The required fuid volume difers among patients with septic shock. Enterocyte injury caused by shock may increase the need for fuid by triggering a systematic infammatory response or an ischemia-reperfusion injury in the presence of intestinal ischemia/necrosis. This study aimed to evaluate the association between enterocyte injury and positive fuid balance in patients with septic shock.
