This atlas demonstrates to the anesthetist how patients, especially those in risk groups, can profit from intraoperative peripheral blocks compared to general anesthesia and paraspinal block. This atlas describes the different techniques, their advantages (and disadvantages) and how the author's have modified techniques to reflect their own extensive experience in peri- and postoperative pain management. Anatomical sections and drawings complement the clear photographs taken from the anesthesist'..s point of view, conveying clearly to the reader just how a regional block can be performed in a way which will avoid unnecessary complications. Descriptions of the materials and instruments, as well as the anesthetic medication and dosages, complement this very instructive atlas of peripheral regional anesthesia techniques.
