Key Points

  • To evaluate the effects of dexmedetomidine administration strategies on propofol-based sedation outcomes in pediatric MRI.
  • Conducted a retrospective analysis
  • Compared maintenance infusion versus bolus administration of dexmedetomidine
  • Measured total propofol consumption and hemodynamic interventions
  • Assessed recovery time after sedation
  • Maintenance infusion of dexmedetomidine reduced total propofol consumption
  • Less hemodynamic instability interventions were needed with maintenance
  • No significant difference in recovery time between groups

Abstract

In propofol-based sedation for pediatric MRI, maintenance infusion of dexmedetomidine after a loading dose reduces total propofol consumption and hemodynamic instability requiring intervention without prolonging recovery time, compared with dexmedetomidine bolus without maintenance.
