Tell me about abruption: causes, treatment.?

Placenta abruption: This is a separation of the placenta from the uterus wall. This results in bleeding and potential compromise of the fetus. High blood pressure, eclamsia, and trauma are the most common causes.

Placental bleed: Abruption is a bleed from the placenta; a disruption of either the mother or baby's blood supply. Many causes: trauma, high blood pressure, drugs (cocaine), preterm labor, polyhydramnios. Can be very large or very small, so even US can miss a diagnosis. Symptoms: usually preterm contractions, sometimes vaginal bleed. Fetal monitoring is necessary. Wait, watch; abruption can self-heal sometimes.
