The year 1938 is the year in which electroconvulsive therapy started to be used in the psychiatric field. Although it is a form of therapy with a history of nearly a century, it still remains a stigmatized therapy, largely because it is still seen nowadays as a crude and coercive method. The emergence of this form of therapy was a necessity in the treatment of patients with psychiatric pathology, due to the lack of specific medication in those times, but over the years its use has decreased, both due to the antipsychiatry trend and the diversity of psychotropic medication. Nowadays, the procedure for applying electroconvulsive therapy has improved, both by using intravenous general anesthesia with an oxygen mask and by replacing the sinus electrical stimulus with the one in the form of a short pulse, at the recommendation of professional organizations, thus increasing its efficiency. So its applicability is continued and necessary in the therapeutic management of patients with psychiatric pathology treatment resistant.
