    Abstract:
    The management of critically ill patients often requires an advanced hemodynamic monitoring. Beside pulmonary artery catheter (PAC) and transesophageal echocardiography (TEE) the transpulmonary indicator dilution technique (TPID) with arterial registration of the indicator dilution curves is a possible approach to get additional hemodynamic information. Being less invasive, measurements of cardiac output by transpulmonary thermodilution are as reliable as the thermodilution using a PAC. Transpulmonary thermodilution can be used even in small children. In addition, intrathoracic blood volume (ITBV) and extravascular lung water (EVLW) can be estimated. ITBV seems to be a better surrogate of cardiac filling than central venous pressure and pulmonary capillary wedge pressure. EVLW can be of special value in the fluid-management of patients with systemic inflammatory response syndrome or acute respiratory failure. By using the dye indocyanine green (ICG) as a second indicator TPID can be performed as transpulmonary double indicator dilution technique. The resulting thermodilution and dye curves are measured with a combined fiberoptic-thermistor catheter. This allows the more accurate measurement of ITBV and EVLW and in addition the assessment of total circulating blood volume and ICG-clearance. ICG-clearance serves clinically as a rapidly reacting indirect measure of liver function. As with the other methods of advanced hemodynamic monitoring the data available at present do not show a positive effect on the incidence of organ failure and mortality by monitoring critically ill patients with TPID. Before applying an advanced hemodynamic monitoring it should be asked critically which parameter is needed for the therapy-management of the individual patient. Based on this a differentiated monitoring decision has to be made.
