Summary
Spine surgery in thoracolumbar region is one of the most common surgeries performed for the
treatment of leg and back pain. Pain management is especially important for these patients
since chronic pain often occurs after surgery. Severe pain may occur at postoperative period
in patients following lumbar disc herniation (LDH) operation. Postoperative effective pain
treatment provides early mobilization and shorter hospital stay, thus complications due to
hospitalization such as infection and thromboembolism may be reduced.
Ultrasound-guided quadratus lumborum block (QLB) is a fascial plane block where local
anesthetic is injected adjacent to the quadratus lumborum muscle with the goal of
anesthetizing the thoracolumbar nerves.
The aim of this study is to evaluate the efficacy of US-guided QLB for postoperative
analgesia management after lumbar disc herniation-laminectomy surgery. The primary aim is to
evaluate postoperative pain scores (VAS), the secondary aim is to evaluate use of rescue
analgesia and adverse effects (allergic reaction, nausea, vomiting).
