Predictive value of neonatal neurological examination: a follow-up study at 18 months.

From a cohort of 1507 infants in the Perinatal Project at University Hospital, Groningen, 80 infants who had been neurologically abnormal in the neonatal period and 80 controls were neurologically re-examined at 18 months of age. Of the 80 abnormal infants, one had died at age three months and 13 other remained abnormal at 18 months, of whom five had severe neurological dysfunction. Two of the control infants had mild abnormalities at 18 months. The rate of false negative results was low, but there was a high rate of false positive results, indicating a high frequency of transient neonatal morbidity. This study demonstrates the sensitivity of the neonatal neurological examination in selecting newborn infants who are in special need of attention.

Obstetrical-neonatal neurological relationship. A replication study.

A study concerning the relationship between neonatal neurological abnormality and 3 parameters of pre- and perinatal condition in a birth cohort of 1507 infants was replicated in a second cohort of 1655 infants. The 3 parameters chosen were preterm birth, intrauterine growth retardation and neonatal acidemia. The neurological examination in the second cohort was carried out by other examiners than in the first cohort. The incidence of neurological abnormality was again found to be raised in all 3 categories and again least in the acidemic subgroup. Also the finding could be confirmed that only in about half of the neurologically abnormal infants could the 3 parameters have exerted any effect at all, which implies the necessity of further analysis. This replication study shows that neurological examination in the newborn period is a reliable tool for the evaluation of the condition of infants with respect to their pre- and perinatal history.

Obstetrical condition and neonatal neurological morbidity. An analysis with the help of the optimality concept.

In order to increase understanding of the origin of neonatal neurological morbidity, the relationship between the obstetrical and neonatal neurological conditions was studied in a 3-year cohort containing 3162 singleton infants. The infants were neurologically examined at term age according to the technique described by Prechtl. Obstetrical data were documented extensively. Prechtl's optimality concept was applied in the analysis. A statistically significant relationship was found between the obstetrical and neonatal neurological optimality scores. There was no sex difference in the obstetrical optimality, whereas there was in the neurological optimality, to the advantage of the girls. It could be shown that obstetrical conditions such as acidemia, preterm birth and intrauterine growth retardation have a stronger relationship to neurological morbidity when the accompanying obstetrical optimality is lower. In obstetrical practice the application of the optimality concept to obstetrical and neurological data is a helpful complementary refinement.

Preterm birth, growth retardation and acidemia in relation to neurological abnormality of the newborn.

The Groningen Perinatal Project is a follow-up study relating pre- and perinatal conditions to early and late neurological sequelae. A description is given of the first cohort of 1507 children, examined neurologically during the neonatal period, and of their mothers and their pregnancies. In this preliminary analysis three 'final pathways' are considered, i.e. intrauterine growth retardation, preterm birth and acidemia (pH in umbilical vein below 7.20). Significant relationships were found between the 'final pathways' and the neurological findings. Since, however, these relationships account for only a small part of the variance of the latter, it is concluded that the (cumulative) effect of other antenatal variables must be taken into account as well. Results of analyses to this effect will be reported in forthcoming publications.
