The Risk Factors For Postoperative Allogenic Blood Transfusion In Hip Arthroplasty Surgery

Objective To screen the risk factors of postoperative blood transfusion in elderly patients undergoing unilateral hip joint operationMethods We conducted a retrospective study and enrolled consecutive patients(age≥65)undergoing unilateral hip surgery at Nanjing Drum Tower Hospital from June 2013 to May 2019(n=959).In order to identify the independent risk factors of postoperative blood transfusion,we collected patients’ basic information,co-existing diseases,types of operation,intraoperative medication,intraoperative monitoring,postoperative blood transfusion and other information to perform single factor analysis and multiple logistic regression analysisResults A total of 109 patients received blood transfusion,accounting 11.4%Preoperative anemia(P<0.001),heart disease(P=0.033),hip revision operation(P=0.011),amount of intraoperative blood loss≥6.67ml/kg(P=0.001)and amount of intraoperative infusion≥28.81ml/kg(P<0.001)were the independent risk factors of postoperative blood transfusion in elderly patients undergoing unilateral hip joint operation,while preoperative fibrinogen≥2.6g/L(P=0.003),the use of tranexamic acid during operation(P<0.001),intraoperative and temperature monitoring(P=0.008)were the protective factorsConclusions Actively correcting preoperative anemia and hypofibrinogen,using tranexamic acid during operation,and paying extensive attention towards intraoperative temperature protection may effectively reduce the incidence of postoperative allogenic transfusion after unilateral hip surgery in elderly patients.Thus may be helpful to avoid or reduce the occurrence of allogenic transfusion-related complications,and shorten the length of stay.
