Comparison of Dexmedetomidine Administration Strategy for Propofol‐Based Pediatric Sedation for Magnetic Resonance Imaging: A Retrospective Study
Authors' conclusion
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.
