Fourteen captive Livingstone's fruit bats ( Pteropus livingstonii) were anesthetized for routine veterinary health checks, including echocardiography, using sevoflurane. In addition, three specimens suffering from cardiac disease and a pregnant specimen were anesthetized for clinical assessment. No anesthetic complications were observed in any of the specimens. Significant differences in the core body temperature were found between the esophageal and rectal measurements. A significant decrease in blood glucose was noted through the anesthesia, suspected to be related to an extended fasting period prior to the procedure...

The use of personal protective equipment by veterinary workers during radiographic imaging is inconsistent. While the self-reported use of leaded aprons and thyroid shields approaches 100% in some studies, the use of leaded gloves and eyeglasses is much lower. Previous studies describing personal protective equipment use are based on self-reporting. Objectives of this prospective, observational study were to describe use of leaded personal protective equipment during radiographic imaging by veterinary workers, and to compare observed use with self-reported use...

Local anesthesia is an effective method to control pain. Neosaxitoxin is a phycotoxin whose molecular mechanism includes a reversible inhibition of voltage-gated sodium channels at the axonal level, impeding nerve impulse propagation. The present study was designed to evaluate the clinical efficacy of Neosaxitoxin as a local long-acting pain blocker in horse bucked shins, and it was found to effectively control pain. While Neosaxitoxin and Gonyautoxin, another Paralytic Shellfish Poison (PSP) toxin, have been successfully used in humans as long-lasting pain blockers, this finding marks the first time a PSP has been shown to have an established effect in veterinary medicine...

In cases where semen collection in tom-cats is not possible, FNA of testes is the alternative to evaluate sperm production. Although this technique for the diagnosis of fertility problems has been well discussed in other mammals (men, dogs, stallions), data for domestic cats are limited. Therefore, the aim of this study was to verify the reliability of FNA using needles of small diameters (22G and 29G) in testes of domestic cats of different ages to assess the spermatogenesis status and to present description of germ cells and Sertoli cells for cytological examinations...

Use of hypothermia as a means of anesthesia for amphibians and reptiles is prohibited by agencies that establish veterinary guidelines. This has recently been called into question by members of the scientific community based on reviews of published literature. Using pond turtles (Trachemys scripta elegans), hypothermia as a method for anesthesia to precede euthanasia by decapitation was assessed. Turtles were subjected to hypothermia using a cooling followed by freezing protocol. Body temperature measurements ranged between -1 to -2°C while core body temperature was -1°C...

Anesthesia simulations have been used in pre-clinical medical training for decades to help learners gain confidence and expertise in an operating room environment without danger to a live patient. The authors describe a veterinary anesthesia simulation environment (VASE) with anesthesia scenarios developed to provide a re-creation of a veterinarian's task environment while performing anesthesia. The VASE uses advanced computer technology with simulator inputs provided from standard monitoring equipment in common use during veterinary anesthesia and a commercial canine training mannequin that allows intubation, ventilation, and venous access...

CASE SUMMARY: An approximately 3-year-old, male domestic longhair cat was presented to a mobile veterinary unit for routine neuter. Preoperative physical examination revealed an approximately 5 cm × 2 cm scab on the craniolateral portion of the left antebrachium. The cat was anesthetized for the neuter using an injectable anesthesia protocol. After castration, the wound area on the antebrachium was clipped, copiously lavaged and the wound edges were surgically debrided. Injectable antibiotics and analgesic management were instituted...

There is currently no available information regarding the veterinary management of Sunda clouded leopards (Neofelis diardi), either in captivity or in the wild. In this study, 12 Sunda clouded leopards were anesthetized between January 2008 and February 2014 for medical exams, and/or GPS-collaring. Seven wild-caught individuals were kept in captivity and 5 free-ranging animals were captured by cage traps. Two anesthesia combinations were used: medetomidine-ketamine (M-K) or tiletamine-zolazepam (T-Z). Atipamezole (0...

Assessments can cause significant distress in veterinary students and are listed as some of the greatest causes of academic stress. The purpose of this natural experiment was to determine if there is a relationship between amount of time given to complete quizzes and the students' score on the quiz. The Principles of Anesthesia course is required of all students. Quizzes are administered at the start of a class period and spaced throughout the course to cover 2-4 lectures per quiz. Once the allotted time has passed (3-6 minutes), students are notified they have 2 minutes to return the quiz to the instructor...

Involvement in canine and feline surgical neutering clinics is generally considered to be a key element of primary-care veterinary education, yet opportunities for veterinary students to develop their surgical skills with rabbit patients are uncommon. This is despite the fact that rabbits are currently estimated to be the third-most popular companion animal species and the fact that the British Small Animal Veterinary Association (BSAVA) recommends that all non-breeding rabbits be neutered soon after they attain sexual maturity...

Isoflurane gas anesthesia is often used for immobilization of prairie dogs in field studies, laboratory research, and veterinary clinical purposes. The goals of this prospective study were to evaluate the effects of sternal versus right lateral recumbency on trends of selected physiologic parameters during isoflurane anesthesia in black-tailed prairie dogs ( Cynomys ludovicianus ). Fourteen adult, zoo-housed black-tailed prairie dogs were tested during the study. Animals were anesthetized using isoflurane and randomly placed in either sternal or right lateral recumbency to evaluate changes in trends of physiologic parameters, measured selectively every 30 min throughout a 60-min anesthesia period...

Anesthesia and surgery in cetaceans have inherent risks and have rarely been utilized as viable treatment options. This report represents the first known multidisciplinary team approach to emergency laparotomy in a compromised, 22-yr-old, female Pacific white-sided dolphin ( Lagenorhynchus obliquidens ). The inciting clinical signs and ancillary diagnostics were consistent with a mechanical ileus. Although no torsion or obstruction was apparent during surgery, severe enteritis and peritonitis were noted. Postoperatively, the animal was maintained on aggressive medical management with continuous supportive care until succumbing 3 days later with clinical pathology indicative of terminal sepsis and profound inflammation...

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...

REVIEW
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...
