[Twin pregnancy--a special problem of modern obstetric medicine].

Basing on an exemplary organized health protection incorporating up-to-date technique, progressive management of delivery and optimal neonatal care, we were able to reduce the perinatal mortality of all pairs of twins at the UFK Jena in the periods between 1977/79 (n = 204) and 1980/82 (n = 174) from 8,33% to 3,30%. The difference was statistically significant (p less than 0.05). The late morbidity of these children also showed a statistically significant decline (p less than 0.05).
