Acute fetal distress after fetal blood sampling (case report).

The authors report a case of acute fetal distress after fetal blood sampling, performed for fetal karyotype because of a precocious and symmetrical fetal growth retardation without maternal hypertension or ultrasonographic evidence of fetal malformation. A cesarean section performed because of acute fetal distress showed the newborn to be hypotrophic, with a major acidosis and a refractory hypoxemia. The new born died despite intensive care. Acute fetal anemia was assumed to be the cause of acute fetal distress. The authors emphasize the use of FHR in fetal survey after fetal blood sampling.
