Endocrine factors in the neonatal adaptation

Area of Science:

• Neonatal physiology
• Endocrinology
• Perinatal adaptation

Background:

• Transition to extrauterine life involves complex physiological adjustments.
• Endocrine systems play a critical role in neonatal adaptation.
• Understanding these hormonal mechanisms is crucial for perinatal care.

Purpose of the Study:

• To review current knowledge on endocrine system involvement in neonatal adaptation.
• To highlight the roles of specific hormones in cardiovascular, respiratory, and fluid balance.
• To emphasize the importance of endocrine responses in successful perinatal transition.

Main Methods:

• Comprehensive literature review of clinical and experimental studies.
• Synthesis of evidence on hormonal regulation in neonates.
• Analysis of the roles of catecholamines, glucocorticoids, prostaglandins, vasopressin, endorphins, and the renin-angiotensin-aldosterone system.

Main Results:

• Catecholamines, glucocorticoids, prostaglandins, vasopressin, endorphins, and the renin-angiotensin-aldosterone system are vital for cardiovascular and respiratory adaptation.
• Prolactin, vasopressin, and the renin-angiotensin system regulate body fluid redistribution and salt/water metabolism.
• Endocrine reactions to birth and perinatal pathology are key to successful neonatal transition.

Conclusions:

• Endocrine systems are indispensable for successful neonatal adaptation to extrauterine life.
• Hormonal regulation is critical for maintaining cardiovascular stability, respiratory function, and fluid homeostasis.
• Perinatal endocrine responses are essential for navigating the challenges of birth and potential pathological events.
