  • Plasma aldosterone levels at 12 hours and 24 hours [ Time Frame: 12 hours and 24 hours postoperatively ]
  • Total time on ventilator, ICU length of stay, total length of stay in hospital [ Time Frame: total length of hospital stay ]
  • pre and postoperative diuretic dose used [ Time Frame: pre operative and postoperate ]
  • Need or absence of need for inotropic support in the 72 hour perioperative period [ Time Frame: 72 hours perioperative ]

Enrollment: 40
Study Start Date: March 2003
Study Completion Date: October 2007
Primary Completion Date: October 2007 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Neseritide
    Dose of Nesiritide infusion will be 0.005 ug/Kg/min
    Other Name: BNP, Nesiritide
Detailed Description:
This is a randomized, double-blind, placebo controlled study of low dose nesiritide to prevent renal insufficiency after cardiopulmonary bypass surgery. Patients included are those with greater than mild renal insufficiency preoperatively as defined by having a creatinine clearance of less than 50 mL/minute determined by the Cockroft-Gault formula. The infusion of nesiritide (BNP) 0.005 mcg/Kg/minute or placebo begins 1 hour before surgery and runs for 24 hours started after the induction of anesthesia prior to cardiopulmonary bypass.
