Background:The aim of this study was to evaluate the safety and efficacy of sevoflurane-based sedation technique for colonoscopy in geriatric patients as compared with that using propofol.Materials and Methods:Sixty elderly patients, who were scheduled for colonoscopy, participated in this controlled prospective study and were randomly allocated into two groups; P and S. The patients were sedated using either propofol in P group or sevoflurane in S group. Complications (including apnea, the need for airway intervention, occurrence of general anesthesia [GA], hemodynamic instability and others), the fentanyl requirement and the times of the procedure, recovery, and discharge were recorded in both groups.Results:The patients in P group had more frequent apnea attacks, need for airway intervention and occurrence of GA compared to the patients in S group. However, both groups were comparable regarding the other measured variables.Conclusion:For geriatric colonoscopy, sevoflurane can provide safe and effective sedation alternative to propofol.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
