Safety of non-anesthesia provider administered propofol sedation in non-advanced gastrointestinal endoscopic procedures: A meta-analysis.

Abstract

Background/Aims:The aim of the study was to evaluate the safety of non-anesthesia provider (NAPP) administered propofol sedation in patients undergoing non-advanced gastrointestinal (GI) endoscopic procedures.Materials and Methods:Pubmed, Embase, Cochrane central register of controlled trials, Scopus, and Web of Science databases were searched for prospective observational trials involving non-advanced endoscopic procedures. From a total of 608 publications, 25 [colonoscopy (9), upper GI endoscopy (5), and combined procedures (11)] were identified to meet inclusion criteria and were analyzed. Data was analyzed for hypoxia rates, airway intervention rates, and airway complication rates.Results:A total of 137,087 patients were involved. A total of 2931 hypoxia episodes (defined as an oxygen saturation below 90%) were reported with a pooled hypoxia rate of 0.014 (95% CI being 0.008-0.023). Similarly, pooled airway intervention rates and pooled airway complication rates were 0.002 (95% CI being 0.006–0.001) and 0.001 (95% CI being 0.000–0.001), respectively.Conclusions:The rates of adverse events in patients undergoing non-advanced GI endoscopic procedures with NAPP sedation are extremely small. Similar data for anesthesia providers is not available. It is prudent for anesthesia providers to demonstrate their superiority in prospective randomized controlled trials, if they like to retain exclusive ownership over propofol sedation in patients undergoing GI endoscopy.
