Abstract

There are numerous studies in the literature of anesthesia administered during colonoscopy including various methods, drugs, and monitoring systems; however, none of them has studied whether a university-degreed nurse anesthesia provider (known as a certified registered nurse anesthetist in the United States) is skillful enough to provide safe anesthesia in patients undergoing endoscopic procedures. The aim of our study was to determine whether anesthesia provided by a university-degreed nurse anesthesia provider during an endoscopic procedure is comparable in terms of safety and efficacy with routine sedation practice. This randomized, double-blind study included 100 adult patients who underwent colonoscopy conducted in the Evgenidion University Hospital during a single year. Subjects were divided into 2 groups: the first group received the usual scheme of intravenous sedation with midazolam and fentanyl administered by a member of the endoscopic team that was blind to Bispectral Index (BIS) values recordings (Group 0). The second group received intravenous bolus injection of propofol bolus by a university-degreed anesthesia registered nurse based on the BIS values (Group 1). The average of the mean BIS values of Group 0 was 85.07 (SD = 8.01) and for Group 1 was 76.1 (SD = 10.88; p = .04). The parameters of "patient memory during procedure" and the satisfaction scores (as self-assessed by the patients as well as 2 gastroenterologists) were also significantly different between the patients of the 2 groups (p = .000). Comparison between the 2 groups showed that the sedation offered by a university-degreed nurse anesthesia provider was absolutely safe and effective, offering particular comfort to the patient during the intervention and contributing significantly to its successful results.
