Parental authority, patient's best interest and refusal of resuscitation at borderline gestational age.

Potential conflict exists when parents refuse a medical intervention for their child that the physician feels obligated to provide. For the anticipated delivery of a preterm newborn, this conflict might exist if the parents refuse resuscitation. At borderline viability, most neonatologists are likely to respect the parents' wishes. However, there will be some gestational age threshold above which the physician will feel compelled to resuscitate despite parental refusal, and will be ethically justified in doing so. The location of that threshold should be determined by the application of sound ethical reasoning, rather than relying on habit or arbitrary standards. That reasoning should include an honest assessment of the benefits and burdens to the child, short-term and long-term, of attempted resuscitation, made in light of relevant mortality and morbidity data. However, a rational analysis will also require consideration of whether the patient's best interest standard should be strictly applied, or whether the interests of others, such as family members, should also be taken into account.
