This handout is supplemented by two appendices as well as sections that list further reading and online resources that can be included or excluded to best meet individual client needs.

Article

Full-spectrum lighting is essential for reptile health. Sunlight – whether natural or simulated in a vivarium – is a vital resource. For decades, the focus has been upon provision of the correct spectrum and intensity of ultraviolet-B (UVB), primarily to enable vitamin D3 synthesis in the skin. More recently, the importance of all wavelengths found in daylight – from full sunlight to dim light filtering through deep shade – is increasingly recognized. UVB, ultraviolet-A (UVA), visible light and short-wavelength infrared (IR-A) all play important roles. This article reviews the relationship between vitamin D and lighting before exploring general guidelines on UV lights as well as specific advice on choosing bulbs, including recommendations on lamps to avoid.

A common misconception is that true emergencies in reptile medicine do not exist. While it is true that most emergencies are an acute manifestation of a chronic disease, by the time the owner notices a problem an emergency may exist. Some common, true, acute-onset emergencies include trauma, vomiting, prolapse, seizures, tremors, obstructive dystocia, and severe dyspnea. Proper triage is critical when treating exotic animal patients and a complete history is vital to help determine a list of differential diagnoses. A physical examination should be performed, but initially it may be only visual or extremely limited if the patient is unstable. Stabilization should be the priority; then additional tests or procedures can be performed once the patient is more stable.

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.

Reptile dentition tends to be relatively uniform with a simple, conical shape. Most reptile teeth are loosely attached with the dental attachment most superficial in acrodontic species. Tooth loss and replacement is a normal occurrence in reptile species with pleurodont dentition, which includes snakes, and many lizards. Take special care when handling reptiles with acrodont dentition as teeth will not be replaced when infected or fractured. Additionally, periodontal disease is common in captive lizards with acrodont dentition such as bearded dragons and chameleons. Periodontal disease is an insidious condition. As plaque formation builds and gingivitis worsens, many reptiles will continue to eat. The owner may not observe problems until disease is quite advanced. Feeding lizards an unnatural, soft diet is believed to promote plaque development and the development of periodontal disease.

Diagnostic and therapeutic procedures cannot be administered until you and your staff can safely handle and restrain the turtle or tortoise patient. Many chelonian patients presented to the veterinary hospital are ill and therefore their temperament and strength level can be reduced. Normal, healthy chelonians tend to be bright, alert and very strong, making them extremely challenging to restrain. Gaining control of the head can be particularly difficult, however multiple techniques have been described.

The turtle ear is a simple structure that sits caudoventral to the eye covered by a large scale called the tympanic scute. As in many reptiles, the external ear is absent in chelonians. The tympanic membrane sits flush against the skin just underneath the tympanic scute. There is one ossicle, the columella, which crosses the large tympanic cavity to insert medially on the oval window of the cochlea. A narrow Eustachian tube connects the middle ear to the oropharynx.

Aural abscesses are well-encapsulated, caseous plugs that slowly develop until it fills the tympanic cavity. The cause of aural abscessation is not completely understood…
