Randomized Controlled Trial
[Variation in closeness to reality of standardized resuscitation scenarios : Effects on the success of cognitive learning of medical students].
Simulation often relies on a case-based learning approach and is used as a teaching tool for a variety of audiences. The knowledge transfer goes beyond the mere exchange of soft skills and practical abilities and also includes practical knowledge and decision-making behavior; however, verification of knowledge or practical skills seldom unfolds during simulations. Simulation-based learning seems to affect many learning domains and can, therefore, be considered to be multifactorial in nature. At present, studies examining the effects of learning environments with varying levels of reality on the cognitive long-term retention of students are lacking. ⋯ For simulation-based learning the outcome depends not only on knowledge, practical skills and motivational variables but also on the onset of negative emotions, perception of own ability and personality profile. Simulation training alone does not appear to guarantee learning success but it seems to be necessary to establish a simulation setting suitable for the education level, needs and personality characteristics of the students.

In addition to specific treatment of the underlying cause, the therapy of acute respiratory distress syndrome (ARDS) consists of lung protective ventilation and a range of adjuvant and supportive measures. ⋯ Lung protective ventilation with reduced tidal volumes as well as inspiratory pressures represents the current standard of care and was utilized in all network centers. Prone positioning was widely used. Promising adjuvant therapies such as the muscle relaxation during the early phase of the ARDS, fluid restriction and corticosteroids were used less frequently. During ECMO respirator therapy was generally continued with ultraprotective ventilator settings.

Many missions in the preclinical emergency services seem to be triggered by false indications as defined by the Federal State Rescue Act. These emergency calls are often a result of or associated with social issues. Emergency rescue personnel are confronted with social problems and as a result often feel left alone with the problem. ⋯ Emergency personnel have only limited options for dealing with such problems; however, it is important to be aware of regional structures and non-medical organizations, which might be of help in such situations. These include social services, youth welfare services, crisis interventions teams and social psychiatric services.

Randomized Controlled Trial Comparative Study
Randomized comparison of the i-gel(TM) with the LMA Supreme (TM) in anesthetized adult patients.
The LMA Supreme(TM) (LMA-S) and i-gel(TM) are two of the most commonly used supraglottic airway devices (SADs) with an inbuilt drain channel. These devices are particularly indicated for performing certain procedures accompanied by high peak airway pressure, such as laparoscopy. This study compared the devices regarding efficacy, safety, ease of use and incidence of adverse events, focusing on the postoperative rate of sore throat, dysphagia or dysphonia and development with time, in patients undergoing laparoscopic cholecystectomy procedures under general anesthesia. ⋯ No differences were found between i-gel and LMA-S regarding leak pressure in the groups of anesthetized patients undergoing laparoscopic cholecystectomy. The LMA-S was easier to insert than the i-gel (based on its better first time success rate) and this device showed better ease of drain tube insertion, although the i-gel was quicker to insert than the LMA-S. The i-gel resulted in higher sore throat scores at 2 h postoperatively and lower POPD reduction during the 2 h period studied in the recovery room was reported.

Approximately 18 million patients are treated in German hospitals annually. On the basis of internationally published data the number of in-hospital cardiac arrests can be estimated as 54,000 per year. A structured treatment of in-hospital resuscitation according to the current scientific evidence is essential. ⋯ The prevention of cardiac arrest is of special importance. Uniform and low threshold criteria for alarming the medical emergency team have to be defined to be able to identify and treat critically ill patients in time before cardiac arrest occurs.
