How and why are triplets disadvantaged compared to twins?

Area of Science:

• Reproductive Medicine
• Perinatology
• Neonatal Care

Background:

• The rise in triplet pregnancies is linked to assisted reproductive technologies.
• Triplet pregnancies present significant perinatal challenges compared to twin gestations.

Purpose of the Study:

• To evaluate the outcomes of triplet pregnancies in the context of modern neonatal care.
• To reassess the role of multifetal pregnancy reduction in managing triplet gestations.

Main Methods:

• Review of perinatal outcomes in triplet vs. twin pregnancies.
• Analysis of survival rates and complications in preterm and low-birth-weight triplets.
• Comparison of outcomes with and without multifetal pregnancy reduction.

Main Results:

• Triplet pregnancies face higher rates of preterm birth, low birth weight, morbidity, and mortality.
• Advances in neonatal care have improved survival for preterm and low-birth-weight triplets.
• Multifetal pregnancy reduction is associated with better outcomes, similar to twin gestations.

Conclusions:

• While multifetal pregnancy reduction improves outcomes, recent improvements in triplet care warrant reconsideration of its routine recommendation.
• The decision regarding multifetal pregnancy reduction for triplets should balance risks and benefits in light of evolving neonatal care.
