Prophylactic Tranexamic Acid Reduces Postpartum Hemorrhage

Postpartum hemorrhage (PPH) is the most significant leading cause of pregnancy-related mortality in high-risk cesarean delivery women. Systemic autoimmune diseases are associated with adverse pregnancy outcomes (APOs), including PPH, preeclampsia, thromboembolism, abortion, and intrauterine growth restriction. The incidence of PPH in women with systemic lupus erythematosus has been reported to be as high as 34%. Prevention of PPH is the key to reduce complications in high-risk women. In recent years, a large number of clinical studies have confirmed that the early preventive use of tranexamic acid(TXA) can reduce the amount of blood loss, the need for additional uterine contraction agents, the risk of blood transfusion, and maternal adverse outcomes, and do not increase the risk of thromboembolic events, which can be used to prevent PPH. However, the study population of TXA is mainly low
