Modification of a supraglottic airway device for better ventilation

Structural Modification In Supraglottic Airway Device Enhances Exchange Between Supraglottic & Endotracheal Ventilation Modes

Not applicable Interventional The Cleveland Clinic · NCT04498598

This study tests a new design of a breathing device to see if it makes it easier for doctors to switch to a breathing tube during anesthesia for adult patients.

What this trial studies

This study evaluates a new design of a supraglottic airway device that allows for easier conversion to endotracheal ventilation without the need for an exchange catheter. The modified device features an opening that enables access to an endotracheal tube, facilitating smoother airway management during anesthesia. The feasibility of this modification has been previously tested on manikins, and this trial aims to assess its effectiveness in real clinical settings. The study will involve adult patients scheduled for general anesthesia procedures requiring endotracheal intubation.

Who should consider this trial

Good fit: Ideal candidates are adult patients scheduled for general anesthesia procedures that require endotracheal intubation.

Not a fit: Patients with a history of difficult airways or those requiring special equipment for airway management may not benefit from this study.

Why it matters

Potential benefit: If successful, this modification could enhance airway management during anesthesia, potentially reducing complications related to ventilation.

How similar studies have performed: While this approach is innovative, similar modifications in airway devices have shown promise in improving ventilation outcomes.
