The efficacy of ultrasound-guided anterior quadratus lumborum block for pain management following lumbar spinal surgery: a randomized controlled trial.

ABSTRACT:

Background

Quadratus lumborum block (QLB) is a fascial plane block. There is no randomized study on the efficacy of QLB for lumbar surgery. We evaluated the efficacy of QLB for postoperative pain management and patient satisfaction after lumbar disc herniation surgery (LDHS).

Methods

Sixty patients with ASA score I-II planned for LDHS under general anesthesia were included. We allocated the patients into two groups: the QLB group (n = 30) or the control group (n = 30). QLB was performed with 30 ml 0.25% bupivacaine in the QLB group. Paracetamol 1 g IV 3 × 1 was ordered to the patients at the postoperative period. If the NRS score was ≥ 4, 1 mg/ kg tramadol IV was administered as rescue analgesia.

Results

There was a reduction in the median static NRS at 0 h and 2 h wi
