Postoperative anemia has been a threat to total hip arthroplasty patients. We introduced a novel medullary cavity hemostasis (MCH) technique and combined it with tranexamic acid (TXA) to prevent postoperative anemia in elder patients. This trial was conducted to evaluate the effectiveness and safety of this technique.
In this retrospective consecutive study, each group has 88 patients who were all over 70 years old. In the control group, patients were given TXA. In the experimental group, the MCH technique and same TXA application were used.
The average of total blood loss, drainage volume, and hidden blood loss were significantly less in the experimental group. The postoperative hemoglobin (Hb) level was significantly higher in the experimental group (100.6 g/dL) than it is in the control group (81.4 g/dL). None of the patient has shown signs of prosthesis subsidence, periprosthetical osteolysis, or stem loosening during follow-ups in the average follow-up time of 3 years.
We discovered that application of TXA alone is not sufficient to prevent postoperative moderate anemia in patients over 70 years old. Combination of TXA and MCH is an effective and safe way to alleviate the severity of postoperative anemia.
