Ethical dilemmas in decision making at limits of neonatal viability

The survival rate for extremely preterm infants has improved over the last two decades. Although the incidence of such births is about 2%, the impact of preterm birth on these infants, their families, health-care providers, and society is profound. The birth of an extremely low birth weight (ELBW) and early gestational age infant poses complex medical, social, and ethical challenges to the family and health-care professionals. Survivors have an increased risk of chronic medical problems and disability. It is difficult to make decisions while trying to provide optimal medical care to the infant and supporting the family when delivery occurs at the threshold of viability because outcome at that time is highly unpredictable. Such decisions may have lifelong consequences for those involved. An individualized prognostic strategy appears to be the most appropriate approach. While keeping the patient's best interest as the primary objective, the goal is to reach, through a process of effective communication between the parents and physicians, a consensual decision that respects the parents' wishes and promotes physician beneficence.
