[Two cases of tetany in the horse (author’s transl)].

The research studies tetany, a neuromuscular disorder causing muscle spasms, in horses, more specifically in two nursing thoroughbreds. The study also looks into the effects of calcium borogluconate and magnesium chloride as a therapeutic intervention.

Case Identification

• The researchers present two instances of tetany in thoroughbred horses. Both horses were mares and were of eight and thirteen years of age.
• Both the mares had had a foal recently, one being four weeks old while the other one seven weeks old. This information could potentially serve as significant because the postpartum period could affect the physiology of the horses, leading to conditions such as tetany.
• The mare’s reproductive cycle was also noted; they were in heat and were supposed to mate.

Findings

• In both cases, the calcium level in the serum had dropped significantly. In one case, it dropped to 4.0 mg per ml and in the other, it was 5.4 mg per ml. This deficiency in calcium levels could be the leading cause of tetany, as calcium is crucial for muscle contractions and nerve signals.
• The magnesium level was also noted as 1.0 mg and 1.9 mg per 100 ml. Magnesium too plays a critical role in nerve transmission and muscle contraction.

Intervention and Outcome

• Both animals were administered an intravenous infusion of calcium borogluconate and magnesium chloride, subsequently responding positively. The fact that horses responded well to calcium and magnesium replacement indicates that deficiencies of these minerals could have led to the onset of the tetany.
• Furthermore, one of the mares was also given 10 1. of physiological saline severally. Saline is often used to replenish fluids and electrolytes. This suggests further complexity in the case, perhaps a possibility of dehydration or electrolyte imbalance.

Implications

• This study provides vital data about the manifestation of tetany in nursing thoroughbred horses. It also suggests a potential link between the condition and a deficiency in calcium and magnesium serum levels.
• Moreover, the research offers important lessons on suitable therapeutic strategies for such cases using calcium borogluconate, magnesium chloride, and even a simple measure like saline administration for fluid and electrolyte balance.
