The OBJECTIVE was to determine the effect of anemia on the volume of blood loss during total hip arthroplasty in patients with end-stage renal disease. MATERIAL AND METHODS. The study was based on the data of 41 patients with pathology of hip joint who underwent primary hip replacement. In the group 1 – the group of comparison (n=20), there was no correction of anemia. In the group 2 – the main group (n=21), erythropoietin was applied 2 months before the operation, until the blood hemoglobin level exceeded 100 g/l, hematocrit – more than 30 %. RESULTS. In the first group of patients, there was the severe anemia: hemoglobin – (88.6±4.6) g/l, the number of red blood cells – (2.7±0.3·1012)/l, hematocrit – (27±2) %. In the second group, 2 months after using erythropoietin, hemoglobin level was (114.9±7.1) g/l, red blood cell count was (3.6±0.4·1012)/l, hematocrit was (33±2) %. Blood coagulation time before operation was (15.1±2.4) min in the first group, (8.7±1.8) min in the second group. Statistically significant difference was noted in blood loss: 59.2 %. In the first group, red blood cell mass transfusion was required in the volume of (554±205) ml for 18 patients (26 doses), plasma – in the volume of (641±67) ml for 20 patients (40 doses). In the second group, blood transfusion was performed for 3 patients in the volume of (321±116) ml. An inverse correlation between blood hematocrit, blood clotting time and blood loss was noted. The correlation coefficient was 0.9. CONCLUSION. The inverse correlation was indicated between the level of hematocrit, blood clotting time and blood loss. The use of erythropoietin in advance of reaching a blood hematocrit of >30 % could significantly reduce the risk of bleeding, reduce the amount of operating blood loss and reduce complications in the postoperative period. |
