title: Multifetal reduction of triplets and pregnancy outcome.
abstract: Multifetal pregnancy reduction has been suggested as a strategy to improve pregnancy outcome in grand multiple gestations of three or more fetuses. We prospectively investigated multifetal pregnancy reduction in 13 women with triplet pregnancies in the first trimester following ovulation induction, in vitro fertilization, or gamete intrafallopian transfer procedures. Eleven women whose triplet pregnancies followed similar reproductive technologies and who declined or were not offered the procedure were managed expectantly. Mean (+/- standard deviation) infant birth weight was 2227 +/- 478 g in the multifetal reduction group and 2239 +/- 399 g in the group managed expectantly. Gestational age was 35.5 +/- 2.3 weeks in the study group and 35.7 +/- 2.5 weeks in the triplets managed expectantly. Newborn hospital days as well as newborn and maternal complications were not statistically different between the management groups. Maternal interventions included tocolytic medication, home uterine activity monitoring, and extended hospitalization, and were more common in the triplets managed expectantly than in the study group of triplets reduced to twins. Multifetal pregnancy reduction for triplet pregnancies does not necessarily improve pregnancy outcome, though it may be offered on the basis of parental choice.
