The critical care of the severely injured patient--II. Pulmonary and renal support

The management of pulmonary support in trauma patients is a balance of risk versus benefit. Decisions must be based upon the patient's physiologic needs, with constant attention to the potential complications of the therapy. The avoidance of renal failure by volume replacement, careful attention to the use of potentially nephrotoxic agents, and close monitoring of renal function can reduce the incidence and severity of this serious complication of trauma. If renal failure does occur, aggressive renal replacement therapy with either intermittent hemodialysis or CRRT should be tailored to the clinical situation.
