Résumé
Objective To compare the effects of autologous blood transfusion and allogenic blood transfusion on the patients undergoing selective operation of intervertebral fusion with cage. Methods Forty patients who underwent selective operation of intervertebral fusion with cage in the De?partment of Orthopedics of our hospital from September 2012 to June 2014 were recruited for the study,including 20 cases that received autologous blood transfusion only(group A)and 20 cases that received allogenic blood transfusion only(group B). Preoperative and postoperative results of blood routine examination,body temperature,postoperative recovery indicators and expense of blood transfusion were compared between the two groups. Results The postoperative erythrocyte and hemoglobin of the patients in group A were significantly higher than those in group B(P<0.05). When the amount of blood used during the operation reaches or exceeds 4 units,the expense of autologous blood transfusion was lower than that of allogenic blood transfusion. Conclusion Autologous blood transfusion contributes to higher levels of postoperative erythrocyte and hemoglo?bin. When a large amount of blood is used during an operation,autotransfusion can help to reduce the expense of blood transfusion.
