Postpartum hemorrhage (PPH) is an obstetric emergency, with an estimated incidence ranging from 2.8% to 7.9%. Recent studies indicate an increasing trend in the frequency of PPH.Although it is more commonly seen in developing countries, it remains a significant cause of maternal morbidity and mortality worldwide. Therefore, early diagnosis and prompt, accurate intervention are critically important.
Despite the rising incidence of PPH, maternal mortality rates have declined. This improvement is largely attributed to better identification of risk factors, timely diagnosis, and effective intervention.
To prevent PPH globally, active management of the third stage of labor has been widely implemented. This approach includes the use of pharmacologic agents, uterine massage, and controlled traction for placental delivery.Among pharmacological agents, the most commonly used include oxytocin, ergot alkaloids (e.g., ergometrine), tranexamic acid, prostaglandin E1 (misoprostol), prostaglandin F2α, and oxytocin analogues (e.g., carbetocin).Oxytocin is the most widely used agent for PPH prophylaxis.
The aim of this study is to compare the efficacy of tranexamic acid and misoprostol in the prophylaxis of postpartum hemorrhage.
