❓ Frequently Asked Questions About Banfield Anesthesia Calculator

How much anesthetic does my pet need?
The amount depends on your pet's weight, species, ASA status, and procedure type. For a 20kg dog undergoing minor surgery: Premedication (Acepromazine 0.4mg + Hydromorphone 2mg IM), Induction (Propofol 40-80mg IV to effect), Maintenance (Isoflurane 1.5-2%). Use our calculator above for exact dosages.
What is the Banfield anesthesia protocol for dogs in 2026?
Standard 2026 Banfield protocol for healthy dogs: Premedication - Acepromazine 0.02mg/kg + Hydromorphone 0.1mg/kg IM. Induction - Propofol 2-4mg/kg IV. Maintenance - Isoflurane 1.5-2%. Fluid rate - 10 mL/kg/hr. Our calculator customizes this for your patient.
What is the correct fluid rate during anesthesia?
Standard fluid rates: ASA I-II patients: 10 mL/kg/hr. ASA III: 5-7 mL/kg/hr. ASA IV-V: 3-5 mL/kg/hr. Cats typically receive lower rates than dogs. Our calculator provides rate based on ASA status.
What monitoring is required during veterinary anesthesia?
Essential monitoring includes: Heart rate (60-120 bpm dogs, 100-200 bpm cats), Respiratory rate, Blood pressure (MAP >60 mmHg), SpO2 (>95%), ETCO2 (35-45 mmHg), Temperature. Frequency: ASA I-II every 10 min, ASA III every 5-7 min, ASA IV-V continuous.
How do I adjust anesthesia for geriatric or high-risk pets?
For geriatric/high-risk patients: Reduce premedication doses by 20-30%, use reversible agents when possible, choose alfaxalone for induction, maintain with lower inhalant concentrations, increase monitoring frequency, and extend recovery monitoring.
