Fluid Management

Most anesthesiologist assure adequate perfusion of the graft by inducing mild hypervolemia and hypertension after revascularization. Fluids are administered to obtain a central venous pressure of 10-15 mm Hg. Achieving a systolic blood pressure of 120-140 mm Hg sometimes requires the use of dopamine infusion (3-10 |ig/ kg/min). In addition, most anesthesiologists also administer mannitol (12.5-25 g) and furosemide (10-40 mg) after release of the vascular clamps to promote urine production.
