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.
