Delayed birth intervals of immature fraternal triplets in preterm labor. A case report.

The preterm birth of immature triplets before 28 weeks is associated with excess morbidity and mortality risks attributable to extreme immaturity. We report a case of fraternal triplets in preterm labor in which the second and third triplet births were delayed 11 days after the first birth, at 26 4/7 weeks' gestation. The later-born sibs were heavier at birth and throughout their neonatal course in the hospital and suffered less severe complications as compared to the first-born triplet. Delayed birth intervals of triplets in preterm labor should be considered to improve perinatal salvage of immature triplets, although a successful outcome is rare and unexpected.
