- Al-Balqa Applied University
- Brief 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.
- Detailed Description
Patients of both genders, aged between 18 and 85 years old and referred to standard upper endoscopy at Luzmila Hospital will be included in the study. Patients who are pregnant, have known allergies to the drugs used or a history of sedation-related complications (i.e., severe paradoxical response, hypoxemia, bradycardia, and hypotension) or gastrectomy, are American Society of Anesthesiologist (ASA) class ≥ IV (11), or are unable to provide informed consent will be excluded from participating in the study. The patients undergoing a standard upper endoscopy will be randomly assigned to either continuous infusion (CI group) of propofol (Diprivan) with induction using benzodiazepine (2 mg Dormicum i.v.) or only intermittent bolus injection (BI group) of propofol (Diprivan) infused by an anesthesiologist. BI was defined by intermittent use of 20 mg propofol (Diprivan) boluses on demand, with a minimum period of 30 seconds between boluses to evaluate the effect of the drug. CI was defined by continuous propofol (Diprivan) infusion at a 3 mg/ kg/h rate.
The anesthesiologist will follow up the patient during the first observation period, the average time spent in the recovery area and register the requied data during the procedure using Aldrete score (a post anesthesia recovery score where a minimum score of 8 is required for discharge).
The patients' identities will be coded and the data will be kept confidential. The study protocol will be performed according to the Decalrations of Helsinki and will be applied for approval by the Institutional Review Board at Al-Balqa Applied University. Written informed consent was obtained from all patients.

Group Intervention Description Continuous infusion (CI group) of propofol Propofol 100 MG in 10 ML Injection CI was defined by continuous propofol infusion at a 3 mg/ kg/h rate with induction using benzodiazepine (2 mg dormicum i.v.) to evaluate the effect of the drug and assess sedation induction time, total dose of propofol, recovery time, quality of sedation. Intermittent bolus injection (BI group) of propofol Propofol 100 MG in 10 ML Injection BI was defined by intermittent use of 20 mg propofol boluses on demand, with a minimum period of 30 seconds between boluses to evaluate the effect of the drug and assess sedation induction time, total dose of propofol, recovery time, quality of sedation.
- Primary Outcome Measures
Name Time Method Sedation induction time (minutes) 30 minutes Sedation induction time (minutes) is the time measured from the deep sedation induction until the patient is deeply sedated
Total dose of propofol (mg) 30 minutes Total dose of propofol (mg) used during the upper endoscopy procedure
Recovery time (minutes) 30 minutes Recovery time (minutes) is the time used for the patients to open their eyes after stoping sedation
- Secondary Outcome Measures
Name Time Method Involuntary movement 30 minutes Any involuntary patient movement during the endoscopy procedure under deep sedation
Adverse events 30 minutes Any adverse events occurring during the procedure such as apnea, dyspnea, hiccups, jerky movements...etc
Quality of sedation 30 minutes How deeply is the patient sedated (VAS) as assessed by the endoscopist (1 good, 2 moderate, 3 poor)
