OBJECTIVE: To evaluate effects of butorphanol tartrate and buprenorphine hydrochloride on withdrawal threshold to a noxious stimulus in conscious African grey parrots. ANIMALS: 29 African grey parrots (Psittacus erithacus erithacus and Psittacus erithacus timneh). PROCEDURE: Birds were fitted with an electrode on the medial metatarsal region of the right leg, placed into a test box, and allowed to acclimate. An electrical stimulus (range, 0.0 to 1.46 mA) was delivered to each bird's foot through an aluminum perch. A withdrawal response was recorded when the bird lifted its foot from the perch or vigorously flinched its wings. Baseline threshold to a noxious electrical stimulus was determined. Birds then were randomly assigned to receive an i.m. injection of saline (0.9% NaCl) solution, butorphanol (1.0 mg/kg of body weight), or buprenorphine (0.1 mg/kg), and threshold values were determined again. RESULTS: Butorphanol significantly increased threshold value, but saline solution or buprenorphine did not significantly change threshold values. CONCLUSIONS AND CLINICAL RELEVANCE: Butorphanol had an analgesic effect, significantly increasing the threshold to electrical stimuli in African grey parrots. Buprenorphine at the dosage used did not change the threshold to electrical stimulus. Butorphanol provided an analgesic response in half of the birds tested. Butorphanol would be expected to provide analgesia to African grey parrots in a clinical setting. 相似文献

Emergency and critical care principles are similar for all mammals; however, the physiology and natural behavior of rabbits create an animal that is easily stressed and requires specialized handling techniques. This article reviews diagnostic and therapeutic techniques, nutritional support, and pain management for urgent care of pet rabbits. Common differential diagnoses for emergencies are briefly reviewed by the clinical presentation. A table of drug dosages used for urgent care is provided. 相似文献

The psittacine skull is a complex anatomic structure, frequently traumatized but difficult to adequately image with standard radiographic procedures. Multiple views including a ventrodorsal, a lateral, and complementary oblique projections are necessary to fully evaluate potential skull fractures in the avian patient. Magnification radiography is a relatively easy procedure that aids the review of small osseous structures. Familiarity with psittacine skull anatomy greatly facilitates radiographic interpretation of cranial trauma. 相似文献

There are numerous causative agents of avian conjunctivitis, many of which are associated with systemic disease. A thorough evaluation of the patient's history and habitat is mandatory, and a complete physical examination and ophthalmic examination are required. The owner should be informed at the initial visit that an orderly sequential approach for obtaining diagnostic specimens is required and that a protracted course of treatment may be required to bring about complete, long-lasting resolution of clinical signs. 相似文献

Hemolysis of serum and plasma samples is a common problem in veterinary diagnostic laboratories. We measured the effects of hemolysis on nine plasma analytes in 10 clinically normal common green iguanas (Iguana iguana). Blood samples with moderate and marked hemolysis were produced from each iguana by freezing, centrifuging, and decanting plasma from a portion of each blood sample, and combining the nonhemolyzed plasma with different amounts of hemolyzed plasma from the same individual. Moderate hemolysis significantly increased plasma phosphorus levels. Marked hemolysis significantly increased plasma values of potassium, phosphorus, total protein, and aspartate aminotransferase. The severity of hemolysis must be considered when interpreting values for these analytes in iguana plasma. 相似文献

Tendon ossification in the crus and tarsometatarsal regions of cranes makes ultrasonography difficult everywhere except for joints, where ossification is absent. Normal ultrasonographic anatomy of the adult Florida sandhill crane (Grus canadensis pratensis) intertarsal joint is described on the basis of ultrasonography that was performed on the limbs of a cadaver, which were dissected and cross-sectioned subsequently, to correlate ultrasonographic images with anatomic structures. Intertarsal joints of five normal sandhill cranes and two cranes with known intertarsal abnormalities were then imaged bilaterally in transverse and sagittal planes. Ultrasonographic imaging can be used to evaluate the soft-tissue structures on the dorsal and plantar aspects of the intertarsal joint of cranes, and it is a useful adjunct to physical and radiographic examination for localizing injuries to this area. 相似文献

Objective-To evaluate antinociceptive effects on thermal thresholds after oral administration of tramadol hydrochloride to Hispaniolan Amazon parrots (Amazona ventralis). Animals-15 healthy adult Hispaniolan Amazon parrots. Procedures-2 crossover experiments were conducted. In the first experiment, 15 parrots received 3 treatments (tramadol at 2 doses [10 and 20 mg/kg] and a control suspension) administered orally. In the second experiment, 11 parrots received 2 treatments (tramadol hydrochloride [30 mg/kg] and a control suspension) administered orally. Baseline thermal foot withdrawal threshold was measured 1 hour before drug or control suspension administration; thermal foot withdrawal threshold was measured after administration at 0.5, 1.5, 3, and 6 hours (both experiments) and also at 9 hours (second experiment only). Results-For the first experiment, there were no overall effects of treatment, hour, period, or any interactions. For the second experiment, there was an overall effect of treatment, with a significant difference between tramadol hydrochloride and control suspension (mean change from baseline, 2.00° and -0.09°C, respectively). There also was a significant change from baseline for tramadol hydrochloride at 0.5, 1.5, and 6 hours after administration but not at 3 or 9 hours after administration. Conclusions and Clinical Relevance-Tramadol at a dose of 30 mg/kg, PO, induced thermal antinociception in Hispaniolan Amazon parrots. This dose was necessary for induction of significant and sustained analgesic effects, with duration of action up to 6 hours. Further studies with other types of noxious stimulation, dosages, and intervals are needed to fully evaluate the analgesic effects of tramadol hydrochloride in psittacines. 相似文献

Twenty-eight llamas with a mean age of 6.2 months had bilateral forelimb valgus deformities. The range of valgus deformity, as measured on a craniocaudal radiographic view, was 6 to 25 degrees, with a similar degree of deviation in each limb. Morphologic abnormalities in the distal portion of the radius and ulna were more prominent in the ulna and included metaphyseal and epiphyseal flaring, physeal ectasia, and metaphyseal sclerosis. Distal radial epiphyseal ectasia, and metaphyseal sclerosis. Distal radial epiphyseal wedging was believed to be secondary to the ulnar deformity. Radial bowing with lateral and caudal concavity and unequal cortical thickness was evident. Epiphyseal and metaphyseal flaring with physeal ectasia was noticed in the distal portion of the third and fourth metacarpal bones. Carpal bones were unaffected. 相似文献
