Training on synthetic ethylene-vinyl acetate bench model allows novice medical students to acquire suture skills

Abstract

<jats:p>PURPOSE: To assess the acquisition of suture skills by training on ethylene-vinyl acetate bench model in novice medical students. METHODS: Sixteen medical students without previous surgery experience (novices) were randomly divided into two groups. During one hour group A trained sutures on ethylene-vinyl acetate (EVA) bench model with feedback of instructors, while group B (control) received a faculty-directed training based on books and instructional videos. All students underwent a both pre-and post-tests to perform two-and three-dimensional sutures on ox tongue. All recorded performances were evaluated by two blinded evaluators, using the Global Rating Scale. RESULTS: Although both groups have had a better performance (p&lt;0.05) in the post-test when compared with the pre-test, the analysis of post-test showed that group A (EVA) had a better performance (p&lt;0.05) when compared with group B (control). CONCLUSION: The ethylene vinyl acetate bench model allowed the novice students to acquire suture skills faster when compared to the traditional model of teaching.</jats:p>

Surgical model pig ex vivo for venous dissection teaching in medical schools

“…The application of OSATS [7][8][9] Scale showed significant differences between the mean values obtained in the evaluation of skills by groups, it is interesting to note that the group A averaged markedly higher than in Group B on four of the six variables and the overall average favored the group A. Even so, each individual variable analyzed in both groups reached averages> 2.6 considering the results "satisfactory".…”

“…The results of measurements obtained from the application of OSATS [7][8][9] Scale for estimation of developed surgical skills are shown in Table 2. There were no previous results than the minimum standards established in the research, both theoretical advantage as to the practical in either group (Table 3).…”

“…This criterion established SATISFACTION parameter to our research. Surgical skills estimated by the scale of objective structured assessment of technical skills (OSATS) [7][8][9] in students, had six variables evaluated with values from one to five, setting 2.6 as a parameter of "satisfaction" for each variable, adding a total of 30 points, regarded as "satisfactory" all score above 16 points (Table 1).…”

“…Therefore, since there are studies developed by our group [36–38] and by others [80–83] that demonstrate objectively that the surgical skills learned by novice undergraduate on bench models can result in improved performance in animals, corpses, and also in the operating room, regardless of the fidelity of bench model [9, 38, 39, 80–83], the choice of a specific bench model should not be based on its fidelity. Aspects such as availability, seasonal variability, and costs should be considered for this choice.…”

“…Nele, não há produção de secreções nem putrefação em decorrência da colonização por microorganismo, o que traz benefícios com relação à logística, ao contágio e ao armazenamento. Também, não há risco de contágio ou transmissão de doenças infectocontagiosas 6 . Esse modelo fornece a praticidade de ser reprodutível, de baixo custo e de fácil aquisição.…”
