Crystalloid and colloid therapy.

Area of Science:

• Veterinary Emergency Medicine
• Equine Critical Care
• Fluid Therapy Research

Background:

• Fluid therapy is vital in emergency medicine.
• Previous recommendations for fluid therapy are being updated.
• New research impacts equine fluid therapy protocols.

Purpose of the Study:

• To inform equine practitioners about evolving fluid therapy recommendations.
• To highlight the importance of avoiding hyperchloremia.
• To discuss updated understanding of colloid efficacy and fluid overload.

Main Methods:

• Review of recent developments in fluid therapy.
• Analysis of the implications of the Starling equation.
• Consideration of research on fluid overload effects.

Main Results:

• Crystalloids with lower chloride concentrations may be preferred.
• The benefits of colloids might be less significant than previously believed.
• Negative impacts of fluid overload on morbidity and mortality are increasingly recognized.

Conclusions:

• Equine practitioners should adapt to new fluid therapy principles.
• Lower chloride crystalloids may be more appropriate.
• Careful fluid administration is essential to minimize adverse effects.
• These principles are likely applicable across species, pending further equine-specific research.
