Eksperimentel: A
Tranexamic Acid plus standard of care
|
Tranexamic acid given slowly intravenously (15 mg/kg body weight) 15 minutes before surgery followed by a second dose at three hour interval from first dose and third dose at three hour interval from the second + Standard of care (Standard of care includes the routine surgical and anesthetic techniques being utilized to control blood loss)

Tidsramme |
|---|---|---|
|
Total Blood Loss
Tidsramme: Baseline through Day 7 post-surgery
|
Total blood loss was defined as the sum of intra-operative and post-operative blood loss.
It was measured by weighing the drapes/ dressings or swabs prior to soaking to measure difference in weight and checking drain collectors until drains were removed.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Intraoperativt blodtab
Tidsramme: Dag 1 (slut på operationen)
|
Intraoperativt blodtab blev målt ved at veje gardinerne/forbindingerne eller podepindene før iblødsætning for at måle forskellen i vægt og kontrollere drænopsamlere, indtil drænene var fjernet.
|
Dag 1 (slut på operationen)
|
|
Post-operative Blood Loss
Tidsramme: 1, 4, 8 and 24 hours post-surgery
|
Post-operative blood loss was defined as the sum of the drainage volumes measured over post-operative days 1, 2, and at drain removal.
It was measured by weighing the drapes/ dressings or swabs prior to soaking to measure difference in weight and checking drain collectors until drains were removed.
|
1, 4, 8 and 24 hours post-surgery
|
|
Total Blood Loss Assessed by Gross' Formula
Tidsramme: Day 7 post-surgery
|
Gross's formula for estimating total blood loss: Estimated blood volume*[(Hematocrit initial - Hematocrit final)/ Hematocrit average]; where estimated blood volume equals body weight in kilograms (kg) *70 mL/kg.
|
Day 7 post-surgery
|
|
Number of Participants Receiving Transfusions
Tidsramme: Up to day 7 post-surgery
|
A uniform transfusion protocol was maintained for all participants in the study.
Transfusion to be triggered at 8.0 milligram/deciliter (mg/dl) hemoglobin or haematocrit value of 24 percent.
|
Up to day 7 post-surgery
|
|
Change From Baseline in Hemoglobin Levels at End of Surgery, 1 hr Post-surgery, and Mornings of Day 1, Day 2, Day 4, Day 7 or Early Termination (ET) Post-surgery
Tidsramme: Baseline through end of surgery, 1 hr post-surgery, and mornings of Day 1, Day 2, Day 4, Day 7 or ET post-surgery
|
Baseline through end of surgery, 1 hr post-surgery, and mornings of Day 1, Day 2, Day 4, Day 7 or ET post-surgery
|
|
|
Number of Participants With Deep Vein Thrombosis (DVT) Post Surgery
Tidsramme: Day 5 post-surgery
|
DVT was defined if a segment of the deep vein of the lower limb was not compressible or a previous compressive vein became non compressive or there was no flow in the underlying vessel.
Symptoms of DVT included pain in the lower limb, localized tenderness, swelling and warmth.
