[The diagnostic value of blood rheology studies in cardiac surgical interventions]

The diagnostic value of routine studies of blood rheology in cardiosurgical patients was investigated. Blood rheology, hemostatic system, and acid-base balance were analyzed in 75 cardiosurgical patients during the early postoperative period. In 41 of these the postoperative period was uneventful and 34 patients developed complications. The blood fluidity conditions and estimation of the risk of thrombotic and hemorrhagic complications were assessed using the "Aggregate Status of the Blood" software. The data indicate a high diagnostic and prognostic significance of plasma viscosity, relative blood viscosity, erythrocyte aggregation and deformability indices in evaluation of the status of cardiosurgical patients in early periods after surgery. Application of hemorheological studies as routine methods for examination of patients improved the quality of treatment. Hence, rheological studies of the blood and plasma should become an obligatory component in the diagnosis of the hemostatic status in the early postoperative period after aortocoronary bypass surgery.
