Experimental
Placebo Comparator
Tranexamic acid
Placebo
After the routine prophylactic IV or IM injection of the uterotonic used in the hospital protocol's -either oxytocin or carbetocin - (as recommended by the 2014 guidelines for prevention and management of postpartum hemorrhage from the CNGOF), the intervention will be the IV administration of a 10-ml blinded ampoule of the study drug (either TXA or placebo according to the randomisation sequence) to the patient within 3 minutes after birth, slowly (over 30-60 seconds), once the cord has been clamped
