Abstract: Objective:To analyze the form of blood transfusion and the difference of donor blood transfusion volume in patients undergoing elective orthopedics surgery,so as to provide valuable reference information for clinical work in the future.Method:We collected the clinical blood transfusion data of a total of 128 patients undergoing orthopedics surgery in our hospital from April 1 2016 to March 31 2018,and analyzed the age,disease and blood type.The form of blood transfusion and the transfusion volume of allogeneic blood components were studied in retrospective statistical analysis.Result:Of 128 cases of patients undergoing orthopedics surgery with intraoperative blood transfusion,15 cases with autologous blood transfusion,of which 12 cases were treated with hemodilated autologous blood transfusion and 3 cases with salvaged autologous blood transfusion;of 15 cases with autologous blood transfusion,4 cases with autologous combined allogeneic blood transfusion.There was no significant difference in the age distribution among the orthopedics patients with different diseases.There was no significant difference in the average volume of allogeneic blood transfusion between the different kinds of diseases and blood types.The age of the allogeneic and the autologous blood transfusion patients was significantly different,and the age of the autologous combined the allogeneic blood transfusion patients and the autologous blood transfusion patients was also significant.There was no significant difference in age between patients with hemodilated and salvaged autologous blood transfusion.Conclusion:Through the analysis of the blood transfusion in the orthopedics surgery patients of our hospital,the blood preparation experience of various diseases was summed up and the blood storage plan could be made in favor of the Blood Transfusion Department.Autologous blood transfusion is an important measure of blood protection in orthopedics operation,which can effectively save the application of allogenic blood transfusion.
