[Patients in circulatory shock in emergency and intensive care units].
Patients in circulatory shock are being treated in emergency as well as in intensive care units. Despite different resources in personnel and technical equipment in both areas, patient management has to follow standardized protocols. Diagnosis of shock has to be based upon objective parameters (lactate, pH, standard bicarbonate, arterial blood pressure, central venous pressure, cardiac output). Aim of shock treatment is restoration of adequate tissue perfusion with the use of fluid and red blood cell replacement, vasoconstrictors, inotropics, substances improving microcirculation, and mechanical circulatory support. Target values are: mean arterial blood pressure >80 mmHg, central venous pressure >6 mmHg, hemoglobin >8.0 g/dl, cardiac index >3.5 l/min/m(2). New concepts for optimization of hemodynamics and hematocrit, cortisone, intraaortic balloon counterpulsation, mechanical ventilation with low tidal volumes, and intensive insulin therapy are discussed. However, as shock reversal is dependent on its reason, clarification and treatment of the shock causing event has to be performed with highest priority.
