Periviability: A Review of Key Concepts and Management for Perinatal Nursing

Area of Science:

• Obstetrics and Neonatology
• Perinatal Medicine
• High-Risk Pregnancy Care

Background:

• Births at the threshold of viability (20 0/7 to 25 6/7 weeks) pose significant risks of neonatal death and lifelong complications.
• While neonatal survival rates for premature infants have improved due to advanced care, the incidence of preterm birth in this range remains unchanged.
• Managing pregnancies at periviability requires complex counseling due to uncertainties in survival and long-term outcomes.

Purpose of the Study:

• To review current neonatal statistics regarding short- and long-term outcomes for infants born near viability.
• To outline key concepts in the obstetric clinical management of anticipated periviable births.
• To provide guidance on counseling strategies for shared decision-making between clinicians and families.

Main Methods:

• Review of current neonatal statistics and outcomes data.
• Synthesis of established obstetric clinical management principles for periviable births.
• Analysis of counseling approaches for shared decision-making in high-risk perinatal scenarios.

Main Results:

• Survival rates for infants born at earlier gestational ages have increased due to advancements in perinatal and neonatal care.
• Despite improved survival, significant risks of severe lifelong complications and disabilities persist for survivors.
• Effective management hinges on understanding current statistics and providing comprehensive counseling.

Conclusions:

• Periviable births necessitate a multidisciplinary approach, integrating advanced neonatal care with sensitive obstetric management and counseling.
• Shared decision-making, informed by up-to-date outcomes data, is crucial for navigating the complex choices faced by families.
• Continued research and refinement of clinical guidelines are essential to optimize care for this vulnerable population.
