Postpartum hemorrhage is classified into two groups: early postpartum hemorrhage and late postpartum hemorrhage.
What is the most common cause of early postpartum hemorrhage?
Uterine atony is the most common cause of early postpartum hemorrhage, accounting for up to 80% of cases. Uterine atony is when the uterus fails to contract after delivery of the placenta, leading to excessive bleeding from the blood vessels where the placenta was attached.
Normal ranges for blood loss after delivery are less than 500 ml for vaginal delivery and less than 1000 ml for cesarean delivery. Postpartum hemorrhage is defined as blood loss greater than these amounts or when bleeding causes symptoms of hypovolemia (low blood volume) or hemodynamic instability (low blood pressure or high heart rate).
Trauma is not the most common cause of early postpartum hemorrhage. Trauma accounts for about 20% of cases and includes uterine rupture, cervical and vaginal lacerations, and uterine inversion.
Lacerations are not the most common cause of early postpartum hemorrhage. Lacerations are a type of trauma that can cause bleeding from the cervix, vagina, or perineum.
Hematomas are not the most common cause of early postpartum hemorrhage. Hematomas are a type of trauma that can cause bleeding into the tissues of the vulva, vagina, or perineum.
Uterine atony is the most common cause of early postpartum hemorrhage, accounting for up to 80% of cases. Uterine atony is when the uterus fails to contract after delivery of the placenta, leading to excessive bleeding from the blood vessels where the placenta was attached.
Choice B is wrong because trauma is not the most common cause of early postpartum hemorrhage. Trauma accounts for about 20% of cases and includes uterine rupture, cervical and vaginal lacerations, and uterine inversion.
Choice C is wrong because lacerations are not the most common cause of early postpartum hemorrhage. Lacerations are a type of trauma that can cause bleeding from the cervix, vagina, or perineum.
Choice D is wrong because hematomas are not the most common cause of early postpartum hemorrhage. Hematomas are a type of trauma that can cause bleeding into the tissues of the vulva, vagina, or perineum.
Normal ranges for blood loss after delivery are less than 500 ml for vaginal delivery and less than 1000 ml for cesarean delivery. Postpartum hemorrhage is defined as blood loss greater than these amounts or when bleeding causes symptoms of hypovolemia (low blood volume) or hemodynamic instability (low blood pressure or high heart rate).
