According to a new study it is observed that second twins born at term are at a higher risk of death, due to complications during labor and delivery, than first twins. However, planned caesarean section may prevent such deaths. Researchers analyzed the births of more than 3,200 twins born in Scotland between 1995 and 1998. They found significantly increased risks of death during labor and neonatal death among second twins born at term. No deaths were recorded among 420 second twins delivered at term by planned caesarean section.
The absolute risk of death for second twins was one in 320 due to lack of oxygen during birth and one in 420 for lack of oxygen due to mechanical problems. Researchers say these absolute risks are high in comparison with similar data for singleton term births in Scotland over the same period. Researchers say planned caesarean delivery may offer some protection. Previous studies show second twins are vulnerable to complications during labor and delivery.
