Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will measure plasma concentrations of bivalirudin in pediatric patients undergoing cardiac catheterization, cardiac surgical procedures utilizing cardiopulmonary bypass (CPB), or extracorporeal support with ECMO, ventricular support devices (VAD) or lung-assist devices (LAD). The aim is to understand the pharmacokinetics of bivalirudin in these settings.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Pediatric Cardiac Catheterization

Bivalirudin

Intervention Type DRUG

CPB: Per hospital protocol, bivalirudin 1 mg/kg IV will be administered to the patient 10 minutes prior to the start of CPB along with an infusion of bivalirudin at 2.5 mg/kg/hr. Additional bolus doses of 0.5 to 1 mg/kg will be administered for ACTs less than the specified target (either 2 times baseline ACT or \> 400 seconds per the discretion of the patient's providers). 50mg of bivalirudin will be administered to the bypass circuit.

Cardiac Catheterization: Bivalirudin will be administered to the patient as 0.75mg/kg IV bolus followed by a 1.75mg/kg/hr infusion for the length of the procedure. Changes in infusion rate or bolus dosing during the procedure and post-procedure will be at the discretion of the patient's care providers.

ECMO/VAD: Dosing will be informed by the hospital's formulary recommendations(http://online.lexi.com/lco/action/doc/retrieve/docid/chibos\_f/6317841), but will ultimately be determined by patient's primary provider.

Pediatric Cardiac Surgery

Bivalirudin

Intervention Type DRUG

CPB: Per hospital protocol, bivalirudin 1 mg/kg IV will be administered to the patient 10 minutes prior to the start of CPB along with an infusion of bivalirudin at 2.5 mg/kg/hr.

Bivalirudin
