[Prevention and treatment of complications in twin gestation]
From Sept. 1987 to Oct. 1988, a collaborative program of preventing and treating the common complications of nulliparous twin gestations, namely pregnancy induced hypertension, anemia, premature labour and postpartum hemorrhage was carried out in nine hospitals according to the same plan. There were 91 subjects who met the above criteria (treated group) and 99 cases not included in the plan (control group). The incidence of pregnancy induced hypertension was 33%, anemia 13.2%, postpartum hemorrhage 6.6%, and perinatal mortality 22%, in the treated group. The mean duration of pregnancy was 38.38 weeks (268.7 days) and the mean neonatal birth weight was 2725.8 g. The rate of maternal and fetal complications and prenatal mortality in the treated group were significantly lower than those of the control group.
