This article details the rise of surgical robots in the human surgical sphere as well as their use in veterinary medicine. Sections will describe in detail the equipment required for these procedures ...and the advantages and disadvantages of their use. Specific attention is given to the articulated instrumentation, which affords psychomotor benefits not only for surgical precision but also for surgeon ergonomics. A discussion of the possible indications and current use of robotics in veterinary medicine and the challenges to integrating robotics is also provided.
Veterinary minimally invasive surgery continues to grow as a specialty. With increasing experience in this field, comes improved accessibility as well as progressive complexity of procedures ...performed. Advancement in technology has been both a response to the growth and a necessary driver of continued refinement of this field. Innovative research leading to advancements in surgical equipment has led to the development of novel image acquisition platforms, cannulas, smoke evacuation systems, antifog devices, instrumentation, and ligating/hemostatic devices. These innovations will be reviewed and potential clinical applications are discussed.
REASONS FOR PERFORMING STUDY: Multicentre Confidential Enquiries into Perioperative Equine Fatalities (CEPEF) have not been conducted since the initial CEPEF Phases 1–3, 20 years ago. OBJECTIVES: To ...collect data on current practice in equine anaesthesia and to recruit participants for CEPEF‐4. STUDY DESIGN: Online questionnaire survey. METHODS: An online questionnaire was prepared and the link distributed internationally to veterinarians possibly performing equine anaesthesia, using emails, posters, flyers and an editorial. The questionnaire included 52 closed, semiclosed and open questions divided into 8 subgroups: demographic data, anaesthetist, anaesthesia management (preoperative, technical equipment, monitoring, drugs, recovery), areas of improvements and risks and motivation for participation in CEPEF‐4. Descriptive statistics and Chi‐squared tests for comparison of categorical variables were performed. RESULTS: A total of 199 questionnaires were completed by veterinarians from 14 different countries. Of the respondents, 43% worked in private hospitals, 36% in private practices and 21% in university teaching hospitals. In 40 institutions (23%) there was at least one diplomate of the European or American colleges of veterinary anaesthesia and analgesia on staff. Individual respondents reported routinely employ the following anaesthesia monitoring modalities: electrocardiography (80%), invasive arterial blood pressures (70%), pulse oximetry (60%), capnography (55%), arterial blood gases (47%), composition of inspired and expired gases (45%) and body temperature (35%). Drugs administered frequently or routinely as part of a standard protocol were: acepromazine (44%), xylazine (68%), butorphanol (59%), ketamine (96%), diazepam (83%), isoflurane (76%), dobutamine (46%), and, as a nonsteroidal anti‐inflammatory drug, phenylbutazone (73%) or flunixin meglumine (66%). Recovery was routinely assisted by 40%. The main factors perceived by the respondents to affect outcome of equine anaesthesia were the preoperative health status of the animal and training of the anaesthetist. CONCLUSIONS: Current practice in equine anaesthesia varies widely, and the study has highlighted important topics relevant for designing a future prospective multicentre cohort study (CEPEF‐4).

Objective
To evaluate the influence of instructor to student ratio on the effectiveness and efficiency of teaching suturing skills to veterinary students.
Study design
Prospective randomized study.
...Sample population
Second‐year veterinary students (N = 121).
Methods
Students were randomly divided into three groups to participate in four 2‐hour skills laboratory sessions in which suturing of the subcutaneous tissue was taught by using a simple continuous pattern, suturing of the skin was taught by using continuous patterns, suturing of the skin was taught by using interrupted patterns, and suturing of hollow organs was taught by using inverting patterns. For each laboratory, the groups were taught by using instructor‐to‐student ratios of 1:6, 1:8, and 1:10 on a rotating basis. Students were surveyed at the end of each laboratory, and underwent individual performance assessments at the end of each laboratory session and again at the end of the semester in an objective structured clinical examination (OSCE).
Results
For each of the four in‐laboratory assessments and the OSCE, no difference in performance was detected between groups. When they were surveyed, students in all groups reported that there was an adequate number of instructors in the laboratory and that they received help in a timely fashion when help was requested (median for all groups = agree).
Conclusion
For students with prior surgical skills education and with the use of prelaboratory instructional videos, teaching at the 1:10 instructor‐to‐student ratio was efficient and effective.
Clinical significance
Good educational outcomes may be reached with a 1:10 instructor‐to‐student ratio or, potentially, fewer instructors, depending on the educational aids present in the laboratory and students' prior level of experience.
This study evaluated whether one supervised simulated ovariohysterectomy (OVH) using a locally developed canine OVH model, decreased surgical time for final-year veterinary students' first ...live-animal OVH. We also investigated student perceptions of the model as a teaching aid. Final-year veterinary students were exposed to an OVH model (Group M,
= 48) and compared to students without the exposure (Group C,
= 58). Both groups were instructed similarly on performing an OVH using a lecture, student notes, a video, and a demonstration OVH performed by a veterinary surgeon. Students in Group M then performed an OVH on the model before performing a live-animal OVH. Students in Group C had no exposure to the OVH model before performing a live-animal OVH. Surgical time data were analyzed using linear regression. Students in Group M completed a questionnaire on the OVH model after performing their first live-animal OVH. The OVH model exposure reduced students' first canine live-animal OVH surgery time (
= .009) for students without prior OVH experience. All students (
= 48) enjoyed performing the procedure on the mode; students practicing an OVH on the model felt more confident (92%) and less stressed (73%) when performing their first live-animal OVH. Results suggest that the canine OVH model may be helpful as a clinical training tool and we concluded that the OVH model was effective at decreasing students' first OVH surgical time.
