New Swedish guideline on periviable births A new national guideline on management of periviable births has been issued by the Swedish Neonatal and Obstetric Societies. The guideline focuses on management of deliveries at 22 to 25 weeks of gestation and five interventions are pin-pointed: centralization of care, use of antenatal corticosteroids, mode of delivery (use of C-section), neonatologist present in the delivery room and start of neonatal resuscitation. For each gestational week, a statement is made on whether or not the specific intervention is recommended.
