Patients with hypothermia are frequently encountered in emergency medicine. Particularly trauma patients, but also other predisposed persons, can be expected to suffer from hypothermia at any time of the year. ⋯ This paper first gives a brief overview of the typical clinical symptoms of hypothermia, before giving a detailed description of the preclinical and in-hospital management of the hypothermia patient. The various rewarming strategies are the subject of special attention and critical evaluation.

Managing the difficult airway poses an enormous challenge for anaesthesiologists, intensivists and A&E physicians, particularly because of the high probability of a potentially fatal outcome. Development and (pre-) clinical distribution of supraglottic airway devices (e.g. LMA, LT) and their enhancements, as well as the broad acceptance of awake fibre-optic intubation, led to a profound change in the strategy for managing the difficult airway. ⋯ In view of the utmost importance of this topic the German Society of Anaesthesiology and Intensive Care Medicine (DGAI) framed an independent German guideline, considering German national terms and conditions. In analogy algorithms and guidelines of the ILCOR, ERC and ATLS were revised as well as those of many other national anaesthesiological boards. Nevertheless, massive national and international deficits exist in implementing these guidelines into practice and the implicated structural requirements with respect to education, reflection, team building and equipment concerning the individual institution.

Fast-track rehabilitation refers to an interdisciplinary multimodal procedure to improve and accelerate recovery and avoid perioperative complications. The concept aims at reducing morbidity and discharging patients faster. It includes preoperative patient information, atraumatic surgical technique, stress reduction, pain therapy mostly via regional anesthetic techniques (frequently, thoracic epidural anesthesia), optimized fluid and temperature management, early enteral feeding, prophylaxis of gastrointestinal atony and postoperative nausea and vomiting, fast postoperative patient mobilization, and earlier hospital discharge. Fast-track protocols exist for all kind of surgical procedures but are best established for colon surgery.

[Ultrasound-guided anaesthesia of peripheral nerves. The new challenge for anaesthesiologists].
Ultrasound-guided anaesthesia of peripheral nerves is a new challenge for anaesthesiologists. The number of ultrasound users in this field has increased over the last 10 years because of improved high frequency ultrasound technology and increased mobility of machines. ⋯ Basic knowledge in ultrasound technology and image characteristics and a defined approach to blocking procedures to ensure sterile working conditions are necessary to guarantee optimal safety of patients. Furthermore economic questions and the implementation of a standardised education program are very important.

The rule of three describes three steps which are needed for an optimal control of postoperative nausea and vomiting (PONV). Firstly, patients at high risk of PONV need to be identified. Knowledge about predictive factors may help to identify patients who may best profit from prophylaxis and those where prophylaxis is not worthwhile since the baseline risk is too low. ⋯ Risk scores have been proposed and have been widely implemented in clinical practice. The sensitivity and specificity of such scores, however, remain particularly unsatisfactory. Unless more reliable risk scores are developed, aggressive treatment of established PONV symptoms may be more useful and more cost-effective than prophylaxis for many patients.
