Comparing two operators versus one for GlideScope intubation

A Two-Operator Technique for GlideScope-Assisted Endotracheal Intubation: Does It Yield a Similar Success Rate? A Randomized Controlled Trial

Not applicable Interventional American University of Beirut Medical Center · NCT06727513

This study is testing if using two operators instead of one for GlideScope intubation can help adults have a better and safer experience during the procedure.

What this trial studies

This study aims to evaluate the effectiveness of a two-operator technique for GlideScope-assisted endotracheal intubation compared to a single-operator approach. It will assess the first attempt success rate, time to intubate, and the occurrence of adverse events such as airway trauma and oxyhemoglobin desaturation. A total of 428 adult patients will be enrolled and randomly assigned to either the single or double operator group, with stratification based on predictors of difficult intubation. The study seeks to determine if the two-operator method improves outcomes in difficult intubation scenarios.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older, classified as ASA Class I to III, undergoing elective procedures requiring orotracheal intubation.

Not a fit: Patients with ASA Class IV or V, those requiring emergency procedures, or those with specific airway pathologies will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the success rate of intubation in patients with difficult airways, leading to safer anesthesia practices.

How similar studies have performed: While the two-operator technique is a novel approach in this context, similar studies have shown promising results in improving intubation success rates.
