Assessment and management of fluid overload in children on dialysis

Area of Science:

• Pediatric Nephrology
• Cardiovascular Physiology
• Dialysis Technology

Background:

• Children with end-stage kidney disease (ESKD) often experience chronic volume overload due to intravascular fluid dysregulation.
• This fluid overload contributes to left ventricular hypertrophy, impaired cardiac function, and is the leading cause of mortality in pediatric dialysis patients.
• Accurate assessment and management of fluid status are critical but challenging aspects of pediatric dialysis prescriptions.

Purpose of the Study:

• To review emerging objective techniques for assessing fluid overload in pediatric dialysis patients.
• To outline evidence-based management strategies for addressing chronic volume overload in this population.
• To highlight the clinical need for improved fluid management to reduce cardiovascular complications.

Main Methods:

• Literature review of emerging objective techniques for fluid overload assessment.
• Analysis of current evidence for management strategies in pediatric dialysis.
• Focus on non-invasive or objective measures to guide fluid management.

Main Results:

• Emerging objective techniques show promise for more accurate fluid overload assessment in children on dialysis.
• Current management strategies aim to balance fluid removal with the risks of excessive ultrafiltration.
• Optimizing fluid management is essential to mitigate cardiac toxicity and intradialytic symptoms.

Conclusions:

• Improved objective assessment tools are needed to optimize intravascular volume in pediatric ESKD patients.
• Careful management of fluid overload is paramount to reduce cardiovascular morbidity and mortality.
• Further research into effective and safe fluid management strategies is warranted.
