|Official Title:||The Pharmacokinetics and Pharmacodynamics of Dexmedetomidine in Neonates Following Open Heart Surgery|
- PK Profile of Dexmedetomidine [ Time Frame: A sparse PK sampling method was utilized. Between 6-12 PK samples were drawn : After start of infusion (0.5, 4-6, 8 hours), immediately prior to end of infusion and following end of infusion (0.25, 0.5, 1, 2-4, 6-8, 10-12 & 18hrs) ] [ Designated as safety issue: No ]This study measured the concentration of dex in the body and used those concentrations to determine how quickly the body metabolizes and eliminates dex(concentration-time or pharmacokinetic profile).The concentration of dex in the body is determined through serial blood sampling while administering dex and following discontinuation.

Neonates will be administered a single bolus dose of dexmedetomidine followed by a continuous infusion for up to 24 hours post cardiac surgery.
Dosage Level 1=0.25mcg/kg loading dose, 0.2 mcg/kg/hr infusion Dosage Level 1A= 0.35mcg/kg loading dose, 0.3 mcg/kg/hr infusion Dosage Level 2= 0.5mcg/kg loading dose, 0.4 mcg/kg/hr infusion
Other Name: Precedex
This is a single center, dose escalation study of a single bolus dose of dexmedetomidine followed by a continuous infusion for up to 24 hours in neonates who are immediately post-op from cardiac surgery, and require tracheal intubation with mechanical ventilation in the post-op period.
Pediatric populations may benefit from the favorable pharmacodynamic effects of this medication.
