Combination of problem-based learning with high-fidelity simulation in CPR training improves short and long-term CPR skills: a randomised single blinded trial
Performance of sufficient cardiopulmonary resuscitation (CPR) by medical personnel is critical to improve outcomes during cardiac arrest. It has however been shown that even health care professionals possess a lack of knowledge and skills in CPR performance. The optimal method for teaching CPR remains unclear, and data that compares traditional CPR instructional methods with newer modalities of CPR instruction are needed. We therefore conducted a single blinded, randomised study involving medical students in order to evaluate the short- and long-term effects of a classical CPR education compared with a bilateral approach to CPR training, consisting of problem-based learning (PBL) plus high fidelity simulation. One hundred twelve medical students were randomized during a curricular anaesthesiology course to a control (n = 54) and an intervention (n = 58) group. All participants were blinded to group assignment and partook in a 30-min-lecture on CPR basics. Subsequently, the control group participated in a 90-min tutor-guided CPR hands-on-training. The intervention group took part in a 45-min theoretical PBL module followed by 45 min of high fidelity simulated CPR training. The rate of participants recognizing clinical cardiac arrest followed by sufficiently performed CPR was the primary outcome parameter of this study. CPR performance was evaluated after the intervention. In addition, a follow-up evaluation was conducted after 6 months. 51.9% of the intervention group met the criteria of sufficiently performed CPR as compared to only 12.5% in the control group on the day of the intervention (p = 0.007). Hands-off-time as a marker for CPR continuity was significantly less in the intervention group (24.0%) as compared to the control group (28.3%, p = 0.007, Hedges’ g = 1.55). At the six-month follow-up, hands-off-time was still significantly lower in the intervention group (23.7% vs. control group: 31.0%, p = 0.006, Hedges’ g = 1.88) but no significant difference in sufficiently performed CPR was detected (intervention group: 71.4% vs. control group: 54.5%, p = 0.55). PBL combined with high fidelity simulation training leads to a measurable short-term increase in initiating sufficient CPR by medical students immediately after training as compared to classical education. At six month post instruction, these differences remained only partially.

Neue Weiterbildung Intensivmedizin: Bewährtes Konzept mit neuen kompetenzbasierten Inhalten
Die Intensivmedizin ist ein sehr komplexer Bereich in der modernen Medizin, welcher ohne jeden Zweifel eine spezielle Weiterbildung auf der Basis der verschiedenen Facharztqualifikationen erfordert. Kritisch kranke Patienten benötigen nicht nur eine kontinuierliche 24-stündige Betreuung durch einen Arzt, sondern durch einen Arzt, der den besonderen Herausforderungen gewachsen ist. Deswegen wurde in den 2013 publizierten überarbeiteten Qualitätsindikatoren Intensivmedizin aufgenommen, dass zumindest in der Kernarbeitszeit ein Facharzt mit Zusatzqualifikation Intensivmedizin auf der Intensivstation präsent sein muss [1]. Die Grundlagen der ärztlichen Weiterbildung werden auf europäischer Ebene in der UEMS (Union Européenne des Médicins Spécialistes – Vereinigung der Europäischen Medizinischen Fachgesellschaften) geregelt, in der alle medizinischen Fachdisziplinen repräsentiert sind. Für die Intensivmedizin als interdisziplinäres Fachgebiet wurde 1999 im Rahmen der UEMS ein interdisziplinäres Komitee gegründet, das „Multidisciplinary Joint Committee of Intensive Care Medicine (MJCICM)“, welches sich seitdem mit den speziellen Anforderungen in dem komplexen Bereich beschäftigt [2] [3].

Fluid therapy in patients with brain injury: what does physiology tell us?
The unique component of the cerebral circulation is the so called blood-brain barrier (BBB). The anatomical structures of the BBB consist of the cerebral vascular endothelial cells, the surrounding pericytes, the basal lamina and the perivascular astrocytes. These form the so-called neurovascular unit. Notably, the endothelial cells are interconnected by tight junctions; thus, any solute transport will be transcellular, as opposed to paracellular, in the peripheral circulation. The specific anatomy of the neurovascular unit allows the brain volume to be kept constant even in the context of marked changes in intravascular volume status.

Laienreanimation - Alles ist besser, als nichts zu tun
Bereits 3–5 min nach einem Herz-Kreislauf-Stillstand treten unwiderrufliche Schäden des Gehirns auf. Minuten, die über ein Menschenleben entscheiden können. Obwohl der Herz-Kreislauf-Stillstand in ca. 60 % der Fälle beobachtet wird, beginnen in Deutschland weniger als 18 % der Umstehenden mit Wiederbelebungsmaßnahmen und übernehmen damit mechanisch die Funktion des Herzens, das den Körper und damit das Gehirn mit Sauerstoff versorgt. Da der professionelle Rettungsdienst zwar schnell, jedoch nahezu nie innerhalb von 5 min beim Patienten sein kann, ist man in genau diesen entscheidenden Minuten auf die Maßnahmen der Ersthelfer angewiesen.

Re-evaluating currently available data and suggestions for planning randomised controlled studies regarding the use of hydroxyethyl starch in critically ill patients - a multidisciplinary statement
Introduction: Hydroxyethyl starch (HES) is a commonly used colloid in critically ill patients. However, its safety has been questioned in recent studies and meta-analyses. Methods: We re-evaluated prospective randomised controlled trials (RCT) from four meta-analyses published in 2013 that compared the effect of HES with crystalloids in critically ill patients, focusing on the adherence to 'presumably correct indication'. Regarding the definition of 'presumably correct indication', studies were checked for the following six criteria (maximum six points): short time interval from shock to randomisation (<6 h), restricted use for initial volume resuscitation, use of any consistent algorithm for haemodynamic stabilisation, reproducible indicators of hypovolaemia, maximum dose of HES, and exclusion of patients with pre-existing renal failure or renal replacement therapy. Results: Duration of fluid administration ranged from 90 min up to a maximum of 90 days. Four studies considered follow-up until 90-day mortality, three studies 28-/30-day mortality, whereas four studies reported only early mortality. Included studies showed a large heterogeneity of the indication score ranging between 1 and 4 points with a median (25%; 75% quartile) of 4 (2; 4). Conclusions: The most important question, whether or not HES may be harmful when it is limited to immediate haemodynamic stabilisation, cannot be answered yet in the absence of any study sufficiently addressing this question. In order to overcome the limitations of most of the previous studies, we now suggest an algorithm emphasising the strict indication of HES. Additionally, we give a list of suggestions that should be adequately considered in any prospective RCT in the field of acute volume resuscitation in critically ill patients.

Erste Hilfe und Traumamanagement – Von todernster Spielerei zu evidenzbasierter Professionalität
In Deutschland werden pro Jahr ca. 35 000 Polytraumapatienten durch den Rettungsdienst versorgt, fast 15 % dieser Patienten versterben. Damit muss bei den unter 40-Jährigen das Polytrauma als Todesursache Nummer eins gelten. Die gesellschaftliche und menschliche Relevanz dieses Themas kann also nicht infrage gestellt werden. Selbstverständlich erwächst daher die Forderung, dass medizinische Versorgung der Patienten auf evidenzbasierten Füßen stehen muss. Das klingt trivial, aber sogar die Literatur propagiert oft tradierte Dogmen wie z. B. das Statement, dass die Wiederbelebung eines Traumapatienten bei Herz-Kreislauf-Stillstand nicht sinnvoll ist und daher unterbleiben sollte.
