Video vs. standard laryngoscope: which is better for trainee doctors?
NCT ID NCT06842082
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed trial compared two ways to place a breathing tube (intubation) in adults having surgery: the standard direct laryngoscope and a video laryngoscope. Over 1,000 patients were included, and anesthesia residents performed all intubations. The study aimed to see which method leads to more successful first attempts and fewer complications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If videolaryngoscopy proves better, it could become the standard teaching tool for new doctors, improving patient safety during intubation.
- What could go wrong
- This is a completed study, so results are already known. The comparison may show no meaningful difference, or benefits may not apply outside the operating room.
This is an AI summary of the original study and may miss details. Read our disclaimer.
