Anesthesiology & Pain Management

The field of invertebrate medicine is in its infancy. Traditionally veterinary interest in invertebrates has centered on the control of species that are involved in vertebrate disease processes. The husbandry and medical care of captive invertebrates has typically fallen to scientists and hobbyists, with very little veterinary involvement. Now, as many institutions and private individuals maintain large invertebrate collections, a genuine interest exists in advancing the quality of medical care available for these taxa.

What should electronic anesthetic monitoring systems check for?

All veterinary team members play a role in providing patients safe anethetic experiences.

Anesthesia is a vital inclusion in any clinic's medical practice, but it does come with risks. By avoiding these common mistakes, your patients will receive a safer anesthetic experience.

A Q&A with Dr. James Gaynor.

Don't assume dental procedures are of little anesthetic risk.

The results of a University of Wisconsin randomized controlled trial assessing the efficacy of retrobulbar analgesia on the control of postoperative pain in dogs undergoing enucleation was recently published.

A common source of chronic pain in pets.

The use of a modified spirometric monitoring system for anesthetized equine patients was recently evaluated.

When assisting with anesthesia and surgery, our technician sets her cell phone, which is in her pocket, to vibrate every five minutes.

Kansas City -- Of all the regulatory issues veterinarians face, the use and storage of controlled substances can be the most contentious.

Another possible cause of abnormal capnograph readings.

A recent study looked at the effects of gabapentin for use as adjunctive perioperative pain control in dogs.

We already know that the way we each perceive pain will be different depending on our past experiences. The way we respond to that pain also varies from person to person. These two points make recognizing and treating pain difficult, especially in regards to our veterinary patients.

There are a wide variety of pain management techniques. I hope to cover a few here. Some of the different areas we will cover are injectable analgesia, epidurals, wound soaker catheters, local blocks, NSAIDs, and alternative methods. Each group will be expanded upon, with specific examples.

The biggest concern with all exotic animals under anesthesia is hypothermia. Other main concerns include airway access, intravenous access, pain management, and hemorrhage.

Due to the fact that critical patients are more fragile than stabile patients, they require special nursing care. The same is true of these special patients under anesthesia.

Veterinary technicians are the veterinary hospital's mainstay when it comes to carefully and successfully anesthetizing critical patients. A large number of elderly canine and feline patients are affected by cardiac disease, and knowledge of how to safely monitor, anesthetize, and problem solve cardiac patients makes for a less stressful anesthesia for both the patient and technician.

Monitoring, for these purposes will consist of checking vitals on a regular basis. The vitals being monitored may be changed based upon the patient's status and the procedure performed. By watching for changes in trends we are able to catch and potentially stop a crisis from happening..

The most common application of nutrition and nutraceuticals in the world of pet pain is among chronic, maladaptive pain patients... These are the patients who benefit the most from a multi-modal, multi-target approach to their pain relief. In order to provide the very best care for these patients so as to achieve the best outcome on their behalf, we need to adhere to a few simple strategies.

For many years, chronic pain in dogs and cats was either tolerated as a necessary evil, or was considered a reason for euthanasia to relieve the pet from unnecessary suffering. With the development of contemporary pharmaceuticals and technology, more pets are able to live reasonably comfortable lives despite chronic conditions that could have previously caused unrelieved suffering.

Myofascial Pain is a rarely recognized pain generator for both acute and chronic pain in dogs. It is both defined by and diagnosed by the presence of muscle pain originating from myofascial trigger points (MTrPs) within the muscles.

A new strategy to extend the duration of local anesthesia may markedly help patients with moderate to severe surgical injury. Implantation of a catheter into the surgical wound site prior to closure allows repeated or continuous infusion of local anesthetics into the affected area.

An "epidural" is defined as an injection into the epidural space, most commonly performed at the lumbo-sacral junction. It was originally used in animals to avoid the use of general anesthetics in aged debilitated and shocky animals back when anesthetic choices were more limited and more dangerous than the options we have today.

Cats add an extra dimension of difficulty when it comes to assessing pain in animals. Listed below, are just some of the "new onset pain behaviors" shown by cats in acute severe pain. (adapted from Karol Matthews's excellent chapter in the Veterinary Clinics of North America Small Animal Management of Pain, July 2000 Vol 30 issue entitled: Pain Assessment and General Approach to Management). However, the observer must be very astute if they are to pick up signs of moderate or mild pain, and are exhibited not by the onset of new behaviors, but rather absence of usual behaviors.

The good news is that veterinary clinicians are faced with a staggering array of possibilities to prevent and manage pain in surgical patients. The bad news is that veterinary clinicians are faced with a staggering array of possibilities to prevent and manage pain in surgical patients.

When planning for the recognition, prevention, and treatment of pain in animal patients it is useful first to decide whether we are dealing acute pain or chronic pain. These two categories of pain patients have some needs that overlap, but our approach to them needs to be different as we articulate our middle-term and long-term plans.

Rapid advances are being made in understanding the neurobiology of pain, which in turn reveal potential new targets for prevention and treatment.

There are many medical conditions that can be quite painful, and are often forgotten in our pursuit to cure the disease. Common among these are eye pain, urinary cystitis, pancreatitis, renal uroliths, anal sac infection and acute moist dermatitis.

Local anesthetics were once a mainstay of pain management in veterinary medicine, and may now be one of the most under-utilized modalities. Administered locally or regionally, they are the only modality that renders complete anesthesia to a site, i.e. no transmission of nociceptive impulses as long as the drug exerts its effect.
