Recommendations for Anesthetic Fluid Rates

  • Provide the maintenance rate plus any necessary replacement rate at < 10ml/kg/hr
  • Adjust amount and type of fluids based on patient assessment and
  • The rate is lower in cats than in dogs, and lower in patients with cardiovascular and renal disease
  • Reduce fluid administration rate if anesthetic procedure lasts > 1 hr
  • A typical guideline would be to reduce the anesthetic fluid rate by 25% q hr until maintenance rates are reached, provided the patient remains stable

Rule of thumb for cats for initial rate: 3 mL/kg/hr
Rule of thumb for dogs for initial rate: 5 mL/kg/hr
