Pharmacokinetics of Dexmedetomidine in Children During Cardiopulmonary Bypass (CPB)
2014年11月21日 更新者：Duke University
Dexmedetomidine is increasingly used for sedation in children placed on cardiopulmonary bypass for heart surgery.
It is also often used after surgery and may be particularly helpful for children with heart disease.
In order for this medication to be helpful and to minimize risks associated with taking the medication, it is important to provide correct dosing for this medication.
Based on evidence from studies of other medications used during heart surgery, it is likely that dosing of dexmedetomidine while on cardiopulmonary bypass is different from dosing in other settings.
The purpose of this study is to evaluate how the heart-lung bypass machine affects dexmedetomidine levels in the body.
