Brief summary:
This study is being conducted to determine what dexmedetomidine does to the body and in turn, what how the body handles the medication.

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 infants who are immediately post-operative from cardiac surgery and require tracheal intubation with mechanical ventilation in the post-operative period. Three bolus doses and infusion doses will be administered to a total of 36 evaluable patients.
