Acute renal failure in horses.

The research article focuses on acute renal failure (ARF) in horses, identifying its major causes and discussing the most effective treatment strategies, including supportive measures and treatment of underlying causes, but rejecting the use of dopamine and mannitol for stimulation of renal blood flow and urine output.

What is Acute Renal Failure?

• Acute renal failure (ARF) is a serious medical condition that occurs when the kidneys suddenly cease to function properly.
• In horses, it’s commonly caused by either hemodynamic or nephrotoxic insults.
• Hemodynamic factors refer to anything that negatively affects the blood flow to the kidneys, while nephrotoxic factors involve substances that damage the kidney tissue directly.

Managing Acute Renal Failure

• The research found the main treatment for ARF in horses to be largely supportive. This includes:
  • Correction of fluid deficits: This involves administering fluids to the horse to restore healthy hydration levels and ensure the proper function of the kidneys.
  • Tackling electrolyte and acid-base disturbances: Horses with ARF often have imbalances in electrolytes and may suffer from metabolic acidosis, requiring specific interventions to restore balance.
• Another crucial aspect of the treatment plan is identifying and treating the underlying cause of ARF. This could involve removing a blocker preventing proper blood flow to the kidneys or discontinuing a medication that is causing nephrotoxicity.

Rejection of Dopamine and Mannitol

• The use of dopamine and mannitol, previously recommended for promoting renal blood flow and urine output in horses with ARF, is no longer advocated according to this research.
• This implies that these treatment strategies might not be effective or beneficial in the management of ARF in horses. Their rejection suggests the necessity to focus on other, more effective treatment options and directions.
