[Results and consequences using Prechtl's concept of optimal conditions. Obstetrical and Postnatal complications (author's transl)].

An extended list of Prechtl's list of optimal obstetric conditions was used to describe the history of 200 newborns, randomly chosen from a defined population born in 1972. Differences between the population from Groningen (Prechtl's) and Tubingen, and different definitions of the items used in the list are discussed. Reduced optimal conditions in the history of the mother effectively reduced the optimal conditions in the newborn aswell. This was particularly so in case of: Preterm deliveries and miscarriages, bleedings in the first trimester, preterm onset of labour, operative deliveries, less than 38 weeks of gestational age, and an Apgar score below 7.
