ABSTRACT
Objective To explore the clinical efficacy of hidden blood loss after operation of proximal femoral nail anti-rotation (PFNA) for intertrochanteric fracture of femur of the elderly with Bazhen Decoction; To discuss the effects on short-term complications after operation. Methods Totally 87 patients with intertrochanteric fracture treated with PFNA were included in the study. The non-randomized controlled trial design was used to divide them into treatment group (44 cases) and control group (43 cases). Both groups were routinely given traction of the affected limbs and tibia, controlled hypertension, diabetes, anti-inflammatory analgesia, and low molecular weight heparin routine anticoagulation. The treatment group was treated with Bazhen Decoction, one dosage per day, continuous administration to 1 day before discharge. The bleeding volume, blood transfusion volume, hemoglobin, length of stay and short-term complications were observed in the two groups. Results The perioperative bleeding, volume and hospitalization time of the treatment group were all lower than those of the control group, with statistical significance (P<0.05). No patient needed blood transfusion in the treatment group, while two patients in the control group needed blood transfusion, with nine units. There was statistical significance between total blood transfusion volume in the two groups (P<0.05). There was no statistical significance in Hb level between the two groups 2 h after surgery (P>0.05). There was statistical significance in Hb level 12–24 h after surgery and 5 d after surgery between the two groups (P<0.05). There was no statistical significance in short-term complications between the two groups (P>0.05). Conclusion Bazhen Decoction can improve Hb level and reduce recessive blood loss and total blood loss of elder patients with femoral fractures treated with PFNA, which is also good for postoperative rehabilitation.
