title: Oxygen saturation post-gastroscopy and post-colonoscopy.
abstract: A standard of care for providing pulse oximetry monitoring for patients receiving conscious sedation during and after endoscopy has not been established. This study sought to clarify whether desaturation occurs after gastroscopy and colonoscopy and what characteristics are predictive of desaturation that does occur. The convenience sample consisted of 475 adult participants receiving meperidine and/or midazolam in a hospital-based outpatient setting. A baseline oxygen saturation level was obtained before the procedure. Assessment of the oxygen saturation continued in the recovery room for 1 hour, with readings recorded every 10 minutes. A saturation of 90% or less was used as the indicator to resume oxygen therapy. Data revealed that oxygen desaturation in the recovery phase is influenced by the preprocedure baseline oxygen saturation level, smoking history, and age. The incidence of oxygen desaturation was 24% in the recovery phase, with the majority of decreases occurring within the first 10 minutes.
