[Maternal transfer and neonatal transfer].

Regionalisation of perinatal health care has not been organised in France. This concept has proposed to reduce mortality and morbidity of newborns of less than 33 weeks or less than 1,500 g at birth by a transfer of the mother before birth to a perinatal center with a neonatal intensive care unit. The available information in France shows that only 14% of those infants will be born in a level 3 centres. In Seine-Saint-Denis district available information shows that the adds ratio for per partum and neonatal death for newborns of 28-36 gestation duration is of 5.27 when a level 1 maternity is compared to a level 3.
