| Perioperative blood loss. Timepoint: Post operative. Method of measurement: After surgery, we add 1000 units of heparin to the collection bucket to prevent coagulation of the washing solution. Then 5cc of washing liquid is added to the vial of EDTA (ethylenediamine triacetic acid) to estimate hemoglobin. Hemocue method is used to estimate intraoperative bleeding. In this method, the amount of hemoglobin in the lavage fluid is multiplied by the total volume of the lavage fluid used, and the result is divided by the volume of serum hemoglobin before the operation, and thus the total amount of blood lost will be determined. | — |
