[The value of special care in risk pregnancies in order to prevent low birth weight. 1. Results of treatment].

In this paper the results of special monitoring of pregnancies with risks are reported and compared with a collective of not specially monitored pregnancies with risks. It is possible to reduce the total rate of low birth weights and the rate of premature infants significantly by special care with consequent use of a schedule of monitoring. The rate of premature infants was 3.7 per cent in the specially monitored collective as far as the women were accessible to a prolongation of gestation. In the cases of birth weights up to 2500 g a significant removal towards higher and more favourable birth weights can be achieved by special monitoring. The causalities in the premature infants are demonstrated. The prolongation of gestation by cerclage is to be considered as a partial success.
