Preventive analgesia is based on the idea that it’s more effective to prevent pain than to treat it once it has set in. Instead of waiting for the animal to experience pain, analgesics are administered before, during, and after a procedure or surgery to prevent the sensation of pain. This strategy aims to avoid physiological and neurochemical changes associated with pain, which can enhance the overall well-being of the animal and reduce the need for higher doses of analgesics in the future.

Multimodal analgesia, on the other hand, involves using multiple analgesic modalities simultaneously or in combination to achieve better pain control. Rather than relying solely on one type of analgesic, different classes of drugs with complementary mechanisms of action are utilized for a synergistic effect. This may include the use of opioid analgesics, non-steroidal anti-inflammatory drugs (NSAIDs), local anesthetics, and other medications to address various aspects of pain, such as inflammation, central sensitization, and peripheral pain transmission.

Multimodal analgesia can provide improved pain coverage, reduce the need for high doses of a single analgesic, and minimize the side effects associated with using just one type of medication. Additionally, each analgesic modality can act at different stages of the pain process and across various physiological pathways, offering a more comprehensive and effective approach to pain control in animals.

It’s important to highlight that the choice of analgesic modalities used in preventive and multimodal analgesia will depend on several factors, such as the type of procedure or surgery, the animal species, the patient’s health status, and individual considerations.
