Acute renal failure in horses often stems from blood flow issues or toxins. Current treatment focuses on supportive care, correcting imbalances, and addressing the root cause, with dopamine and mannitol no longer advised.
Area of Science:
- Veterinary Medicine
- Equine Health
- Nephrology
Background:
- Acute renal failure (ARF) in horses is a significant clinical concern.
- Causes are typically prerenal (e.g., hemodynamic insults) or renal (e.g., nephrotoxic insults).
- Effective management strategies are crucial for improving patient outcomes.
Purpose of the Study:
- To summarize current understanding and clinical management of acute renal failure in horses.
- To highlight the importance of supportive care and addressing underlying causes.
- To update recommendations regarding specific pharmacological interventions.
Main Methods:
- Review of current veterinary literature on equine acute renal failure.
- Analysis of established and emerging treatment protocols.
- Synthesis of expert opinion on diagnostic and therapeutic approaches.
Main Results:
- Acute renal failure in horses is commonly linked to hemodynamic or nephrotoxic factors.
- Primary management involves supportive care, including fluid therapy and correction of metabolic disturbances.
- The use of dopamine and mannitol for enhancing renal blood flow and urine output is no longer recommended.
Conclusions:
- Supportive care is the cornerstone of managing equine acute renal failure.
- Identifying and reversing the underlying cause is critical for successful treatment.
- Veterinarians should avoid using dopamine and mannitol in ARF cases due to lack of efficacy and potential harm.

Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
Acute Kidney Injury I: Introduction
Renal Failure: Dose Adjustments
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...
