Summary
Intracecal fluid administration in ponies can maintain hydration and electrolyte balance. However, this method may lead to complications such as peritonitis and electrolyte disturbances.
Area of Science:
- Veterinary Medicine
- Equine Physiology
- Gastrointestinal Research
Background:
- Intracecal fluid administration is a potential route for hydration and electrolyte management in horses.
- Understanding the physiological effects and potential complications is crucial for clinical application.
Purpose of the Study:
- To evaluate the effects of intracecal crystalloid solutions on physiological parameters in healthy ponies.
- To assess the impact on hydration, electrolyte balance, and identify associated complications.
Main Methods:
- Six healthy ponies received two different fluid solutions via percutaneous cecal catheters.
- Parameters monitored included body weight, complete blood count (CBC), packed cell volume (PCV), plasma protein, abdominal fluid, and serum electrolytes (Na, Cl, K, P, Ca, BUN, creatinine, TCO2).
- Fractional clearances (FC) of Na, Cl, K, and P were calculated.
Main Results:
- Solution 1 increased fractional clearance of sodium (FCNa) and chloride (FCCl), while decreasing fractional clearance of potassium (FCK) and blood urea nitrogen (BUN).
- Solution 2 increased FCNa and serum phosphorus (P), and decreased PCV.
- All ponies developed peritonitis; complications included catheter issues, diarrhea, laminitis, and hypocalcemia.
Conclusions:
- Intracecal administration of crystalloid solutions can support hydration and electrolyte balance in ponies.
- The procedure is associated with significant complications, including peritonitis and electrolyte derangements, necessitating careful consideration.
