ObjectiveTo explore the clinical application of the postanesthetic autologous donation and the postoperative transfusion during the knee and hip replacement surgeries.MethodsThirty-three patients (17 males, 16 females) admitted for the elective joint replacement surgeries from September 2004 to January 2005 were included in this study. Of the 33 patients, 5 were diagnosed with rheumatoid arthritis, 23 with femoral head necrosis, and 5 with knee osteoarthritis. Immediately after anesthesia, 400 ml of the blood was drawn and transfused after the surgery. The blood pressure was monitored during the blood drawing, postoperative blood parameters were recorded, surgical site drainage and signs of infections were observed, and the other clinical data were collected.ResultsOf the 33 patients, 27 only received autologous transfusion, including 21 patients who underwent the unilateral hip replacement and 6 patients who underwent the unilateral knee replacement. All these 6 patients with the unilateral knee replacement received the blood drained from the surgical sites in addition to the blood obtained from the post-anesthetic autologous donation. Another 6 cases with the bilateral hip and knee replacement received the blood drained from the surgical sites, the blood obtained from the post-anesthetic autologous donation and 400 ml of the allogeneic blood transfusion. The blood received postoperatively averaged 650 ml (range, 200-1 150 ml), haemoglobin (Hb) was averaged 88 g/L (68-102 g/L), and Hct was averaged 24.6% (20.5%-31.5%). Hb and Hct were lower after operation than before operation (P < 0.01).ConclusionPostoperative blood transfusion following the postanesthetic and preoperative autologous donation can be successfully applied to most of the patients undergoing the knee or hip replacement so as to reduce complications of the allogeneic blood transfusion.
