Objective: While there are few studies on the use of ketamine for sedation during MR imaging of pediatric cases, we aimed to investigate the effects of low-dose ketamine administered intramuscularly for vascular access on hemodynamics, sedation and recovery, and MR quality for the first time.
Materials and Methods: A total of 193 pediatric patients aged 1 month to 15 years who received sedation anesthesia for MR imaging were included in this retrospective study. 99 subjects as the group (Group K) administered ketamine 2.5 mg/kg and below intramuscularly, and the propofol-control group (Group C), where 94 subjects were not administered intramuscular ketamine were divided into two groups. The groups were compared in terms of demographic data, sedation and procedure times, anesthetic drug doses, Ramsay sedation score, hemodynamic parameters, recovery time, Modified Aldrete recovery scores, MR quality and side effects.
Results: The mean values of first dose and additional dose propofol mg/kg in Group K were 0.56 (0.45 / 0.71) - 0 (0 / 0), respectively, while in Group C the values were 1.11 (0.87 / 1.33) - 0.14 (0 / 0.5), respectively. In Group K, the mean SAD, DAP, and median values of MAP during the procedure were found to be higher than the values of Group C (p
