Electroconvulsive therapy is a well-established form of treatment for a broad spectrum of severe psychiatric disorders. The treatment, in which a generalized epileptic seizure is provoked by electrical stimulation of the brain, is performed with the patient under anesthesia and muscle relaxation. Therefore, sufficient knowledge of the physiological and pharmacological characteristics is an essential requirement for safe anesthesia. The following review is intended to provide some new aspects of the procedure and management of anesthesia.

Each weekend soccer arenas attract hundreds of thousands of spectators with the German Bundesliga being one of the most attractive sport series worldwide. In 2006 when the FIFA soccer World Cup™ took place in Germany, the precautions in the participating arenas against mass casualty incidents (MCI) reached a level formerly unknown in Germany. However, it is unknown how soccer arenas are prepared to deal with such incidents in everyday life. ⋯ Most of the participating arenas were adequately staffed to manage the first phase of MCIs but in contrast command structures and transport capacities often focused on individual emergencies. Although most of the participants stated that they planned the resources provision according to well established algorithms, the resources actually available at the arenas varied considerably. The frequency of MCIs in soccer arenas was surprisingly high in contrast to the frequency of MCI-related drills.

An update of the international guidelines for therapy of sepsis was published in February 2012 by the Surviving Sepsis Campaign (SSC). The update includes a further development of the guidelines from 2004 and 2008. The guidelines are divided into three sections, sepsis-specific therapeutic measures, recommendations on general intensive care measures for sepsis and finally special features of sepsis in pediatric intensive care medicine are presented in detail. This article discusses the most important amendments in the first two sections and delving deeper into the guidelines.

Transfusion-related acute lung injury (TRALI) developed into the leading cause of transfusion-related morbidity and mortality after the first description by Popovsky et al. approximately three decades ago. It was the most frequent reason for transfusion-related fatalities worldwide before implementation of risk minimization strategies by donor selection. Plasma-rich blood products, such as fresh frozen plasma and apheresis platelets seem to be the leading triggers of TRALI. ⋯ Neutrophils are primed by the underlying condition, e.g. sepsis or trauma during the first event and these primed neutrophils are activated by transfused leukoagglutinating antibodies (immunogen) or bioreactive mediators (non-immunogen) during the second-event. Transfusion of leukoagglutinating antibodies from female donors with one or more previous pregnancies is the most frequent reason. No more TRALI fatalities were reported after implementation of the donor selection in Germany in 2009.

Electrolyte disorders are common and potentially fatal laboratory findings in emergency patients. Approximately 20 % of patients in the emergency department present with either hyponatremia or hypernatremia. Recently it was shown that disorders of serum sodium are not only an expression of the severity of the underlying disease but independent predictors for the outcome of patients. ⋯ A close monitoring of serum sodium concentration is, however, essential in any case of correction of hyponatremia or hypernatremia in order to avoid rapid overcorrection and subsequent complications. A profound knowledge of the mechanisms underlying the development of hyponatremia, e.g. diuretics, syndrome of inappropriate antidiuretic hormone secretion (SIADH), heart failure and cirrhosis of the liver and hypernatremia, e.g. dehydration, infusions, diuretics and osmotic diuresis is essential. The present article describes the epidemiology, etiology and correction of hyponatremia and hypernatremia on the basis of current knowledge with special emphasis on emergency department patients.
