RESUMO

Curriculum leaders (individuals with responsibility for an institution's veterinary curriculum) play a vital role in driving local curriculum priorities, development, and accreditation. This study aimed to describe the career paths of curriculum leaders, and identify what motivates them, the barriers they face, and the knowledge, skills, and attributes they perceive as essential for the role. Self-determination theory was used to identify tensions experienced within the role. An international online survey targeted at those identifying as curriculum leaders was completed by 45 participants. 91% of participants held a doctoral level qualification and/or clinical Boards; 82% had additional training in leadership; 38% had additional formal training in education. Motivators included a desire to make a difference, personal satisfaction with teaching and working with students, and social influences. Participants experienced barriers relating to self-development and achievement of their curriculum goals; participants described essential knowledge (of the profession, educational theory, and wider higher education context) and skills (leading teams, change management, and communication). Attributes considered important related both to self (open-minded, patient, resilient, able to see the big picture as well as detail) and relationships with others (approachable, listener, respectful and respected, supportive, credible). Tensions arose in participants' need for autonomy (experiencing barriers to achieving their goals), in their social relatedness (achieving curriculum goals while working with colleagues with conflicting priorities), and in perceptions of necessary competence (a need, but lack of opportunity, for advanced training in educational theory). The findings may help institutions more effectively support and train current and future curriculum leaders.

RESUMO

BACKGROUND: Whilst it is recognised that a capacity to manage uncertainty is an essential aspect of working as a healthcare professional, there is little clear guidance on how to facilitate student learning in this domain. A lack of faculty development opportunities also suggests that health professions' educators may feel ill-equipped to assist students in developing effective approaches to uncertainty. The purpose of this study was to explore a faculty development intervention designed to help educators unpack students' experiences of uncertainty, and identify attributes which may help students to manage uncertain situations. METHODS: This qualitative study was informed by a constructivist methodological approach, where participants were encouraged to share meaning around the nature of uncertainty in health professions' education. Two 90-min faculty development sessions were held. These sessions invited participants to apply Han et al.'s taxonomy of uncertainty to role-played scenarios of student uncertainty within a focus group setting. Focus group data were collected, and examined using a two-stage, hybrid approach of deductive and inductive thematic analysis. RESULTS: Han et al.'s taxonomy helped participants to identify multiple sources and issues of uncertainty in the role played scenarios, thus unveiling the extent of uncertainties encountered by health professions' learners. Data analysis revealed four themes overall: "Sources of uncertainty", "Issues of uncertainty", "Uncertainty attributes", and "Learning environment." Participants also contributed to a list of attributes which they considered helpful to undergraduate health professions' students in managing uncertain situations. These included an awareness of the nature of uncertainty within healthcare practice, an ability to recognise uncertainty, and adopting attitudes of adaptability, positivity, and resilience. CONCLUSIONS: This study highlights the successful use of Han et al.'s taxonomy of uncertainty within a faculty development setting. Our findings suggest that the taxonomy is a practical and versatile tool that health professions' educators can use in shared reflections and conversations around uncertainty with students or colleagues.

RESUMO

Most work on the professional identity of veterinary and medical professionals has been conceptualized in the USA and Europe. It reports professional identity formation to be highly individualized, triggered by experiences of identity distress, and identity negotiation strategies to be generally focused around personal reflection. However, within Asia, important sociocultural differences exist that might influence professional identity and its development. Societal values may take precedence over individual ones, and some cultures consider the veterinary profession as stigmatized. With this background, we seek to understand professional identity and its construction in Pakistani veterinary students. We selected five students through purposive sampling and invited them for narrative interviews. Social identity theory and Maslow's theory of hierarchy of needs predominantly contributed to the theoretical framework, which together with principles of social phenomenology and narrative analysis informed qualitative analysis of the transcribed interviews using an in-depth approach. We found that students' professional identity was predominantly socially constructed, though their sense of their identity was not very well developed. Role models, social stigma, professional socialization in clinical settings, gender, and to some extent, cultural interpretations of religious messages seemed to mediate professional identity development. Students responded differently to their understanding of professional stigma, making sense of stigma through strategies such as denial or internalization. Since Pakistani veterinary students experience social and personal values differently compared to those from predominantly individualistic cultures, identity formation through reflecting on personal values may be less effective than strategies that emphasize social learning and beliefs.

RESUMO

Despite a lack of diversity, studies on the experience of ethnically diverse (ED) students have not focused on veterinary education. This study used focus groups to explore the experience of ED veterinary students, their challenges, and their sources of support in this setting. Focus groups were held using two formats: a traditional, in-person approach, and online, via a social media group. Recruitment was by invitation and focus group allocation according to participant preference. Conversations were transcribed or downloaded, anonymized, and analyzed using a two-part narrative analysis, the aim of which was to understand the experiences of ED veterinary students at an in-depth level. Students experienced identity conflicts at multiple levels (self, others, profession), which appeared to relate to their ethnicity. Conflict between self and others resulted in a feeling of otherness arising from a White student majority, both within the university and on external placements, and professional identity conflicts arose between students' personal cultural values and their values as a veterinarian. Internal conflicts arose when students felt a wish to integrate but also perceived a need to segregate with similar others to obtain support and a sense of belonging to a group. These challenges have potential implications for mental well-being and career opportunities. For veterinary medicine to adapt to changing client demographics in an increasingly globalized world, a deeper understanding of the ED student experience may offer advantages in areas such as recruitment and profession retention, which will eventually support greater diversity within the professional population.

RESUMO

Critical reflection-the exploration and questioning of one's experience, beliefs, assumptions, and actions-supports resilience, empathy, the management of uncertainty, and professional identity formation. Yet for many students and educators, the techniques to engage in critical reflection are elusive. Creative methods that foster engagement with emotional and uncertain aspects of experience reportedly help some students to reflect at a more critical level than when they use reflective writing, and this study explores more deeply the experiences of such students, who used creative methods to critically reflect on challenging or troubling past events. A narrative methodology was utilized, in which researchers collaboratively co-constructed an understanding of students' experiences of reflection to identify the activities and steps they used. Creative methods did not inherently lead to critical reflection, but when this was achieved, the creative approaches seemed to facilitate a staging of reflection, which incorporated five sequential stages: preplanning creative depiction, experimenting with different ideas, deliberately completing the reflective piece, reflecting on creative work, and reflecting again on learning and development. This cyclic, repeated revisit to experience, as students engaged in each stage of their work, appeared to facilitate both a deep connection with the emotional elements of experience and a more distanced analysis. This ultimately led to a deepening of understanding of events, including the construction of students' own beliefs and empathy with others' views.

RESUMO

Professional identity and professionalism education are increasingly important to veterinary education, but many of the concepts remain intangible to veterinary students, and engagement is a persistent challenge. While whole-curriculum integration is recommended for a successful professional studies program, this is complicated by clinical faculty's discomfort with the content. Where professional studies education is centered around professional identity formation, a key element of this is the multi-perspective nature of veterinary work, with the veterinarian negotiating the needs of multiple stakeholders in animal care. Constructing teaching around a framework of professional reasoning, which incorporates the negotiation of different stakeholder needs, ethical decision making, communication, teamwork, and outcome monitoring, offers the potential to make professional identity a concept more visible to students in veterinary work, and guides students in the contextualization of taught material. A framework is presented for veterinary professional reasoning that signposts wider curriculum content and helps illustrate where material such as veterinary business studies, animal welfare, the human-animal bond, and professional responsibility, as well as attributes such as empathy and compassion, all integrate in the decisions and actions of the veterinary professional. The aims of this framework are to support students' engagement in professional studies teaching and help them use workplace learning experiences to construct an appropriate professional identity for competence and resilience in the clinic. For faculty involved in curriculum design and clinical teaching, the framework provides a tool to support the integration of professional identity concepts across the extended curriculum.

RESUMO

The nature of professionalism teaching is a current issue in veterinary education, with an individual's identity as a professional having implications for one's values and behaviors, as well as for his or her career satisfaction and psychological well-being. An appropriately formed professional identity imparts competence in making complex decisions-those that involve multiple perspectives and are complicated by contextual challenges. It enables an individual to act in a way that aligns with his or her professional values and priorities, and imparts resilience to situations in which one's actions are dissonant to these personal beliefs. There are challenges in professionalism teaching that relate to student engagement and faculty confidence in this area. However, these cannot be addressed without first defining the veterinary professional identity-in effect, the aim of professionalism teaching. In this article, existing identity models from the wider literature have been analyzed through a veterinary lens. This analysis was then used to construct a model of veterinary professional identity that incorporates the self (personal morals and values), social development (learning from the workplace environment), and professional behaviors. Individuals who form what we have termed self-environment-behavior connections are proposed to be able to use workplace learning opportunities to inform their identity development, such that environmental complexity does not obstruct the link between values and behaviors. Those who fail to connect with the environment in this way may perceive that environmental influences (e.g., the client, financial limitations) are obstructive to enacting their desired identity, and they may struggle with decision making in complex scenarios.

RESUMO

Improving Student Engagement in Veterinary Business StudiesIn a densely packed veterinary curriculum, students may find it particularly challenging to engage in the less overtly clinical subjects, yet pressure from industry and an increasingly competitive employment market necessitate improved veterinary student education in business and management skills. We describe a curriculum intervention (formative reflective assignment) that optimizes workplace learning opportunities and aims to provide better student scaffolding for their in-context business learning. Students were asked to analyze a business practice they experienced during a period of extra-mural studies (external work placement). Following return to the college, they were then instructed to discuss their findings in their study group, and produce a group reflection on their learning. To better understand student engagement in this area, we analyzed individual and group components of the assignment. Thematic analysis revealed evidence of various depths of student engagement, and provided indications of the behaviors they used when engaging at different levels. Interactive and social practices (discussing business strategies with veterinary employees and student peers) appeared to facilitate student engagement, assist the perception of relevance of these skills, and encourage integration with other curriculum elements such as communication skills and clinical problem solving.

RESUMO

Professional studies teaching in medical and veterinary education is undergoing a period of change. Traditional approaches, aiming to teach students professional values and behaviors, are being enhanced by curricula designed to support students' professional identity formation. This development offers the potential for improving student engagement and graduates' mental well-being. The veterinary professional identity associated with emotional resilience and success in practice incorporates complexity in professional decision making and the importance of context on behaviors and actions. The veterinarian must make decisions that balance the sometimes conflicting needs of patient, clients, veterinarian, and practice; their subsequent actions are influenced by environmental challenges such as financial limitations, or stress and fatigue caused by a heavy workload. This article aims to describe how curricula can be designed to support the development of such an identity in students. We will review relevant literature from medical education and the veterinary profession to describe current best practices for supporting professional identity formation, and then present the application of these principles using the curriculum at the Royal Veterinary College (RVC) as a case study. Design of a "best practice" curriculum includes sequential development of complex thinking rather than notions of a single best solution to a problem. It requires managing a hidden curriculum that tends to reinforce a professional identity conceived solely on clinical diagnosis and treatment. It includes exposure to veterinary professionals with different sets of professional priorities, and those who work in different environments. It also includes the contextualization of taught content through reflection on workplace-learning opportunities.

RESUMO

Student retention and attainment has recently been identified as a key area for development in veterinary medical education enquiry. Woodfield's research on retention and attainment across the UK disciplines has yielded some unique information about the challenges and issues of students who study veterinary medicine and related subjects. The present literature review aims to expand on Woodfield's findings and explain important issues about retention and attainment across veterinary medicine. Overall, the subject of retention and attainment in undergraduate veterinary medical education needs a great deal more empirical attention, such as data on the retention and attainment of mature and widening access students, and the effects of students being placed at remote locations during their studies. Our findings also cover some unsurprising issues: the dominance of women in a profession that is principally lead by men, the underrepresentation of black and minority ethnic (BME) students in veterinary medicine, and the effects of content overload in the veterinary medical curriculum. Based on data gathered by Woodfield and our investigation of the scholarly and gray literatures, we offer an overview of gaps in current knowledge and recommendations for further research.

RESUMO

Although widely accepted as an important graduate competence, professionalism is a challenging outcome to define and assess. Clinical rotations provide an excellent opportunity to develop student professionalism through the use of experiential learning and effective feedback, but without appropriate theoretical frameworks, clinical teachers may find it difficult to identify appropriate learning outcomes. The adage "I know it when I see it" is unhelpful in providing feedback and guidance for student improvement, and criteria that are more specifically defined would help students direct their own development. This study sought first to identify how clinical faculty in one institution currently assess professionalism, using retrospective analysis of material obtained in undergraduate teaching and faculty development sessions. Subsequently, a faculty workshop was held in which a round-table type discussion sought to develop these ideas and identify how professionalism assessment could be improved. The output of this session was a theoretical framework for teaching and assessing professionalism, providing example assessment criteria and ideas for clinical teaching. This includes categories such as client and colleague interaction, respect and trust, recognition of limitations, and understanding of different professional identities. Each category includes detailed descriptions of the knowledge, skills, and behaviors expected of students in these areas. The criteria were determined by engaging faculty in the development of the framework, and therefore they should represent a focused development of criteria already used to assess professionalism, and not a novel and unfamiliar set of assessment guidelines. The faculty-led nature of this framework is expected to facilitate implementation in clinical teaching.

RESUMO

For a constructively aligned curriculum in veterinary professionalism, there is a need for well-designed higher order learning outcomes to support students' professional identity formation. A lack of uniformly accepted definitions of veterinary professionalism necessitates the defining and refining of current concepts of professionalism to inform teaching and assessment. A potential method for achieving such learning outcomes is to generate these from simulated professionalism teaching scenarios. A workshop was designed in which veterinary educators used role play to resolve a professional dilemma. Following discussion of the appropriate management approach, participants were asked to reflect on the learning outcomes that were required to resolve the scenario and that students would achieve by going through the same classroom-based process. Workshop participants identified several professionalism learning outcomes that are not currently defined in the literature: realizing that there is not a single correct answer to a professional dilemma, making a decision despite this uncertainty, communicating differences of opinion, and understanding the effect of differences in professional identity. Although the process described runs counter to traditional curricular design, it may offer a valuable contribution to the discourse surrounding professionalism learning outcomes. Furthermore, it has generated higher level learning outcomes than have been obtained through other methods.

RESUMO

HISTORY: A four year old male neutered Domestic Short Hair cat presented for general anaesthesia for hind limb orthopaedic surgery. The cat had been anaesthetized four days previously with propofol and isoflurane and made an uneventful recovery. PHYSICAL EXAMINATION AND MANAGEMENT: On pre-anaesthetic examination the cat had a temperature of 38.9 °C and was otherwise healthy. After a premedication of acepromazine and pethidine, anaesthesia was induced with thiopental and maintained with isoflurane in oxygen 50% and nitrous oxide 50%. Increases in heart rate, respiratory rate, end tidal carbon dioxide tension and temperature were observed, occurring sequentially, from 110 to 175 minutes after anaesthetic induction. Despite ceasing all warming measures and attempting to cool the patient, body temperature continued to rapidly rise, reaching 42.5 °C and limb rigidity was observed. Isoflurane administration was stopped and esmolol was administered. Cardiac arrest occurred. Cardio-pulmonary cerebral resuscitation was commenced and a lateral thoracotomy was performed to allow cardiac compressions and internal defibrillation. Atropine, adrenaline, glucose and dopamine were administered and cold saline was instilled into the thoracic cavity. FOLLOW-UP: Resuscitation was unsuccessful and the cat died. CONCLUSIONS: A presumptive diagnosis of malignant hyperthermia was made. Malignant hyperthermia should be considered, even if prior exposure to volatile inhalational anaesthesia was uneventful, and prompt and aggressive therapy instituted.

RESUMO

OBJECTIVE: To evaluate the risk of passive regurgitation during anaesthesia, and to identify major factors associated with this in dogs attending the Queen Mother Hospital for Animals (QMHA), the Royal Veterinary College. STUDY DESIGN: A case-control study nested within the cohort of dogs undergoing anaesthesia with inhalation agents. ANIMAL POPULATION: All dogs undergoing general anaesthesia at the referral hospital between October 2006 and September 2008 (4271 cases). METHODS: All dogs anaesthetized at the QMHA during the study period were included. Regurgitating cases were defined as dogs for which reflux material was observed at the external nares or in the mouth, either during anaesthesia or before return to normal consciousness immediately after general anaesthesia. The risk of regurgitation was estimated and risk factors for regurgitation were evaluated with multivariable logistic regression (p < 0.05). RESULTS: The overall risk of regurgitation was 0.96% (41 cases out of 4271 anaesthetics, 95% confidence interval [95% CI] 0.67-1.25%). Exclusion of animals where pre-existing disease was considered a contributing factor to regurgitation (n = 14) resulted in a risk of passive regurgitation of 0.63% (27 cases of 4257 anaesthetics, 95% CI 0.40-0.87%). In the multivariable logistic regression model, procedure and patient weight were significantly associated with regurgitation. Dogs undergoing orthopaedic surgery were 26.7 times more likely to regurgitate compared to dogs undergoing only diagnostic procedures. Dogs weighing more than 40 kg were approximately five times more likely to regurgitate than those weighing <20 kg. CONCLUSIONS AND CLINICAL RELEVANCE: This study highlights the rare but important occurrence of perioperative regurgitation and identifies that dogs undergoing orthopaedic procedures, and those weighing more than 40 kg, are particularly at risk. Further work is required to evaluate the reasons for these observations.

RESUMO

BACKGROUND: This research seeks to understand how the transition to a new generation of younger, more diverse farmers affects disease prevention efforts on UK farms. METHODS: We apply multivariate regression analysis to analyse survey responses from 112 Welsh cattle farm operators. RESULTS: Our results indicate that young farm operators (less than 40 years of age) receive less frequent visits from veterinarians. Further, farm operators who identify as female are less likely to screen and vaccinate against a range of diseases. Finally, both young farmers and female farm operators are less likely to achieve disease-free certification for various economically meaningful livestock diseases. CONCLUSION: One possible explanation for these outcomes is that female farm operators and young farmers may feel excluded from long-standing social networks in the farm animal health sector.

RESUMO

Relatively little is known about regulatory T (Treg) cells and their functional responses in dogs. We have used the cross-reactive anti-mouse/rat Foxp3 antibody clone FJK-16s to identify a population of canine CD4(+) FOXP3(high) T cells in both the peripheral blood (PB) and popliteal lymph node (LN). FOXP3(+) cells in both PB and LN yielded positive staining with the newly developed anti-murine/human Helios antibody clone 22F6, consistent with the notion that they were naturally occurring Treg cells. Stimulation of mononuclear cells of LN origin with concanavalin A (Con A) in vitro yielded increased proportions and median fluorescence intensity of FOXP3 expression by both CD4(+) and CD8(+) T cells. Removal of the Con A and continued culture disclosed a CD4(+) FOXP3(high) population, distinct from the CD4(+) FOXP3(intermediate) T cells; very few CD8(+) FOXP3(high) T cells were observed, though CD8(+) FOXP3(intermediate) cells were present in equal abundance to CD4(+) FOXP3(intermediate) cells. The CD4(+) FOXP3(high) T cells were thought to represent activated Treg cells, in contrast to the FOXP3(intermediate) cells, which were thought to be a more heterogeneous population comprising predominantly activated conventional T cells. Co-staining with interferon-γ (IFN-γ) supported this notion, because the FOXP3(high) T cells were almost exclusively IFN-γ(-) , whereas the FOXP3(intermediate) cells expressed a more heterogeneous IFN-γ phenotype. Following activation of mononuclear cells with Con A and interleukin-2, the 5% of CD4(+) T cells showing the highest CD25 expression (CD4(+) CD25(high) ) were enriched in cells expressing FOXP3. These cells were anergic in vitro, in contrast to the 20% of CD4(+) T cells with the lowest CD25 expression (CD4(+) CD25(-) ), which proliferated readily. The CD4(+) CD25(high) FOXP3(high) T cells were able to suppress the proliferation of responder CD4(+) T cells in vitro, in contrast to the CD4(+) CD25(-) cells, which showed no regulatory properties.

RESUMO

OBJECTIVE: To evaluate the clinical efficacy and cardiorespiratory effects of alfaxalone as an anaesthetic induction agent in dogs with moderate to severe systemic disease. STUDY DESIGN: Randomized prospective clinical study. ANIMALS: Forty dogs of physical status ASA III-V referred for various surgical procedures. METHODS: Dogs were pre-medicated with intramuscular methadone (0.2 mg kg(-1) ) and allocated randomly to one of two treatment groups for induction of anaesthesia: alfaxalone (ALF) 1-2 mg kg(-1) administered intravenously (IV) over 60 seconds or fentanyl 5 µg kg(-1) with diazepam 0.2 mg kg(-1) ± propofol 1-2 mg kg(-1) (FDP) IV to allow endotracheal intubation. Anaesthesia was maintained with isoflurane in oxygen and fentanyl infusion following both treatments. All dogs were mechanically ventilated to maintain normocapnia. Systolic blood pressure (SAP) was measured by Doppler ultrasound before and immediately after anaesthetic induction, but before isoflurane administration. Parameters recorded every 5 minutes throughout subsequent anaesthesia were heart and respiratory rates, end-tidal partial pressure of carbon dioxide and isoflurane, oxygen saturation of haemoglobin and invasive systolic, diastolic and mean arterial blood pressure. Quality of anaesthetic induction and recovery were recorded. Continuous variables were assessed for normality and analyzed with the Mann Whitney U test. Repeated measures were log transformed and analyzed with repeated measures anova (p<0.05). RESULTS: Treatment groups were similar for continuous and categorical data. Anaesthetic induction quality was good following both treatments. Pre-induction and post-induction systolic blood pressure did not differ between treatments and there was no significant change after induction. The parameters measured throughout the subsequent anaesthetic procedures did not differ between treatments. Quality of recovery was very, quite or moderately smooth. CONCLUSIONS AND CLINICAL RELEVANCE: Induction of anaesthesia with alfaxalone resulted in similar cardiorespiratory effects when compared to the fentanyl-diazepam-propofol combination and is a clinically acceptable induction agent in sick dogs.

RESUMO

OBJECTIVE: To compare post-operative motor function in dogs that received epidural morphine and low dose bupivacaine versus epidural morphine alone following splenectomy. STUDY DESIGN: Prospective, randomized study. ANIMALS: 16 client owned dogs undergoing routine splenectomy. METHODS: Following splenectomy dogs were randomly allocated into one of two groups. The morphine group (MOR) was administered epidural morphine (0.1 mg kg(-1)); the morphine-bupivacaine group (MORB) received epidural morphine (0.1 mg kg(-1)) and low dose bupivacaine [0.25 mg kg(-1), (0.167%)]. The adjusted final volume was 0.15 mL kg(-1) in both groups. Motor function and pain assessment were performed at pre-determined times using a simple numerical motor score and the University of Melbourne Pain Scale (UMPS) respectively. An arterial blood gas was performed 2 hours following epidural administration to check for respiratory compromise. If patients scored >7 on the UMPS or were deemed painful by the observer they were administered hydromorphone intravenously and dose and time of rescue analgesia were recorded. RESULTS: There were no statistically significant differences in motor scores, pain scores, amount of rescue analgesia administered or PaCO2 between treatment groups. No dogs demonstrated respiratory depression or profound motor dysfunction at any time point during the study. 9/16 (56%) dogs did not require rescue analgesia during the first 18 hours following splenectomy. CONCLUSIONS AND CLINICAL RELEVANCE: The combination of low dose bupivacaine (0.25 mg kg(-1)) and morphine (0.1 mg kg(-1)) when administered epidurally has little effect on post-operative motor function. This combination can be used without concern of motor paralysis in healthy animals.

RESUMO

OBJECTIVE: To estimate the incidence of raised cTnI after general anaesthesia in dogs and to explore major risk factors influencing this. STUDY DESIGN: Prospective clinical study. Animals A total of 107 (ASA physical status 1-2) dogs, 63% male and 37% female, median age 5 years (range 0.3-13.4), median weight 24.4 kg (range 4.2-66.5 kg) undergoing anaesthesia for clinical purposes. METHODS: Venous blood samples were taken within 24 hours prior to induction and 24 hours after the termination of anaesthesia. Serum concentrations of cardiac troponin I were measured using a chemiluminescent enzyme immunometric assay with a lower level of detection of 0.20 ng mL(-1) (below this level <0.20 ng mL(-1)). Continuous data were assessed graphically for normality and paired and unpaired data compared with the Wilcoxon signed ranks and Mann-Whitney U-tests respectively. Categorical data were compared with the Chi squared or Fisher's exact test as appropriate (p < 0.05). RESULTS: Of the 107 dogs recruited, 100 had pre- and post-anaesthetic cTnI measured. The median pre-anaesthesia cTnI was '<0.20' ng mL(-1) (range '<0.20'-0.43 ng mL(-1)) and the median increase from pre-anaesthesia level was 0.00 ng mL(-1) (range -0.12 to 0.61 ng mL(-1)). Fourteen dogs had increased cTnI after anaesthesia relative to pre-anaesthesia (14%, 95% CI 7.2-20.8%, range of increase 0.03-0.61 ng mL(-1)). Six animals had cTnI levels that decreased (range 0.02-0.12 ng mL(-1)). Older dogs were more likely to have increased cTnI prior to anaesthesia (OR = 5.32, 95% CI 1.35-21.0, p = 0.007) and dogs 8 years and over were 3.6 times as likely to have an increased cTnI after anaesthesia (95% CI 1.1-12.4, p = 0.028). CONCLUSION AND CLINICAL RELEVANCE: Increased cTnI after anaesthesia relative to pre-anaesthesia levels was observed in a number of apparently healthy dogs undergoing routine anaesthesia.

RESUMO

A Great Dane bitch was treated for presumed primary uterine inertia with repeated doses of oxytocin and manually assisted whelping. She was diagnosed with uterine rupture and septic peritonitis the following day. The uterine rupture is hypothesized to have occurred as a result of the management strategy used to treat dystocia. The dog underwent ovariohysterectomy, and the septic peritonitis was managed with open peritoneal drainage. The dog recovered well and was discharged 5 days later. No previous reports of canine uterine rupture associated with manual intervention appear to have been published. This report highlights the potential dangers involved in such an approach.
