Triplet, quadruplet and quintuplet pregnancies. Management and outcome.

The management and outcome of 46 pregnancies, 37 triplets, 7 quadruplets and 2 quintuplets, were analysed. Management of pregnancies, initiated upon diagnosis of multiple pregnancy, included bed rest, beta-mimetic agents, dexamethasone late in the second trimester and selective cerclage. The mean gestational age at labor was 235 days in triplet pregnancies, 241 for quadruplets and 220 days for quintuplets. Fifty-four percent of the deliveries were by cesarean section and the remainder per vaginam. The mean weight of the neonates was 1809 g for the triplets, 1837 g for quadruplets and 1284 g for the quintuplets. The mean overall Apgar score was 8.13, total perinatal mortality 14.8% and 9.4% in cases more than 28 weeks. There was no statistically significant difference in the outcome for triplets born vaginally or by cesarean section. In recent years there has been a pronounced reduction in neonatal mortality, dropping from 17.3% during 1970-78 to 5.9% from 1979 to 1983 (p less than 0.05), probably due to the improved neonatal treatment.
