This prospective study evaluates whether combined intravenous and topical administration of tranexamic acid (TXA) can safely reduce blood loss in patients undergoing primary total hip replacement surgery. Tranexamic acid is commonly used during orthopedic surgery to decrease bleeding and reduce the need for blood transfusions.
Participants undergoing elective primary total hip arthroplasty are assigned to receive either intravenous TXA alone or a combination of intravenous and topical TXA applied directly around the hip joint during surgery. The study compares postoperative blood loss, changes in hemoglobin levels, transfusion requirements, length of hospital stay, and postoperative complications between the treatment groups.
The study also uses rotational thromboelastometry (ROTEM), a specialized blood coagulation monitoring method, to evaluate whether combined TXA administration affects blood clotting or increases the risk of thromboembolic complications such as deep vein thrombosis or pulmonary embolism.
