Abstract

Aim The aim of this study was to investigate the effect on the occurrence of emergence delirium of propofol and ketofol with intranasal dexmedetomidine and midazolam applied as premedication to paediatric patients during magnetic resonance imaging (MRI). Methods The study included children aged 2-10 years who received sedation for MRI, separated into four groups. Group MP (midazolam-propofol) received intranasal midazolam (0.2 mg/kg) for premedication and intravenous (IV) propofol (1 mg/kg) as the anaesthetic agent. Group MK (midazolam-ketofol) received intranasal midazolam (0.2 mg/kg) for premedication and IV ketofol (1 mg/kg) as the anaesthetic agent. Group DP (dexmedetomidine-propofol) received intranasal dexmedetomidine (1 mcg/kg) for premedication and IV propofol (1 mg/kg) as the anaesthetic agent. Group DK (dexmedetomidine-ketofol) received intranasal dexmedetomidine (1 mcg/kg) for premedication and IV ketofol (1 mg/kg) as the anaesthetic agent. The Paediatric Anaesthesia Emergence Delirium (PAED) scale was used to evaluate delirium. A PAED score >= 10 was accepted as delirium. Results Statistical analysis was made of 140 paediatric patients. Delirium developed in 1.42% of all the patients, and in 5.7% of Group MP. The mean Aldrete and PAED scores were lower and the length of stay in the recovery room was shorter in Group DP than in the other groups. The need for additional anaesthetic was highest in Group DP at 94.3% and lowest in Group DK at 14.3%. The groups administered ketofol were observed to have a lower requirement for additional anaesthetic. Conclusion Delirium was seen at a very low rate only in the Group MP and it is difficult to say the best combination in terms of delirium frequency. However, intranasal dexmedetomidine and IV ketofol seem to be better and safer than the other groups in terms of the need for additional doses and the number of side effects. The addition of ketamine to propofol reduces the need for additional doses with a synergistic effect.
