The Respiratory Management of the Extreme Preterm in the Delivery Room

Area of Science:

• Neonatal physiology
• Respiratory distress syndrome
• Perinatal medicine

Background:

• The transition from fetal to neonatal life presents significant respiratory challenges for extremely low birth weight (ELBW) infants.
• Postnatal stabilization in the delivery room (DR) is critical but complex for these vulnerable neonates.
• Establishing respiration and functional residual capacity often necessitates ventilatory support and oxygen.

Purpose of the Study:

• To critically review current evidence and guidelines on respiratory stabilization of ELBW infants in the DR.
• To address the complexities of optimal oxygenation and ventilation strategies.
• To explore the impact of recent changes like physiologic-based cord clamping on stabilization.

Main Methods:

• Literature review of current evidence.
• Analysis of international guidelines for newborn stabilization.
• Discussion of fetal-to-neonatal transitional respiratory physiology.

Main Results:

• Non-invasive positive pressure ventilation is recommended as a first-line approach for ELBW infant stabilization.
• Optimal initial inspired oxygen fraction, target saturations, and titration remain areas of active investigation.
• Physiologic-based cord clamping adds complexity to established stabilization protocols.

Conclusions:

• Optimizing ventilation and oxygenation strategies is crucial for improving outcomes in ELBW infants.
• Further research is needed to resolve the "conundrum" of precise oxygen management and saturation targets.
• Current guidelines favor non-invasive ventilation, but individualized approaches considering cord management are essential.
