It should be stated for this discussion that 99% of the referents in the literature compare GA with classical regional anaesthesia RA combined peridural-general anaesthesia and not one controlled clinical trial was found in which the SRA technique was compared with the GA one regarding mortality.
Es importante aclarar y recalcar que, para nuestra discusión, 99% de los artículos de referencia de la literatura evalúan la anestesia general con la anestesia regional clásica, la anestesia combinada peridural-general y no hay un solo ensayo clínico controlado en la cual se compare la técnica regional selectiva con la general respecto a mortalidad.
