Surgical replacement of aortic valves is the gold standard for therapy of high grade aortic valve stenosis. However, the changes in demography confront the responsible medical discipline with an increasingly higher risk profile of patients which necessitates the development of new less invasive alternative forms of treatment for the surgical therapy of aortic valve stenosis. This developmental process has progressed from mini-thoracotomy to transcatheter aortic valve implantation (TAVI). ⋯ Because TAVI can be carried out while the heart is still beating and without a sternotomy or heart-lung maschine, this procedure is particularly suitable for elderly multimorbid patients and/or patients with previous cardiac surgery. The initial results of large prospective multicenter studies underline the value of TAVI in the modern treatment of high risk patients with symptomatic aortic valve stenosis. In addition to an understanding of the surgical procedure, anesthetists must have precise knowledge of the perioperative anesthesia management and possible complications of the procedure.

Intraosseous infusion has become established as a fast and safe alternative to conventional vascular access in emergency situations. Originally the use of intraosseous access was limited to children up to 6 years of age and to adults for cardiopulmonary resuscitation but this limitation has now been removed. The aim of this study was to obtain data on mission reality regarding the use of intraosseous access in the prehospital setting against the background of the expanded recommendations on the use of the intraosseous infusion. ⋯ The expanded indication recommendations for the use of intraosseous infusion in the prehospital setting enter more and more mission reality in air rescue services in Germany.

With the demands faced by anesthetists and intensive care physicians apparently increasing continuously in Germany, the increased risk of burnout in comparison with the general working population is discussed. This debate has previously been merely speculative because of the lack of studies comparing the burn-out risk of the German working population with anesthetists. Accordingly it was not certain whether anesthetists really are at greater risk of developing burnout as has often been suggested. Moreover, age, gender, function, workplace environment, e.g. working at a hospital compared to a general practitioner (GP) surgery, may influence the risk of burnout. Therefore, this study examined whether the risk for anesthetists in Germany suffering from burnout really is greater than in other occupations. In addition, factors influencing the burnout risks of anesthetists were analyzed. ⋯ Despite 40.1% of anesthetists being at high risk of burnout, generally speaking the risk of burnout among anesthetists was not higher than in other occupational groups in Germany. However, burnout risks for specific groups, such as female junior doctors in anesthesia, were higher and the possibility of providing social support in the workplace should be considered.

Angiotensin-converting enzyme (ACE) inhibitors block the catalysis of angiotensin I to angiotensin II and also the breakdown of bradykinin. ACE inhibitor-induced angioedema is mediated by inhibited bradykinin degradation leading to enhanced bradykinin plasma levels. ⋯ A patient with acute ACE inhibitor-induced angioedema was treated with icatibant, a specific bradykinin B2 receptor antagonist approved for the treatment of hereditary angioedema. A single subcutaneous injection of 30 mg icatibant resulted in a rapid onset of symptom relief and a remarkable shortening of duration of the attack.

In a medical liability process a medical expert takes on an outstanding position. He is the one process participant who preprograms the decision of the judge. However, he does not as such have an independent investigative competence and must understand his role as being an accessory to the judge. ⋯ In contrast the procedure in criminal processes follows the principle of official investigation and the absolute principle of in dubio pro reo. From this it follows that the evidence of causality must be proven with a probability close to certainty. Advice for the construction of expert opinion statements can be found in this article.
