Comparison of Propofol-Fentanyl and Propofol-Ketamine for Sedoanalgesia in Percutaneous Endoscopic Gastrostomy Procedures

Background: Percutaneous endoscopic gastrostomy (PEG) procedures are performed under sedation in critically ill patients who cannot be fed orally. Aim: We compared the efficacy and safety of propofol-fentanyl and propofol-ketamine for deep sedation in patients undergoing PEG. Retrospective Study. Materials and Methods: The study was conducted from 1 January 2013 to 31 December 2018 in Adiyaman University. The patients given propofol-fentanyl (0.5-1.2 mg/kg and 0.2-1 mu g/kg, respectively) for sedo-analgesia were designated Group F, and those who received propofol-ketamine (0.2-0.6 mg/kg and 0.5-1 mg/kg, respectively) were placed in Group K. The demographic and hemodynamic characteristics, recovery times, perioperative complications, and need for additional doses were recorded. Results: Seventy-one patients who underwent PEG were analyzed. The age, sex, American Society of Anesthesiologists (ASA) score, comorbidities, duration of anesthesia, and duration of the PEG procedure were similar in the two groups. Recovery time was longer in Group K. The total propofol dose was 64 mg in Group F and 35 mg in Group K. Additional doses of propofol were administered to 12 patients in Group F, compared to none in Group K. The mean blood pressure values were higher in Group K at all-time points. The perioperative complication rate was higher in Group F. Desaturation was observed in 9 (22.5%) patients in Group F and in 3 (9.6%) patients in Group K. Hypotension was observed in 4 (10%) patients in Group F. Conclusion: Propofol-ketamine should be preferred for sedoanalgesia during PEG procedures because of the lower dose of propofol, more stable blood pressure, and greater peripheral oxygen saturation. In addition, we believe ketamine-propofol is safer based on its low complication rate.
