Teaching veterinary students using shelter animals

Veterinary teaching hospitals (VTHs) are experiencing case-load trends that have negatively affected efforts to prepare students for entry-level veterinary practice, particularly in the area of technical skills training. This article examines the clinical training available to veterinary students through a variety of collaborative shelter models. Benefits and potential problems related to initiating a collaborative shelter clinical training program are reviewed. Collaborative efforts between animal shelters and veterinary schools can provide crucial opportunities for outreach teaching initiatives, particularly for teaching medical and surgical skills.     

Features that contribute to the usefulness of low-fidelity models for surgical skills training

For practical, ethical and economic reasons, veterinary surgical education is becoming increasingly dependent on models for training. The limited availability and high cost of commercially produced surgical models has increased the need for useful, low-cost alternatives. For this reason, a number of models were developed to be used in a basic surgical skills course for veterinary students. The models were low fidelity, having limited resemblance to real animals. The aim of the present study was to describe the students' learning experience with the models and to report their perception of the usefulness of the models in applying the trained skills to live animal surgery. One hundred and forty-six veterinary fourth-year students evaluated the models on a four-point Likert scale. Of these, 26 additionally participated in individual semistructured interviews. The survey results showed that 75 per cent of the students rated the models 'useful'/'very useful'. Interviews revealed that tactile, dimensional, visual, situational and emotional features are important to students' perception of a successful translation of skills from models to live animal. In conclusion, low-fidelity models are useful educational tools in preparation for live animal surgery. However, there are specific features to take into account when developing models in order for students to perceive them as useful.     

Teaching surgery to the veterinary novice: the Ohio State University experience

Surgical training in veterinary medicine has evolved rapidly over the past several decades. Catalysts for change include pressure from concerned students and the public to reduce the use of live animals in teaching; less-than-effective preparation of students for live surgery experience; an overall reduction in faculty time and effort devoted to skills training; college budgetary reallocations mandating reductions in expensive group laboratory experiences; and more specialized case-load patterns in clinical rotations, which have reduced students' exposure to common surgical conditions. In response to these trends, methods for surgery educators to reduce, refine, and replace live animals in surgery training courses at veterinary schools have received broad attention. When these methods are used effectively in a curriculum, it is no longer necessary to sacrifice animals for adequate student training. This article describes a successful and ethical surgical training program used at the Ohio State University College of Veterinary Medicine (OSU-CVM). This program provides early exposure to skills training using surgical simulators and auto-tutorials, ensures that basic skills are mastered before students are exposed to cadaver practice, and requires application of model-based skills to cadavers, with final matriculation to intensive exposure to multiple live-animal procedures via a collaborative surgery program with a local shelter.

How does emotional intelligence fit into the paradigm of veterinary medical education?

The term 'emotional intelligence' (EI) has become very popular in the business world and has recently infiltrated veterinary medical education. The term purports to encompass those qualities and skills that are not measured by IQ tests but do play an important role in achieving success in life. Veterinary medical educators often incorporate these in a category called 'non-technical competencies' (which includes, for example, communication skills) and acknowledge that veterinarians need more training in this area in order to be successful. Although EI looks promising as a means for teaching these non-technical competencies to students and practitioners, there are some challenges to its application. To begin with, there are three competing models of EI that differ in definition and measuring instruments. Although some research has suggested that high EI is associated with success in school and in business, there are no studies directly correlating high EI with greater success in the veterinary profession. Nor have any studies confirmed that increasing a student's EI will improve eventual outcomes for that student. It is important that educators approach the implementation of new techniques and concepts for teaching non-technical competencies the same way they would approach teaching a new surgical technique or drug therapy. EI is an intriguing and promising construct and deserves dedicated research to assess its relevance to veterinary medical education. There are opportunities to investigate EI using case control studies that will either confirm or discredit the benefits of incorporating EI into the veterinary curriculum. Implementing EI training without assessment risks wasting limited resources and alienating students.     

Mainstreaming alternatives in veterinary medical education: resource development and curricular reform

Veterinary medical educators are charged with preparing students to enter practice in veterinary medicine during a four-year, intensive, professional education program. This requires giving students in laboratory training that involves dead, anesthetized, or conscious animals, so that they become proficient in the expected range of veterinary knowledge, skills, and abilities. Undeniably, experience with animals is essential to prepare students for a profession in which animals comprise the total domain. However, the consumptive use of animals for teaching students, especially in laboratories, is increasingly subject to regulatory requirements, while also being scrutinized by animal protection groups, and has become a common focus of contention among veterinary students. Not surprisingly, the use of animals in teaching has sharply declined over the past few decades, as new teaching resources and methods, involving less consumptive use of animals, have been incorporated. This change in veterinary medical education has occurred on such a wide scale, in almost all veterinary schools and colleges, that the educational approach can serve as a model for further developments within the veterinary educational community and, indeed, for animal-related material in secondary schools and undergraduate higher education. This article highlights examples of the leadership provided by veterinary educators in developing alternative teaching resources and methods, while maintaining the high level of proficiency expected from traditional educational approaches.

Lumbo-sacral epidural anaesthesia as a complement to dissociative anaesthesia during scrotal herniorrhaphy of livestock pigs in the field

Background

In Sweden, scrotal or inguinal herniorrhaphy of livestock pigs in the field has traditionally been an important part of the surgical skills training of veterinary students. Few substances meet the legal requirements for field anaesthesia of production animals in the European Union but a protocol based on azaperone-detomidine-butorphanol-ketamine does. Unfortunately the anaesthesia is characterised by unpredictable duration and depth and of abrupt awakenings which is not acceptable from an animal welfare perspective and impedes surgical training. Lumbo-sacral epidural analgesia is proven to provide sufficient analgesia to allow abdominal surgery, but there are few reports on the field use of this loco-regional technique. The study aim was to evaluate whether lumbo-sacral anaesthesia can be safely and successfully used in the field by a veterinary student and whether the combination of dissociative and lumbo-sacral epidural anaesthesia improves analgesia and anaesthesia to guarantee animal welfare during herniorrhaphy in livestock pigs, enabling surgical skills training.

Results

Pigs in the control-group (placebo) responded significantly stronger to surgery, with five out of 11 requiring additional doses of detomidine and ketamine. There were no significant differences between groups in respiratory rate, heart rate, blood pressure, SpO₂ or blood gases. SpO₂ levels <94 % were recorded in several pigs in both groups. No post-injection complications were reported at follow-up.

Conclusions

The results from this study showed that lumbo-sacral epidural anaesthesia with lidocaine could successfully be administered during dissociative anaesthesia of livestock pigs by a veterinary student and without reported post-injection complications. It improved analgesia and anaesthesia during herniorrhaphy of sufficient duration to enable surgical skills training. The risks and consequences of hypoxaemia and hypoventilation should be considered.     

Evaluation of a Hemostasis Model for Teaching Basic Surgical Skills

The need for alternative methods of teaching veterinary medicine and surgery has increased in recent years because of increasing costs and changing public opinion. For these reasons a hemostasis model was developed that mimics the arteries and veins of the peripheral vascular system, and can be used to teach the basic skills involved in blood vessel ligation and division. This study evaluated the effectiveness of the fluid hemostasis model compared with using live animals for teaching these skills. Forty sophomore veterinary students participated in the study. Two groups of 20 students each received identical instruction in the basic techniques required for vessel ligation and division. The students then completed various exercises using inanimate models to objectively evaluate their psychomotor skills. Both groups then practiced the techniques for equal time periods; one group used the hemostasis model and the other performed a splenectomy on live dogs. After the practice session, the students were videotaped (for later evaluation), as they performed vessel ligations and divisions. The students then repeated the exercises using the inanimate models for evaluation of skills improvement. Questionnaire responses before and after the project were obtained to determine the students' views on the need for inanimate models for teaching purposes. Results of this study indicate that the hemostasis model was as effective as live animals for teaching the basic skills involved in blood vessel ligation. The students' opinions regarding the use of properly designed inanimate models for teaching these skills were dramatically changed.     

Evaluation of a hemostasis model for teaching ovariohysterectomy in veterinary surgery

OBJECTIVE: To evaluate the efficacy of a reusable plastic model mimicking the anatomy and hemodynamics of the canine female genital tract for teaching basic surgical skills and ovariohysterectomy. SAMPLE POPULATION: 40 veterinary students of the class of 1998. STUDY DESIGN: Prospective study. METHODS: Students'confidence level and experience in private practice was evaluated via questionnaire before training. Students in 2 groups performed an ovariohysterectomy on cadavers (group C, n = 20) or on the model (Group M, n = 20) for 2 hours. Students' psychomotor and basic surgical skills were objectively assessed by the following tests: ligation of a foam cylinder, passing a needle through the eyelets of an electronic suture board, and ligating latex tubing. Results were compared before and after training and within and between groups. The ability of students to perform an ovariohysterectomy in a live dog after training was compared between groups with a scoring system. RESULTS: Students in both groups had similar surgical experience and basic skills before training. The results of the psychomotor and basic surgical skills tests were better in group M after training than group C. The improvement of each student in performing these tasks also increased when students were trained with the model. Scores assigned to students performing an ovariohysterectomy in a live dog were higher in group M (31.45 +/- 1.15) than in group C (20.7 +/- 1.42). CONCLUSION: The model was more effective than cadavers in teaching basic surgical skills and ovariohysterectomy in dogs.     

Evaluation of Video Tape and a Simulator for Instruction of Basic Surgical Skills

Twenty first-year veterinary students with no prior participatory experience in surgery were randomly paired and assigned into two study groups. Ten students (group V) viewed a hemostatic technique video tape until they thought they could competently perform and assist in performing a hand-tied ligature on a blood vessel in a live animal. Ten students (group VS) wer also given a simulator for technique practice. Paired students were video recorded and blindly evaluated on their ability to perform and assist proper ligation of a bleeding vessel. Inexpensive hemostasis models were very helpful for teaching students essential surgeon and assistant skills involved in hand-tied ligature placement. Students who practiced with simulators performed significantly better as surgeon and assistant, and in total psychomotor skill evaluation, then students watching the video only. Students using simulators performed ligation with significantly more accuracy and tended to be more expeditious at this task. Further training is needed for students to acquire skills necessary for efficient bleeding vessel exposure and isolation.     

Effective bibliographic searching for animal alternatives in veterinary medical education: the UC Davis web site

To prepare students in just four years to enter veterinary practice, veterinary medical educators offer an array of laboratory and clinical experiences coordinated with didactic instruction. Recent curricular changes have reduced the numbers of animals involved in painful or terminal procedures. For each use of animals, veterinary educators are required by the USDA's policies 11 and 12 to complete animal-use protocols that include questions on alternatives to procedures causing more than momentary pain or distress. Veterinary medical educators seeking improved teaching resources and methods or completing animal-use protocols may find it frustrating to locate the relevant information, which is dispersed across many databases. This paper addresses a gap facing veterinary educators by presenting user-friendly searching tools that are targeted toward (a) locating teaching resources and (b) conducting effective bibliographic searches on standard teaching laboratory procedures, as required for animal-use protocols. These tools simplify searching by providing streamlined access to the resources being sought. Facilitating efficient and effective searching by users can improve teaching and simplify compliance with USDA requirements.     

Building on existing models from human medical education to develop a communication curriculum in veterinary medicine

Communication is a core clinical skill of veterinary medicine and one that needs to be taught and learned to the same degree as other clinical skills. To provide this education and essential expertise, veterinary schools in many countries, especially including North America, the United Kingdom, and Australia, have begun to develop programs and communication curricula. Human medical education, however, has 30 years' experience in developing communication curricula, and is thus an excellent resource upon which veterinary educators can build and shape their own communication programs. This article describes a skills-based communication course that has been successfully implemented for veterinary medical education at Ontario Veterinary College (OVC) and was based on the University of Calgary Faculty of Medicine's well-established program. The Calgary-Cambridge Guides and supporting textbooks provide the scaffolding for teaching, learning, and evaluation in both programs. Resources such as space and materials to support the OVC program were also patterned after Calgary's program. Communication skills, and the methods for teaching and learning them, are equally applicable for the needs of both human medicine and veterinary medicine. The research evidence from human medicine is also very applicable for veterinary medicine and provides it the leverage it needs to move forward. With this extensive base available, veterinary medicine is in a position to move communication skills training forward rapidly.     

The perioperative management of small animals with previously implanted pacemakers undergoing anaesthesia

ObjectiveThere is little information in the veterinary literature about the perioperative management of small animal patients with previously implanted pacemakers undergoing elective or emergency non-cardiac procedures. The purpose of this article is to review the current literature with regard to human patients, with previously implanted pacemakers, undergoing general anaesthesia. Using this and the current information on pacemakers and anaesthesia in dogs and cats, we provide recommendations for small animal patients in this situation.Databases usedGoogle Scholar, PubMed and CAB Abstracts using and interlinking and narrowing the search terms: “dog”, “cat”, “small animals”, “anaesthesia”, “pacemaker”, “perioperative”, “transvenous pacing”, “temporary pacing”. Scientific reports and human and small animal studies from the reference lists of the retrieved papers were reviewed. In addition, related human and veterinary cardiology and anaesthesia textbooks were also included to create a narrative review of the subject.ConclusionsThe best perioperative care for these animals comes from a multidisciplinary approach involving the anaesthetist, cardiologist, surgeon and intensive care unit team. When such an approach is not feasible, the anaesthetist should be familiar with pacemaker technology and how to avoid perioperative complications such as electromagnetic interference, lead damage and reprogramming of the device. The preanaesthetic assessment should be thorough. Information regarding the indication for pacemaker placement, complications during the procedure, location, type and programming of the pacemaker should be readily available. The anaesthetic management of these veterinary patients aims to preserve cardiovascular function while avoiding hypotension, and backup pacing should be available during the perioperative period. Further prospective studies are needed to describe the best perioperative care in small animals with a previously implanted pacemaker.     

Survey of complications and antimicrobial use in equine patients at veterinary teaching hospitals that underwent surgery because of colic

OBJECTIVE: To determine current practices regarding use of antimicrobials in equine patients undergoing surgery because of colic at veterinary teaching hospitals. DESIGN: Survey. SAMPLE POPULATION: Diplomates of the American College of Veterinary Surgeons performing equine surgery at veterinary teaching hospitals in the United States. PROCEDURE: A Web-based questionnaire was developed, and 85 surgeons were asked to participate. The first part of the survey requested demographic information and information about total number of colic surgeries performed at the hospital, number of colic surgeries performed by the respondent, and whether the hospital had written guidelines for antimicrobial drug use. The second part pertained to nosocomial infections. The third part provided several case scenarios and asked respondents whether they would use antimicrobial drugs in these instances. RESULTS: Thirty-four (40%) surgeons responded to the questionnaire. Respondents indicated that most equine patients undergoing surgery because of colic at veterinary teaching hospitals in the United States received antimicrobial drugs. Drugs that were used were similar for the various hospitals that were represented, and for the most part, the drugs that were used were fairly uniform irrespective of the type of colic, whereas the duration of treatment varied with the type of colic and the surgical findings. The combination of potassium penicillin and gentamicin was the most commonly used treatment. CONCLUSIONS AND CLINICAL RELEVANCE: Results of this study document the implementation of recommendations by several authors in veterinary texts that antimicrobial drugs be administered perioperatively in equine patients with colic that are undergoing surgery. However, the need for long-term antimicrobial drug treatment in equine patients with colic is unknown.

The use of haemostatic gelatin sponges in veterinary surgery

Objectives : To describe the use of absorbable gelatin sponges as haemostatic implants in clinical veterinary surgical cases and to document any related postoperative complications. Methods : Practice databases were searched for the product names “Gelfoam” and “Spongostan”. Patient records were retrieved and data regarding patient signalment, surgical procedure, National Resource Council (NRC) wound classification, source of haemorrhage, pre‐ and postoperative body temperature, postoperative complications, time to discharge and details of any postoperative imaging were recorded and reviewed. Follow‐up information was obtained by repeat clinical examination or telephone interview with either the owner or referring veterinary surgeon. Cases with incomplete surgical records or those which were not recovered from anaesthesia were excluded from the analysis. Results : Fifty cases (44 dogs and 6 cats) satisfied the inclusion criteria. Satisfactory haemostasis was achieved in 49 cases with one case requiring reoperation during which a second gelatin sponge was used. There were no detected hypersensitivity responses or confirmed postoperative complications relating to the use of gelatin sponges during the follow‐up period (median 13 months). Clinical Significance : This is the first review of the use of gelatin sponges in clinical veterinary surgery and suggests that gelatin sponges are safe to use in cats and dogs.

Guidelines for resident training in veterinary clinical pathology. III: cytopathology and surgical pathology

The Education Committee of the American Society for Veterinary Clinical Pathology has identified a need for improved structure and guidance of training residents in clinical pathology. This article is the third in a series of articles that address this need. The goals of this article are to describe learning objectives and competencies in knowledge, abilities, and skills in cytopathology and surgical pathology (CSP); provide options and ideas for training activities; and identify resources in veterinary CSP for faculty, training program coordinators, and residents. Guidelines were developed in consultation with Education Committee members and peer experts and with evaluation of the literature. The primary objectives of training in CSP are: (1) to develop a thorough, extensive, and relevant knowledge base of biomedical and clinical sciences applicable to the practice of CSP in domestic animals, laboratory animals, and other nondomestic animal species; (2) to be able to reason, think critically, investigate, use scientific evidence, and communicate effectively when making diagnoses and consulting and to improve and advance the practice of pathology; and (3) to acquire selected technical skills used in CSP and pathology laboratory management. These guidelines define expected competencies that will help ensure proficiency, leadership, and the advancement of knowledge in veterinary CSP and will provide a useful framework for didactic and clinical activities in resident‐training programs.
