Fluid management in critically ill pediatric patients with congenital heart disease

Area of Science:

• Pediatric Critical Care Medicine
• Pediatric Cardiology
• Nephrology

Background:

• Fluid overload (FO) is a significant trigger of multiple organ dysfunction in pediatric intensive care units (ICUs).
• Pediatric patients with congenital heart disease (CHD) face elevated risks of fluid management issues due to pre, intra, and postoperative factors.
• Infants with acute kidney injury and CHD are particularly vulnerable to severe edema, capillary leak syndrome, and FO, often associated with poor outcomes.

Purpose of the Study:

• To review current literature on fluid balance management in critically ill children with CHD.
• To discuss the efficacy, dosages, benefits, and drawbacks of diuretic therapies.
• To explore alternative diuretic and nephroprotective drugs and extracorporeal fluid removal techniques in pediatric cardiac surgery.

Main Methods:

• Comprehensive literature review of recent studies on fluid balance in pediatric critical care.
• Analysis of diuretic therapy, including dosages and clinical applications.
• Examination of emerging nephroprotective agents and extracorporeal fluid removal modalities.

Main Results:

• Children with severe renal dysfunction requiring renal replacement therapy (RRT) exhibit a higher incidence of FO, linked to adverse outcomes.
• Correction of water overload is a priority in pediatric fluid management.
• The review synthesizes data on various therapeutic interventions and monitoring strategies.

Conclusions:

• Effective fluid balance management is critical for improving outcomes in pediatric critically ill patients with CHD.
• Diuretic therapy and advanced fluid removal techniques are essential components of care.
• Further research into novel nephroprotective strategies is warranted for this vulnerable population.
