[Dengue: a new approach].

Previous definition of classic dengue, with or without bleeding, and of dengue hemorrhagic fever (DHF) that may evolve without bleeding and with or without dengue shock syndrome (DSS) are reviewed here. The classical approach to the diagnosis and treatment of dengue, although useful in the past, nowadays breeds confusion and adds a burden to the physician's task of decision-making regarding the treatment of patients with severe forms of the disease. The classification of dengue proposed in this paper, and summarized in a diagram, incorporates new concepts about sepsis, systemic inflammatory response syndrome (SIRS), and acute respiratory distress syndrome (ARDS). This new approach, in our view, is a useful guide to initial evaluation and treatment of the disease. It also approximates the dengue syndrome to other protocols and medical procedures routinely used in intensive care units, making it easier to be followed by the health personnel working in areas subject to epidemic bursts.
