Evaluation of efficacy and safety of perioperative multiple intravenous tranexamic acid administration in complex acetabular fractures
Objective To explore the efficacy and safety of perioperative multiple intravenous tranexamic acid(TXA)administration in complex acetabular fracture.Methods The patients with complex acetabular fractures admitted to the Department of Orthopedic Surgery/Trauma Center of West China Hospital,Sichuan University between September 2021 and December 2022 for a planned surgery were selected.The patients were randomly divided into a control group and an experimental group according to TXA administration protocol.The general information,total blood loss,48 h postoperative blood drainage,recessive blood loss,fibrinolysis index,transfusion rate,and incidence of venous thrombotic events of the included patients were observed.Results A total of 60 patients were included,including 41 males and 19 females;30 cases in each group.There was no statistically significant difference in gender,age,body mass index,surgical approach,and surgical duration between the two groups of patients(P＞0.05).There were statistically significant differences in total blood loss[(795.90±451.36)vs.(579.70±315.88)mL],48 h postoperative blood drainage[(231.33±130.77)vs.(147.67±73.14)mL],recessive blood loss[(406.23±356.17)vs.(170.30±163.75)mL],and transfusion rate(63.3％vs.36.7％)between the control group and the experimental group(P＜0.05).There was no statistically significant difference in the preoperative incidence of intramuscular vein thrombosis and the postoperative incidence of deep vein thrombosis and intramuscular vein thrombosis between the two groups of patients(P＞0.05).All patients did not experience pulmonary embolism after surgery.The hemoglobin and hematocrit of both groups showed a decreasing trend.But there was no statistically significant difference in hemoglobin and hematocrit between the two groups(P＞0.05).Both groups showed different trends in fibrinogen and D-dimer,and the experimental group was better than the control group(P＜0.05).Conclusion Multiple intravenous administration of TXA in complex acetabular fractures patients has proven to decrease the total and hidden blood loss,decrease perioperative blood products transfusion rate,and do not expose to venous thrombotic diseases risks.
