Outcome of triplet pregnancies resulting from IVF at Bourn Hallam 1984-1987.
43 consecutive sets of triplet pregnancies progressing beyond 16 weeks and conceived following in vitro fertilisation at the Bourn Hallam Centre between 1984-1987 were included in the study. Follow-up information was available in the 31 sets born to United Kingdom residents. 91 live births resulted at an average gestation of 33 weeks and 2 days (range 26-38 weeks). All but one of the deliveries was by Caesarean section. The average birth weight was 1.85 kg and was significantly higher in the first-born triplet than in the third (1.93 kg versus 1.74 kg, respectively). The perinatal mortality rate amongst the triplets was 32.26 per thousand births, and the neonatal death rate was 21.98 per thousand live births. This compares favourably with the latest published data on perinatal mortality rates in triplets.
