INTRODUCCIÓN. El ultrasonido es fundamental en la medicina de emergencias, no se conoce cual debería ser la curva de aprendizaje para obtener las competencias técnicas y operativas; ACEP recomienda por cada ventana ecográfica realizar 25 repeticiones. No existe una curva de aprendizaje para ventana de VCI en la población de residentes colombianos. OBJETIVO: Determinar la curva de aprendizaje necesaria para obtener una proporción mayor al 80% de éxitos en la toma de la ventana ecográfica de la VCI, usando la escala de calificación para el aseguramiento de la calidad sugerida por ACEP, en residentes de I a III año de medicina de emergencias. METODOLOGÍA: Estudio experimental no comparativo, que evaluó la proporción de éxito en función del las tomas repetidas de la VCI por ultrasonido, mediciones que se tomaron luego de participar en una capacitación teórica y demostrativa de la técnica propuesta; se calificaron los videos según la escala publicada por ACEP. El análisis estadístico se realizó con un modelo logístico multinivel para la proporción del éxito, agrupado por repetición y agrupado por sujeto. RESULTADOS: Se obtuvo información de 8 residentes, cada uno realizo 25 repeticiones a 3 modelos sanos con asignación aleatoria. Se realizó la curva de aprendizaje obteniendo en 11 repeticiones una proporción de 0.80 (rango 0.54 a 0.92) y en 21 repeticiones una proporción de 0.9 (rango 0.75 a 0.96), datos ajustados por numero de repetición y residente. CONCLUSIÓN: La curva de aprendizaje para la ventana ecográfica de la VCI es de 11 y 21 repeticiones para obtener el 80% y 90% de éxito en residentes de medicina de emergencias de I a III año de la universidad del rosario.

INTRODUCTION. Ultrasound is essential in emergency medicine. However, learning curve to obtain technical and operative is unknown. ACEP suggests a minimum of 25 repeats by every ultrasound window. This study evaluated learning curve for ultrasound window of Inferior Vena Cava (IVC). AIM: To establish learning curve in emergencies medical residents needed to obtain a proportion of success above 80% in ultrasound window for IVC, measured by ACEP scale for quality assurance. METHODS: An experimental non-comparative study was designed to evaluate the success proportion of IVC ultrasound window after repetitive attempts. An expositive class of the technique was made prior to the experiment. Videos were assessed based on ACEP scales. For statistical analysis a multilevel logistic model was used for success proportion grouped by data and subject. RESULTS: Data were obtained from 8 residents. Each one made 25 repeats to 3 randomized healthy models. Learning curve adjusted by subject and number of repeats showed a proportion of 0.81 (range from 0.57 to 0.93) after 11 repeats and 0.9 (0.75 to 0.96) after 21 repeats. CONCLUSION: For a success proportion of 80 and 90% in IVC ultrasound window, 11 and 21 repeats are needed, respectively.
