[Perinatal mortality in twin birds (author's transl)].

A retrospective investigation of 146 twin births (1% of all births in our obstetric hospital in 15 years) was presented. Compared with a normal control group, the average age of the women with twin pregnancies was higher on the whole and the number of primaparate was lower. Half of the women had an EPH gestosis. Forty-one percent of the births were premature. Perinatal mortality was 9.5% (first twin: 6.4%; second twin: 13.6%). The higher rate of complications accompanying twin pregnancies during the pregnancy itself and during the birth make intensive supervision necessary.
