Sea Turtle Physical Examination: Part 2

Part of a unique series on sea turtle veterinary medicine and wildlife rehabilitation, this article explores many components of the sea turtle physical exam. Evaluation of the shell is discussed in both cheloniids and leatherbacks (Dermochelys coriacea) as well as assessment of the cardiopulomonary system, skin, long bones and joints, cloaca and tail. Evaluation of the coelom by inguinal palpation is described as well as measurement of body temperature. Specialized testing such as neurologic and in-water examinations are also described. Common physical examination findings like fibropapillomas in green turtles (Chelonia mydas) and epibiota in loggerhead turtles (Caretta caretta) are also discussed. LOGIN to view references.

Omega-3 Fatty Acids and Atherosclerosis in Birds

What is atherosclerosis?

Atherosclerosis is characterized by fibrous plaques between the tunica intima and the internal elastic lamina of the vasculature. The heart, great vessels, and peripheral vessels of all sizes can be affected. Atherosclerosis begins with the formation of fatty streaks, which can eventually progress into fibrous plaques and complicated lesions…

Cardiac Disease in Ferrets

Cardiac disease is common in middle-aged and older domestic ferrets. Dilated cardiomyopathy is the most common heart disorder in older ferrets, however hypertrophic cardiomyopathy and valve conditions also occur in the ferret. Clinical signs range from asymptomatic disease to fulminate heart failure with problems such as anorexia, weakness, and dyspnea.

Presenting problem: Dyspnea in Rabbits

It is critical to approach the dyspneic rabbit quietly, carefully, and gently. Many rabbits with respiratory disease are unstable upon presentation, given the stress of their condition compounded by the stress of transport and the strange smells, sights and sounds of the veterinary clinic. In many cases, it is prudent to delay handling the patient. Transfer the rabbit to…

How to Verify Life (and Death) in Reptiles

Nowhere is the mystery of life and death more apparent than when dealing with reptiles.

Detecting the reptile heart rate: Even in the active, healthy reptile the stethoscope is generally a useless piece of equipment. The presence of scales or the shell makes auscultation of the heart difficult, if not impossible, in many instances. Therefore ancillary testing such as ultrasonography or electrocardiography is required.

Heatstroke in Exotic Companion Mammals

Heatstroke is the most severe form of heat-related illnesses. In this life-threatening condition, the body is unable to dissipate heat load at a rate that accommodates excessive heat levels.

Begin treatment immediately once heatstroke is suspected. Intensive care is aimed at reducing body temperature while supporting organ function. A variety of techniques can be used to lower core body temperature. Administration of intravenous or intraosseous fluids is a popular internal cooling technique that also serves to support organ function…

Cardiopulmonary-Cerebral Resuscitation in Birds

The basic principles of cardiopulmonary-cerebral resuscitation may be applied to birds. The prognosis for respiratory arrest, especially when caused by isoflurane anesthesia overdose, is good. Cardiac arrest in birds carries a poor prognosis, because direct compression of the heart is not possible due to the overlying sternum. Also, because birds lack a diaphragm, closed-chest compressions cannot utilize the thoracic pump mechanism to increase overall negative intrathoracic pressure. Therefore early recognition of cardiovascular instability is particularly important in avian species.

Measuring Avian Blood Pressure

Arterial blood pressure measurement is an important tool in the management of the critically ill bird. Systolic blood pressure is the pressure exerted against the blood vessel wall during contraction of the heart. Although direct arterial pressure measurement is ideal, it is not commonly used because of the need for specific technical skill, invasive nature of the procedure, and cost of equipment.
