AbstractShock states are the leading causes of intensive care admission and are nowadays associated with high morbidity and mortality. They are driven by a complex physiopathology and most frequently a multifactorial mechanism. They can be separated in whether a decrease of oxygen delivery (quantitative shock) or an abnormal cell distribution of cardiac output (distributive shock). Septic, cardiogenic and hypovolemic shocks represent more than 80% of shock etiologies. Clinical presentation is mostly characterized by frequent arterial hypotension and sign of poor clinical perfusion. Hyperlactatemia occurs in most of shock states. The diagnostic of shock or earlier reversible "pre-shock" states is urgent in order to initiate adequate therapy. Therefore, orientation and therapies must be discussed with intensive care physiologists in a multidisciplinary approach. Etiologic investigation and correction is a primary concern. Hemodynamic and respiratory support reflect another part of initial therapy toward normalization of cell oxygenation. Fluid resuscitation is the corner stone part of initial therapy of any form of shock. Vasoconstrictive drugs or inotropic support still often remain necessary. The primary goal of initial resuscitation should be not only to restore blood arterial pressure but also to improve clinical perfusion markers. On the biological side, decrease of lactate concentration is associated with better outcome.Copyright © 2019 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier Masson SAS.
