Acid-base and electrolyte alterations in horses with exertional rhabdomyolysis.

This research article investigates the physical changes in the acid-base and electrolyte levels of seven horses suffering from acute exertional rhabdomyolysis, a muscle-disorder related to intense exercise, where the most consistent abnormality was a lower level of blood chloride (hypochloremia). It found no evidence of metabolic acidosis, a condition where the body produces an excess of acid or the kidneys do not remove enough acid from the body, thus suggesting that sodium bicarbonate, often used in treatment, may not be necessary in all such cases.

Methodology

• The study sampled seven horses diagnosed with acute exertional rhabdomyolysis – a condition triggered by intense exercise that causes muscle cells to break down or die.
• Acid-Base and electrolyte levels were closely monitored in these horses to find any possible consistent abnormalities.

Findings

• The most consistent abnormality discovered across all subjects was hypochloremia. This is a condition where there is an extremely low level of chloride in the blood. Chloride is an important electrolyte that helps maintain proper fluid balance and transmit nerve impulses.
• Contrary to common assumptions, the investigators did not find evidence of metabolic acidosis in any of the cases. Metabolic acidosis is a serious condition where the body either produces too much acid, or the kidneys are not removing enough acid from the body. This disturbs the delicate balance of acid-base in bodily fluids.

Implications

• The absence of metabolic acidosis in these horses suggests that the common treatment method using sodium bicarbonate may not be required in all cases of exertional rhabdomyolysis. Sodium bicarbonate is often used as treatment in medical conditions to neutralize an excessive amount of acid in the blood.
• These findings call for further research into the biochemical changes in horses with conditions like exertional rhabdomyolysis, and highlight the need to reconsider common treatment methods if they are not universally applicable.
