Abstract

The rate of multiple pregnancies with more than 2 fetuses has significantly increased since the introduction of ovulation induction agents. From 1970 through 1978, there were 19 triplets and 6 quadruplets in the authors' department, incidences of 1:1696 and 1:5370, respectively. Eighteen (72%) of the 25 multiple pregnancies followed treatment with ovulation induction agents and 7 were spontaneous. The diagnosis of more than 2 fetuses was made earlier in the induced than in the uninduced pregnancies. Management, initiated upon diagnosis, included bed rest, highprotein diet, ?-mimetic agents, progestins, dexamethasone late in the second trimester, and selective cerclage. The mean gestational age was 34 weeks in the triplets and 35 weeks in the quadruplets. Forty-four percent of the deliveries were by cesarean section and the remainder were by vaginal delivery. The mean weight of the neonates was 1807 g in the triplets and 1950 g in the quadruplets. The mean overall Apgar score was 8.16, and the perinatal mortality was 185 per 1000, corrected (more than 28 weeks) to 137 per 1000. The main neonatal complications resulted from prematurity, and maternal complications noted were postpartum hemorrhage necessitating hysterectomy in 2 patients. The preferable mode of delivery cannot be stated dogmatically. Fetal outcome was similar in vaginal and cesarean deliveries among the various gestational age groups.
