Management of critically ill patients regularly involves the treatment of water and electrolyte disturbances. Moreover, critical care itself may contribute to volume overload and electrolyte abnormalities. ⋯ The shift of volume and potassium in severe pancreatitis, for example, may lead to a life-threatening situation. In brain-dead patients, successful organ donation is facilitated by careful maintenance of water and electrolyte homeostasis.

Urinary tract infection (UTI) is the most common infection in hospitalized adults. Nosocomial UTIs are mainly associated with the use of urinary catheters. Thus, the decision for catheterization should be made carefully and catheters removed in time. ⋯ Chinolones, broad-spectrum penicillins and third-generation cephalosporins are the mainstay of therapy. Comorbidities should be considered and potential obstructions of urinary flow removed. Economically important are the normally higher prices of i.v. antibiotics compared to oral use.
