[Knowledge gained from a 31-h power outage in Berlin Köpenick-medical problems and challenges].
On 19 February 2019 the severance of a 110kW cable caused an extensive electrical power cut in the Treptow-Köpenick district of Berlin. Subsequently, ca. 30,000 households were without electricity and ca. 70,000 people were affected. The power cut lasted more than 24h and all those involved were faced with a multitude of challenges. ⋯ During the procedure it was necessary to evacuate an intensive care ward or intermediate care ward with 23 patients due to the loss of power supply in the affected area. Hospitals must be prepared for such scenarios within the framework of preliminary planning. Furthermore, preliminary planning containing the special needs of vulnerable groups must be carried out on the part of the responsible authorities.

The use of tranexamic acid (TXA) is established in the treatment of bleeding, especially of bleeding due to hyperfibrinolysis. In recent years the prophylactic use of TXA in trauma and orthopedic surgery has increased leading to open questions regarding potentially associated risks and a possible classification as off label use. The available literature provides a sound basis for the recommendation that TXA can be used in these indications provided that an individual risk assessment is done in patients with increased risks for thromboembolic complications. Although the prophylactic use of TXA in orthopedic surgery and trauma is not explicitly listed in the product characteristics, it should not be regarded as an off label use.

Patient-controlled intravenous analgesia (PCIA) is a well-established technique in acute pain management and available in most German hospitals. Despite its widespread use, information on current clinical practice is limited. This investigation evaluated clinical practice and monitoring as well as PCIA-associated adverse events and critical incidents in German hospitals. ⋯ PCIA is a frequently used analgesic technique in German hospitals. There were many differences in how PCIA therapy was applied and monitored on general wards. Adverse events occurred to a significant extent, with a considerable part of them, which might be preventable. Critical incidents were perceived more often when standards for monitoring on general wards were higher. Consented current recommendations regarding treatment and monitoring standards as well as the systematic recording of complications when using PCIA are pending.

The electroencephalogram (EEG) is increasingly being used in the clinical routine of anesthesia in German-speaking countries. In over 90% of patients the frontal EEG changes somewhat predictably in response to administration of the normally used anesthetic agents (propofol and volatile gasses). ⋯ This article explains the clinical interpretation of the most important EEG patterns and the biophysical background. Also discussed are important limitations and pitfalls for the clinical routine, which the anesthetist should know in order to utilize the EEG as an admittedly incomplete but clinically extremely important parameter for the level of consciousness.
