球英文句子英翻中

PTB can occur spontaneously or as a result of medical intervention for fetal or maternal indications.

A large retrospective cohort study examining the outcome of twin pregnancies in

the United States between 1989 and 2000 found that 56% of the PTBs seen in twin gestations were medically indicated and 44% were spontaneous.

The investigators hypothesized that the observed decline in perinatal mortality among preterm twins between 1989 and 2000 may be related to the increasing proportion of medically indicated PTBs, suggesting that intervention, in some cases, averted fetal or neonatal demise.

Common causes of medically indicated preterm deliveries among twins are maternal hypertension, fetal distress, fetal growth restriction, and placental abruption.
