ABSTRACT Objective To describe and validate an ophthalmic model for corneal transplantation and micro suture training using a bovine eyeball as a model. Methods For the training model, the eyeball was placed under the sanitary field placed on the ends of a common 3.5cm diameter cylindrical plastic container for corneal removal. A superficial circular incision was made, then 9cm curved Castroviejo scissors were used for complete corneal removal. The cornea was replaced in its original position, and 10-0 nylon thread was used to perform the sutures, with 9 equidistant stitches. Finally, the following criteria were evaluated: suturing time, time and quality progression in each attempt, dexterity and suturing improvement. Results The described model proved to be feasible and suitable for corneal micro suture training, allowing improvement and gain of dexterity in the sport. Conclusion The presented microsurgical training model has a high feasibility for the simulation of ophthalmic surgeries, in addition to a texture similar to the real human eye, which makes it close to reality.

ABSTRACT

ABSTRACT Purpose: To describe a new accessible model of ophthalmological training using chicken eggs. Methods: With the aid of a spherical drill, the external calcified layer and the cuticle of the chicken eggshell were removed in a 2cm diameter circle. Using a video-magnification system, the film was dissected and cut to approximately 1.5 cm diameters. The film was removed and repositioned to make interrupted 12-0 nylon microsutures. The parameters analyzed were: cost, facility of acquisition and handling, time for making the model and the microsutures and number of possible uses. Results: In all simulators, it was possible to carry out separated and equidistant micro-sutures in the egg membrane, without the need for reintervention. Conclusion: The new chicken-egg model for ophthalmic surgery training is low-cost, easy to acquire and handle, and viable for the development of basic microsurgery skills.

ABSTRACT

Abstract Objective To evaluate the impact of systematic laparoscopic skills and suture training (SLSST) on the total laparoscopic hysterectomy intra- and postoperative outcomes in a Brazilian teaching hospital. Methods A cross-sectional observational study in which 244 charts of total laparoscopic hysterectomy (TLH) patients operated from 2008 to 2014 were reviewed. Patient-specific (age, parity, previous cesarean sections, abdominal surgeries and endometriosis) and surgery-related variables (hospital stay, operative time, uterine volume and operative complications) were analyzed in three different time-frame groups: 2008-09 (I-1) - TLHs performed by senior attending physicians; 2010-11 (I-2) - TLHs performed by residents before the implementation of the SLSST program; and 2012-14 (I-3) - TLHs performed by residents after the implementation of the SLSST program. Results A total of 244 TLH patients (mean age: 45.93 years) were included: 24 (I-1), 55 (I-2), and 165 (I-3). The main indication for TLH was uterine myoma (66.4%). Group I-3 presented a decrease in surgical time compared to group I-2 (p=0.010). Hospital stay longer than 2 days decreased in group I-3 compared to group I-2 (p=0.010). Although we observed decreased uterine volume (154.2 cm3) in group I-2 compared to group I-1 (217.8 cm3) (p=0.030), logistic regression did not find any association between uterine volume and surgical time (p=0.103). Conclusion The total operative time for laparoscopic hysterectomy was significantly shorter in the group of patients (I-3) operated after the systematic laparoscopic skills and suture training was introduced in our hospital.


Resumo Objetivo Avaliar o impacto do treinamento laparoscópico sistematizado de habilidades e sutura (TLSHS) nos resultados intra e pós-operatórios da histerectomia laparoscópica em um hospital universitário brasileiro. Métodos Estudo observacional transversal de revisão de 244 prontuários de pacientes submetidas a histerectomia total laparoscópica (HTL) operadas entre 2008 e 2014. Os fatores específicos das pacientes (idade, paridade, cesariana prévia, cirurgias abdominais, e endometriose) e as variáveis relacionadas à cirurgia (tempo de hospitalização, tempo de cirurgia, volume uterino e complicações operatórias) foram analisados em três grupos temporais: 2008-09 (I-1) - HTLs realizadas por médicos experientes; 2010-11 (I-2) - HTLs realizadas por residentes sem TLSHS; 2012-2014 (I-3) - HTLs realizadas por residentes após a implementação do TLSHS. Resultados Um total de 244 pacientes submetidas a HTLs foram incluídas (média de idade de 45,93 anos): 24 operadas no período I1, 55 no I2, e 165 no I3. A principal indicação para HTL foi mioma uterino (66,4%). O grupo I-3 apresentou diminuição no tempo cirúrgico quando comparado ao grupo I-2 (p=0,010). Hospitalização superior a 2 dias diminuiu no grupo I-3 comparado ao grupo I-2 (p=0,010). Apesar de observarmos diminuição no volume uterino dos pacientes do grupo I-2 (154,2 cm3) em comparação com os do grupo I-1 (217,8 cm3) (p=0,030), a regressão logística não revelou associação entre volume uterino e tempo cirúrgico (p=0,103). Conclusão O tempo cirúrgico na HTL foi significativamente menor no grupo de pacientes submetidas à cirurgia após a implantação do TLSHS em nosso hospital.

ABSTRACT

INTRODUCCIÓN: Las técnicas de sutura básicas se consideran competencias mínimas de un egresado de medicina y son fundamentales en el ejercicio de la medicina general. Actualmente, los estudiantes de la Universidad de Concepción no poseen una instancia formal para adquirir estas competencias. OBJETIVOS: Evaluar la validez de un programa de formación de alumnos monitores de sutura a través de los resultados obtenidos mediante un método de evaluación estandarizado, realizado en estudiantes de pregrado de medicina de la Universidad de Concepción. METODOLOGÍA: Estudio preexperimental antes y después. Se realizó intervención teórico-práctica para seis estudiantes de medicina de distintos semestres cursados, entre los meses de mayo y julio de 2017. Consistió en tres módulos: clases teóricas, práctica en modelo biológico y módulo en pabellón quirúrgico supervisado por subespecialistas. Se evaluó punto de sutura continuo y discontinuo en modelo biológico mediante la escala "The Objective Structured Assessment Of Technical Skills" (OSATS). Se describen y comparan resultados de la escala OSATS antes y después del curso. Se aplicó consentimiento informado. Se utilizó SPSS® para análisis estadístico mediante prueba de Mann-Whitney para variables no paramétricas. Se consideró significativo p < 0,05. RESULTADOS: Todos los participantes mejoraron puntuación en escala OSATS. Los participantes progresaron significativamente sus resultados en las distintas escalas OSATS (5,2 vs 8,8; p < 0,05 y 16,5 vs 27,2; p < 0,05) al comparar resultados pre vs posintervención respectivamente. DISCUSIÓN: Nuestra experiencia demuestra que es posible crear un taller de formación de MS con muy buenos resultados, para estudiantes de medicina, a través de una capacitación trimodal, con clases teóricas, simulación y práctica in vivo. Además, constituye la base de futuras investigaciones que buscan solucionar la inexistencia de un programa formal de enseñanza de técnicas de sutura a los estudiantes de medicina de nuestra facultad.


INTRODUCTION: Suture techniques are considered the minimum of a medical examination and are fundamental in the practice of medicine. Currently, the students of the Universidad de Concepción do not have a formal instance to acquire these competences. AIM: To evaluate the validity of a training program for Suture Instructor (SI) students through the results obtained through a standardized assessment method, carried out in undergraduate students of medicine at the University of Concepción. METHOD: Preexperimental before and after study. A theoretical-practical intervention was carried out for six medical students of different semesters of the career, between the months of May and July 2017. It consisted of three modules: theoretical classes, practice in biological model and module in surgical pavilion supervised by subspecialists. Continuous and interrupted sutures were evaluated in the biological model using the "The Objective Structured Assessment of Technical Skills" (OSATS) scale. Results of the OSATS scale are described and compared before and after the course. Informed consent was applied. SPSS® was used for statistical analysis by Mann-Whitney test for non-parametric variables. It was considered significant p < 0.05. Results: All participants improved score on OSATS scale. The participants progressed significantly their results in the different OSATS scales (5.2 vs 8.8, p < 0.05 and 16.5 vs 27.2, p < 0.05) when comparing pre vs post intervention results respectively. DISCUSSION: Our experience shows that it is possible to create an SI training workshop with excellent results for medical students, through a three phase training program, with theory classes, simulation and "in vivo" practice. It also constitutes the basis of future research that seeks to solve the lack of a formal program of teaching suture techniques to medical students of our university.

ABSTRACT

Abstract Purpose: To develop a silicone alternative model of tissue suture simulation to be used in the teaching of surgical technique. Methods: Twelve alternative models of silicone for tissue suture simulation were manufactured and implemented as a tool for suture pattern training of undergraduate medical students of Universidade Federal do Amazonas. Forty-eight students participated in the research. The evaluation of the proposed model was done through a questionnaire using the Likert scale, in order to verify the student satisfaction index of the alternative resource and its performance as opposed to the model historically used in the discipline, which is to suture in cloths. Results: The alternative model showed satisfactory results, especially with respect to the structural aspect, such as, better perception of anatomical planes, handling and transport. About 89.58% of positive concordant responses demonstrating expressive approval for incorporation of a complementary form of the alternative methodological proposal of the discipline of surgical technique. Conclusions: The model developed for experimental simulation of tissue sutures has proved to be a fully feasible alternative method for the training of this surgical skill. It is a simple, reproducible and low-cost model.

ABSTRACT

Abstract Objective To describe and evaluate the use of a simple, low-cost, and reproducible simulator for teaching the repair of obstetric anal sphincter injuries (OASIS). Methods Twenty resident doctors in obstetrics and gynecology and four obstetricians participated in the simulation. A fourth-degree tear model was created using lowcost materials (condom simulating the rectal mucosa, cotton tissue simulating the internal anal sphincter, and bovine meat simulating the external anal sphincter). The simulator was initially assembled with the aid of anatomical photos to study the anatomy and meaning of each component of the model. The laceration was created and repaired, using end-to-end or overlapping application techniques. Results The model cost less than R$ 10.00 and was assembled without difficulty, which improved the knowledge of the participants of anatomy and physiology. The sutures of the layers (rectal mucosa, internal sphincter, and external sphincter) were performed in keeping with the surgical technique. All participants were satisfied with the simulation and felt it improved their knowledge and skills. Between 3 and 6 months after the training, 7 participants witnessed severe lacerations in their practice and reported that the simulation was useful for surgical correction. Conclusion The use of a simulator for repair training in OASIS is affordable (low-cost and easy to perform). The simulation seems to improve the knowledge and surgical skills necessary to repair severe lacerations. Further systematized studies should be performed for evaluation.


Resumo Objetivo Descrever e avaliar a utilização de um simulador simples, de baixo custo e reprodutível para o ensino de sutura de lacerações perineais de 4° grau. Métodos Participaram da simulação 20 residentes de ginecologia e obstetrícia e quatro profissionais especialistas. Um modelo de laceração de 4° grau foi criado com materiais de baixo custo (preservativo simulando a mucosa retal, tecido de algodão simulando o esfíncter anal interno e carne bovina simulando o esfíncter anal externo). O simulador foi inicialmente montado com ajuda de fotos anatômicas, para estudar a anatomia e o significado de cada componente do modelo. A laceração foi criada e suturada, utilizando técnicas de borda a borda e de sobreposição do esfíncter anal. Resultados O modelo custou menos de R$ 10,00 e foi montado sem dificuldade, aprimorando os conhecimentos dos participantes sobre anatomia e fisiologia. As suturas das camadas (mucosa retal, esfíncter interno e esfíncter externo) foram realizadas seguindo a técnica cirúrgica. Todos os participantes ficaram satisfeitos coma simulação e consideraram que estamelhorou seus conhecimentos e habilidades. Entre 3 a 6 meses após o treinamento, 7 participantes presenciaram em sua prática lacerações graves e relataram que a simulação foi útil para a correção cirúrgica. Conclusão A utilização de um simulador para treinamento de sutura de lacerações obstétricas graves é acessível (baixo custo e fácil execução). A simulação parece aprimorar conhecimentos e habilidades cirúrgicas para sutura de lacerações graves. Mais estudos sistematizados devem ser realizados para avaliação.

ABSTRACT

Abstract Objective To assesswhether themonomanual or bimanual training of laparoscopic suture followingthe sametechniquemay interferewith theknots' performancetimeand/or quality. Methods A prospective observational study involving 41 resident students of gynecology/ obstetrics and general surgery who attended a laparoscopic suture training for 2 days. The participants were divided into two groups. Group A performed the training using exclusively their dominant hand, and group B performed the training using both hands to tie the intracorporeal knot. All participants followed the same technique, called Romeo Gladiator Rule. At the end of the course, the participants were asked to perform three exercises to assess the time it took them to tie the knots, as well as the quality of the knots. Results A comparative analysis of the groups showed that there was no statistically significant difference (p = 0.334) between them regarding the length of time to tie one knot. However, when the time to tie 10 consecutive knots was compared, group A was faster than group B (p = 0.020). A comparison of the knot loosening average, in millimeters, revealed that the knots made by group B loosened less than those made by group A, but there was no statistically significant difference regarding the number of knots that became untied. Conclusion This study demonstrated that the knots from group B showed better quality than those from group A, with lower loosening measures and more strength necessary to untie the knots. The study also demonstrated that group A was faster than B when the time to tie ten consecutive knots was compared.


Resumo Objetivo O objetivo deste estudo é avaliar se o treinamento monomanual ou bimanual de sutura laparoscópica seguindo a mesma técnica pode interferir no tempo de realização e/ou qualidade dos nós. Métodos Estudo prospectivo observacional envolvendo 41 estudantes residentes de ginecologia /obstetrícia e cirurgia geral que participaram de um treinamento de sutura laparoscópica por 2 dias. Os participantes foram divididos em dois grupos. O grupo A realizou o treinamento usando exclusivamente amão dominante, e o grupo B realizou o treinamento usando as duas mãos para amarrar o nó intracorpóreo. Todos os participantes seguiram a mesma técnica, chamada Regra do Gladiador, descrita por Armando Romeo. No final do curso, os participantes foram convidados a realizar três exercícios para avaliar o tempo de realização e a qualidade dos nós. Resultados Uma análise comparativa dos grupos mostrou que não houve diferença estatística significativa (p = 0,334) entre eles quanto ao período de tempo para amarrar um nó. No entanto, quando o tempo para amarrar 10 nós consecutivos foi comparado, o grupo A foi mais rápido do que o grupo B (p = 0,020). A comparação da média de afrouxamento de nó, em milímetros, revelou que os nós do grupo B afrouxaram menos do que os do grupo A, mas não houve diferença estatística significativa quanto ao número de nós que desamarraram. Conclusão Este estudo demonstrou que os nós do grupo B apresentaram melhor qualidade do que os nós do grupo A, com menores medidas de afrouxamento e maior força necessária para desamarrar os nós. Também demonstrou que o grupo A foi mais rápido do que B quando o tempo para amarrar dez nós consecutivos foi comparado.

ABSTRACT

Abstract Purpose: To develop and test a model of teaching by means of an abdominal cavity simulator. Methods: This study had two stages: development of a teaching model and an experimental prospective study that aimed to evaluate the residents' competence. The participants were divided into 3 groups: first-year resident, second-year resident, and senior surgeon. The two groups of resident physicians received training in the simulator, under instructor supervision for skill acquisition, according to the model proposed in first stage. The surgeons did not receive this intervention. The correlations and associations were verified through simple and multiple linear regressions. The learning curves were analysed using Cox regression models. The impact of the epidemiological characteristics was tested. Results: All residents reached the maximum score at the end of 16 steps and were comparable to the experimental (p<0.001). Conclusion: Residents who underwent training using the methodology of the proposed teaching model, which is based on realistic simulation, acquired proficiency in the accomplishment of endosutures in up to 16 hours of training in the laboratory.

ABSTRACT

ABSTRACT Background : Laparoscopic manual suturing is probably the most difficult skill to be acquired in minimally invasive surgery. However, laparoscopic exercise endo-sutures can be learned with a simulator and are of great practical importance and clinical applicability, absorbing concepts that are immediately transferred to the operating room. Aim : To assess the progression of skills competence in endo-sutures through realistic simulation model of systematized education. Method : Evaluation of the progression of competence of students in three sequential stages of training in realistic simulation, pre-test (V.1), teaching concepts (V.2) and training station for absorption of video concepts in surgery - ergonomics, stereotaxia, ambidexterity, haptic touch, fucral effect, applied in the manufacture of points corresponding to a Nissen fundoplication, in endo-suture for realistic simulation. Results : All students who attended the course absorbed the video concepts in surgery; most participants showed steady and continued improvement and during the stages of training, obtained progression of appropriate skills, defining competence and validation of the teaching model to achieve proficiency. Conclusions : The teaching model was adequate, safe, revealed the profile of the student, the evolutionary powers of the endo-sutures performance and critical analysis of the training to achieve proficiency in bariatric procedures.


RESUMO Racional : A sutura manual laparoscópica é, provavelmente, a habilidade mais difícil de ser adquirida na cirurgia minimamente invasiva. No entanto, os exercícios laparoscópicos de endossuturas podem ser aprendidos com um simulador e se revestem de grande importância prática, haja vista que tem aplicabilidade clínica, sendo os conceitos absorvidos e transferidos imediatamente para a sala de operação. Objetivo : Avaliar a progressão decompetência de habilidades em endossuturas através de simulação realística em modelo de ensino metodizado. Método : Avaliação da progressão de competência dos alunos em três etapas sequenciais de treinamento em simulação realística, pré-teste (V.1), ensinamento dos conceitos (V.2) e estação de treinamento para absorção dos conceitos de videocirurgia - ergonomia, estereotaxia, ambidestria, hapticidade (movimento preciso de instrumentoscom as mão, sem o auxílio ou comando da visão), efeito fucral (movimento invertido de uma balança ou alavanca a partir de um ponto central), aplicados na confecção de pontos correspondentes à fundoplicatura de Nissen em endossutura por simulação realística. Resultados : Todos os alunos que participaram do curso absorveram os conceitos de videocirurgia; a maioria apresentou melhora constante e continuada, e no decorrer das etapas do treinamento,obtiveram progressão de habilidades adequadas, definindo competência e validação do modelo de ensino para atingir a proficiência. Conclusões : O modelo mostrou-se adequado, seguro, revelou o perfil do aluno, a competência evolutiva da performance em endossuturas e análise crítica da carga de treinamento para evoluir até atingir a proficiência nos procedimentos bariátricos.

ABSTRACT

Abstract Purpose: To introduce a nonliving microvascular training model based on vessels diameter and feasibility. Methods: We dissected ten oxen tongues, and divided the pedicles into three-thirds: proximal, middle and distal. We measured the external vessels diameter in all regions. We performed a descriptive statistical analysis. Three students (two beginner level and one intermediate level) performed this training. We evaluated the confidence, according Likert scale. Results: We dissected all oxen tongues, each tongue showed two parallel pedicles. Each pedicle was located at 1.5 - 2.0 cm from the midline. Proximal median artery and vein diameter were 3.9 ± 0.7, and 5.04 ± 1.44mm, respectively. In the middle third, the mean artery diameter was 3.3 ± 0.4mm, and the vein diameter was 3.5 ± 0.9mm. The distal third showed a mean artery diameter of 2.0 ± 0.42mm, and a vein diameter of 2.4 ± 0.82mm. The students performed ten anastomoses. This study showed a higher confidence level (CL) (p=0.03) than the pre training CL assessment. Conclusion: This study suggested a feasible non-animal model for microsurgical training process for beginners and intermediate trainees.

ABSTRACT

Abstract Purpose: To follow-up the development of medical students in taking a stitch using two different bench models, and to assess their performance with regards to gender, handedness, prior recreational activities and interest in surgery. Methods: The study was performed during the compulsory basic (n=152) and the consecutive elective course (n=27). Students took simple interrupted stitches into synthetic and biopreprate models in the classroom and in the operating room. The time needed for that was measured and the quality was scored, using an OSATS (Objective Structured Assessment of Technical Skill) checklist that had been adapted to our training programs. Results: Students' performance improved both in time and quality during classes, over the course and compared basic to the elective course, too. No significant difference was found in relation to gender and handedness but certain recreational activities and special interest in surgery led to better results. Operating room environment had a slight negative effect on students' performance. Conclusion: The study could provide objective skill assessment, monitoring has revealed deficiencies and influencing factors. Objective feedback, valid and reliable assessment is important in teaching surgical skills. In addition it may contribute to higher surgical safety later on in the clinical practice.

Introduction: Simulation has demonstrated utility in suture skills training on surgical residents. Objective: Evaluate validity of a simulated training curriculum of basic suture skills for medical students. Methods: Study conducted on 2013. Medical students were selected from the School of Medicine of Pontificia Universidad Católica de Chile (EMPUC). The program included four theoretical sessions and six practical sessions in order to training basic surgical tasks (five in total) on a simulated rubber model: one handed knot-tying, simple suture, vertical mattress suture, subcuticular interrupted suture and subcuticular running suture. A survey was applied to the participants to qualify each element of the program, on a scale of 1 to 7 (face-validity). One task (simple suture) was recorded on video, before and after training, to be evaluated by two experts on a blind fashion (content validity). Experts measure participant skills using an OSATS (Objective Structured Assessment of Technical Skills) and operative time. Statistical analysis for non-parametric variables, median and interquartile range, significant p-value < 0.05. Results: Thirty-six medical students participated, with assistance percentage was over 80 percent. Students qualified the experience favorably: simulated bench-model 6.0 [5.0-6.0], assistant-students 6.5 [6.0-7.0], practical sessions 7.0 [6.0-7.0], and general evaluation 6.5 [6.0-7.0]. In the evaluation of simple suture, there was a significant improvement on OSATS (10 [5-17] vs 19 [17-21]; p < 0.001) and decrease of operative time (138 seg [101-185] vs 77 seg [67-89]; p < 0.001) after training in every participant. Conclusion: This simulated curriculum delivers an alternative method for the development of technical competencies in medical students and could be incorporated on medical schools curricula.


Introducción: La simulación ha demostrado ser útil en la enseñanza de técnicas de sutura en cirujanos en formación. Objetivo: Evaluar la validez de un programa de entrenamiento simulado de técnica básica de sutura para estudiantes de pregrado de medicina. Material y Métodos: Estudio experimental realizado el año 2013, se seleccionó estudiantes de pregrado de la Escuela de Medicina de la Pontificia Universidad Católica de Chile (EMPUC).

ABSTRACT

Objectives: The purpose of this paper is to develop a simple and cost‑effective suturing training model. Materials and Methods: A simplified suturing model is developed for preclinical training purpose. The training model requires only three easily available materials, which include synthetic foam sponge, elastomeric impression material and putty impression material. Construction of this model requires only 15 min. Results: The training model thus developed resembles a realistic human tissue with a skin analog, deeper connective tissues and a bony base. This enables the students to practice various suturing technique at different tissue planes. Such practice helps the students to perform a live procedure in a more skilled and less traumatic way. Conclusion: The easy availability and cost‑effective nature of the materials, in concert with fast construction time, makes this suturing model appropriate when an affordable alternative is desired.

ABSTRACT

PURPOSE: To demonstrate an experimental model of up to four hours a week of independent study that allows relearning in microvascular sutures. METHODS: Wistar rats between 200 and 500 grams surplus research experiments were used. Femoral vessels are covered on one or both sides through a groin incision obliquely along the inguinal ligament. Femoral artery and vein are isolated and measured being clamped and cut. The individual performs in microvascular anastomosis complexity arterial and venous terminoterminal sequence. terminolateral and venous and arterial grafts in vessels. Permeability is evaluated by testing vascular patency after creation of microvascular anastomosis. RESULTS: In the first specimen, only arterial and venous vascular anastomosis are performed terminoterminal. The average diameter of the femoral veins varies from 0.8 to 2 mm between rodents (artery, between 0.6 and 1.4 mm, between 0.8 and 2 mm vein). The superficiality of the vessels allows faster dissection, may also be held in other inguinal region. CONCLUSION: The model of individual retraining allows learning microvascular suture in individuals of permanent staff. .

ABSTRACT

OBJECTIVE: Although several inanimate bench models have been described for training of suture skills, so far, there is no ideal method for teaching and learning this skill during medical education. The aim was to evaluate whether bench model fidelity interferes in the acquisition of suture skills by novice medical students. METHODS: 36 medical students with no surgical skills' background (novices) were randomized to three groups (n = 12): theoretical suture training alone (control); low-fidelity suture training model (synthetic ethylene-vinyl acetate bench model); or high-fidelity suture training model (pig feet skin bench model). Pre- and post-tests were applied (performance of simple interrupted sutures and subdermal interrupted sutures on ox tongue). Three tools (Global Rating Scale with blinded assessment, effect size, and self-perceived confidence based on Likert scale) were used to measure all suture performances. RESULTS: The post-training analysis showed that the students that practiced on bench models (hands-on training) presented better (all p < 0.0000) performance in the Global Rating Scale evaluation, compared with the control, regardless of the model fidelity. The magnitude of the effect (training) was considered large (> 0.80) in all measurements. Students felt more confident (all p < 0.0000) to perform both types of sutures after training. CONCLUSION: The acquisition of suture skills on the low-fidelity bench model was similar to that of the high-fidelity bench model, and the increase in the performance of participants that received bench model training was superior to those who received training based on theoretical teaching materials.


OBJETIVO: Embora vários modelos de bancada inanimados tenham sido descritos para o treinamento de habilidades de sutura, até o momento, não existe um método ideal para esse ensino e aprendizagem durante a formação médica. O objetivo foi avaliar se a fidelidade dos modelos de bancada interfere na aquisição de habilidades de sutura em estudantes de medicina iniciantes na prática cirúrgica. MÉTODOS: 36 estudantes de medicina sem exposição prévia a habilidades cirúrgicas foram randomizados em três grupos (n = 12): treinamento de suturas baseado em materiais didáticos (controle); treinamento de suturas em modelo de baixa-fidelidade (modelo de bancada de etileno vinil acetato); ou treinamento de suturas em modelo de alta-fidelidade (modelo de bancada de pele de pata de porco). Foram aplicados pré e pós-testes (realização de pontos simples e pontos subdérmicos invertidos em língua de boi). Três ferramentas (Global Rating Scale com avaliação cega, tamanho do efeito e autopercepção da confiança baseada em uma escala de Likert) foram utilizadas para mensurar todas as performances de sutura. RESULTADOS: A análise após o treinamento demonstrou que os estudantes que treinaram nos modelos tiveram um melhor (p < 0.0000) desempenho na avaliação pela Global Rating Scale, quando comparados com o controle, independente da fidelidade do modelo. A magnitude do efeito (treinamento) foi considerada grande (> 0.80) em todas as mensurações. Após o treinamento os alunos sentiram-se mais confiantes (p < 0.0000) para executarem os dois tipos de suturas. CONCLUSÃO: A aquisição de habilidades de suturas no modelo de baixa fidelidade foi semelhante à prática no modelo de alta fidelidade, sendo que a melhora no desempenho dos participantes que treinaram nesses dois modelos foi superior à aprendizagem baseada em materiais didáticos.

ABSTRACT

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<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<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.


OBJETIVO: Avaliar a aquisição das habilidades de sutura com o treinamento no modelo de bancada de etileno vinil acetato em acadêmicos de medicina. MÉTODOS: Dezesseis estudantes de medicina iniciantes na prática cirúrgica foram divididos aleatoriamente em dois grupos. Durante uma hora o grupo A treinou diferentes suturas no modelo de bancada de etileno vinil acetato (EVA) com feedback dos instrutores, enquanto os do grupo B (controle) receberam um treinamento dirigido por instrutor baseado em livros e vídeos didáticos. Todos foram submetidos à pré e pós-testes para realização de suturas bi e tridimensionais em língua de boi. As performances gravadas foram avaliadas por dois avaliadores cegos, utilizando a Global Rating Scale. RESULTADOS: Embora os dois grupos tenham apresentado um melhor desempenho (p<0.05) no pós-teste quando comparado com o pré-teste, a análise do pós-teste mostrou que os alunos do grupo A (EVA) tiveram um melhor desempenho (p<0.05) quando comparados com os do grupo B (controle). CONCLUSÃO: O modelo de etileno vinil acetato permitiu que os alunos adquirissem habilidades de sutura mais rapidamente quando comparado ao modelo tradicional de ensino.
