How to inject furosemide into a cat? - briefly

To administer furosemide to a cat intravenously, ensure the drug is properly diluted with sterile saline or another appropriate solution. Insert the needle gently into the vein, typically in the cat's forelimb, and slowly inject the diluted furosemide over at least one minute to avoid discomfort or adverse reactions.

How to inject furosemide into a cat? - in detail

Injecting furosemide into a cat requires careful attention to detail and adherence to proper procedures to ensure both the safety of the animal and the efficacy of the treatment. Furosemide is commonly used in veterinary medicine to treat conditions such as heart failure, kidney disease, and hypertension. Here is a detailed guide on how to administer furosemide to a cat:

  1. Preparation: Begin by gathering all necessary equipment and materials. You will need:

    • Furosemide solution (usually 20 mg/mL or 40 mg/mL)
    • Sterile syringe and needle (typically a 25-gauge, 1-inch needle)
    • Alcohol swabs or cotton balls with isopropyl alcohol
    • Latex gloves for personal protection
    • A calm environment to minimize stress on the cat
  2. Calculation of Dose: The dosage of furosemide for cats is typically 2-4 mg/kg, administered subcutaneously (under the skin) or intravenously. Consult with your veterinarian for the precise dosage based on the cat's condition and weight. For instance, if a cat weighs 5 kg and the prescribed dose is 3 mg/kg, you would calculate: [ 5 \text{ kg} \times 3 \text{ mg/kg} = 15 \text{ mg} ] Using a 20 mg/mL solution, you would need: [ \frac{15 \text{ mg}}{20 \text{ mg/mL}} = 0.75 \text{ mL} ]

  3. Drawing Up the Medication:

    • Draw air into the syringe equal to the volume of medication needed (e.g., 0.75 mL).
    • Insert the needle into the vial of furosemide and push the plunger to expel the air into the vial.
    • Withdraw the correct amount of medication into the syringe.
  4. Site Selection: For subcutaneous injection, select a site with loose skin, such as the scruff of the neck or the dorsal aspect (back) between the shoulder blades. Avoid areas with bones, muscles, or previous injections.

  5. Preparing the Injection Site:

    • Gently restrain the cat to prevent sudden movements.
    • Clean the injection site with an alcohol swab to remove any dirt or oils that could contaminate the needle. Allow the area to dry naturally.
  6. Administering the Injection:

    • Hold the syringe like a pencil, with your dominant hand.
    • Lift the skin at the injection site between your thumb and index finger to create a tent-like structure.
    • Insert the needle quickly and smoothly at a 45-degree angle into the tented area, ensuring the entire length of the needle is inserted under the skin.
    • Aspirate (pull back) slightly on the plunger to check for blood; if blood appears, you have hit a blood vessel and should withdraw the needle and select another site.
    • Once you are sure you are in the subcutaneous space, slowly depress the plunger to administer the medication.
  7. Post-Injection Care:

    • Remove the needle from the skin and apply gentle pressure with a cotton ball or gauze if any bleeding occurs.
    • Dispose of the syringe and needle safely in an appropriate sharps container.
    • Monitor the cat for any adverse reactions, such as swelling at the injection site, difficulty breathing, or lethargy. If any of these occur, contact your veterinarian immediately.
  8. Documentation: Record the date, time, and amount of medication administered in the cat's medical records for future reference and to maintain continuity of care.

By following these detailed steps, you can ensure that furosemide is administered safely and effectively to a cat, optimizing the therapeutic outcome while minimizing potential risks.
