The Effect of Two Different Airway Management on Oxygenation During Deep Sedation in Patients Undergoing Hysteroscopy, Based on Oxygen Reserve Index Monitoring

First Affiliated Hospital Xi'an Jiaotong University·interventional·Posted Jan 27, 2023·Updated May 8, 2026

In Brief

A clinical study evaluating face mask ventilation, nasopharyngeal tube ventilation, and 2 other interventions for Deep Sedation. Completed, enrolled 400 participants across 1 site.

Detailed Summary

Hysteroscopy is used to examine and treat uterine diseases. Because of severe pain due to uterine distention and cervical dilatation, deep sedation usually be provided during this procedure. Respiratory depression and upper airway obstruction are main respiratory complications during deep sedation. Face mask and nasopharyngeal airway are main airway management during deep sedation. Oxygen reserve index is a non-invasive parameter, it reflects the moderate hyperoxia statues. In this study, investigators compare the effect of face mask and nasopharyngeal airway management on oxygenation during deep sedation in participants undergoing hysteroscopy. Investigators also investigate whether oxygen reserve index monitoring reduce the incidence of hypoxemia.

Interventions

face mask ventilationprocedure

In participants with face mask ventilation, oxygen inhaled through face mask at a flow rate of 5 L/min.

nasopharyngeal tube ventilationprocedure

In participants with nasopharyngeal tube ventilation, oxygen inhaled through face mask before induction and through nasopharyngeal tube after consciousness disappear at a flow rate of 5 L/min.

oxygen saturation monitoringdevice

In participants with oxygen saturation monitoring, assist ventilation through face mask will be performed when oxygen saturation drops to 95%, it lasts for another 10 seconds when oxygen saturation restores to 100%.

oxygen reserve index monitoringdevice

In participants with oxygen reserve index monitoring, assist ventilation through face mask will be performed when oxygen reserve index drops to 0.1, it lasts for another 10 seconds when oxygen reserve index restores to 0.1.
