Schmitz A, et al. - In children undergoing diagnostic magnetic resonance imaging, researchers pursued a comparative examination of the clinical effects of propofol-mono-sedation vs a combination of propofol and ketamine at induction and a reduced propofol infusion rate for maintenance. Findings exhibited that both sedation concepts were reliable with a low incidence of side effects. Faster postanesthetic recovery was achieved through ketamine at induction with a reduced propofol infusion rate.
