Evaluación de la calidad del cierre de piel en modelos murinos realizada por alumnos de grado en Medicina.

Abstract

Introduction: It should be analyzed regularly: what, how and who should teach surgery in undergraduate students; a factor that forces us to improve surgical teaching is the recognition that the patient can have adverse effects. Objective: evaluate the quality of abdominal wall closure in murine models performed by undergraduate students. Materials and Methods: Analytical, prospective, and cross-sectional observational study. A universe was 55 students, of which only 35 selected alumnus were included, who were evaluated on Winstar rat-type mouse models, taking as variables the closure of the abdominal wall and the grades according to the Anaya and Serrano questionnaire. Results: 35 skin closures with average lengths of length 5.4 cm and width 0.53 cm were evaluated, 23 (65.7 %) and poor quality 12 (34.3 %) were rated as quality. A proportion of quality closures is observed in approved undergraduate students (f=18, 78.3%) and non-approved (f=5, 21.7%). A proportion of non-quality closures in approved undergraduate students (f=8, 66.7%) and non-approved (f=4, 33.3%). Discussion: Unsuccessful abdominal wall closures in mouse models are not related to failing grades in undergraduate students in our study, however, the objective for which we wanted to evaluate this skill quantitatively was met. Introducción: Se debe mejorar la docencia quirúrgica, siempre en beneficio del paciente, para que no curse con efectos adversos. Ojetivo: Evaluar la calidad del cierre de pared abdominal en modelos murinos realizada por alumnos del grado en medicina. Métodos: Estudio observacional analítico, prospectivo y transversal. Se consideró conjunto universo a 55 alumnos de los cuales solo se incluyen a 35 seleccionados, a los que se les evalúo sobre modelos murinos tipo ratas Winstar, tomando como variables el cierre de pared abdominal y las calificaciones según el cuestionario Anaya y Serrano. Resultados: Se evaluaron 35 cierres de pared abdominal, 23 de ellos con calidad (65.7 %) y 12, que no fueron de calidad (34.3 %). Se observa una proporción de cierres de calidad en alumnos aprobados (f=18, 78.3%) frente a no aprobados (f= 5, 21.7%) y también en los cierres de no calidad en alumnos aprobados (f=8, 66.7%) frente a no aprobados (f=4, 33.3%). Conclusión: Los cierres de pared abdominal no exitosos en modelos murinos no se relacionan con las calificaciones reprobatorias, sin embargo, se cumplió el objetivo por el cual deseábamos evaluar dicha destreza de manera cuantitativa.
