Quadratus lumborum Block

Abstract

Introduction: The majority of women who have planned cesarean section receive spinal anesthesia for the procedure. Typically, spinal opioids are administered during the same time as a component of multimodal analgesia to provide pain relief in the 16 – 24 hours period postoperatively. The ultrasound-guided quadratus lumborum block is emerged as a new regional analgesic technique that blocks T5 – L1 nerve branches and has an evolving role in postoperative analgesia for lower abdominal surgeries and may be a potential alternative to spinal opioids. If found effective, it would give the advantage of a reduction in opioid associated adverse effects while providing similar quality of analgesia.

We performed bilateral ultrasound- guided quadratus lumborum block in 50 women who received a spinal anesthetic for an elective cesarean delivery and evaluated their NRS, post-operative opioids consumption and patient satisfaction the first 24 hours after the block.

In all 50 patients, there were no additional opioids consumption during the first 24 hours after the block. The Numeric Rating Scale (NRS) for pain was less than 4 in the first 24 hours. Women were all very satisfied with the quality of pain relief.

Discussion: Ultrasound-guided quadratus lumborum block may be a promising anesthetic adjuvant for post-cesarean analgesia. Randomized controlled trials are needed to compare the efficacy of the ultrasound-guided quadratus lumborum block with intrathecal opioids.
