The Pharmacokinetics and Pharmacodynamics of Dexmedetomidine in Neonates Following 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.
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.
Inclusion Criteria:
- Patients must be less than or equal to 1 month old.
- Postconceptual age must be > or equal to 37 weeks on the day of surgery.
- Postoperative from cardiac surgery with tracheal intubation/mechanical ventilation in
the immediate post-op period.
- Planned tracheal extubation within 24 hrs post-op.
- Adequate reanl function (serum creatine < or equal to 1.5mg/dL)
- Adequate liver function (ALT < or equal to 165 U/L)
- Isolated heart surgery
- Informed consent
Exclusion Criteria:
- Patients who have received another investigational drug since birth.
- Patients receiving continuous infusions of muscle relaxants in the post-op setting.
- Pateints who have a positive blood culture without a subsequent negative culture of
other evidence of ongoing serious infection.
- Patients who show signs and symptoms of elevated intracranial pressure.
- Post-op hypotension defined by post conceptual age.
- Pre-existing bradycardia defined by age
- Heart block
- Weight < 2kg
- Patients who, in the opinion of the investigator, are not appropriate candidates for
an investigational drug study
