Blind randomized trial of a single bolus dose of dexmedetomine followed by a continuous infusion (CIVI) for up to 24 hours in infants who immediately post-operative from cardiac surgery and require tracheal intubation with mechanical ventilation in the post-operative period. Three bolus and infusion dose will be administered to a total of 36 patients.

Further study details as provided by Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD):

Primary Outcome Measures:
  • Pharmacodynamics: vital signs, cardiac rhythm, oxygen saturation, laboratory evaluations and adverse events will be monitored to determine the safety of dexmedetomine.
  • Pharmacokinetics: will measure plasma concentrations for dose escalations of dexmedetomine to determine the maximum tolerated dose (MTD).

Secondary Outcome Measures:
  • Pharmacodynamics: The Bispectral Index Scale(BIS) and the University of Michigan sedation scale will be used to measure the level of sedation and dexmedetomine plasma drug concentrations.
  • Pharmacogenetics: will examine the relationship between genotype, drug exposure and drug response in infants postoperative form cardiac surgery.

Estimated Enrollment: 36
Study Start Date: May 2004
Estimated Study Completion Date: November 2006
Detailed Description:

This clinical trial of three dose rates of dexmedetomine will determine the pharmacokinetics of the drug in infants who remain tracheally intubated postoperatively. An exploratory pharmacodynamic study of a non-invasive device measuring sedation will be performed. Although the pharmacokinetics of dexmedetomine have been described for pediatric patients, the drug disposition in infants has not been well described. A range of doses has been studied, yet there are no reports describing the optimal dose for post-operative pediatric patients. This study will provide data that may allow for improved dosing recommendations in this critically ill population of children.
