Summary

Quadratus lumborum block can be used for the hip surgery and abdominal surgery postoperative analgesia. But the lower thoracic to the hip dermatome can't be blocked at the same time. The anesthetists used the same method, but had produced the different dermatome were blocked. The investigators hypothesized that this was due to local anesthetics was injected to different locations of the anterior thoracolumbar fascia. If the investigators inject local anesthetics to the anterior layer of thoracolumbar extrafascial, this produced the dermatomal coverage from lower abdominal to hip. A different situation was when the investigators injected local anesthetics to anterior thoracolumbar subfascia, the lower thoracic dermatome were blocked.
