Continuous postoperative analgesia via quadratus lumborum block - an alternative to transversus abdominis plane block

Different transversus abdominis plane blocks techniques cause variations in postoperative analgesia characteristics. We report the use of unilateral quadratus lumborum catheter for analgesia following colostomy closure. The catheter was placed under direct ultrasound visualization and had good outcomes: low pain scores and minimal use of rescue analgesic medication. No complications were reported in this pediatric patient. More studies are needed to evaluate the effectiveness and safety of this regional anesthesia technique.
