Miguel Romano, MD; Eduardo Viana, MS; José Diogo Martins, MD; Rogério Corga da Silva, MD – Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection with a high mortality rate. Septic shock is a subset of sepsis with manifest circulatory dysfunction (use of vasopressors and persistent elevation of lactic acid) . As stated in literature, in addition to the use of empiric antibiotics and control of the infectious focus, intravenous fluid therapy is an essential intervention to promote hemodynamic stabilization. However, the literature also describes harmful outcomes related to fluid overload.
