The purpose of the study reported here was to evaluate the haemostatic function in calves with suspected septic shock and to reflect the occurrence of disseminated intravascular coagulation (DIC). Twenty-six calves suspected of having septic shock (experimental group) and 10 clinically healthy calves (control group) were used. On admission, the experimental group of calves had been ill for an average of 2 days. Therapy was applied to the experimental group of calves. The packed cell volume (PCV), haemoglobin (Hb), white blood cell (WBC), red blood cell (RBC) and platelet (PLT) counts were determined. Blood smears for toxic neutrophil and schistocyte intensity were evaluated. For the coagulation profile, plasma activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), fibrinogen and fibrin/fibrinogen degradation products (FDPs) values were determined. Toxic neutrophils in blood smears were observed in 12 calves of the experimental group. APTT was prolonged in the experimental group compared with the control group (p5 μg/ml, PLT ≤ 150 × 103/mm3) and abnormal erythrocyte morphology (schistocytes ≥ 1). The most common abnormal tests in the coagulation profile were APTT and PT (7 cases), FDPs (6 cases), thrombocytopenia (4 cases), and schistocytes in blood smears (8 cases) in these 8 calves. The results of this study indicate that DIC might be a significant risk factor for mortality in calves with suspected septic shock.
