[Prognostic and therapeutic implications of the antenatal care of multiple pregnancies].

From January 1967 to April 1978, 175 twin deliveries occurred among 19,935 deliveries (.88%). A comparison to the literature a low perinatal mortality of 4.57% (adjusted 2.84%) was noted. The reason for the 3 to 5 fold increase in perinatal mortality compared to single on pregnancies was investigated. Review of the records showed conditions specific for twin pregnancies. The treatment necessary to improve the prognosis for twin pregnancies was discussed. It is suggested that the perinatal mortality of 2% for twin pregnancies can be achieved with intensive antenatal care for twin pregnancies.
