Understanding Dexmedetomidine in Neonates After Open Heart Surgery
The purpose of this study is to determine what happens to dexmedetomidine in the body after it has been given to a newborn after heart surgery. We want to learn how long the drug stays in the body, how the drug is metabolized by the body, and how well the medicine works at a particular dose or amount.

- 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.
