AbstractUltrasound imaging techniques in regional anaesthesia are becoming a subject of major interest. The quality of blocks and analgesia is relevant to the perioperative outcome of patients and the development of perfect blocks has always been a focus in regional anaesthesia research. Several studies in neuroaxial anaesthesia and peripheral blocks have found that puncture processing performed under ultrasound guidance is easier and more effective than that performed without such guidance, thus ultrasound imaging techniques are being developed for clinical practice. One of the major advantages of these techniques is that they provide the opportunity to show the patient the anatomical situation before the puncture--using a near harmless and effective technique. A second advantage is that the puncture process and the application of medication can be demonstrated and clearly observed during the performance. If there is a problem with the spread or the application, the processing of the block can be immediately modified to improve the quality of the technique.
