In veterinary medical education, reduction, replacement, and refinement (the three Rs) must be considered. Three clinical skills in anesthesia were identified as challenging to students: endotracheal intubation, intravenous catheterization, and drug dose calculations. The aims of this project were to evaluate students' perception of their level of confidence in performing these three clinical skills in veterinary anesthesia, to document the extent of students' previous experience in performing these three tasks, and to describe students' emotional states during this training...

Maria Claudia Campos Mello Inglez de Souza, Ricardo José Rodriguez Ferreira, Geni Cristina Fonseca Patricio, Julia Maria Matera
Somatosensory evoked potentials (SSEPs) and motor evoked potentials (MEPs) are non-invasive neurophysiological tests that reflect the functional integrity of sensory and motor pathways. Despite their extensive use and description in human medicine, reports in veterinary medicine are scarce. SSEPs are obtained via peripheral stimulation of sensory or mixed nerves; stimulation induces spinal and cortical responses, which are recorded when sensory pathways integrity is preserved. MEPs can be obtained via transcranial electrical or magnetic stimulation; in this case, thoracic and pelvic limb muscle responses are captured if motor pathways are preserved...

The automated oscillometric method is a common method for measuring blood pressure non-invasively and is broadly and confidently used in the veterinary setting. Twenty-one pigs undergoing anesthesia for exploratory laparotomy were enrolled in a study to evaluate the performance of the Surgivet V9203 non-invasive blood pressure (NIBP) monitor. The aim was to compare measurements of arterial blood pressure obtained simultaneously using the Surgivet V9203 oscillometric system and an intra-arterial catheter-transducer system, both at the level of the metatarsus...

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 small NHP routinely become hypothermic under even brief inhalant anesthesia...

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...

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...

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...

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...

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...
