Intermittent Boluses Versus Infusion of Propofol During Gastroscopy

Sedation induction time (minutes),Total dose of propofol (mg),Recovery time (minutes)

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.
