General anesthesia in horses on fluid and electrolyte therapy

Area of Science:

• Veterinary Medicine
• Anesthesiology
• Equine Surgery

Background:

• Intraoperative fluid management is critical for horses undergoing general anesthesia.
• Maintaining hemodynamic stability and electrolyte balance is essential for patient safety.

Purpose of the Study:

• To provide an updated review of fluid therapy principles for veterinarians administering general anesthesia in horses.
• To discuss the rationale, fluid dynamics, and available fluid options for intraoperative use.

Main Methods:

• Review of current literature on equine fluid therapy during general anesthesia.
• Discussion of physiological principles governing fluid dynamics and electrolyte shifts.
• Analysis of different fluid types, including crystalloids, hypertonic saline, and colloids.

Main Results:

• Crystalloids are commonly used but require large volumes.
• Hypertonic saline and colloids can be effective for volume expansion with smaller doses.
• Electrolyte disturbances (calcium, potassium, sodium) must be monitored and managed.

Conclusions:

• Appropriate fluid selection and administration are vital for successful equine anesthesia.
• Understanding fluid dynamics and electrolyte management improves patient outcomes.
• Veterinarians should consider various fluid types based on individual patient needs and anesthetic protocols.
