“…In fact, the overall risk of complications after colonoscopy is higher when patients receive anesthesia services related to those who receive non-anesthesia sedation. [23][24][25] In a prospective cohort study, Wernli et al found that the use of anesthesia service was associated with a 13% increase in the risk of any complication within 30 days after colonoscopy (95% confidence interval [CI], 1.12-1.14) and was associated specifically with an increased risk of perforation (odds ratio [OR], 1.07; 95% CI, 1.00-1.15), hemorrhage (OR, 1.28; 95% CI, 1.27-1.30), abdominal pain (OR, 1.07; 95% CI, 1.05-1.08), complications secondary to anesthesia (OR, 1.15; 95% CI, 1.05-1.28), and stroke (OR, 1.04; 95% CI, 1.00-1.08). 24 Additionally, the use of anesthesia service was found to be associated with a higher risk of serious adverse events for American Society of Anesthesiology I, II, and III subjects undergoing EGD than those who received endoscopist-directed sedation.…”
