In 2011 the first interdisciplinary S3 guideline for the management of patients with serious injuries/trauma was published. After intensive revision and in consensus with 20 different medical societies, the updated version of the guideline was published online in September 2016. ⋯ These two sections are of special interest for anesthesiologists in field emergency physician roles or as team members or team leaders in the emergency room. The present work summarizes the changes to the current guideline and gives a brief overview of this very important work.

Randomized Controlled Trial
[Sciatic nerve block "out-of-plane" distal to the bifurcation: effective and safe].
Ultrasound guided distal sciatic nerve block (DSB) at bifurcation level shows fast onset and provides excellent success rates. However, its safe performance might be difficult for the unexperienced physician. Just slightly distal to the bifurcation, the tibial nerve (TN) and common fibular nerve (CFN) can be shown clearly separated from each other. Therefore, we investigated if a block done here would provide similar quality results compared to the DSB proximally to the division, with a potentially lower risk of nerve damage. ⋯ DSB slightly distal to the bifurcation, in an out-of-plane technique between the TN and CFN, can be done fast, effectively and safe.

Adequate fluid therapy is highly important for the perioperative outcome of our patients. Both, hypovolemia and hypervolemia can lead to an increase in perioperative complications and can impair the outcome. Therefore, perioperative infusion therapy should be target-oriented. ⋯ Volume therapy step 2: Higher blood losses should be treated by using iso-oncotic, preferential balanced colloids in a ratio of 1:1. For this purpose hydroxyethyl starch can also be used perioperatively if there is no respective contraindication, such as sepsis, burn injuries, critically ill patients, renal impairment or renal replacement therapy, and severe coagulopathy. Volume therapy step 3: If there is an indication for red cell concentrates or coagulation factors, a differentiated application of blood and blood products should be performed.

A 43-year-old woman became exhausted and fainted on descent at 1127 MAMSL altitude and snowfall. A rescue team diagnosed asystole. With manual cardiopulmonary resuscitation (CPR) she was transported to the next extracorporeal life support (ECLS) center. ⋯ Two days later she was awake, orientated, and with no neurological deficits. With hypothermic cardiac arrest, a favorable outcome depends on early continuous CPR, triage, and ECLS rewarming. It holds true that "nobody is dead until they are warmed and dead" if one cools first and arrests thereafter.

Simulation assumes a growing importance in the field of emergency medical education. Many rescue service schools work with simulators or even have their own simulation center. Classic resuscitation training in the classroom is increasingly being replaced by realistic case scenarios. ⋯ Mid-fidelity simulators seem to be able to cover the widest range of imparting skills for emergency medical training. No matter what simulator is used, the following applies: The selected scenario must be realistic and the simulation as well as technical capabilities of the simulator must be coordinated. A well-presented scenario with a well-trained teacher using a simple resuscitation doll appears to be better than a highly complex, however unrealistic, amateur simulation scenario for successful learning.
