[Application of tranexamic acid in the treatment of intertrochanteric fracture of femur].

Abstract

OBJECTIVE\nTo investigate the application of tranexamic acid in the treatment of intertrochanteric fracture.\n\n\nMETHODS\nFrom January 2017 to October 2019, 100 patients with intertrochanteric fracture were randomly divided into observation group (48 cases) and control group(52 cases). All patients received the same surgical treatment. The control group was given tranexamic acid 20 minutes before operation, and 15 mg/kg diluted in 250 ml sodium chloride injection, intravenous drip;the observation group was given tranexamic acid 0.5 g dissolved in 20 ml normal saline injected into femoral bone marrow cavity for local treatment on the basis of the control group. The blood loss, operation time and postoperative hospital stay were compared between two groups. Hematocrit, hemoglobin, D-dimer and fibrinogen levels were analyzed before and after operation, and the incidence of thrombotic complications was observed.\n\n\nRESULTS\nThe total blood loss, dominant blood loss, hidden blood loss and postoperative drainage volume of the observation group were significantly lower than those of the control group (P<0.05), and the postoperative hospital stay was significantly shorter than that of the control group (P<0.05). The postoperative hemoglobin and hematocrit of two groups were significantly lower than those before operation (P<0.05), while the postoperative hemoglobin and hematocrit of the observation group were significantly higher than those of the control group (P<0.05). The incidence of thrombotic complications in the observation group was 10.42%, which was not significantly different from that in the control group (11.54%)(P>0.05).\n\n\nCONCLUSION\nTranexamic acid combined with systemic and local application has important clinical significance in reducing perioperative blood lossand blood cell loss in patients with intertrochanteric fracture, and has good safety.
