The supine position is still the most frequently used type of positioning during surgical procedures. Positions other than the supine position lead to physiological alterations that have a relevant influence on the course of anesthesia and surgery. As a matter of principle, hemodynamic stability is at risk because venous blood is pooled in the lower positioned body parts. ⋯ The pathophysiological intraoperative changes caused by Trendelenburg positioning are described and approaches suitable for risk reduction are discussed. The prone position and lateral decubitus position have little influence on the intraoperative homeostasis. Nevertheless, there is an ongoing discussion concerning the efficacy of a 15° left lateral position during caesarean section, which is also discussed in a separate section of this review.

Extracorporeal membrane oxygenation (ECMO) is becoming more and more clinically important. The extracorporeal circuit for membrane oxygenation consists of a pump, a membrane oxygenator and large volume tubing. ⋯ As a consequence, the pharmacokinetic-pharmacodynamic (pk-pd) target parameters cannot be achieved. The selection of an appropriate substance and the mode of application, combined with therapeutic drug monitoring (TDM), can significantly improve the therapeutic outcome of critically ill patients.

[Regional anesthesia in daily clinical practice: an economic analysis based on case vignettes].
The economic effect is a crucial aspect of every medical procedure. This article analyzes the economic implications of various methods in anesthesia based on three case vignettes. ⋯ Even considering that this cost analysis was calculated based on data from only one medical institution (General Hospital of Vienna, Medical University of Vienna), regional anesthesia appeared to be cost efficient compared with other anesthesia procedures. Main cost drivers in this example were personnel costs.
