None of the currently available inhaled anesthetics has all of the properties of an "ideal" inhaled agent. The exceptionally low solubility of desflurane and sevoflurane offers a significantly greater precision of control over maintenance of anesthesia and a potential for a more rapid recovery from anesthesia than other inhaled anesthetics. Sevoflurane appears to offer some advantages regarding cardiovascular stability. ⋯ Renal toxicity is discussed for enflurane and sevoflurane. Breakdown products of volatile agents with carbon dioxide absorbents have to be mentioned especially for sevoflurane (compound A) and desflurane (CO). In contrast to intravenous anesthetics, volatile anesthetics are associated with cardio- and cerebroprotection.

After various observational studies demonstrated a benefit of extracorporeal membrane oxygenation (ECMO) in the therapy of severe acute respiratory distress syndrome (ARDS), ECMO now represents an important contribution for ARDS therapy using clinical algorithms despite a lack of positive controlled studies. In specialized centers patients with severe ARDS and imminent hypoxia despite intensive conventional therapy, are treated with ECMO using blood pumps and artificial membrane lungs (oxygenators) for extracorporeal lung assist. ⋯ New oxygenators with significantly decreased blood resistance allow the clinical application of pumpless arteriovenous extracorporeal lung assist (ECLA). After these new developments indications for ECMO could be extended from use not only as ultimate ratio but to less severe ARDS to enable lung protective, less invasive mechanical ventilation.

Levosimendan is a recently developed drug which is not yet approved for clinical routine use in Germany. The clinical use is limited to a few selected cases and it has been used as a salvage therapy in patients with severe heart insufficiency. ⋯ However, in some European countries levosimendan is used in clinical routine situations and the European Society of Cardiologists has included the drug in their guidelines for treatment of acute heart failure. The following article describes the main pharmacological characteristics of levosimendan and summarises the indications for this new drug for physicians working in the field of anaesthesia or intensive care.

Human factors (HF) play a major role in crisis development and management and simulator training can help to train HF aspects. We developed a modular training concept with psychological intensive briefing. The aim of the study was to see whether learning and transfer in the treatment group (TG) with the module "communication and team-cooperation" differed from that in the control group (CG) without psychological briefing ("anaesthesia crisis resource management type course"). ⋯ A training concept with psychological intensive briefing may enhance the transfer of HF aspects more than classical ACRM.
