In this article, a clinical case will be presented, emphasizing the evolution of the disease, initial and subsequent management during hospitalization, together with an update based on the literature, on the treatment of this pathology, in order to propose preventive interventions or protocols that allow avoiding hospitalizations and unnecessary treatments.
