Ultrasound‐guided peripheral trunk block technique: A new approach gradually stepping onto the stage of clinical anesthesia

In recent years, with the continuous development and validation of new visualization, ultrasound-guided peripheral trunk block becomes more mature has a extensive broader implementation scope in clinical anesthesia. Based on this, we reviewed summarized literature nerve include: paraspinal block, retrolaminar plane erect spinal muscle, transverse convex to pleural midpoint trapezius muscle anterior serratus thoracic abdominal fascia type-I quadratus lumborum, type-II type-III sheath rectus abdominis. This paper reviews technique, including history, anatomic basis, methods, advantages disadvantages describes bottleneck difficulties technique at present.
