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.

Conditions

  • Deep Sedation

Interventions

DEVICE

oxygen reserve index monitoring

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.

DEVICE

oxygen saturation monitoring

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%.

PROCEDURE

face mask ventilation

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

PROCEDURE

nasopharyngeal tube ventilation

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.
