The Prediction Model of Hypoxemia for Safe Bronchoscopy

• Conditions: Hypoxemia; Obstructive Sleep Apnea

• Registration Number: NCT01370993
• Lead Sponsor: Seoul National University Bundang Hospital

Brief Summary

The purpose of this study is to develop the hypoxemia prediction model during fiberoptic bronchoscopy under MAC(monitored anesthesia care) anesthesia.

Detailed Description

Currently, diverse sedatives and analgesic methods are used during fiberoptic bronchoscopy for reducing patients' discomfort and facilities of procedures as British Thoracic Society recommendation. MAC anesthesia, one of the widely used sedative method during bronchoscopy, have many advantages, occurrence of respiratory depression, hypoxemia are not uncommon during the procedures. The investigators try to find out risk factors and develop the prediction model for hypoxemia during bronchoscopy under MAC anesthesia.

Primary Outcome Measures

Name	Time	Method
Lowest oxygen saturation during bronchoscopy, development of hypoxemia(SpO2<90%) during bronchoscopy	during the fiberoptic bronchoscopy, estimated procedure time is about 15min

Secondary Outcome Measures

Name	Time	Method
Need for oxygen flow increment	during the fiberoptic bronchoscopy, estimated procedure time is about 15min
the proportion of subjects who is require of mandible lift	during the fiberoptic bronchoscopy, estimated procedure time is about 15min
time delay for procedure due to hypoxemia	during the fiberoptic bronchoscopy, estimated procedure time is about 15min
the proportion of subjects with snoring	during the fiberoptic bronchoscopy, estimated procedure time is about 15min	snoring
