End-Tidal Carbon Dioxide Monitoring Device for Sedation During Endoscopic Ultrasonography

Not Applicable
Conditions
Endoscopic Ultrasonography
Monitoring
Sedation
Interventions
Device: SpO2 and respiratory motion monitoring
Device: Novel end-tidal CO2 monitoring device
Registration Number
NCT04549623
Lead Sponsor
Changhai Hospital
Brief Summary

To meet the needs of both operators and patients, moderate and deep sedation has been widely used in digestive endoscopy, which is invasive and painful. With its pleasant effects, sedation has complications nevertheless. And respiratory depression is the most common one, which makes respiratory monitoring significant. SpO2 and respiratory motion are regularly monitored without satisfying timeliness or sensitivity. Capnography with current device is only able to detect either oral or nasal breathing. The present study was designed to test the effect of the investigator's modified End-Tidal Carbon Dioxide (ETCO2) monitoring device for sedation during endoscopic ultrasonography-guided fine needle aspiration.

Primary Outcome Measures
NameTimeMethod
Peripheral oxygen saturationAcross the sedation, assessed up to 2 hours

Peripheral oxygen saturation is measured by pulse oximetry and hypoxemia is defined as SpO2≤91%

Secondary Outcome Measures
NameTimeMethod
Arterial pO2 and pCO230 minutes after initiation of the sedation

The results of arterial blood gas measurements including partial pressure of oxygen (pO₂) and carbon dioxide (pCO₂)

Incidence of hypertension and hypotensionFrom the completion of sedation to the completion of endosonography procedure, assessed up to 2 hours

Hypertension or hypotension is defined as an increase or decrease in systolic blood pressure ≥20% compared to baseline values

Total dosage of propofolAcross the sedation, assessed up to 2 hours

The patients are induced with 1.5\~2.5mg/kg and maintained with 6\~10mg/(kg•h) propofol. A propofol bolus dose range 0.2\~0.5 mg/kg will be administered when needed.

The numbers of the times of body movementFrom the completion of sedation to the completion of endosonography procedure, assessed up to 2 hours

The numbers of the times of any body movement across the procedure

Recovery timeAfter termination of the sedation medication, assessed up to 2 hours

Duration of the recovery from sedation

Satisfaction score of the patients and endosonographersAcross the procedure, assessed up to 2 hours

Satisfaction score of the patients and endosonographers regarding to the sedation quality measured by a 0-100 visual analogue scale (VAS). 100 refers to the highest satisfaction degree while 0 refers to the worst satisfaction degree.
