Study Details

Study Description

Brief Summary

The purpose of this investigation is to determine the most effective regimen of administration of tranexamic acid to improve clinical outcome among patients undergoing total knee arthroplasty.

Condition or Disease Intervention/Treatment Phase
  • Drug: Tranexamic acid (TXA)
  • Drug: Placebo Normal Saline (NS)
Phase 4

Detailed Description

Tranexamic acid (TXA) is synthetic lysine analog, which acts as anti-fibrinolytic agent by preventing conversion of plasminogen in to plasmin. Various regimens of TXA administration (routes, doses, timing) have been used to decrease perioperative blood loss and improve clinical outcomes among patients undergoing different orthopedic surgeries. We are conducting this prospective randomized placebo controlled trial to compare the effect of the two most common regimens of TXA administration on hemostasis and clinical outcomes among patients undergoing total knee arthroplasty. All recruited patients receive the first dose of 15mg/kg of IV TXA prior to skin incision. The second dose of 15mg/kg IV TXA or identical placebo is administered prior to the release of the tourniquet.

The assessment of hemostasis is performed using whole blood sample via viscoelastic testing by rotational thromboelastography (ROTEM). A blood sample is collected in the preoperative area and after the administration of each dose of TXA. Clinical data is collected until 90 days after surgery.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Tranexamic acid (TXA)

All patients will receive 15 mg/kg Tranexamic acid (TXA) IV prior to skin incision. This arm will receive a second intravenous dose of 15 mg/kg of Tranexamic acid (TXA) before the release of the tourniquet. The medication is delivered from the pharmacy in a masked syringe labeled as "study medication."

Drug: Tranexamic acid (TXA)
Randomly assigned [1:1 ratio] using a computer generated table of random numbers to 1 of the 2 intervention groups
Other Names:
  • Lysteda
  • Cyklokapron
  • Placebo Comparator: Placebo Normal Saline (NS)

    All patients will receive 15 mg/kg Tranexamic acid (TXA) IV prior to skin incision. This arm will receive a second intravenous dose of placebo (Normal Saline) in the volume calculated to be equal to the volume of 15 mg/kg of TXA. The medication is delivered from the pharmacy in a masked syringe labeled as "study medication."

    Drug: Placebo Normal Saline (NS)
    Randomly assigned [1:1 ratio] using a computer generated table of random numbers to 1 of the 2 intervention groups
    Other Names:
  • Sodium chloride
  • Outcome Measures

    Primary Outcome Measures

    1. Assessment of changes in hemostasis via viscoelastic testing. [intraoperative (min)]

      To compare the magnitude of lysis via lysis indexes.

    Secondary Outcome Measures

    1. Hematocrit [postoperative day 1]

      The comparison of hematocrit recordings from preoperative period to the postoperative period

    2. Length of Hospitalization [up to 7 days]

      Length of hospital stay from day of surgery to discharge from hospital.

    3. The number of blood transfusions [90 days]

      The number of blood products transfused after surgery

    4. Hospital readmissions [90 days]

      The occurrence of hospital readmissions following surgery
