Abstract
Con la diseminación del Internet han cambiado las formas tradicionales de transmisión y adquisición del conocimiento en todas sus ramas; y la medicina, como una disciplina de constantes cambios, no ha sido ajena a esta tecnología.Tras el advenimiento de la informática, las ciencias biológicas y médicas han encontrado un medio eficiente para la globalización del conocimiento, lo cual ha mejorado el entrenamiento y la actualización de los estudiantes y profesionales de la medicina, y ha creado la necesidad de aumentar la eficiencia de estos medios de comunicación. Con el objetivo de facilitar el acceso a la información científica a través de medios informáticos han sido desarrolladas plataformas encargadas de recopilar la información en forma de bases de datos, las cuales pueden ser consultadas a través de otra tecnología emergente como los son los motores de búsqueda. Debido a que cada sitio Web tiene características específicas que le confieren ciertas fortalezas y debilidades, tanto el estudiante como el profesional médico deben reconocerlas, para así obtener el mayor provecho de su utilización. Palabras claves: Bases de datos, motores de búsqueda, índices temáticos, infor- mación biomédica. Dissemination of Internet has changed traditional ways to transmit and acquire knowledge in every division; medicine, as a signature of constant challenges has not been isolated from this technology.After advent of informatics, biological and medical sciences have found an efficient way for knowledge globalization. This has improved the training and actualization of medical students and physicians; creating the urge to raise the efficiency of these channels of com- munication. With the aim to facilitate the access to scientific information through informatics ways, platforms have been developed to compile the information in form of databases, which can be access through other emerging technology such as search engines. Each web site has specific characteristics with strengths and weaknesses associated to them; medical students as well as physicians must be aware of this fact to properly take advantage of their use. Key words: Databases, search engines, indexes, biomedical information.
