An Evaluation of Clotting Factor Activity Before and After Total Hip Arthroplasty

"Blood samples were taken before surgery, 6 hours, two, four, and six days after the procedure. Venous blood samples were taken from peripheral veins.~All analyzed parameters (fibrinogen, factor II, factor VIII, factor X, D-dimer) were determined using an ACL TOP 500 CTS automated coagulation analyzer.~All patients were operated on by a single surgical team, with cementless hip replacements implanted, and without tranexamic acid administered in the perioperative period. All patients underwent venous thromboembolic complications prophylaxis.~The following data were collected: age, body mass index, gender, perioperative risk assessment scale according to the American Society of Anesthesiologists score, blood transfusions, hemoglobin levels before surgery and two days post-surgery, instances of thromboembolic complications. Because of the observational nature of this study no changes in the treatment of patients were made."
