Summary

Acute renal failure (ARF) in newborns stems from various endogenous and exogenous factors impacting kidney function. Preventive measures and timely diagnosis are crucial for improving outcomes in neonatal kidney injury.

Area of Science:

  • Neonatology
  • Nephrology
  • Pediatric Critical Care

Context:

  • Neonatal acute renal failure (ARF) is a significant concern.
  • It arises from endogenous factors like hypotension and septicemia, and exogenous factors including mechanical ventilation and nephrotoxic drugs.
  • These factors disrupt intrarenal vasoactive balance, affecting glomerular filtration rate (GFR), especially in premature infants.

Purpose:

  • To review the causes, diagnostic considerations, and management strategies for ARF in newborns.
  • To highlight factors influencing renal prognosis and discuss current and emerging therapeutic interventions.
  • To emphasize the importance of preventive measures in neonatal kidney protection.

Summary:

  • ARF in newborns is caused by factors disrupting renal vasoactive forces, impacting GFR.
  • Accurate diagnosis, prompt treatment, and avoiding iatrogenic complications are key to prognosis.
  • Plasma creatinine requires cautious interpretation in early neonatal life.
  • General kidney protection involves fluid balance, ventilation, and judicious drug selection.
  • Diuretics and dopaminergic agents are used, with novel therapies like theophylline and endothelin antibodies on the horizon.
  • Renal replacement therapies are feasible, but prevention remains the most effective strategy.

Impact:

  • Provides a comprehensive overview of neonatal ARF for clinicians and researchers.
  • Informs therapeutic strategies, emphasizing prevention and early intervention.
  • Contributes to improving the management and outcomes of kidney injury in critically ill newborns.
