Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To test the efficacy of a low dose of tranéxamic acid (1g) delivered within two minutes of the birth of a child by caesarean section versus placebo for the prevention of postpartum hemorrhage (PPH), defined by a Calculated blood loss of more than 1000mL (calculated blood loss = estimated blood volume x (preoperative Ht - preoperative Ht) / Ht preoperative (with estimated blood volume (in mL) = weight (in kg) x 85) A transfusion into globular concentrates before the second postpartum day (D2);Secondary Objective: - To compare the effect of a low dose of tranéxamic acid (1g) versus placebo, delivered after caesarean delivery on other markers of postpartum blood loss. - To evaluate the impact of a low dose of tranéxamic acid (1g) versus placebo, delivered after caesarean delivery, on the occurrence of potential side effects of traxenamic acid;Primary end point(s): Incidence of PPH defined by a calculated blood loss > 1,000mL [Calculated estimated blood loss = estimated blood volume × (preoperative Ht – postoperative Ht)/preoperative Ht (where estimated blood volume (mL) = booking weight (Kg) × 85)] or red blood cell transfusion before day 2 postpartum. Preoperative Ht will be the most recent Ht within one week before delivery. Postoperative Ht will be measured at D2.;Timepoint(s) of evaluation of this end point: On the day of the cesarean delivery | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1) other markers of postpartum blood loss: mean calculated blood loss > 500mL, >1000mL, and >1,500 mL; total mean calculated blood loss; mean gravimetrically estimated blood loss at the end of the cesarean delivery just before the transfer of the women to the PACU, and just before discharge from PACU, by measuring the suction volume and swab weight; proportion of women requiring supplementary uterotonic treatment including sulprostone; incidence of postpartum transfusion; incidence of arterial embolisation and emergency surgery for PPH; mean peripartum change in haemoglobin (difference between the most recent Hb within one week before delivery and at D2); mean peripartum change in hematocrit (difference between the most recent Ht within one week before delivery and at D2); 2) occurrence of potential adverse effects of TXA after cesarean delivery: Hemodynamic parameters (heart rate, blood pressure) 15, 30, 45, 60 and 120 minutes after delivery; nausea, vomiting, phosphenes, dizziness during the stay in the labor ward; mean urea and creatinemia as well as prothrombin time (PT), active prothrombin time (aPTT), aspartate and alanine transaminase, total bilirubin and fibrinogen at D2 ; deep venous thrombosis, pulmonary embolism, myocardial infarction, seizure, renal failure defined by the need for dialysis, occurring within twelve weeks after the delivery; 3) women’s satisfaction assessed by a self-administered questionnaire at day 2 and eight weeks postpartum;Timepoint(s) of evaluation of this end point: On the day of the cesaerian delivery, immediate postpartum, and at day 2, week 8 and week 12 postpartum | — |
