“…It would have been valuable to ascertain the opinions of private general practitioners regarding the types of procedures that a new graduate should be able to perform, but this was beyond the scope of the study. The synthetic canine model assessed in our study was designed to address limitations associated with the popular methods of veterinary surgical training, including the use of live animals, cadaveric tissue, and isolated low‐fidelity synthetic models, which include ethical concerns, lack of availability, and insufficient realism.…”

Survey of clinician and student impressions of a synthetic canine model for gastrointestinal surgery training

2019

View full text Add to dashboard Cite

Objective: To evaluate the perceived efficacy of a high-fidelity synthetic canine model for simulating common gastrointestinal surgical procedures. Study design: Survey of students and experienced clinicians. Sample population: Twelve clinicians with >2 years of postgraduate experience in the field of small animal surgery and 102 senior year veterinary students. Methods: The model was subjectively evaluated by 12 clinicians with >2 years of postgraduate experience in the field of small animal surgery. Senior year veterinary students (n = 102) were asked to complete questionnaires before and after a laboratory on common gastrointestinal surgical procedures that included rating of perceived proficiency, anatomical knowledge, and the use of synthetic models compared with live animals. Results: Clinicians assessed most aspects of the model as moderately realistic and unanimously agreed that it would be helpful for students to train on this model prior to live surgery. Student survey response rates were 91% and 99% before and after the laboratory, respectively. The proportion of students that felt moderatelyto-highly proficient with the procedures increased from 8% prior to the laboratories to 59% after the laboratories (P < .001). The proportion of students that felt that they had superior-to-excellent knowledge of abdominal surgical anatomy increased from 16% prior to the laboratories to 44% after the laboratories (P < .001). The proportion of students that were satisfied with synthetic models instead of live animals increased from 52% prior to the laboratories to 74% after the laboratories (P = .014). Conclusion: Experienced clinicians considered the model to have moderate realism. A positive shift in the students' self-perceived proficiency with gastrointestinal surgery was evident after the use of the model. Clinical impact: This synthetic model should be considered for training of veterinary gastrointestinal surgery. However, comparison studies are recommended to ascertain the relative educational value of this model.

“…Benefits of using surgical models or simulators include reduction of the number of live animals required to gain proficiency in the procedure, improving student confidence in performing a procedure prior to live‐animal experience, and reducing costs associated with live‐animal surgery . Studies evaluating ovariohysterectomy models have provided evidence that training with models improves performance and confidence compared with the standard curriculum without models .…”

Evaluation of surgical models for training veterinary students to perform enterotomies

Objective: To compare surgical models for teaching enterotomies to students.Study design: Prospective, randomized study. Sample population: Second-year veterinary students (n = 59) and faculty surgeons/surgery residents (n = 19). Methods: Participants performed an enterotomy on each of 3 models (equine cadaver intestine, SurgiReal small intestine simulator, and SynDaver canine bowel) and completed a survey comparing them to either an enterotomy on an anesthetized pig (students) or intestinal surgery experience (faculty/residents). Surveys results were compiled and analyzed. Results: Both student and faculty/resident groups rated cadaver intestine as more similar to live intestine compared with the synthetic models for incision, tissue handling, mucosal eversion, needle passage, knot tying, and best preparing for live intestine. Students rated SynDaver as more similar to live intestine than SurgiReal for incision and ranked SurgiReal as more similar to live intestine than SynDaver for mucosal eversion. There was no difference between the ranks assigned to SurgiReal and Syn-Daver for faculty/residents. Faculty/residents responded most often that cadaver intestine would be the model they recommend for training students. Conclusion: Cadaver intestine was the model most similar to live intestine for all variables tested. SurgiReal and SynDaver models were comparable to each other but did not simulate live intestine as well as cadaver intestine. Clinical significance: Cadaver intestine more closely approximated live intestine compared with either synthetic model. SurgiReal and SynDaver may be adequate alternatives if cadaver intestine is unavailable.

“…Stress has been associated with the surgical educational environment and may affect performance and learning . These combined concerns regarding complications and student stress have prompted the search for alternative teaching methods that allow veterinary students to experience common surgical procedures in a comfortable learning environment while conferring requisite skills transfer . Among those, OHE simulators available for surgical training include the canine OHE model (RescueCritters, Simi Valley, California), Canine Spay Simulator (Veterinary Simulator Industries, Calgary, Alberta, Canada), and Spay Manikin (Paws 2 Claws; Palmdale, California).…”

Survey of instructor and student impressions of a high‐fidelity model in canine ovariohysterectomy surgical training

et al. 2019

View full text Add to dashboard Cite

Objective: To evaluate the usefulness of a high-fidelity model for teaching ovariohysterectomy (OHE) to veterinary students. Study design: Longitudinal survey. Sample population: Clinicians with ≥2 years postgraduate experience in small animal surgery and a sophomore veterinary student population at 1 institution. Methods: Twelve clinicians evaluated the high-fidelity model for realism. Questionnaires were distributed to sophomore veterinary students prior to and after OHE training on the high-fidelity model (SynDaver Surgical Canine) and after performing OHE as primary surgeon with a live dog. Time for students to perform OHE (identify the first ovarian pedicle to transecting the uterine body) and number of technical errors (visceral injury, hemorrhage, loose ligatures) were compared between the model and live dog groups. Results: Evaluators rated the high-fidelity model as moderate-to-highly realistic.Students' confidence improved after practicing on the model in all critical steps and additionally improved after performing an OHE on a live dog. Time to complete the OHE on the model (mean ± SD,73.4 ± 27.1 minutes) and live dogs (83.0 ± 24.7 minutes) did not differ (P = .20). Frequency of hemorrhagic events (P = .77) and accidental visceral injury (P = .30) did not differ between the model and live dogs. However, fewer loose ligatures were placed in live dogs (23/64) compared with the model (22/37; P = .02). Conclusion:The high-fidelity model improved the confidence of sophomore students. The duration of OHE did not differ between the model and live dogs. Clinical impact: The high-fidelity model is valuable for improving confidence in veterinary students prior to live-dog OHE.

Efficacy of Teaching the Gambee Suture Pattern Using Simulated Small Intestine versus Cadaveric Small Intestine

Abstract: SSI is as effective as equine cadaveric small intestine tissue to teach the Gambee suture pattern to second year veterinary students. If cadaver tissue is unavailable or undesirable, SSI could be used to instruct suture placement techniques.
