What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Summary

This study is testing a new video-based scale (called VCI) to help doctors predict when placing a breathing tube during surgery might be difficult. Researchers in Spain will enroll 1,500 adults having planned surgery and compare ratings from the person doing the intubation and an outside observer. The goal is to see if the VCI scale is a reliable way to identify challenging airways.

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 successful, this could give doctors a simple video tool to better predict difficult intubation before surgery.
What could go wrong
This is an early observational study, not a treatment trial. The scale may not prove more accurate than current methods, and results may not apply outside Spain.

This is an AI summary of the original study and may miss details. Read our disclaimer.
