Articular cartilage defects are one of the features of osteoarthritis in animals and humans. Early detection of cartilage defects is a challenge in clinical veterinary practice and also in translational research studies. An accurate, diagnostic imaging method would be desirable for detecting and following up lesions in specific anatomical regions of the articular surface. The current prospective experimental study aimed to describe the accuracy of computed tomographic arthrography (CTA) for detecting cartilage defects in a common animal model used for osteoarthritis research, the ovine stifle (knee, femoropatellar/femorotibial) joint...

The goals of this retrospective clinical case series study were to describe the management of anesthesia, and to report perioperative complications in cats undergoing subcutaneous ureteral bypass (SUB) placement due to ureteral obstruction. Medical records of client-owned cats with ureteral obstruction and anesthetized for SUB placement between 2012 and 2015 in a veterinary teaching hospital were reviewed. Twenty-seven cases were identified. Duration of anesthesia and surgery (mean ± standard deviation) were 215 ± 42 min and 148 ± 36 min, respectively...

Perianesthetic hypothermia is one of the most common complications in veterinary anesthesia, especially in small patients with a large body surface area to mass ratio. During anesthesia, body heat can be lost through 4 mechanisms-radiation, convection,conduction, and evaporation-but anesthetists frequently address only one mechanism at a time. Here we sought to evaluate 3 methods of preventing perianesthetic hypothermia in callimicos (Callimico goeldii). In our experience, these smallNHP routinely become hypothermic under even brief inhalant anesthesia...

OBJECTIVE: To describe the technique and outcomes of laparoscopic adrenalectomy (LA) in cats with adrenocortical neoplasia. STUDY DESIGN: Retrospective case series. ANIMALS: Eleven client-owned cats with unilateral adrenal tumors. METHODS: Medical records of cats that underwent LA for unilateral functional adrenal tumors at 3 veterinary teaching hospitals were reviewed. Data collected included signalment, clinical signs, physical examination findings, diagnostic imaging results, preoperative laboratory tests, laparoscopic port placement and techniques, duration of anesthesia and surgery, complications, concomitant procedures, need for conversion to an open celiotomy, histopathological diagnosis, and postoperative survival...

Cynomolgus monkeys are closely related to humans phylogenetically, and this has resulted in their widespread use as a preclinical model. Hematological data with regard to these monkeys are thus important. Although reference values for blood components and sex hormones have been established for cynomolgus monkeys, those for arterial blood gases have not. The arterial blood gases quickly reflect respiratory and circulatory dynamics, and are thus useful for animal management and safe general anesthesia and surgical operations...

OBJECTIVE: To assess the reliability of using video recordings to evaluate anesthesia recovery in dogs. STUDY DESIGN: Prospective study. ANIMALS: A total of 30 dogs undergoing surgery. METHODS: Recovery monitoring and video recording lasted from extubation until 1 hour later.

This study was conducted to determine plasma thyroxine (T4) concentrations in zoo-kept black-tailed prairie dogs ( Cynomys ludovicianus ). Thirty-one healthy prairie dogs of both sexes were studied as part of their annual clinical health evaluation, performed under general isoflurane anesthesia. Each animal underwent a complete physical examination, complete blood count, plasma biochemistry, and venous blood gas analysis. Heparinized venous blood samples were collected individually and processed for plasma T4 analysis using a veterinary biochemistry analyzer...

BACKGROUND: It remains unknown how single-shot anesthesia influences physical parameters, especially respiratory function and blood oxygen level of common marmosets (Callithrix jacchus) which came to be used for laboratory research. METHODS: We measured blood oxygen levels, both before and after oxygenation, in 13 common marmosets under two single-shot anesthesia conditions: ketamine/xylazine/atropine and alphaxalone. RESULTS AND CONCLUSIONS: We found that SpO2 values decreased to about 80% in the ketamine/xylazine/atropine protocol and fell just below 90% in the alphaxalone protocol...

BACKGROUND: Outcome of acute experimental spinal cord injury is strongly associated with tissue perfusion and oxygenation. Cardiopulmonary depression could affect outcome in dogs undergoing general anesthesia for surgical treatment of thoracolumbar intervertebral disk extrusion (IVDE). HYPOTHESIS/OBJECTIVES: To evaluate the effects of general anesthesia on functional outcome in dogs undergoing surgery to treat thoracolumbar IVDE. ANIMALS: Eighty-four client-owned dogs with acute thoracolumbar IVDE treated by decompressive hemilaminectomy...

Periodontal disease is extremely common in companion animal practice. Patients presenting for a routine oral examination and prophylaxis may be found to have extensive periodontal disease and attachment loss. Vertical bone loss is a known sequela to periodontal disease and commonly involves the distal root of the mandibular first molar. This case report outlines two dogs presenting for oral examination and prophylaxis with general anesthesia. Both patients did not have any clinical symptoms of periodontal disease other than halitosis...

OBJECTIVE: To report a case of successful surgical removal of a guide wire lost during central venous catheterization. CASE SUMMARY: A 28 kg, 4-year-old female neutered mixed breed dog presented to the primary care veterinarian with diabetic ketosis. During the process of central venous catheterization, the guide wire was accidently released and the entire length of the guide wire slipped into the jugular vein.

The combination of ketamine and an α2 -receptor agonist is often used in veterinary medicine. Four different α2 -receptor agonists, medetomidine, detomidine, xylazine and romifidine, which differ in their chemical structure and thus in selectivity for the α2 -receptor and in the sedative and analgesic potency, are typically employed during surgery of equines. Recovery following anesthesia with ketamine and an α2 -receptor agonist is dependent on the α2 -receptor agonist. This prompted us to investigate i) the inhibition characteristics for the N-demethylation of ketamine to norketamine and ii) the formation of the ketamine metabolites norketamine, 6-hydroxynorketamine (6HNK) and 5,6-dehydronorketamine (DHNK) in presence of the four α2 -receptor agonists and equine liver microsomes...

OBJECTIVE: To review current knowledge surrounding the effects, treatment, and prognosis of hypothermia in people, dogs, and cats, as well as the application of therapeutic hypothermia in clinical medicine. ETIOLOGY: Hypothermia may be a primary or secondary condition, and may be due to environmental exposure, illness, medications, anesthesia, or trauma. Hypothermia has been applied therapeutically in human medicine for a variety of conditions, including postcardiac arrest...

BACKGROUND: Surgical treatment of colic is expensive and complications may occur. Information on the prognosis and the use of the horse after surgery for colic is important for surgeons and owners. Current literature on return to athletic function after celiotomy is limited. The present study reviewed surgical cases of the Veterinary Teaching Hospital, Helsinki, Finland for 2006-2012. The aim was to follow the population of horses of different breeds for surgical findings, postsurgical complications, long-term recovery and prognosis...

The objective of this study was to model the pharmacokinetics (PKs) of robenacoxib in cats using a nonlinear mixed-effects (NLME) approach, leveraging all available information collected from cats receiving robenacoxib s.c. and/or i.v.: 47 densely sampled laboratory cats and 36 clinical cats sparsely sampled preoperatively. Data from both routes were modeled sequentially using Monolix 4.3.2. Influence of parameter correlations and available covariates (age, gender, bodyweight, and anesthesia) on population parameter estimates were evaluated by using multiple samples from the posterior distribution of the random effects...

An 8-yr-old, captive, female golden lion tamarin ( Leontopithecus rosalia ) with a 6-yr history of hyperbilirubinemia was examined for inappetence and weight loss. Physical examination and blood pressure monitoring under anesthesia revealed hypothermia and hypotension, and blood work revealed hypoglycemia, markedly elevated liver enzymes, including serum alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase, and confirmed the hyperbilirubinemia. A complete blood count suggested chronic lymphoid leukemia...
