ObjectiveThis study aimed to evaluate the effect of temperature intervention combined with tranexamic acid (TXA) on perioperative blood loss during spinal fusion and accelerated rehabilitation.MethodBetween August 2014 and July 2019, 310 lumbar fusion at our hospital were randomly divided into 4 groups as follows. Group A (placebo): no TXA and no temperature intervention. Group B: TXA (15 mg/kg) before skin incision. Group C: TXA (15 mg/kg) before skin incision and temperature intervention. Group D: temperature intervention without TXA. The primary outcomes were intraoperative blood loss, postoperative blood loss, total blood loss, and core temperature at different stages. We also recorded the hemoglobin level, blood transfusion rate, prothrombin time on postoperative day 1 (POD1), length of hospital stay, and the incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE).ResultsThe 4 groups showed statistically significant differences in intraoperative blood loss, postoperative blood loss, total blood loss, core temperature after anesthesia, average temperature during the operation, hemoglobin on POD1, and length of stay (P < .05). In contrast, prothrombin time on POD1 and the incidence of DVT or PE did not differ between the groups (P > .05). Comparing the transfusion rate in Group C (6/77, 7.79%) and Group A (17/78, 21.79%), the difference was statistically significant.ConclusionTemperature intervention combined with TXA can significantly reduce blood loss and the transfusion rate of spinal fusion in the perioperative period, reduce the length of stay and accelerate rehabilitation after surgery without increasing the incidence of DVT or PE.Copyright © 2023 the Author(s).
