Early postnatal changes in serum creatinine from birth to peak and subsequent decline in preterm neonates

Key Points

• Peak serum creatinine levels occur shortly after birth, followed by a significant decline.
• The analysis observed trends in renal function across preterm neonates over the initial postnatal period.
• Changes in serum creatinine reflect adaptive renal physiology in affected neonates during early life.
• Continued exploration of neonatal physiology may enhance understanding of preterm infant care.
