[Birth of triplets and quadruplets in Sweden]

The management of 86 women who were delivered of triplets and 7 women who were delivered of quadruplets between 1985 and 1989 is reviewed. The incidence of triplets and quadruplets was 16.3 and 1.3 per 100,000 deliveries. All of the quadruplets and 45 per cent of the triplets were a result of medical induction of ovulation (IVF 14 per cent). The average gestational age (weeks) and the mean birth weight (gram) was 33.4 +/- 2.3/1930 +/- 450 for the triplets, and 30.0 +/- 3.8/1365 +/- 385 for the quadruplets. Cesarean section was the mode of delivery in 84 per cent of the triplets and 5 of 7 of the quadruplets. The perinatal mortality was 4.7 per cent among the triplets and 14.3 per cent among the quadruplets.
