Summary

This study will compare two methods—the El Ganzouri Risk Index and airway ultrasound—to predict difficult intubation in 52 adults undergoing bariatric surgery. Researchers will measure how well each method identifies patients who may have trouble with breathing tube placement. The goal is to improve safety and planning for these surgeries.

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 study could lead to better preoperative tools to predict difficult intubation, potentially reducing complications in bariatric surgery.
What could go wrong
This is a small observational study with only 52 participants, so results may not apply to all patients. It does not test a new treatment or intervention.
