Favourable outcome in 33 triplet pregnancies managed between 1985-1990.

In this paper, we describe the outcome of 33 triplet pregnancies referred to us between 1985 and 1990. They were managed as follows: management at home as soon as the diagnosis was made, then hospitalization at 28 weeks' gestation. Progesterone and beta-mimetics were administered daily, a cesarean section was always performed. One late abortion occurred at 21 weeks. The rate of prematurity was 90.6%, mean gestational age at delivery was 34.1 +/- 3 weeks, and 62.5% of deliveries occurred between 34 and 37 weeks. Ninety-four fetuses were delivered alive. Mean birth weight was 1880 +/- 410 g. Fetal growth retardation rate was 61.8%, including 28 infants under the third centile and 31 under the 10th centile. Perinatal death rate was 4.16% including 2 in utero deaths and 2 neonate deaths. All infants are healthy except for one child with severe mental retardation. These results show that triplet pregnancies can be safely managed, and that selective first-trimester reduction in triplet pregnancies does not appear to be necessary.
