Magnesium sulfate is indicated as an adjunctive method in animals that are already unconscious under a surgical plane of general anesthesia.

INDICATIONS

Magnesium sulfate is used as an adjunctive agent to ensure cardiac arrest after the animal has been rendered unconscious by other means, such as an overdose of barbiturates or a penetrating captive bolt.

• Prior Anesthesia is Mandatory: The primary indication requires that personnel must first achieve and confirm a deep surgical plane of anesthesia to ensure a humane process.
  • When Barbiturates are Unavailable: It is an option, particularly for large animals like livestock and horses, where pentobarbital (the preferred euthanasia drug) might be unavailable.
  • For Cost Considerations: In certain situations or regions where the cost of barbiturates is prohibitive, magnesium sulfate may be used as a more economical alternative, but always with prior anesthesia

ADMINISTRATION

• – Veterinary guidelines emphasize that magnesium sulfate should never be used as the sole agent for euthanasia in a conscious animal.
• – Only administered after the animal has been rendered completely unconscious through other appropriate methods, such as deep anesthesia or physical stunning.
• – Adherence to established guidelines and ethical practices is paramount in veterinary euthanasia.
