Sedation MRI - Propofol Versus Propofol-Ketamin in Children
November 26, 2014 updated by: Achim Schmitz
Untersuchung Unterschiedlicher Sedationstechniken für Elektive Magnetresonanztomographie (MRT)-Diagnostik Bei Kindern Anhand Klinischer Und MRT-basierter Outcomeparameter (Propofol Versus Propofol-Ketamin)
Children < 10 years of age often need deep sedation or anaesthesia to allow elective diagnostic magnetic resonance imaging; standard routine protocols are
- propofol induction without other sedative (Propofol much as needed) or hypnotic drugs and propofol infusion 10 mg/kg h
- propofol induction with ketamine 1 mg /kg (little repetitive Propofol doses as needed) and propofol infusion 5 mg / kg h
both protocols are compared with regard to clinical outcome and, in cases with cerebral MRI, cerebral perfusion/blood flow.
Hypothesis:
- reduces recovery time compared to propofol mono sedation
- combination of ketamine-propofol increases incidence of Postoperative nausea and vomiting (PONV) compared to propofol mono sedation
- combination of ketamine-propofol increases global cerebral blood flow and changes regional distribution of cerebral perfusion compared to propofol mono sedation
