Effectiveness and safeties of hemocoagulase and tranexamic acid to reduce perioperative blood loss in intertrochanteric fracture PFNA fixation.

Abstract

This study evaluated the efficacy of hemocoagulase and tranexamic acid (TXA) in minimizing perioperative blood loss in perioperative period of proximal femoral nail antirotation (PFNA) repair. 99 patients having intertrochanteric fracture PFNA fixation were randomly assigned to the hemocoagulase, TXA, and control groups (n=33 per group). In the hemocoagulase group, 1 KU of hemocoagulase was injected preoperatively and postoperatively local sprayed, respectively; in the TXA group, 0.5g TXA was injected preoperatively and postoperatively local sprayed, respectively; and in the control group, 100 mL of physiological saline was injected before surgery and was used by postoperative local spraying, respectively. The hemocoagulase and TXA groups exhibited significant differences in preoperative hemoglobin (HB) and hematocrit (HCT) levels on postoperative days 1 and 3, intraoperative bleeding, 24-hour postoperative drainage, total perioperative bleeding, transfusion rate, and postoperative hospitalization duration compared to the control group. Furthermore, the hemocoagulase and TXA groups showed significant differences in postoperative day 3 HB and HCT levels and postoperative hospitalization duration compared to each other. In conclusions, the combined use of systemic preoperative and local postoperative hemocoagulase and TXA spraying is found to significantly decrease perioperative blood loss in intertrochanteric fracture patients undergoing PFNA. Hemocoagulase is observed to have a superior effect compared to TXA.
