Introducción: El entrenamiento en simuladores es considerado una herramienta fundamental en las especialidades quirúrgicas, contribuyendo en el aprendizaje de una determinada técnica quirúrgica.Existen modelos de simulación sintéticos que replican la anatomía ventricular con alta fidelidad sin embargo tienen un costo elevado. Algunos centros describieron el uso de cadáveres humanos pero la disponibilidad del material suele ser limitada y la adquisición dificultosa. Otros autores utilizan entrenamiento en modelos biológicos vivos (roedores de laboratorio) que presentan la ventaja de tener alta fidelidad en cuanto a la consistencia de tejidos, sin embargo, la utilización de estos modelos se encuentra cuestionados desde el aspecto ético.Material y Métodos: Se presenta un modelo de simulación que utiliza unidades de cerebro bovino y membrana amniótica. Colocamos el cerebro bovino y las unidades de membrana amniótica dentro de un recipiente esférico de poliestireno expandido. Una vez que se forma la esfera, insertamos dos trocares que nos permitirán insertar el neuroendoscopio y llenarlo con agua.Resultado: Presentamos un nuevo modelo accesible y realista para la simulación neuroendoscópica que reproduce ejercicios de biopsia, coagulación de tejidos, fenestración y dilatación de membrana.Conclusión: Los simuladores para neuroendoscopía descritos hasta ahora son confiables, pero conllevan un alto costo. Los modelos con animales vivos, aunque con menor costo, son cuestionados desde un punto de vista ético.En el trabajo actual, describimos un modelo de simulador neuroendoscópico ventricular de alta fidelidad que, debido a su bajo costo, permite ser replicado en cualquier centro de entrenamiento que tenga un neuroendoscopio.

Neurosurgery Simulators Developed for Neurosurgical Training in Brazil: A Systematic Review

et al. 2019

View full text Add to dashboard Cite

Introduction Simulation in neurosurgery is a growing trend in medical residency programs around the world due to the concerns there are about patient safety and the advancement of surgical technology. Simulation training can improve motor skills in a safe environment before the actual setting is initiated in the operating room. The aim of this review is to identify articles that describe Brazilian simulators, their validation status and the level of evidence (LoE). Methodology This study was conducted using the Preferred Reported Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A search was performed in the Medline, Scielo, and Cochrane Library databases. The studies were evaluated according to the Medical Education Research Quality Instrument (MERSQI), and the LoE of the study was established according to the classification system of the Oxford Centre for Evidence-Based Medicine (OCEBM), which has been adapted by the European Association of Endoscopic Surgery. Results Of all the studies included in this review, seven referred to validated simulators. These 7 studies were assigned an average MERSQI score of 8.57 from 18 possible points. None of the studies was randomized or conducted in a high-fidelity environment. The best evidence was provided by the studies with the human placenta model, which received a score of 2b and a degree of recommendation of 3. Conclusion Brazilian simulators can be reproduced in the different laboratories that are available in the country. The average MERSQI score of Brazilian studies is similar to the international average score. New studies should be undertaken to seek greater validation of the simulators and carry out randomized controlled trials.
