Dexmedetomidine <em>versus</em> Ketofol for Moderate Sedation in Endoscopic Retrograde Cholangiopancreatography.

OBJECTIVE

To compare the efficacy of dexmedetomidine versus ketofol for moderate sedation in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP).

STUDY DESIGN

Randomised controlled trial. Place and Duration of the Study: Department of Anaesthesia, SICU and Pain Management, Sindh Institute of Urology and Transplantation, Karachi, Paksitan, from December 2021 to June 2022.

METHODOLOGY

Sixty-two patients aged 20-60 years of any gender scheduled for elective ERCP were included. Patients were randomly divided into Dexmedetomidine group (2ml ampule of 100ug/ml diluted in 18ml of normal saline) and Ketofol group (2ml ketamine and 10ml of propofol 1% diluted in 8ml of normal saline) for sedation. The mean difference in time to achieve Ramsay Sedation Scale (RSS) score of 4 and Modified Aldrete's Score (MAS) of 9 were noted as outcomes in each group. In addition, complications during the procedure and recovery were also noted.

RESULTS

The mean age was 39.15 ± 9.82 years. There were 33 (53.2%) males and 29 (46.8%) females. The mean time to achieve RSS 4 was significantly lower in patients who were treated with Dexmedetomidine as compared to Ketofol, i.e., 11.84 ± 1.77 minutes vs. 13.10 ± 1.64 minutes respectively (p-value 0.005, 95% CI -2.12 to -0.39). Similarly, the mean time to achieve MAS score 9 was significantly lower in patients who were treated with Dexmedetomidine as compared to Ketofol, i.e., 11.19 ± 1.72 minutes vs. 12.23 ± 1.84 minutes, respectively (p-value 0.026, 95% CI -1.94 to -0.13).

CONCLUSION

Dexmedetomidine proved to be more effective than Ketofol for sedation in ERCP, achieving faster sedation and quicker recovery.
