Objective:
To analyze the course of pregnancy and perinatal outcome in 31 twins, 22 sets of triplets and five quadruplet clinical pregnancies following conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) procedures and in relation to 58 singleton pregnancy following the same procedure.
Methods:
Retrospective analysis of maternal and neonatal medical records of 58 singleton, 31 twin, 22 triplet and five quadruplet pregnancies diagnosed at 7-8 weeks gestation following 561 embryo transfer procedures in 628 oocyte collections at the IVF Center in the Maternity Hospital, Kuwait from July 1994 to December 1996.
Results:
The clinical pregnancy rate in 628 cycles proceeding to oocyte collection was 32.6%, there being 58 singletons (50.6%), 31 twins (33.5%), 22 triplets (10.8%) and five quadruplets (2.5%). Early complicated outcomes included 47 miscarriages (23.7%), four ectopic pregnancies (1.9%) and one hydatidiform mole. The spontaneous fetal reduction rate was 20.6% in twin, 45.5% in triplet and 40% in quadruplet pregnancies. There was a significantly higher maternal and neonatal complication rate in the triplet group compared to singletons and twins, including threatened miscarriage, pre-eclampsia, antepartum hemorrhage, longer hospital stay and preterm labor. The chance of operative delivery was higher in high-order multiple pregnancy (HOMP). The major neonatal complications were related to prematurity. Neonatal morbidity and mortality were significantly higher in the triplet group. The need for admission to the Special Care Baby Unit (SCBU) and the Neonatal Intensive Care Unit (NICU) was significantly higher in HOMP. However, there were no statistically significant differences in the perinatal mortality in relation to the degree of HOMP.
Conclusion:
Maternal complications, perinatal and neonatal morbidity after 2 years activities in the IVF Center have been reviewed leading to changes in policies of management, notably a reduction in the number of embryos transferred.
