Banfield Anesthesia Calculator

This banfield anesthesia calculator implements a multi-modal approach, considering factors such as species, age, health conditions, and procedure duration.

For a 15kg healthy dog requiring surgery:

• Pre-medication: Acepromazine 0.02-0.05 mg/kg = 0.3-0.75 mg
• Induction: Propofol 4-6 mg/kg = 60-90 mg
• Maintenance: Isoflurane 1.5-2.5% in oxygen

Banfield Anesthesia Chart

Drug Name	Dose (mg/kg)	Concentration (mg/mL)	Patient Weight (kg)	Volume to Administer (mL)
Acepromazine	0.02–0.05	10 mg/mL	Example: 10 kg	0.02 × 10 ÷ 10 = 0.02–0.05 mL
Butorphanol	0.2–0.4	10 mg/mL	Example: 10 kg	0.2 × 10 ÷ 10 = 0.2–0.4 mL
Ketamine	5–10	100 mg/mL	Example: 10 kg	5 × 10 ÷ 100 = 0.5–1.0 mL
Midazolam	0.2–0.5	5 mg/mL	Example: 10 kg	0.2 × 10 ÷ 5 = 0.4–1.0 mL
Propofol	4–6	10 mg/mL	Example: 10 kg	4 × 10 ÷ 10 = 4.0–6.0 mL
Isoflurane	Maintenance: 1–3%	Vaporizer Setting	N/A	Adjust per oxygen flow rates

Banfield Anesthesia Calculation Formula

The formula follows a step-wise calculation using the equation:

Drug Dose = Patient Weight (kg) × Drug Dose Rate (mg/kg)

For a 20kg dog receiving Ketamine (5 mg/kg):

20 kg × 5 mg/kg = 100 mg Ketamine required

How to Calculate Banfield Anesthesia?

• Assess patient weight in kilograms.
• Select appropriate drug combination based on procedure.
• Multiply weight by drug dose rate.
• Convert units if necessary (mg to ml).
• Document calculations in medical record.

For a 30kg dog requiring Hydromorphone (0.1 mg/kg):

30 kg × 0.1 mg/kg = 3 mg Hydromorphone
Convert to ml: 3 mg ÷ 2 mg/ml = 1.5 ml

Senior Cat Dental Procedure:

• Weight: 4.5kg
• Dexmedetomidine: 5 mcg/kg → 22.5 mcg
• Butorphanol: 0.2 mg/kg → 0.9 mg

Young Dog Spay:

• Weight: 25kg
• Hydromorphone: 0.1 mg/kg → 2.5 mg
• Midazolam: 0.2 mg/kg → 5 mg

Rabbit Neuter:

• Weight: 2kg
• Midazolam: 0.5 mg/kg → 1 mg
• Buprenorphine: 0.03 mg/kg → 0.06 mg
• Ketamine: 15 mg/kg → 30 mg

Emergency Dog Surgery:

• Weight: 35kg
• Fentanyl: 5 mcg/kg → 175 mcg
• Propofol: 4 mg/kg → 140 mg
• Isoflurane maintenance: 2%

Geriatric Cat Mass Removal:

• Weight: 3.2kg
• Butorphanol: 0.2 mg/kg → 0.64 mg
• Propofol: 3 mg/kg → 9.6 mg
• Isoflurane maintenance: 1.5%

What is Banfield Anesthesia?

Banfield Anesthesia refers to the comprehensive anesthetic protocols developed by Banfield Pet Hospital, incorporating balanced anesthesia principles, individual patient assessment, and standardized drug calculations to ensure safe and effective sedation or general anesthesia for veterinary procedures.
