Emergency childbirth rupture. Bleeding after delivery (postpartum hemorrhage) After delivery of the baby, a uterus that is not contracting (atonic uterus), ruptured uterus, remaining parts of placenta or baby or infected remaining parts of placenta or baby can cause severe bleeding. Postpartum bleeding is usually managed preventatively by massaging the lower abdomen (fundal massage), which increases contraction of the uterus and stops bleeding. Additionally, steady traction is applied to the cord to prevent trauma, cord avulsion (tearing of the umbilical cord), uterine inversion, and retained placental products, all of which can increase blood loss and/or the risk of infection. Postpartum hemorrhage is
Percutaneous umbilical cord blood sampling Percutaneous umbilical cord blood sampling "For other uses see PUBS ( page)" Percutaneous umbilical cord blood sampling (PUBS), also called cordocentesis, fetal blood sampling, or umbilical vein sampling is a diagnostic genetic test that examines blood from the fetal umbilical cord to detect fetal abnormalities. Fetal and maternal blood supply are typically connected in utero with one vein and two arteries to the fetus. The umbilical vein is responsible for delivering oxygen rich blood to the fetus from the mother; the umbilical arteries are responsible for removing oxygen poor blood from the fetus. This allows for the fetus’ tissues to
