Insights
Improved survival rates for extremely premature babies born at 23-24 weeks gestation necessitate proactive perinatal care. This study evaluates the comprehensive care provided to these high-risk infants and their families.
Area of Science:
- Neonatal Medicine
- Perinatal Care
- Maternal-Fetal Medicine
Background:
- Significant advancements in neonatal care have improved survival rates for infants born at 23-24 weeks gestation.
- A proactive approach to resuscitation and comprehensive care is increasingly adopted for these peri-viable gestations.
- Optimizing outcomes for extremely preterm infants requires integrated antenatal, intrapartum, and postnatal care strategies.
Purpose of the Study:
- To assess the quality and components of perinatal care provided to mothers and infants born at 23 and 24 weeks gestation.
- To evaluate the implementation of a proactive care approach in a tertiary maternity hospital setting.
- To identify key elements of care that contribute to improved outcomes for extremely preterm neonates.
Main Methods:
- Observational study design.
- Retrospective review of perinatal care data for mothers and neonates born between 23 and 24 weeks gestation.
- Data collected over a two-year period at a single tertiary maternity hospital in New Zealand.
Main Results:
- Analysis of antenatal counseling, intrapartum interventions, and postnatal management strategies.
- Evaluation of the delivery of care packages aimed at optimizing outcomes for extremely preterm infants.
- Assessment of the care provided within a specific tertiary care setting.
Conclusions:
- The study highlights the importance of a coordinated and proactive approach to perinatal care for extremely preterm infants.
- Findings provide insights into the current practices and potential areas for improvement in managing pregnancies at 23-24 weeks gestation.
- Effective perinatal care for this vulnerable population involves a multidisciplinary approach encompassing the entire continuum of care.
Abstract:
In recent years, significant improvements in survival and survival-free of major morbidity in babies born at 23+0 to 24+6 weeks of gestation have led to a more pro-active approach to resuscitation at these peri-viable gestations. Antenatal counselling and interventions, intrapartum care and postnatal advice should be part of the package of care provided to optimise outcomes for these babies and their families. This observational study assesses the perinatal care provided to mothers and their babies who were born at 23 and 24 weeks of gestations over a two-year period at a tertiary maternity hospital in New Zealand.

Parentral Nutrition: Centeral and Peripheral Parental Nutrition
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...
Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
