Delivery in the 'grey zone': collaborative approach to extremely preterm birth.

During the recent New South Wales and Australian Capital Territory consensus workshop on Perinatal Care at the limits of viability, recommendations were made in the areas of education, counselling and management. Critically, there was a consensus that between 23 weeks and zero days and 25 weeks and six days of gestation, it was reasonable to offer the option of non-initiation of resuscitation and intensive care. Within this, obligation to treat increases as the gestation advances. Implications of the statement for obstetricians are discussed in this article.
