Ethical Dilemmas in Neonatal Care at the Limit of Viability

Area of Science:

• Neonatal Medicine
• Perinatal Ethics
• Developmental Pediatrics

Background:

• Neonatal care advances have lowered viability limits, increasing survival of extremely premature infants.
• These survivors face significant risks of long-term neurodevelopmental handicaps, raising ethical concerns.
• Periviable birth management necessitates balancing potential benefits against risks and parental autonomy.

Purpose of the Study:

• To analyze survival rates and neurodevelopmental outcomes at different gestations for periviable births.
• To provide ethical guidance for perinatal management decisions based on gestational age.
• To emphasize the importance of parental autonomy and informed consent in treatment choices.

Main Methods:

• Review of current literature on neonatal survival and outcomes at the limits of viability.
• Analysis of ethical principles, including beneficence and autonomy, in periviable birth scenarios.
• Examination of decision-making frameworks for obstetric and neonatal care providers.

Main Results:

• At 22 weeks gestation, survival is low (1-15%) with common profound disabilities; no beneficence-based obligation for aggressive management.
• At 23 weeks, survival is 8-54%, with 7-23% surviving without severe handicap; cesarean delivery may be offered if indicated and resuscitation planned.
• At ≥24 weeks, survival is higher (up to 51%), with 12-38% surviving without profound disability; beneficence supports intervention, respecting parental autonomy.

Conclusions:

• Ethical obligations for intervention in periviable births are gestational age-dependent.
• Parental autonomy and informed consent are paramount in all treatment decisions.
• Individualized care, based on cooperation between obstetric and neonatal teams, is essential for optimal outcomes.
