The anticipated delivery of an infant at the limits of viability presents parents and professionals with medical, ethical and emotional issues; especially when a decision on the initiation of care has to be made. Since the first publication in 2002 by the American Academy of Pediatrics several (albeit different) guidelines and recommendations on periviability counseling have been published. However, there is no universally accepted way of performing prenatal counseling and, consequently, studies describe heterogeneous counseling practices worldwide.
