Brief Summary

Intraoperative administration of tranexamic acid (TXA,T) reduces significantly blood loss and blood transfusion requirements during spinal posterior fusion in adolescents with scoliosis. TXA acts mainly by inhibit the plasminogen activator. Desmopressin (DDAVP ,D) can inhibit the fibrinolytic activity by inducing the release of von Willebrand factor from the endothelial cells. But at the same time, it releases tissue-type plasminogen activator (t-PA), which may cripple its hemostatic effect. The investigators supposed that if the investigators combine TXA with DDAVP in scoliosis correction surgery, the blood loss and the transfusion need would be reduced significantly.

Outcome Measures

Primary Outcomes (1)

  • blood loss

    The blood loss include the volume of blood in suction bottles, the weight of sponges and seroma volume of drainage 3 days after surgery. All fluids added to the surgical field intraoperatively were carefully quantified and deducted from the measured blood loss.

    during and 3 days after the surgery

Secondary Outcomes (1)

  • blood transfusion

    during and 3 days after the surgery

Other Outcomes (1)

  • postoperative complications

    up to 24 weeks after the surgery

Study Arms (2)

Group TN

PLACEBO COMPARATOR

Tranexamic acid and sodium chloride injection at 10mg/kg, IV (in the vein) for 30min, before incision.Then at 1mg/kg/h, IV pump, until the surgery is over. Normal saline (NS) 100ml IV for 20min, before incision.

Drug: tranexamic acid and sodium chloride injectionDrug: normal saline

Group TD

EXPERIMENTAL

Tranexamic acid and sodium chloride injection at 10mg/kg, IV (in the vein) for 30min,before incision.Then at 1mg/kg/h,IV pump,until the surgery is over. Desmopressin acetate injection at 0.3μg/kg dissolved in 100ml NS, IV for 20min, before incision.
