Tranexamic Acid for the Prevention of Blood Loss in High Risk Delivered Women

Tranexamic Acid for the Prevention of Blood Loss After Vaginal Delivery in a High Risk Pregnancy: A Double Blind Randomized Controlled Trial

Postpartum hemorrhage and its complications are very well known causes for maternal mortality .Uterine atony is the most common cause for postpartum hemorrhage

Postpartum hemorrhage and its complications are very well known causes for maternal mortality and morbidity especially in developing countries. World Health Organization Recommendations for Active Management of the Third Stage of Labor (AMTSL), on 2012 included the use of uterotonics for the prevention of postpartum hemorrhage (PPH) during the third stage of labor for all births. Tranexamic acid (TA) is antifibrinolytic agent used to decrease blood loss in surgery and health conditions associated with increased bleeding. A Cochrane Systematic Review from the best available evidence to determine whether TA is effective and safe for preventing PPH in comparison to placebo or no treatment the review concluded that TA (in addition to uterotonic medications) decreases blood loss postpartum and prevents PPH and blood transfusions following vaginal birth and abdominal delivery in women at low risk of PPH based on studies of mixed quality. There was insufficient evidence to draw conclusions about serious side effects and the effects of TA on venous thromboembolic events and mortality beside its use in high-risk women was not investigated on

Two infusion bags will be prepared and labeled as bag A (experimental group) containing 1 g/10mL Tranexamic acid diluted with 20mL of 5% glucose water, and bag B (placebo group) containing 30 mL of 5% glucose water. Providers and patients will be blinded to the contents of the bags until the end of the study. TA or placebo will be administered intravenously immediately after the delivery of the fetus.

All providers and delivered women will be blinded for the content of the bags which will be applied for women randomly

Participant in group A will receive 2 ampules of 5 milliliters (mL) Tranexamic acid applied to 20 mL of 5% glucose water slowly intravenously immediately after the delivery of the fetus

Group B will receive 30 mL of 5% glucose water slowly intravenously immediately after the delivery of the fetus

The amount of vaginal blood loss in the third and fourth stages (the fourth begins with delivery of the placenta and ends 2 hours after delivery)

The volume of blood loss vaginally will be measured by weighing a specially prepared pad applied beneath the delivered women buttocks before the delivery of the fetus. An electronic scale will be used to weigh the pads before and after 2 hours of the delivery. The quantity of blood (ml) will be = (weight of used materials - weight of materials prior to use)
