How can an antepartum hemorrhage be prevented?

The most effective strategy to prevent postpartum hemorrhage is active management of the third stage of labor (AMTSL). AMTSL also reduces the risk of a postpartum maternal hemoglobin level lower than 9 g per dL (90 g per L) and the need for manual removal of the placenta.

How does placenta previa cause antepartum hemorrhage?

Even in the absence of antepartum hemorrhage, placenta previa carries a risk for postpartum hemorrhage, primarily caused by uterine atony, as the lower uterine segment does not have the same contractile ability as the fundus after delivery.

What is a Circumvallate?

Circumvallate placenta is a placental morphological abnormality, a subtype of placenta extrachorialis in which the fetal membranes (chorion and amnion) “double back” on the fetal side around the edge of the placenta. After delivery, a circumvallate placenta has a thick ring of membranes on its fetal surface.

Can ectopic cause antepartum hemorrhage?

Cervical pregnancy, a rare and life-threatening form of ectopic pregnancy, is associated with torrential haemorrhage. Hysterectomy may be required to control the bleeding.

What nursing management prevents antepartum bleeding?

Nursing Interventions Save all perineal pads used during bleeding and weigh them to determine the amount of blood loss.
