The incidence of postoperative cognitive dysfunction (POCD) is often underestimated and not intuitively present by many anesthetists. POCD often occurs in the elderly but is also seen in younger patients. The incidence of POCD 1 week after non-cardiac surgery covers a span between 19-41% in patients older than 18 years. ⋯ The age of the patient is one of the main risk factors for the development of POCD. Data on how to avoid POCD are limited. However, the maintenance of homoeostasis is an important cornerstone of prophylaxis.

Endotracheal intubation remains the gold standard for securing the airway in emergency medicine. However, difficult endotracheal intubation and complications are common during emergency intubation. In contrast to conventional direct laryngoscopy, the new generation of devices does not require direct visualization of the vocal cords for endotracheal tube placement. ⋯ Recent studies showed that utilization of these devices can be easily learned. The technique of indirect laryngoscopy is currently used for securing the airway in daily anesthesia routine as well as for managing the difficult airway in the operating room. This article gives an overview of available devices for indirect endotracheal intubation as well as the current literature.

Allowances have been made for surveillance as an essential component in the chain of anesthesiological care and the increasing importance of the recovery room by reformulation of the recommendations of the German Society for Anesthesiology and Intensive Care medicine (Deutsche Gesellschaft für Anästhesiologie und Intensivmedizin, DGAI) and the Professional Association of German Anesthetists (Berufsverband Deutscher Anästhesisten, BDA) on surveillance following anesthesia procedures. These recommendations replace the previous guidelines on postoperative surveillance and the recommendations on organization and equipping of recovery units. In the following article the essential new aspects of the recommendations on surveillance following anesthesia procedures will be presented.

The outcome of cardiopulmonary resuscitation (CPR) depends on the quality of chest compressions. Current European Resuscitation Council (ERC) guidelines promote the development of feedback systems. However, no studies presenting satisfactory results of feedback use have been published. ⋯ With the AED real-time feedback technology used in this study standardized performance of chest compressions could be maintained in a professional ambulance service. Implementation of a feedback system requires training of ambulance staff.

Randomized Controlled Trial
[EEG-adjusted target-controlled infusion : Propofol target concentration with different doses of remifentanil].
The aim of this study was to examine to what extent the use of electroencephalography (EEG) monitoring leads to an adaptation of the target-controlled infusion (TCI) concentration of propofol during propofol anaesthesia with different doses of remifentanil. ⋯ The study demonstrates that remifentanil has both analgetic and hypnotic effects. With increasing remifentanil dose the propofol requirement decreased and in this context EEG monitoring is useful to adapt the target concentrations of propofol to the patients' age and gender.
