Since its introduction in clinical use more than ten years ago, propofol is well appreciated for sedation and supplemental hypnosis in anaesthesia. However the substance is approved only for anaesthesia in children elder than three years. As can be substantiated by many data reported in literature, there are no pharmacokinetic or pharmacodynamic reasons whatsoever to withhold propofol from the younger children; this applies both to the use as a narcotic supplement and as a short term hypnotic for diagnostic and therapeutic interventions.

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. ⋯ 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.
