[Delivery of premature infants].

Prematurity is a frequent event and clearly raises an issue concerning how these fetuses with multiple weaknesses should be delivered. Although, a systematic abdominal approach has no scientific basis, there are cases where the caesarean is chosen because of other factors associated to prematurity such as any maternal or fetal indication to terminate the pregnancy while labour induction remains impossible. However, in case of breech presentation, which is often delivered by caesarean, the literature does recommend neither the vaginal nor the abdominal approach. Caesarean in case of prematurity is more difficult because of the absence of any inferior segment and implies making a large incision so as to easily extract these weak fetuses. Increased maternal morbidity related to preterm caesarean sections has been reported through out literature. The viability gestational age limit represents a confounding factor in most studies since caesarean is rarely chosen for these fetuses because of a very low expected survival rate, while it is probably in this situation that the abdominal approach could provide a real benefit. Larger studies are required to show potential advantages. Systematic use of episiotomies or instrumental deliveries in case of vaginal births is not recommended in case of prematurity. Protecting the fetal head with spatulas still requires further evaluations.
