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
EXPERIMENTALTranexamic Acid for intravenous administration
Placebo
PLACEBO COMPARATORNormal saline for intravenous administration
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)
50 cc normal saline administered intravenously immediately following umbilical cord clamping (or as soon as possible afterward)
Eligibility Criteria
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
