Vigencia y complejidad del fenómeno placebo.

Abstract

After a critical analysis of the performance of the placebos and their possible mechanisms of action, the conclusions are: first, the phenomenon placebo is a prevailing event, whose role exceeds the function of device that is usually conferred to it in scientific literature. It is an event of which it is not possible to get rid, since it represents a fundamental aspect in all process of intervention; that is to say, its activity is extensive and complex subject, that does not have to be restricted to an only scope to discipline or professional, on the contrary, it happens in all the contexts. Second, and consequently, the exact explanation of the phenomenon placebo cannot be obtained by means of the aid of a single sector of the reality, on the contrary, the best approach to its understanding is, even though centered in the psychological level, of character multilevel, since its occurrence implies aspects from the biochemist to the social level.

Sin duda uno de los temas que más controversia ha desencadenado en el tiempo es aquel que se trata de abarcar mediante el término placebo. Un ejemplo excepcional de lo polémico que pueden ser los resultados de un estudio el cual incluya un grupo control placebo, es el publicado, recientemente (11 de Junio de 2002, Nº 2, Volumen 347), por J. Bruce Moseley y colaboradores en el New England Journal of Medicine. En este trabajo, 180 pacientes aquejados de osteoartritis de la rodilla fueron intervenidos quirúrgicamente. Siguiendo un diseño ciego simple, los sujetos se asignaron aleatoriamente a una de las modalidades de intervención: débridement artroscópico, lavage artroscópico, o cirugía placebo. A los pacientes en el grupo placebo se le practicaron unas incisiones en la piel, simulando la maniobra de débridement pero sin la inserción del artroscopio.
