Severe sepsis and septic shock are relatively common problems in intensive care. The mortality in septic shock is still high, and the main causes of death are multiple organ failure and refractory hypotension. Impaired tissue perfusion due to hypovolemia, disturbed vasoregulation and myocardial dysfunction contribute to the multiple organ dysfunction. Treatment of hemodynamics in septic shock consists of appropriate fluid therapy guided by invasive monitoring combined with vasoactive drugs aiming to correct hypotension and inappropriately low cardiac output. The drug of choice for low vascular resistance is norepinephrine, while insufficient myocardial contractility is commonly treated with dobutamine. The use of norepinephrine seems to be associated with better prognosis as compared to results from the use of dopamine or epinephrine. In septic shock, vasopressin levels are low, and therefore, vasopressin has been advocated as a vasopressor. Its effectiveness and safety have not yet been documented, and so far it is regarded as an experimental treatment Recent data support the use of corticosteroid, at least in some of the patients with septic shock. Also, activated protein C, a drug with anti-inflammatory and antithrombotic properties, decreases mortality in patients with septic shock.

Severe sepsis and septic shock have been part of intensivists' major challenges since the birth of the specialty. This clinical picture is followed by the development of a multiple organ failure syndrome. Our working hypothesis today is that multiple organ failures develop due to a systemic intravascular malignant inflammatory response. This article proposes an alternative understanding of the problem based on some of the recent data and understandings of non glycemic, non insulinemic endocrine dysfunction in severe sepsis and septic shock. Our presentation of selected literature supports the presence of a decreased production and activity in steroids, thyroid hormones, growth hormone, vasopressin and prolactin in septic shock. These hormones have important and synergistic functions. The disruption of which can lead to multiple organ failure in septic shock. Developing research focusing on the broad hypothalamic and pituitary functions could improve our understanding of metabolic derangements in severe sepsis and septic shock and thus provide new therapeutic options. These new therapies based on hormonal replacement are currently available at low cost and could improve outcomes.

Severe sepsis provokes significant abnormalities in host neuroendocrine system, and they are hallmarked by the glucocorticoid and growth hormone resistance, vasopressin deficiency, and compromised vagal activity. As a consequence, the increased stress hormones result in a hyperdynamic circulation, hypermetabolic state, and the hyperglycemia/insulin resistance in sepsis. The cardiac autonomic dysfunction also occurs as a consequence of depressed vagal activity. Current therapeutic strategies include insulin therapy to control hyperglycemia, physiologic doses of corticosteroids to improve immunity, growth hormone to reverse negative nitrogen balance, and vasopressin to raise blood pressure. Non-specific beta-adrenergic blockade has also been attempted to either attenuate the hypermetabolism or to reduce the inflammatory response. Future therapy may be directed at both central and peripheral immune system so as to alleviate the hyperdynamic inflammatory state and possibly encephalopathy in severe sepsis.

Severe sepsis and septic shock remains the most urgent problem. In severe sepsis and septic shock should be early goal-directed resuscitation of the septic patient during the first 6 hrs after recognition; -appropriate diagnostic studies to ascertain causative organisms before starting antibiotics; -early administration of broad-spectrum antibiotic therapy; -reassessment of antibiotic therapy with microbiology and clinical data to narrow coverage, when appropriate; -a usual 7-10 days of antibiotic therapy guided by clinical response; -source control with attention to the method that balances risks and benefits; -equivalence of crystalloid and colloid resuscitation; aggressive fluid challenge to restore mean circulating filling pressure; -vasopressor preference for norepinephrine and dopamine; -cautious use of vasopressin pending further studies; -avoiding low-dose dopamine administration for renal protection; consideration of dobutamine inotropic therapy in some clinical situations; -stress-dose steroid therapy for septic shock; use of recombinant activated protein C in patients with severe sepsis and high risk for death; -with resolution of tissue hypoperfusion and in the absence of coronary artery disease or acute hemorrhage, targeting a hemoglobin of 7-9 g/dL; -a low tidal volume and limitation of inspiratory plateau pressure strategy for acute lung injury and acute respiratory distress syndrome; -application of a minimal amount of positive end-expiratory pressure in acute lung injury/acute respiratory distress syndrome; -protocols for weaning and sedation, using either intermittent bolus sedation or continuous infusion sedation with daily interruptions/lightening; -avoidance of neuromuscular blockers, if at all possible; -maintenance of blood glucose <150 mg/dL after initial stabilization.

Severe sepsis is a major cause of mortality among critically ill patients. Early recognition accompanied by early initiation of broad-spectrum antibiotics with source control and fluid resuscitation improves outcomes. Hemodynamic resuscitation starts with fluid therapy followed by vasopressors if necessary. Cases refractory to first-line vasopressors (norepinephrine) will require second-line vasopressors (epinephrine or vasopressin) and low-dose steroid therapy. Resuscitation goals should include optimization of central venous oxygenation and serum lactate.
