Insights

Fenoldopam may help children with acute kidney injury (AKI) and mechanical circulatory support. One case showed improved kidney function, avoiding dialysis in pediatric cardiomyopathy patients.

Area of Science:

  • Pediatric Nephrology
  • Cardiology
  • Critical Care Medicine

Background:

  • Severe cardiomyopathy in children often necessitates mechanical circulatory support, such as ventricular assist devices (VADs).
  • Acute kidney injury (AKI) is a significant complication in pediatric patients with VADs, associated with high morbidity and mortality.
  • Limited therapeutic options exist for AKI in this vulnerable population.

Observation:

  • Two pediatric patients with severe cardiomyopathy requiring VADs developed AKI.
  • Fenoldopam, a dopamine-1 receptor agonist, was administered to both patients for management of AKI.
  • This represents the initial reported use of fenoldopam in pediatric patients with AKI on mechanical circulatory support.

Findings:

  • In one of the two cases, fenoldopam therapy was associated with a successful outcome.
  • The successful case demonstrated improved urine output and renal function, obviating the need for renal replacement therapy (RRT).
  • The second patient's outcome regarding fenoldopam efficacy was less clear, highlighting variability in response.

Implications:

  • Fenoldopam may be a potential therapeutic option for AKI in pediatric patients with VADs.
  • Further investigation is warranted to establish the safety and efficacy of fenoldopam in this specific patient group.
  • These findings may inform future clinical practice guidelines for managing AKI in critically ill children with cardiac support.

Acute Kidney Injury I: Introduction

Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Renal Failure: Dose Adjustments

In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
