Insights

Fenoldopam infusion in children with congenital heart disease was associated with a decrease in fluid balance and fluid input. Higher blood urea nitrogen levels may predict a positive response to fenoldopam treatment.

Area of Science:

  • Pediatric Cardiology
  • Critical Care Medicine
  • Pharmacology

Background:

  • Children with congenital heart disease (CHD) often experience fluid balance challenges in the cardiac intensive care unit (CICU).
  • Optimizing fluid management is crucial for improving outcomes in critically ill pediatric cardiac patients.

Purpose of the Study:

  • To investigate the effect of fenoldopam on fluid balance in pediatric patients with CHD.
  • To identify factors associated with a decrease in fluid balance during fenoldopam infusion.

Main Methods:

  • Retrospective review of 46 pediatric patients in the CICU receiving fenoldopam infusion between January 2014 and December 2018.
  • Analysis of demographic, clinical, laboratory, hemodynamic, and fluid balance data before and after fenoldopam initiation.
  • Comparison of patient characteristics between those with and without a decrease in fluid balance.

Main Results:

  • Fenoldopam infusion was associated with a statistically significant decrease in systolic and diastolic blood pressure.
  • A majority of patients (74%) experienced a decrease in fluid balance, and 54% had decreased fluid input.
  • Fenoldopam was not significantly associated with an increase in urine output, though 39% showed an increase.
  • Higher baseline blood urea nitrogen levels were observed in patients with a decrease in fluid balance.

Conclusions:

  • Fenoldopam administration in children with CHD is linked to reduced fluid balance and fluid input.
  • The drug's effect on fluid balance may be influenced by factors such as baseline blood urea nitrogen levels.
  • Further research is warranted to identify specific patient subgroups who may benefit most from fenoldopam for fluid management.

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Heart Failure Drugs: β-Blockers

β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...
