Approximately 8000 patients with multiple trauma are admitted annually to an emergency room in Germany. The prognosis of these severely injured patients is influenced in particular by concomitant craniocerebral injury, an abdominal wound, or thoracic trauma. ⋯ Management of patients with multiple trauma poses a particular challenge to the responding team. This article in the continuing education series deals with current algorithms for preclinical management of patients with multiple injuries with particular focus on the significant factor of time.

The perioperative risk is mostly determined by the patient's cardiological condition and the type of surgical intervention. Therefore it is very important during the premedication visit to identify patients with cardiac risk factors. We suggest that patients be classified into three risk classes according to the ACC/AHA recommendations in advance of the preanaesthetic visit. ⋯ For the lowest risk no further evaluation is necessary. For the medium risk class an additional preoperative diagnosis or for the higher risk class a cardiological consultation or even postoperative intensive care monitoring could be necessary. The aim of such a system is to always minimise the rate of perioperative complications and delays in scheduled surgery.

Review Historical Article
[Nitrous oxide. Sense or nonsense for today's anaesthesia].
Nitrous oxide has been used in addition to other volatile anaesthetics to provide general anaesthesia and short time sedation for more than 150 years. However, the exact mechanisms of action remain unclear. For decades nitrous oxide was considered to be the ideal anaesthetic because of his favourable physical properties and low cardiovascular side effects. ⋯ Nitrous oxide is still frequently used for mask induction primarily in paediatric anaesthesia and gynaecology. However, recent studies have shown that omitting nitrous oxide can also be a risk factor because of an increased susceptibility to intraoperative awareness. Careful consideration of the illustrated contraindications and side effects as well as the available alternatives, shows that nitrous oxide is still an option in general anaesthesia.

Extracorporeal lung assist has been proposed as an invasive measure in patients with acute respiratory distress syndrome (ARDS) when oxygenation is critically impaired. However, this technique generally requires high personnel and technical resources. We report on a new system, which is characterised by a short circuit arterio-venous shunt using arterio-venous pressure gradient as driving force (pumpless extracorporeal lung assist [pECLA]). ⋯ pECLA represents a feasable and effective treatment in patients with severe ARDS. Compared with pump-driven systems pECLA is characterised by low costs and reduced personnel requirements. However, mortality remains high in patients suffering from severe ARDS despite newer treatment modalities.
