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.

Clinical Trial
[Plasma concentrations of bupivacaine for continuous peridural anesthesia in children].
Epidural anaesthesia is extremely useful in providing postoperative analgesia for children after surgery of the lower body. Although results on early pharmacokinetics in children have previously been reported, no data are available on the long-term effects of epidural anaesthesia. The aim of this investigation was the assessment of plasma bupivacaine levels in children with continuous epidural anaesthesia in the postoperative period. ⋯ There were no neurologic complications or signs of local anesthetic intoxication. In conclusion our results show that a dose of up to 0.4 mg/kg/h bupivacaine during continuous epidural infusion is not associated with toxic complications. Careful monitoring of the children by experienced staff is mandatory.
