Abstract

With over 8300 species described, class Amphibia represents a significant contribution to the diversity of vertebrate life on earth. Amphibians increasingly are being kept as pets, in addition to frequently finding them in zoological and research collections. However routine wellness exams are rarely provided to most pet amphibians, with most animals only presenting to the veterinary clinic as an emergency case when they are ill. The acute onset of a clinical condition requiring emergency care in amphibians is often the result of trauma, infection, metabolic deficiency, toxicity, or a sudden inappropriate environmental change. If multiple animals are affected, each individual must be triaged based on the severity of their clinical signs and risk of deterioration. It is important for clinicians to understand how an amphibian’s unique anatomy and physiology will factor into the clinical approach to emergencies. The expedient collection of a history and husbandry parameters, a systematic physical examination with appropriate selection and execution of diagnostics, and the immediate administration of emergency care will increase the likelihood of a successful outcome.

Blood collection should be considered in the diagnostic evaluation of ill amphibians but may not always be possible. While radiographs are useful for evaluating skeletal disease, respiratory disease, or the presence of a gastrointestinal obstruction (e.g. foreign body), ultrasonography should be considered a standard of care for amphibians for evaluating coelomic viscera and assessing for fluid accumulation. If fluid accumulation noted in the coelom or subcutaneous space then paracentesis followed by cytology, fluid analysis, and aerobic culture should be carried out.

Clinicians must always consider whether pain is present in debilitated amphibians. Decreased activity and feeding behavior, color changes, increased reclusive behaviors, postural changes, and spending more time in atypical locations all have been associated with pain in amphibians. Dermal irritation is often manifested by a wiping behavior with the hindlimb. Amphibians demonstrate a dose-dependent analgesic response to opioids and alpha-2 agonists, such as dexmedetomidine. Always ensure good hydration before using NSAIDS. It is essential to provide nutritional support to debilitated amphibians once dehydration has been corrected, and gavage feeding is often needed initially.

If euthanasia needs to be carried out, several pharmaceutical options are available. Pithing should be carried out with all methods of chemical euthanasia 30 minutes after the loss of reflexes and voluntary movement. Owners should be counseled on the usefulness of submitting deceased amphibians for necropsy with follow up histology and other diagnostic testing where indicated to elucidate causes of mortality. This will be of benefit to other amphibians in their collection.

RACE approval

This program 20-803504 is approved by the American Association of Veterinary State Boards (AAVSB) Registry of Continuing Education (R.A.C.E.) to offer a total of 1.00 CE credits to any one veterinarian and/or 1.00 veterinary technician CE credit. This RACE approval is for Category: Medical using the delivery method of Interactive-Distance. This approval is valid in jurisdictions which recognize AAVSB RACE; however, participants are responsible for ascertaining each board’s CE requirements. RACE does not “accredit” or “endorse” or “certify” any program or person, nor does RACE approval validate the content of the program.
