[Children's development after placental dysfunction (author's transl)].
Katamnestic neurological and electroencephalographic studies were performed on a group of 6 to 11 year old children who had been born in the years of 1960 to 1966 with the signs of placental dysfunction. Of a total of 288 children (2,8% of the deliveries at the department of obstetrics & gynecology of the Cologne university) 177 were  analized katamnestically and 152 uncerwent a clinical examination. For comparison a group of 384 children were studied who had been born in the same years spontaneously from vertex presentation after a maximum duration of labour of 16 hours. At the time of delivery these children were mature and eutrophic. 133 children of this group were studied katamnestically and 114 underwent clinical examination. The katamnestic studies showed that the group with symptoms of placental dysfunction differed in their development from the control group: these children learned later to sit, to walk, to speak, to dress without help, and to control urination. No differences were found in the ability to write and to read or in their results at school. However a larger percentage of the control group was found to attend a higher educational institution. No differences were found in the incidence of disease or behavioral abnormalities. Sleeping problems and lact concentration were more often observed in the group of children with symptoms of placental dysfunction. The general clinical examination showed no differences between the two groups. The applied different tests to examine grow movements were performed less perfect in a higher percentage by the children born with signs of placental dysfunction. Even greater differences were found in testing the voluntery skilled movements. The electroencephalogram of children of both groups showed a normal basic activity, a distinct blocking effect and a significant activation upon  hyperventilation. An abnormal and pathological EEG was however significantly more often found in children born with symptoms of placental dysfunction. The results of the examination of the individual children and the combination of these results in the groups of symptoms showed that children with signs of placental dysfunction demonstrated a significantly higher incidence of symptoms. It was furthermore obvious that these symptoms were not singular but part of a complex disturbance which was manifested in the obstetrical characteristics as well as in the katamnesis and in the clinical examination. Thus, these studies have demonstrated a higher rate of morbidity in children with placental dysfunction in addition to the known high perinatal mortality. This points the necessity of an early prepartual diagnosis in particular in pregnancies with predisposition, in order to reduce not only the perinatal mortality but also to avoid the described complications in children born after placental dysfunction.
