Table 2. Mean ACT Measured during Hemodialysis (Low Concentrations of Heparin Infusion) and Cardiac Surgery (Baseline and after Protamine Infusion) and during Cardiac Surgery (after Heparin and during Cardiopulmonary Bypass)
*t test for paired samples was used to compare ACT values obtained with the two methods. ACT = activated clotting time; CPB = cardiopulmonary bypass.
