[Clinical management of patients with sepsis].

Sepsis and septic shock are the leading causes of death in non-cardiological intensive care units in developed countries despite recent advances in critical care medicine. Sepsis is the systemic inflammatory response to infection, often associated with hypoperfusion followed by tissue injury and organ failure. Activation of monocytes/macrophages and neutrophils with consecutive release of proinflammatory mediators and activation of the coagulation cascade, seem to play a key role in the pathogenesis of sepsis. Elimination of the septic focus,antimicrobial therapy and supportive treatment are the cornerstones of sepsis therapy. Adequate and rapid volume replacement and if necessary application of catecholamines are of highest priority to optimize tissue perfusion. Norepinephrine is the vasopressor of choice and dobutamine the preferred inotropic agent. Most experts recommend hemoglobin levels of 8-10 g/dl in severe sepsis. In addition,lung protective ventilatory strategies as well as enteral and parenteral nutrition are part of the clinical management of septic patients. In mechanically ventilated patients intensive insulin therapy to maintain blood glucose at a level between 80 and 110 mg/dl has significantly reduced mortality.Furthermore,prophylaxis of deep vein thrombosis and of stress ulcer bleeding are individually applied to septic patients. Treatment of septic patients with anti-mediator strategies or high dose AT III were not successful so far. In contrast,now two new promising treatment options may be emerging: application of small doses hydrocortisone and activated protein C [drotrecogin alfa (activated)]. Large and in part multicentric studies especially in the last 2 years now allow the practicing clinician to perform a partially evidence-based management of patients with sepsis. In addition, for the first time two options for specific therapy of sepsis,application of small doses hydrocortisone and activated protein C [drotrecogin alfa (activated)],are available which may further improve prognosis for septic patients.
