Intermittent Boluses Versus Infusion of Propofol During Gastroscopy

Summary

It is unclear whether continuous infusion or intermittent bolus injection of propofol is better for achieving adequate sedation during a standard upper endoscopy. The study aimed to compare the efficacy and safety of continuous infusion and intermittent bolus injection of Propofol (Diprivan) during a standard upper endoscopy. In this prospective study, patients will be randomly assigned to undergo a standard upper endoscopy with either continuous infusion (CI group) or intermittent bolus injection (BI group) of Propofol (Diprivan) administered by an anesthesiologist. The primary outcome will be to assess the quality of sedation by the endoscopist (VAS). In addition to other sedation-related parameters that will include sedation induction time (minutes), total dose of propofol (mg), recovery time (minutes) using Aldrete score, any involuntary patient movement, and adverse events.
