Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Maternal Death or Transfusion of Packed Red Blood Cells

    Participants were monitored from delivery until hospital discharge or 7 days after delivery (postpartum), whichever is sooner. This is the number of mothers who died for any reason, or had a blood transfusion of 1 or more units (of packed red blood cells, including whole blood or cell saver).

    by hospital discharge or by 7 days postpartum, whichever is sooner

Secondary Outcomes (13)

  • Number of Participants With Estimated Blood Loss Greater Than 1 Liter During Delivery

    From skin incision to transfer from operating room, average of 1 hour

  • Number of Mothers Who Died or Had Thromboembolic Events (Venous or Arterial), Ischemic Stroke, Myocardial Infarction, New-onset Seizure Activity, or Were Admitted to the Intensive Care Unit for More Than 24 Hours

    within 6 weeks postpartum

  • Number of Participants Who Were Transfused With Other Blood Products

    within 7 days postpartum

  • Number of Participants Who Were Transfused With 4 or More Units of Packed Red Blood Cells

    within 7 days postpartum

  • Number of Participants With a Thromboembolic Event (Venous or Arterial), Ischemic Stroke, or Myocardial Infarction

    within 6 weeks postpartum

  • +8 more secondary outcomes

Study Arms (2)

Tranexamic Acid

EXPERIMENTAL

Tranexamic Acid for intravenous administration

Drug: Tranexamic Acid

Placebo

PLACEBO COMPARATOR

Normal saline for intravenous administration

Drug: Placebo

Interventions

A single dose of Tranexamic Acid (1 gram) in normal saline for a total of 50cc, administered intravenously immediately following umbilical cord clamping (or as soon as possible afterward)

Also known as: TXA
Tranexamic Acid

50 cc normal saline administered intravenously immediately following umbilical cord clamping (or as soon as possible afterward)

Placebo

Eligibility Criteria

Age18 Years+
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Scheduled or unscheduled cesarean delivery
  • Singleton or twin gestation

You may not qualify if:

  • Age less than 18 years
  • Transfusion or planned transfusion of any blood products during the current admission because the primary outcome is already pre-determined and the need for transfusion will be unrelated to perioperative hemorrhage
  • Recent diagnosis or history of venous thromboembolism or arterial thrombosis because TXA is a risk factor for thromboembolism, and its use is contraindicated
  • Known congenital or acquired thrombophilias, including antiphospholipid antibody syndrome, because of the increased risk of thrombosis
  • Seizure disorder (including eclampsia) because TXA is a GABA receptor antagonist, and its use has been associated with postoperative seizures
  • Serum creatinine 1.2 or higher or on dialysis, with renal disease, or a history of renal insufficiency, because TXA is substantially excreted by the kidney, and impaired renal function may increase the risk of toxic reactions.
  • Autoimmune diseases such as lupus, rheumatoid arthritis, Sjogren's disease, and inflammatory bowel disease because of hypercoagulability and the increased risk of thrombosis or thromboembolism
  • Need for therapeutic dose of anticoagulation before delivery, because the risk of thrombosis may be increased with TXA
  • Treatment with clotting factor concentrates, because the risk of thrombosis may be increased with TXA
  • Presence of frank hematuria, because the risk of ureteral obstruction in those with upper urinary tract bleeding may be increased with TXA
  • Patient refusal of blood products because the primary outcome is then pre-determined
  • Receipt of TXA; or planned or expected use of TXA prophylaxis
  • Active cancer, because of risk of thromboembolism
  • Congestive heart failure requiring treatment, because of risk of thrombosis
  • History of retinal disease, because the risk of central retinal artery or vein obstruction may be increased with TXA
  • +8 more criteria
