Neonatal resuscitation: foetal physiology and pathophysiological aspects

Area of Science:

• Neonatal Medicine
• Pediatric Resuscitation
• Fetal Physiology

Background:

• Neonatal resuscitation is crucial, though only 1% of newborns require advanced life support.
• Anaesthesiologists often manage neonatal resuscitation due to unpredictable needs and specialist unavailability.
• Recent guideline updates from major resuscitation bodies aim to simplify and improve neonatal resuscitation protocols.

Purpose of the Study:

• To review fetal physiology and pathophysiology of neonatal adaptation.
• To provide a scientific basis for understanding the updated neonatal resuscitation guidelines.
• To highlight key changes in the latest neonatal resuscitation recommendations.

Main Methods:

• Review of current international guidelines on neonatal resuscitation.
• Analysis of fetal and neonatal physiological responses to resuscitation.
• Focus on the role of respiratory support and oxygenation monitoring.

Main Results:

• Revised guidelines emphasize respiratory support and heart rate as indicators of effective ventilation.
• A significant change is the recommendation to initiate resuscitation with room air, not 100% oxygen, for term infants.
• Continuous pulse oximetry is advised for monitoring heart rate and oxygen saturation.

Conclusions:

• The updated guidelines simplify the resuscitation algorithm, prioritizing ventilation.
• Room air initiation for resuscitation is supported by physiological rationale.
• Effective ventilation and oxygenation monitoring are central to successful neonatal resuscitation.
