A comparison of ketamine-midazolam combination and propofol-fentanyl combination on procedure comfort and recovery process in pediatric colonoscopy procedures.

OBJECTIVE

To compare the efficacy and safety of midazolam-ketamine combination versus fentanyl-propofol combination in pediatric diagnostic colonoscopy.

METHODS

This is a retrospective study of 68 children undergoing diagnostic gastroenterology with midazolam-ketamine combination (Group-K) or with fentanyl-propofol combination (Group-P) in the pediatric gastroentology department at a Turkish tertiary hospital between January 2015 and June 2017. An intravenous midazolam was administered one minute before ketamine administration in Group K. Intravenous fentanyl was given to Group P, followed by intravenous propofol.

RESULTS

There were statistically no significant differences between the groups as for age, gender, weight, duration of colonoscopy and complications observed during procedure. Ramsay sedation score was significantly higher in Group K. Recovery time and the rate of complications during the recovery of Group-K (23 patients, 65.7%) was significantly higher than that of Group P (8 patients, 24.2%) (p= 0.001).

CONCLUSIONS

Colonoscopy procedures can be quite comfortable in children when using the midazolam-ketamine combination. However, adverse effects related to ketamine were observed during recovery.
