[Regional Anaesthesia in the Prehospital Setting].

Pain is often the main symptom in trauma patients. Although peripheral nerve blocks (PNB) provide fast, safe, and adequate analgesia, they are currently only rarely used outside the perioperative setting. In Germany, intravenous analgesia with non-opioid analgesics (NOPA) and strong opioids is the main treatment concept for prehospital pain. However, the use of highly potent opioids can be associated with significant side effects, especially in emergency patients. Therefore, PNBs are used in many hospitals for the treatment of perioperative pain. As with perioperative use, the advantages of early PNB in the prehospital analgesic treatment of trauma patients are obvious, especially for elderly and multimorbid patients. Early prehospital PNB can also facilitate the reduction of dislocated fractures or dislocated joints as well as the technical rescue of trauma patients. Common geriatric fractures, such as proximal femur or humerus fractures, can be treated appropriately and adequately with PNB.In this article, we show which PNB procedures can be useful in prehospital patient care and which requirements should be met for their safe use. We also present a concept for assessing whether and to what extent the prehospital use of PNB is indicated and appropriate. The aim of this article is to draw attention to PNB as a possible part of prehospital care concepts for trauma patients and to discuss its prehospital use.
