The effect of type of delivery upon neonatal outcome in premature twins.
A retrospective study from January 1, 1976, through July 31, 1981, was performed to evaluate the relationship between type of delivery and perinatal morbidity and mortality in twins of birth weight less than 2,000 gm. Vaginally delivered second twins who weighed 601 to 999 gm had increased risk of neonatal mortality when compared to their siblings. Among twins who weighed 1,000 to 1,499 gm, vaginally delivered second twins had significantly lower Apgar score and increased risks of neonatal morbidity in comparison to their siblings, whereas second twins who were delivered by cesarean section had no difference in Apgar score or neonatal morbidity from those of their siblings. In twins who weighed 1,500 to 1,999 gm, a significant increase in neonatal complications in vaginally delivered second twins was not found, although the majority of neonatal complications did occur in vaginally delivered second twins. Cesarean section is proposed as the optimal route of delivery for all twins expected to have a birth weight less than 1,500 gm.
