Which airway method keeps oxygen levels safer during hysteroscopy sedation?
NCT ID NCT05701839
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looked at 400 women undergoing hysteroscopy under deep sedation to compare two airway methods: a face mask and a nasopharyngeal tube. The goal was to see which method better prevents low oxygen levels, using a new monitoring tool called oxygen reserve index. The findings could help improve safety during this common procedure.

- Active substance
- face mask ventilation and nasopharyngeal tube ventilation
- What this could lead to
- If successful, this could help doctors choose the best airway method to prevent low oxygen levels during deep sedation for hysteroscopy.
- What could go wrong
- This is a completed study with 400 participants, but it focuses on a specific procedure and may not apply to other types of surgery or sedation.
