Summary
Recently, the uses of peripheral axial blocks that deliver local anesthetic into the
transversus abdominis fascial plane have become popular for operations that involve
incision(s) of the abdominal wall. Thus, the Transversus Abdominis plane (TAP) block has been
shown to reduce perioperative opioid use in elective abdominal surgery, including open
appendicectomy, laparotomy, and laparoscopic cholecystectomy.
Currently, the Quadratus Lumborum block (QL block) is performed as one of the perioperative
pain management procedures for all generations (pediatrics, pregnant, and adult) undergoing
abdominal surgery. The local anesthetic injected via the approach of the posterior QL block (
QL 2 block ) can more easily extend beyond the TAP to the thoracic paravertebral space or the
thoracolumbar plane, the posterior QL block entails a broader sensory-level analgesic and may
generate analgesia from T7 to L1. Use of posterior QL block in laparoscopic prostatectomy has
not been investigated before and it is the variant that will be discussed in our study.
