Abstract:
OBJECTIVE:To observe therapeutic efficacy and safety of low molecular heparin calcium (fraxiparine) combined with vapour-pressure type blood circulation driver for the prevention and treatment of postoperative lower limb deep vein thrombo-sis(DVT)in elderly fracture patients. METHODS:80 elderly patients receiving fracture surgery were randomly divided into con-trol group and observation group,with 40 cases in each group. Control group only received preventive measures for lower limb DVT under the action of vapour-pressure type blood circulation driver,while observation group was additionally given Low molecu-lar heparin calcium injection on the basis of control group,Preoperative 2 h,postoperative 12 h and 24 h,0.4 ml was administrat-ed;Postoperative d2-d3,0.4 ml was subcutaneously injected;postoperative d4,0.6 ml was administrated and lasted for 10 d. The incidence of lower limb venous thrombosis,therapeutic efficacy,the changes of blood rheology indexes and the cross-section diam-eter difference of uninjured side limb were observed in 2 groups;the incidence of ADR was compared between 2 groups. RE-SULTS:The observation group;total effective rate (95.00%) was higher than control group (72.50%),with statistical signifi-cance (P<0.05). After treatment,the cross-section diameter difference of side and uninjured side limb in observation group de-creased to(1.10±0.87)cm,which was significantly lower than control group(2.59±1.55)cm,with statistical significance(P<0.05). The blood viscosity at both high and low shear rates,plasma viscosity and fibrinogen of observation group were all better than those of control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:In the prevention of lower limb DVT in elderly fracture patients,Low molecular heparin calcium injection combined with vapour-pres-sure type blood circulation driver show high effective rate,significantly improve blood rheological index and lower the incidence of lower limb DVT with good safety.
