Pain Definition, Recognition and Management!

What is Pain?

Pain is "an unpleasant sensory and emotional experience associated with actual or potential tissue damage" (Weiner's Pain Management, 7th edition). 

It seems obvious what pain is for humans.  Pain in companion animals can be as obvious as in people, however, it also can be very challenging to recognize in some individual pets.  We have found significant differences in the way pain or discomfort may be demonstrated between cats and dogs, and even individuals within cat and dog breeds.  It would be extremely helpful if we could communicate more clearly with pets.  It is very important to look (observe your pets' behavior), listen, touch  and be empathetic, to better understand companion animals in regard to pain.

The secret to better recognition of pain is better observation and improved understanding of species and individual differences.  The signs of pain may be very subtle and important.  Dr. Kressin understands how it feels to have a pet with pain. A feeling of helplessness.  Pain is a shame and Dr. Kressin never wants to be to blame.

  • Recognizing pain is not always as easy as in the photos displayed above! 

    The recognition of pain can be simple, or very difficult.  The effort is very worthwhile
    regardless!

    Research has demonstrated that chronic pain can be detrimental to the patient.  
    Chronic pain can create a "stress response" associated with elevations of cortisol;
    an internal chemical.  The stress response can reduce the patient's immune response,
    contributing to infection, slower healing, or the inability to heal.  Chronic pain
    is unfortunate because the pain response can remain long after the injury has healed.
    Excellent Observation of your pet is key to recognition of potential pain:
  • Physical activity
  • Oral activity
  • Sleep cycle unusual
  • Posture
  • Facial Grimace or Stare
  • Vocalization
  • Human interaction
  • Eyes, Ears, Breathing

    We work as a "team" to listen, observe, touch gently and help companion animals in every way possible.  Dogs are typically more vocal, however, some dogs hide pain.  Cats more typically mask their pain by hiding.

Pain Management

We prefer to prevent pain where we can, and minimize/control pain if we cannot prevent it.

A multimodal approach (multiple methods) to treatment is best.
Pain management is unquestionably a topic of great interest in veterinary medicine today. The concept of pain management encompasses: pain prevention, minimization of nauseous stimulation and treatment. My veterinary team is responsible for the management of our patient's comfort, and we find these efforts very rewarding.

Preemptive analgesia (preventing pain) is a function of balanced anesthesia. Pre-anesthesia medications and the route of administration are selected based on the patient's age, health status and temperament. These premedications provide sedation, analgesia (pain relief) and patient safety. The opiates drugs (hydromorphone and morphine) and low dosages of alpha 2 adrenergics (medetomidine or Domitor) are very useful premedications for preemptive analgesia (minimizing or avoiding pain).

Maintenance analgesia can be part of balanced anesthesia, or independent of anesthesia. Continuous infusions of analgesics (pain medications), also called constant rate infusions (CRI's), are extremely effective tools of pain management. Opiate drugs are the primary CRI's employed, however, ketamine and lidocaine have also been very effective. Combination CRI's have shown to be optimally effective. Morphine, lidocaine with ketamine (MLK) and fentanyl, lidocaine with ketamine (FLK) are extremely effective and versatile in pain management. The medications are carefully dosed for each patient and infused precisely using intravenous pumps and infusion syringes. With appropriate training and experience, these techniques have become fundamental procedures for pain management.

The uses of local or regional "nerve blocks" have proven to be excellent adjunct procedures for analgesia as well as balanced anesthesia.  Again, training and experience are required to ensure that these procedures are performed safely. Knowledge of appropriate dose calculations and technique are imperative.

Nonsteroidal anti-inflammatory medications {NSAID's (Deramax, Metacam, Rimadyl and others)} have additionally been useful for mild pain management. Their uses in combination with opiate drugs have been particularly effective in pain management protocols.  It is always very important to address the patient's hydration status, as well as, kidney and liver function prior to using NSAID's.

I have found transdermal fentanyl (cats or dogs), and transmucosal buprenorphine (cats), particularly useful for pain management.

Hydrotherapy, massage therapy, spinal manipulation and veterinary acupuncture are all modalities to help manage pain.  Where does the veterinary team start?

Continuing education is the essential first step in understanding the pathways of pain recognition and management. I joined the International Academy of Veterinary Pain Management (IVPAM) near the organization's inception, and have enrolled my technicians as members annually. This organization has an active meeting schedule and courses for continuing education.

Pain management has become very rewarding professionally for me. The benefits in patient safety and comfort, as well as, client satisfaction, are clear.

Pain Management is Important!

Pain is a useful warning signal in the early period (acute) following injury or surgery.  Longer periods (chronic) of pain can be very harmful. Recent research has shown that balanced anesthesia with appropriate analgesia can minimize, and even prevent pain. This minimization and prevention of acute pain can eliminate chronic pain all together. Chronic pain is un-necessary, harmful and at times, avoidable.  I promise to take a proactive approach to pain management with your pets!

Dr. Kressin Continues his Education.

As a veterinary dental specialist, Dr. Kressin has had training beyond veterinary school training in anesthesia and pain management.  Advances in veterinary anesthesiology and analgesia are continually improving.

Dr. Kressin uses the Veterinary Anaesthesia and Analgesia journal as a resource in his practice.  The pain management position of the American College of Veterinary Anesthesiologists is also a source of guidance.
