A dedicated anesthetist should be assigned to monitor every patient during the perianesthetic period. The anesthetist is fundamental to patient safety because she assures the patient is not aware, not moving, and not in pain, all while maintaining stable anesthetic depth. A deep plane of anesthesia can lead to hypoventilation and hypoxemia, reduced cardiac output, hypotension, inadequate tissue perfusion, central nervous system (CNS) depression, and prolonged recovery. This review article first explores the stages of anesthesia and then discusses assessment of anesthetic depth in exotic companion mammals, birds, and reptiles.

Article Case Study

Lafeber Company was proud to sponsor the 2020 Association of Exotic Mammal Veterinarians Student Case Report Contest. Veterinary students from all over the world were encouraged to write a 2-page case report about an exotic companion mammal seen at their college of veterinary medicine or during a clinical experience. Submissions closed in March and judges from the Research Committee evaluated the 15 case reports received from eight countries. Judges were blinded to the students, mentors, co-authors, and institutions at which the cases were seen. Read the brief summaries of each winning case report.

What determines the viral host range?

One of the critical determinants of viral host range is the interaction between the coronavirus spike (S) protein (Fig 1) and the host cell receptor. Angiotensin-converting enzyme 2 (ACE2), a receptor for the attachment and uptake of the coronavirus that caused Severe Acute Respiratory Syndrome (SARS-CoV-1), is widely expressed […]

Article Case Study

A 3-year old intact male guinea pig was presented on emergency for suspected bloat and with a history of chronic hair loss. Clinical examination revealed non-pruritic symmetric truncal alopecia, thin skin, severe cachexia, and an abdominal fluid wave. Alkaline phosphatase, alanine transaminase, aspartate aminotransferase, gamma-glutamyl transferase, leukocytes (neutrophils), bilirubin, and serum cortisol were markedly elevated. Abdominal ultrasonography revealed peritoneal effusion, cholestasis, and cholelithiasis. Hyperadrenocorticism was diagnosed based on…

Article Case Study

Two guinea pigs suspected of having hyperthyroidism based on weight loss, presence of a cervical mass, and elevated total thyroxine (TT4) levels were confirmed to have active thyroid masses via scintigraphy with Technetium-99 and treated with radioactive iodine therapy (I¹³¹). Both patients responded initially with weight gain and a decrease in the TT4. The purpose of this case series is to describe the use of scintigraphy to aid in confirming a diagnosis of hyperthyroidism, as well as to show the benefits and effectiveness of using radioactive iodine therapy (I¹³¹) to treat hyperthyroidism in guinea pigs in order to provide the best treatment protocol.

Even the most steadfast and seasoned veterinary anesthetist can find themselves intimidated by exotic animal patients. Standard veterinary anesthesia monitors are not designed to read the extremely high (or extremely low) heart rates and respiratory rates of some exotic animal patients. Despite these challenges, valuable information can be gathered from monitoring tools as well as hands-on techniques. Essential vital signs, such as heart rate and rhythm, respiratory rate and depth, body temperature, and mucous membrane color should all be evaluated.

Arterial blood pressure is a function of heart rate, blood volume, stroke volume, and arterial compliance. Indirect arterial blood pressure is most commonly measured by Doppler ultrasound or non-invasive oscillometric monitors. What are the limitations of indirect blood pressure measurements in exotic animal patients? How is this technique unique in exotic companion mammals when compared to dogs and cats? How is this technique performed in birds and can this procedure be used in reptiles?

Article

The guinea pig is a gentle, highly social rodent, that commonly serves as a companion animal and an experimental model in North America and Europe. Food preferences are established early in life, and a guinea pig can refuse to eat if their food type or presentation is changed. For this reason, small mammal veterinarians recommend exposing juvenile guinea pigs to a variety of chows and vegetables. Guinea pigs also do not tolerate environmental changes well. When exposed to something perceived as dangerous, the response of the guinea pig is generally to freeze, or less commonly flight.

Article

The guinea pig is a popular companion animal and a common research model. Guinea pigs are useful in reproductive studies because they share many reproductive traits with human beings. This article reviews anatomy and physiology of the guinea pig reproductive tract and summarizes some clinically significant medical problems.

Article

Guinea pigs are small, docile rodents, that must be approached with great care. Accurate evaluation of patient health status requires a thorough history, careful visual examination, and a detailed physical examination. Like most prey species, the guinea pig frequently hides signs of pain and illness. To improve clinical success, take measures to minimize stress by maintaining the animal in a quiet exam room and approaching the patient in a slow, quiet manner. The hospitalized guinea pig can also benefit greatly from the presence of a bonded cage mate. Monitor appetite and eliminations carefully in the guinea pig, and offer the same diet as fed in the patient’s home whenever possible as guinea pigs establish strong food preferences early in life.

Article

The approach to analgesia and sedation in exotic companion mammals faces special challenges, including small patient size and unique features of the prey species mentality. Recognition of pain is more difficult in rabbits and rodents because many small mammals are very good at hiding the signs of pain commonly observed in predator species. Instead pain in a rabbit or rodent is often inferred from the patient’s clinical condition as well as the absence of normal behaviors. The diagnostic and therapeutic plan frequently requires some form of chemical restraint in exotic mammal medicine. When compared to general anesthesia, sedation is a safer option for the debilitated or critically ill small mammal.

Most small herbivores like the rabbit, guinea pig, and chinchilla possess a simple, non-compartmentalized stomach paired with a large cecum and colon. To feed the small herbivore gastrointestinal tract, provide insoluble dietary fiber to stimulate gut motility and maintain gastrointestinal health. A balanced small herbivore diet contains adequate fiber (minimum 25%), minimal starch, and moderate protein levels. Among small herbivorous non-ruminants, the gastrointestinal tract of the rabbit is the most specialized and this manuscript will focus on unique features of this species’ anatomy and physiology.

In no way, should the reader believe the use of tracheostomy tubes is common in exotic companion mammals like the guinea pig. This technique is exceedingly rare. However given the frequent lack of airway control and the particular concerns when anesthetizing guinea pigs, those concerned with emergency and critical care should be aware of this technique as a “back up” option. In most instances, use of this surgical approach would mean that the clinician has failed to exercise foresight and planning for their patient’s airway control. Nevertheless anyone who sees rodents, particularly on an emergency basis, should consider compiling a tracheostomy kit and practicing this technique on cadavers.

Are you using epidurals in your practice? The epidural is a neuroaxial technique that provides preemptive analgesia by injecting drug into the epidural space surrounding the spine. Epidurals can be used for abdominal surgery, perineal surgery, and orthopedic procedures involving the pelvic limb or spine. Some opioids can also travel cranially to provide supplemental analgesia for chest and thoracic limb procedures. Epidurals serve as an adjunct to systemic analgesia, and epidural analgesia also reduces the amount of anesthetic drug needed. Epidurals can also shorten recovery time.

Rabbits and rodents may suffer from a wide range of dental problems. Although the vast majority of cases are related injury or to lack of wear and tooth elongation, dental caries, a bacterial plaque-associated disease, may also be seen.

Article

Dental problems in rabbits and rodents are often related to either trauma or lack of normal wear and tooth elongation. When herbivores like rabbits, guinea pigs, and chinchillas receive concentrates, in the form of grain or pellets, with only limited access to hay and natural vegetation this diet provides too little tooth wear to compensate for the natural growth of the teeth.
