The new age of periviability

Area of Science:

• Perinatal medicine
• Medical ethics
• Reproductive health law

Background:

• Periviability, defined as 20 to 25 weeks and 6 days gestation, presents unique challenges due to uncertain fetal survival.
• Advances in neonatal care have shifted the threshold of viability, but outcomes remain variable.
• This period often requires urgent decisions regarding abortion due to fetal anomalies or maternal complications.

Purpose of the Study:

• To review the clinical and ethical complexities of managing pregnancies during the periviable stage.
• To explore the impact of recent legal changes and evolving medical practices on periviable care.
• To emphasize the importance of patient-centered decision-making.

Main Methods:

• Literature review of recent studies on periviability outcomes and management.
• Analysis of factors influencing fetal survival and parental decision-making.
• Examination of legal and ethical considerations, including post-Dobbs abortion access and feticidal injection recommendations.

Main Results:

• Periviable outcomes are influenced by gestational age, fetal weight, institutional resources, and neonatal care access.
• Legal changes have complicated abortion access during this critical period.
• Parental decisions are often guided by personal beliefs rather than solely by statistics, highlighting the need for values-based counseling.

Conclusions:

• Clinicians must balance medical, legal, and ethical factors in periviability care.
• A shared decision-making model, emphasizing ethical principles and patient values, is essential.
• Refined, patient-centered guidelines are needed for compassionate and equitable care at the threshold of viability.
