Because of new surgical techniques, advanced monitoring modalities and improvements in perioperative care, perioperative mortality and morbidity have been significantly reduced in the last decades; however, patients still suffer from high perioperative mortality and morbidity, especially those with pre-existing cardiovascular diseases. Not only perioperative myocardial infarction but also myocardial injury after non-cardiac surgery, which presents without clinical symptoms, is associated with an adverse outcome. Patients at risk require particular interdisciplinary attention throughout the perioperative phase. ⋯ This is relevant in the time period when a significant proportion of patients have already left the monitoring ward. The recently published recommendations by the World Health Organization concerning perioperative hyperoxia might not be beneficial for patients with an elevated cardiovascular risk. Finally, the treatment options for perioperative cardiovascular events are explained and an algorithm for handling of patients with perioperative myocardial injury without clinical ischemic symptoms is suggested (myocardial injury after non-cardiac surgery).

The increase in resistant pathogens has long been a global problem. Complicated life-threatening infections due to multidrug-resistant pathogens (MRD) meanwhile occur regularly in intensive care medicine. An important and also potentially modifiable factor of the rapid spread of resistance is the irrational use of broad spectrum antibiotics in human medicine. ⋯ They are not uncommonly the leading reason of difficult to treat infections and the failure of known routinely used broad spectrum antibiotics, such as cephalosporins, (acylamino)penicillins and carbapenems. Strategies for containment of MRDs primaríly target the rational use of antibiotics. In this respect interdisciplinary treatment teams, e.g. antibiotic stewardship (ABS) and infectious diseases stewardship (IDS) play a major role.

Dexamethasone is a synthetic steroid that has been used for many years in the clinical routine due to its anti-inflammatory, anti-allergic and immunosuppressive properties. Furthermore, dexamethasone has been used for a long time for prophylaxis and treatment of chemotherapy-induced nausea and vomiting. In the meantime dexamethasone has been approved as standard for the prophylaxis and treatment of postoperative nausea and vomiting (PONV). This review article outlines the indications and side effects of the perioperative administration of dexamethasone.

Following a terrorist attack a second hit is to be feared. The adequate reaction of the emergency services on site is to clear the scene. Since in such cases no treatment areas are set up at the scene of the incident, the injured are quickly admitted to the nearest hospital, either by themselves or by the emergency services and are largely untreated. Therefore, the hospital has to be ready to take in a significantly larger number of injured people in a very short period of time than after a conventional mass casualty incident. Due to the conceivably large number of wounded persons the emergency department can ensure primary medical care but nowhere near all casualties admitted to the hospital can be definitively treated. ⋯ The University Hospital of Ulm has made preparations to admit at least 100 injured patients for initial medical treatment following a terrorist attack. This corresponds to 10% of the hospital beds as required in the literature. Together with the neighboring Military Hospital and the University and Rehabilitation Hospital Ulm up to 300 injured patients can be treated; however, the number of available intensive care unit (ICU) beds and capacities in normal wards for definitive care is much lower, therefore, patients treated according to the principles of damage control resuscitation have to be relocated. By documenting the capacity of the hospitals within a 100 km radius around Ulm and taking their specific features into account, an exit wave plan could be created that enables patient distribution for definitive care without time-consuming procedures.

Acute pain is a common reason for calling emergency medical services (EMS) and can require medication depending on the pain intensity. German EMS personnel feel strong pressure to reduce a patient's pain but are restricted by law. Currently, German federal law only allows the administration of opioid-containing drugs by or on the order of a physician, while in other European countries (e.g. Switzerland and The Netherlands) the administration of opioid-based analgesia by trained and certified paramedics is common practice. Consequently, a patient in Germany experiencing acute pain needs the attendance of an emergency physician in EMS missions. According to international standards pain reduction on the numeric rating scale (NRS) score by ≥2 or a NRS score ≤4 at the end of the patient transport is considered to be adequate. ⋯ The administration of analgesia by EMS personnel with teleconsultation of a physician is effective and has a low rate of complications, particularly morphine. Overall, algorithm-based call back-supported as well as telemedically supported analgesia concepts based on regular training improve the management of pain in the prehospital setting. In addition, the resources of the emergency physician remain available for life-threatening emergencies. The training, certification and supervision of EMS personnel is very important in both systems to ensure the best pain management care and patient safety. Adjustments to the federal law on the administration of analgesics would facilitate the realization of algorithm-based concepts by paramedics as pain reduction could be performed with delegation by a medical director without consulting another physician.
