Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adult patients aged 18 and older with ASA I-II status undergoing minor urological procedures.

Probably not a fit

Patients with anatomical anomalies of the upper airway or a history of difficult intubation may not benefit from this study.

What this trial studies

This randomized comparative study evaluates the effectiveness and safety of two laryngeal mask airway devices, the iGel and the Protector, during minor urological procedures in adult patients under general anesthesia. Participants will be randomly assigned to receive either the iGel or the Protector device. The study aims to assess not only the performance of these devices but also any unwanted effects that may arise during the procedures. By comparing these two devices, the study seeks to determine which one provides better airway management in this specific surgical context.

Why it matters

Potential benefit: If successful, this study could enhance airway management techniques during minor urological procedures, leading to improved patient safety and outcomes.

How similar studies have gone: Other studies have shown varying success with similar airway device comparisons, but this specific comparison is novel.
