[Psychomotor development of children born operatively by Caesarian section, vacuum or forceps in the period between 3 and 7 years (author's transl)].

In the period between 1966 and 1977 9,591 children were born at the UFK, Mannheim, and of these 1.008 were operative deliveries (10.5%). Out of these children, 99 of those delivered by section, 39 by forceps, 140 by vacuum and 67 spontaneous births were examined in an alphabetically determined group (R) for mental and motor development. The means used for the follow-up investigation were the Kramer-Binet Intelligence Test, and careful questioning of the parents on their children's early development. No connection between the type of delivery and intelligence quotient could be determined. A mean IQ of 114.4 was found for those delivered by section, 116.6 for those by forceps, and 117.7 for thos delivered by vacuum. The spontaneously-born children had an IQ of 108.7. The IQ results determined were correlated with the following data: EPH-gestosis, alteration in the child's heart sounds, protracted birth and Apga. No significant differences in the intelligence or any delayed motor development could be found in relation to the comparative group.
