Improve Oxygenation and Capnographic Detection During Sedative EGD

Apnea, Obstructive Clinical Trial

Official title:
Comparison of Techniques to Improve Oxygenation and Capnographic Detection During Sedative Gastrointestinal Endoscopy

Clinical Trial Summary

The purpose of this study is to compare the effect of mandibular advancement bite block and high flow nasal cannula to standard bite block for oxygenation, capnographic measurement, prevention of hypoxemia, intervention events and adverse effects during endoscopic examinations.

Clinical Trial Description

During endoscopic examinations, especially during those performed via oral insertion of endoscopes, an oral bite is used to protect the examination instruments and patients. During sedated endoscopic examinations, the patients are under influence of anesthetics. Upper airway obstruction often occurred due to respiratory depression and airway collapse resulting in desaturation. Airway management with high percentage oxygen, jaw thrust, or insertion of nasal airways by trained anesthetic personnel is required during upper airway obstruction emergencies. Nasal airway is invasive and causes nasal bleeding, sinusitis and other problems. Jaw thrust and bag-mask ventilation requires training and is a burden to anesthetic personnel to perform. Oxygenation and capnography are important ventilatory monitors during sedative procedures. These are often influenced by open mouth breathing during upper gastrointestinal endoscopic examinations making oxygenation and capnographic measurements unreliable. In this study, we group the patients into A group using standard of care, B group using mandibular advancement oral bite and C group using high-flow nasal cannulas. After anesthetic induction, gastric endoscopy will be performed. Oxygenation, end-tidal carbon dioxide, and degree of upper airway obstruction will be evaluated and recorded. Differences between the groups will be evaluated. ;
