RESUMEN
BACKGROUND:In foreign animal experiments and clinical reports, microporous polysaccharide hemospheres are characterized as good hemostatic effect, no delayed bleeding, good biocompatibility, and no adverse reactions in the body. OBJECTIVE:To assess the efficacy and safety of microporous polysaccharide hemospheres on reducing blood loss after unilateral total hip arthroplasty. METHODS:Totaly 98 patients who received unilateral total hip arthroplasty due to femoral neck fractures, 39 males and 59 females, aged 61-77 years, were randomly divided into two groups: test group, treated with 1g microporous polysaccharide hemospheres before suture of wound; control group, treated with electric coagulation hemostasis before suturing. Drainage tubes were placed in the two groups. Hemoglobin, blood loss, alogeneic transfusion rate, drainage volume, coagulation index and incidence of deep venous thrombosis of the lower limbs were compared. RESULTS AND CONCLUSION:The total blood loss, drainage volume, and transfusion rate in the test group were significantly lower than those in the control group (P < 0.01), but there were no differences in D-dimer, platelet count, activated partial thromboplastin time and international normalized ratio between the two groups. One case of each group developed deep venous thrombosis of the lower limbs, and no significant difference was in the incidence of deep venous thrombosis between the two groups. No infection occurred. These findings indicate that microporous polysaccharide hemospheres that are safe, effective and convenient can reduce the visible and hidden blood loss after unilateral total hip arthroplasty.
