[Initial management of primary postpartum hemorrhage]

Accurate management of primary postpartum hemorrhage requires perfect knowledge of a recent protocol accessible at all times. Staff members and equipment need to be adjusted to the emergency situation. The first step is to establish a rapid diagnosis. This could be done with collecting bags, placed immediately after the birth. Once the diagnosis has been established, it has to be communicated to the whole team including obstetricians, midwives and anesthetists. A search for the cause of the hemorrhage is premordial. Abdominal uterine palpation confirms the diagnosis of uterine atony, the most frequent cause of postpartum hemorrhage. Two management schemes are possible depending on whether or not there is retention of the placenta. When the placenta is retained, manual removal has to be performed to empty the uterine cavity and to rule out uterine rupture. After placental delivery, manual control of the uterine cavity is always required. Uterine massage has to be performed after the intrauterine manoeuvres and must not be stopped too quickly. Rapidly other origins can be excluded: episiotomy or low genital tract lacerations requiring rapid repair, coagulation disorders requiring specialised care, or hematomas. During the same time, uterotonic drugs have to be used. Oxytocin (intravenous injection of 5 to 10 IU) is generally employed. Prostaglandins cannot be proposed as publications reporting their efficiency are not validated. Meanwhile, the anesthetists will have begun the first measures of resuscitation.
