ANEMIA
After surgery, elastic compression stockings and a mechanical compression device were applied to the lower limbs on both sides. For chemoprophylaxis for postoperative thromboembolism, 15 mg per day of edoxaban, an Xa-inhibitor, was orally administered until one week after surgery. At one week, ultrasonographic examination with pulsed Doppler, color Doppler (Toshiba Medical Systems, Japan) was performed for screening of DVT.Postoperative drainage volume was recorded separately on the first day and second day, and the suction drain was removed on the second day. From the day after surgery, patients were given oral 60 mg of loxoprofen three times a day and 75 mg of pregabalin once a day. For patients with severe pain, additional prescription of tramadol hydrochloride acetaminophen was allowed as needed.The postoperative rehabilitation regimens were the same for both groups, and range of motion exercise was initiated at postoperative day 1. Weight bearing of lower limbs on the surgical side was allowed at two weeks. We evaluated hemoglobin (Hb) at postoperative day 1, 3 and 7. Allogeneic blood transfusion was indicated for patients with Hb < 7.0 g/dl or those with Hb < 10.0 g/dl if they had symptoms related to anemia.
