Objective To explore the clinical application of the postanesthetic autologus donation and the post-operative transfusion during the knee and hipreplacement surgeries. Methods Thirty-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.Results Of the 33 patients, 27 only received autologoustransfusion, 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 postanesthetic 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(Plt;0.01). Conclusion Postoperative blood transfusion following the postanesthetic and preoperative autologous donation can be successfully applied to most of the patients undergoing theknee or hip replacement so as to reduce complications of the allogeneic blood transfusion.
OBJECTIVE: To observe the clinical results in the anterior stabile operation of spinal fracture using red blood salvage. METHODS: Nineteen cases with spinal fracture were performed the anterior decompress operation. Blood cell salvage were used during operation. Other 20 cases were also reviewed as control group, who were received the same operation without blood cell salvage. RESULTS: In the 19 cases, average volume of autologous transfusion was 536 ml. Only two cases had homologous transfusion requirements. In the control group, all cases needed homologous transfusion (averaged 947 ml). CONCLUSION: In the anterior decompress operation, the intraoperative blood salvage is highly effective in reducing transfusion and also improves the security of operation
