Acute right heart failure is often overlooked as a cause of cardiopulmonary insufficiency. The various pathologies underlying right heart failure at the level of afterload, preload and contractility, make rapid, targeted diagnostics necessary. In addition to clinical symptoms and laboratory chemical parameters, echocardiography in particular is relevant for making a diagnosis. ⋯ The focus is on a reduction of right ventricular pressure and afterload, a correction of systemic hypotension and positive inotropic support of the right ventricle. Mechanical organ replacement and support procedures are increasingly being used in the case of persistent right heart failure and expand the possibilities for treatment. Decisive for the prognosis is a causal treatment adapted to the underlying triggering disease.

In response to the global increase in antibiotic resistance, the concept of antibiotic stewardship (ABS) has become increasingly important in recent years. Several publications have demonstrated the effectiveness of ABS, mainly in university facilities. This retrospective observational study describes the implementation of ABS in a basic care hospital. ⋯ The preinterventional/postinterventional comparison showed a significant reduction in the overall consumption of antibiotics with a redistribution in favor of antibiotics with a lower resistance selection. At the same time, the resistance rate of E. coli decreased. The increase of the blood culture rate indicates the optimization of diagnostic procedures. This ABS program had to be established with reduced resources but this seems to have been compensated by the more personal contact addressing the care takers and short chain of commands, as is possible in smaller hospitals. Presumably, the structure of basic care hospitals is particularly suitable for concepts covering entire hospitals. Further clusters of randomized studies are necessary to confirm this.

Based on the German Transfusion Law, the periodically updated guidelines "Richtlinien zur Gewinnung von Blut und Blutbestandteilen und zur Anwendung von Blutprodukten" ("Hämotherapierichtlinien") are intended to provide the current knowledge and state of the art of blood transfusion practice in Germany. The novel update 2017 contains relevant changes for blood donation, especially the extension of the exclusion period of persons at risk for sexually transmitted HBV, HCV and HIV diseases to 12 months. Moreover, the guidelines provide several changes relevant to blood transfusion practice in anesthesiology, such as: all autologous hemotherapy procedures including normovolemic hemodilution, cell saver, and autologous blood donation and transfusion require formal registration at the regulatory authority. ⋯ Guidance is provided for the clinical situation of lacking consent for blood transfusion in emergency situations (under certain circumstances blood transfusion may still be allowed). For the first time, the concept of "patient blood management" is explicitly mentioned and recommended in the guidelines. Especially the novel regulations regarding autologous blood use impose new challenges in clinical practice in anesthesiology.

Inadvertent perioperative hypothermia, which is defined as a core body temperature of less than 36.0 °C, can have serious consequences in surgery patients. These include cardiac complications, increased blood loss, wound infections and postoperative shivering; therefore, the scientific evidence that inadvertent perioperative hypothermia should be avoided is undisputed and several national guidelines have been published summarizing the scientific evidence and recommending specific procedures. The German AWMF guidelines were the first to emphasize the importance of prewarming for surgery patients to avoid inadvertant perioperative hypothermia; however, in contrast to intraoperative warming, prewarming is so far not sufficiently implemented in clinical practice in many hospitals. Furthermore, a recent study has questioned the effectiveness of prewarming. ⋯ Prewarming, as recommended in the AWMF guidelines, resulted in a significant and clinically relevant reduction in the incidence of inadvertent perioperative hypothermia; therefore, prewarming can still be regarded as an effective method to avoid perioperative hypothermia. Hypothermia rates of 15.8% intraoperatively and 5.1% postoperatively can be achieved in clinical practice, when prewarming is performed in addition to intraoperative warming in the anesthesia induction room directly before the start of surgical procedures.

Capnocytophaga canimorsus is a Gram-negative bacterium present in the oral cavities of cats and dogs. It is known for its capability to cause life-threatening sepsis following a dog bite, especially in immunocompromised patients. We report the case of a 67-year-old man who suffered from septic shock and multiorgan failure presumably following contamination of a pre-existing minor skin lesion by canine saliva. The purpose of this report is to raise awareness of Capnocytophaga canimorsus among physicians when faced with a patient presenting with fulminant septic shock and Gram-negative bacteremia, who has been exposed to dogs.
