Official title

A Prospective, Randomized Trial Comparing the Use of High Flow Nasal Cannula, Standard Face Mask and Standard Nasal Cannula in Morbidly Obese Patients With High Risk of Obstructive Sleep Apnea Undergoing Colonoscopy

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

It is standard practice in the United States and many parts of world to perform Gastrointestinal endoscopy with the patient under deep intravenous sedation. Obesity is accepted as a patient specific risk factor for hypoxic events during procedural sedation for GI endoscopic procedures. The obese population has a higher prevalence of obstructive sleep apnea (OSA), which is characterized by repeated obstruction of the upper airway, and leads to apnea and desaturation. This prospective, randomized study was designed to compare the effectiveness of the high flow nasal cannula, standard nasal cannula and standard face mask in morbidly obese patients with a high risk of sleep apnea, (BMI greater than 40, STOPBANG greater or equal to 5) receiving deep intravenous sedation during colonoscopies. This study will assess which method leads to a lower incidence of intraoperative desaturation events compared to the current standard of care.
