a special adapter piece with an ETT. This device modification has been professionally manufactured and tested for feasibility on manikins before clinical trial use. The intervention focuses on how well the device supports oxygenation and ventilation and how successfully it allows switching between ventilation modes during and immediately after use. During the study, participants will receive airway management with the AZ modified device while under general anesthesia for surgical procedures. Researchers will measure the rate of successful oxygenation and ventilation, as well as the ease of converting between supraglottic and endotracheal ventilation. These outcomes will be assessed during and immediately after the intervention. The trial excludes patients with anticipated airway difficulties or other factors that could affect airway management. Participation lasts through the anesthesia procedure and immediate recovery period to evaluate device performance and safety.
