title: [Morbidity in twins with a weight up to 1500 g and a gestational age up to 32 g. w].
abstract: Seventy-five newborns from multiple pregnancies with very low and extremely low birth weight are studied. 94% of the infants under 1000 g and 66% of those above 1000 g are born by vaginal way. Intrapartal asphyxia develop most often the second twins with birth weight under 1000 g--64.7%. These are the infants with higher morbidity: RDS--56.5%, IVH--100%. The survival rate of the twins of this group is notably lower than that of the infants from singleton pregnancies with equal weight and gestational age: 12.1% under 1000 g and 69% above 1000 g, against 38.3% and 77.9% respectively.
