Endoscopic Retrograde Cholangiopancreatography (ERCP) is a lengthy and uncomfortable procedure that requires adequate sedation. Propofol is the commonly used sedative during ERCP. However, dose dependent cardiac and respiratory depression may occur. Hypotension usually occurs in severe cholangitis which necessitate the use of alternative sedative. The aim is to study the efficacy and safety of ketofol as a sedative during urgent ERCP for severe cholangitis.
This randomized controlled trial was carried out on 96 patients undergoing urgent ERCP for severe cholangitis. Patients were allocated into two groups; group 1: received ketofol and group 2: received propofol. Demographic data, ERCP duration, recovery time, heart rate (HR), mean arterial pressure (MAP), peripheral oxygen saturation, Ramsey Sedation Scale (RSS), pain Numerical Rating Scale (NRS), propofol requirement, adverse events, endoscopists and patients satisfaction were recorded

The level of sedation was assessed at 1-3 min intervals, and the infusion rate was adjusted accordingly to achieve a Ramsay Sedation Scale (RSS) score of 5. Any movement of the patient was treated by increasing infusion rate and the infusion was discontinued at the end of the procedure. The total propofol consumed was calculated and the recovery time was recorded and calculated as the time from discontinuation of infusion of the study drug till achievement of RSS score of 3. Then patients were discharged to post-anesthesia care unit (PACU) after attaining an Aldrete Recovery Scale Score of 9- 10 \[19\]. Time taken to achieve this score was also recorded.
Sedation was initially started by bolus dose of 0.5 mg/kg propofol IV over 3 minutes then, infusion was started at the rate of 50 µg /kg/min till RSS score of 5.

The time to reach Ramsay Sedation Scale score of 5 to ensure adequate sedation. This scale is between 1-6. The score 5 and 6 indicates adequate sedation while score \<5 indicates inadequate sedation.
