[Peripheral regional anesthesia and analgesia: "the magnificent seven" for training]

Recent technological advances in ultrasound imaging have expanded the access routes for nerve and fascia blocks, opening up new perspectives. This has led to a significant increase in the number of published block techniques in regional anesthesia. Which specific regional anesthesiology techniques should be taught is currently not defined, even though the focus of the new postgraduate training regulations prior to admission to the anesthesia board examination now focuses on the acquisition of practical skills and ability to act rather than defined training time and numbers. The aim of this article is to propose frequent and established techniques for postgraduate training. The foundations for the recommendations were the establishment of interfascial blocks and the necessity of "motor sparing", which is increasingly considered to be an integral part of modern regional anesthesia concepts. These techniques are characterized by their ease of learning and an optimal risk-benefit profile. Proposals for regional anesthesia procedures in individual body regions are presented. A total of seven regional anesthesia procedures are proposed: axillary brachial plexus block (BPB), distal sciatic nerve block (DIB), interscalene BPB, femoral nerve block (NFB) together with the motor-sparing femoral triangle block (TFB), pericapsular nerve group block (PENG), transversus abdominis plane block (TAPB) with its variations and serratus anterior plane block (SAPB).
