Overview
Early and appropriate antibacterial therapy is a principal intervention in septic patients. Adequate fluid resuscitation in the hyperdynamic stage of sepsis increases renal perfusion and via increased capillary permeability leads to a leak into the third space. The increased clearance and volume of distribution may result in low plasmatic concentration of antimicrobial drugs. Alternatively, sepsis can induce multiple organ dysfunction (kidney, liver), causing a decrease of antimicrobial drug clearance with increased risk of toxic effects.
To optimize antibacterial therapy, clinician must know the properties of the used antibiotics and how these may be affected by the pathophysiological changes occurring during sepsis.
