Septic shock is a subset of sepsis in which underlying circulatory and cellular/metabolic abnormalities are profound enough to substantially cause mortality. Patients with septic shock can be identified with a clinical construct of sepsis with persisting hypotension requiring vasopressors to maintain MAP 65 mm Hg and having a serum lactate > 2 mmol/L (18 mg/dL) despite adequate volume resuscitation. With these criteria, hospital mortality is in excess of 40%. (2, 3) Adequate fluid resuscitation is one of the keystones in the management of severe sepsis. Since severe sepsis is associated with absolute or relative hypovolemia. the aims being to preserve intravascular fluid volume, restore effective tissue perfusion, and reestablish and maintain a balance between tissue oxygen demand and supply. ⁽⁴⁾ Resuscitation of circulatory failure implies volemic optimization, which targets oxygen delivery improvement. ⁽⁵⁾ Predicting fluid responsiveness in critically ill patients at bedside is a great challenge for physicians.
