[Low weight and endangering of multiple birth infants].

Multiple pregnancy represents a high risk to the survival of fetuses since insufficient nutrition frequently results in hypotrophic development and low birth weight. The frequency of the occurrence of low birth weight in children from a multiple birth is 10 times higher than in all newborn children and the early noenatal mortality of children froma multiple birth is 8 times higher than that of all newborn infants. The disproportion between the placenta and the fetuses which we usually find in multiple pregnancies may result in the occurrence of cerebral damage. In the period 1965 to 1967 perinatal death associated with cerebral damage by birth injury (recorded on the death certificate) accounted for 5,7% of all children of low birth weight and for 0,2% of children weighing at birth over 2500 g.
