[Feto-maternal transfusion. A rare cause of acute fetal distress. A case history (author's transl)].

The authors report a case of feto-maternal transfusion which showed as acute fetal distress spotted by fetal cardiac rhythm monitoring. Following this observation the authors point out such occurrences are rare with a possibility of intra-uterine fetal death at 1/1000. They also point out the value of fetal cardiac monitoring and of systematic performance of amnioscopy at the start of labour and of carrying out the Kleihauer test in every case of neonatal anaemia as well as in every case of unexplained perinatal death.
