In 2015 practice management guidelines on prehospital emergency anesthesia in adults were published in Germany. The aim of the present study was to evaluate whether emergency physicians follow these guidelines in daily practice and to assess their level of experience with the use of anesthetic agents. ⋯ The results of this survey demonstrate that clinical practice of emergency physicians is in high accordance with the recommendations named in the guidelines for prehospital emergency anesthesia in adults (except for cardiac patients and time of preoxygenation). With respect to the lower levels of experience of non-anesthetists in the use of anesthetic drugs, specific training concepts may help to further improve the quality of preclinical emergency care.

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.

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.

Interscalene regional anesthesia is an established and highly effective procedure; however, it represents an increased level of risk due to the close proximity of anatomical structures, such as the cervical spinal cord and many vessels. Furthermore, due to inadvertent placement of a catheter close to the cervical spinal cord or into a vessel, as opposed to a single shot injection technique, it remains a latent danger until it is removed. ⋯ The etiology and symptoms are discussed as well as recommendations regarding the prevention of catastrophic complications. As a result, internal practice guidelines are recommended for anesthesia departments in order to enhance the safety and quality of regional anesthesia.

Randomized Controlled Trial
Determination of the median effective dose (ED50) of bupivacaine and ropivacaine unilateral spinal anesthesia : Prospective, double blinded, randomized dose-response trial.
Unilateral spinal anesthesia (USpA) has been reported to potentiate spinal anaesthesia and is used in geriatric patients. The purpose of this study was to determine the median effective dose (ED50) of 0.5% hypobaric bupivacaine and 0.5% hypobaric ropivacaine USpA for geriatric patients (age ≥ 70 years) undergoing elective hip replacement surgery. ⋯ We find the ED50 were lower, and the ED50 of 0.5% hypobaric bupivacaine and ropivacaine was 4.66 mg (95% CI 4.69-4.63 mg) and 6.43 mg (95% CI 6.47-6.39 mg), respectively, for USpA in geriatric patients (age ≥ 70 years) undergoing elective hip replacement surgery.
