Dexmedetomidine Verses Propofol for Paediatric MRI Brain

Summary

MRI though not painful requires deep sedation for children due to the loud noise created. With deep sedation comes respiratory depression so the interest in Dexmedetomidine. For standardization MRI brain was chosen and also for the fact that patients usually have history of convulsions where drugs like ketamine may not be a good option. Patients were recruited after ethics committee approval. After pre-medication with intranasal midazolam 0.2 mg/kg body weight, Intravenous access was established and then patients were divided in two groups. One group received intravenous propofol 2mg/Kg and infusion of 100mcg/per kg body weight per minute. The other group received intravenous bolus of Dexmedetomidine 1mcg/kg over 10 minutes and then a infusion of Dexmedetomidine 1mcg/kg/hour. Primary out come was to study the recovery time of patients sedated with Dexmedetomidine compared to patients sedated with propofol for paediatric MRI brain. Secondary outcome were analysed in terms of time for induction,procedural disruptions due to awakening and haemodynamic stability . Follow up was done on phone for any adverse events.
