Pathophysiology
Clinical meaning
Neonates experience unique physiological adaptations as they transition from intrauterine to extrauterine life. Cellular mechanisms involve the maturation of various organ systems, particularly the respiratory and circulatory systems. Prematurity can disrupt normal cellular development, leading to conditions such as Respiratory Distress Syndrome (RDS) due to surfactant deficiency. Cellular hypoxia can occur due to inadequate oxygenation, potentially leading to acidosis and tissue damage. The immature immune system in neonates is characterized by limited antibody production, making them vulnerable to infections. Understanding these cellular processes is crucial for early identification and management of complications such as sepsis, jaundice, and metabolic disorders.
