Understanding Dexmedetomidine In Infants Post-Operative From Cardiac Surgery

Official Title

The Pharmacokinetics, Pharmacogenetics, and Pharmacodynamics of Dexmedetomidine In Infants Post-Operative From Cardiac Surgery

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 medication, for the purpose of this trial, is
      used as a short-term sedative for infants who are immediately post-operative from cardiac
      surgery and have a breathing tube and are breathing with the assistance of a mechanical
      ventilator or breathing machine.

Detailed Description

      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.
