Clinical Trial Summary

The purpose of this study is to identify patient and provider-chosen factors that put patients at risk for the development of hypoxemia (oxygen saturation < 90% for 5 seconds) during endoscopy and to use this knowledge to develop a treatment protocol for specific causes of hypoxemia in adult esophagogastroduodenoscopy outpatients.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of laryngospasm during EGDs	Determine if prophylactic suctioning after sedation but prior to introduction of endoscope changes the incidence of laryngospasm during EGDs.	2 hours
Primary	Identify risk factors for the development of hypoxemia during EGD	These risk factors include both patient factors (ASA class, history of cardiopulmonary disease, BMI, social history, Obstructive Sleep Apnea, STOP-BANG scores and age) and provider-chosen factors (medications given, airway interventions, percent and flow of oxygen in liters per minute, and whether or not the patient was suctioned prior to or during the procedure).	2 hours
Secondary	Incidence of copious secretions, choking, desaturation, and shortened or aborted procedures	Determine if prophylactic suctioning after sedation but prior to introduction of endoscope changes the incidence of copious secretions, choking, desaturation, and shortened or aborted procedures.	2 hours
Secondary	Identify the various causes of hypoxemia during EGD	These risk include apnea, hypoventilation, laryngospasm, or other cause of airway obstruction	2 hours
