title: Ultrasound-guided sampling of umbilical cord and placental blood to assess fetal wellbeing.
abstract: Fetal and maternal placental (intervillous) blood samples were obtained by means of an outpatient ultrasound-guided technique from a 33-week pregnancy with symmetrical intrauterine growth retardation. The baby was delivered by emergency caesarean section because blood gas, pH, and lactate measurements showed severe hypoxic acidosis, due to inadequate placental transfer.
