When septic shock is suspected, the priority is to stabilize circulation quickly while beginning antimicrobial therapy. The body's response to severe infection causes widespread vasodilation and fluid leakage from vessels, which drop blood pressure and impair organ perfusion. The first move is aggressive IV fluid resuscitation with balanced crystalloids to restore intravascular volume and improve tissue perfusion. At the same time, start broad-spectrum antibiotics promptly to control the infection and reduce the bacterial load, since delays worsen outcomes. If feasible, obtain cultures before antibiotics, but do not delay treatment for results. Giving diuretics would remove more fluid from the circulation and worsen hypotension, making the situation worse. Delaying antibiotics until after culture results is not appropriate because time is critical in septic shock.
