37. Conventional hemofiltration during cardiopulmonary bypass increases the serum lactate level in adult cardiac surgery

To evaluate the effect of hemofiltration on lactate level in adult patients undergoing cardiac surgery. Hemofiltration increases the lactate level. The study included 283 patients classified into two groups: Hemofiltration group (n=138), hemofiltration was done during CPB. Control group (n=145), patients without hemofiltration. The lactate elevated in group H than group C (P<0.05), and the PH showed metabolic acidosis in group H (P<0.05). The mixed venous oxygen saturation decreased in group H than group C (P<0.05). The number of transfused packed red blood cells was lower in group H than group C (P<0.05). The hematocrit was higher in group H than group C (P<0.05). The urine output was lower in group H than group C (P
