Body fluid homeostasis in the newborn infant with congestive heart failure: effects of diuretics
1Department of Pediatrics, Centre Hospitalier Universitaire Vaudois, Lausanne, Switzerland.
Insights
Congestive heart failure in neonates involves fluid overload and kidney issues. Diuretics can help but pose risks to cardiac output and cause adverse effects.
Area of Science:
- Neonatal Medicine
- Cardiology
- Nephrology
Background:
- Congestive heart failure (CHF) in neonates presents with extracellular fluid volume expansion.
- Increased venous filling pressure and paradoxical renal sodium retention are key features of neonatal CHF.
- Diuretics are crucial for managing venous pressure but risk cardiac output reduction and adverse effects.
Purpose of the Study:
- To review the pathophysiology of body fluid homeostasis in neonates with congestive heart failure.
- To discuss the adverse effects of diuretic use and abuse in this population.
Main Methods:
- Literature review of pathophysiology.
- Analysis of adverse effects associated with diuretics in neonatal CHF.
Main Results:
- Extracellular fluid volume expansion, elevated venous pressure, and sodium retention characterize neonatal CHF.
- Diuretics, while beneficial for venous pressure, can impair cardiac output and lead to significant adverse events.
Conclusions:
- Understanding fluid balance in neonatal CHF is critical.
- Careful consideration of diuretic risks and benefits is essential for optimal patient outcomes.
Abstract:
Congestive heart failure is characterized by extracellular fluid volume expansion, increased venous filling pressure, and paradoxal renal sodium retention. Although diuretics remain invaluable agents to lower venous pressure in congestive heart failure, they also carry the risk of further compromising cardiac output and inducing severe adverse effects. This article reviews the pathophysiology of body fluid homeostasis in neonates with congestive heart failure, and discusses the adverse effects associated with the use and abuse of diuretics.
