There was no comparison group because the efficacy of premedication has been clearly demonstrated in the world literature, and we did not think it was ethical to deprive the patients of its benefits, because our main objective was to provide objective proof of the usefulness of an experience based practice.
No se contó con un grupo de comparación, primero porque en la literatura mundial está ampliamente demostrada la utilidad de la premedicación y no nos pareció ético privar a un grupo de pacientes del beneficio de esta, y segundo, porque nuestra meta principal era demostrar objetivamente la utilidad de una práctica que ha estado basada en la experiencia.
