Summary

: Spine surgery induced severe postoperative pain. Several techniques as intravenous multimodal analgesia have been proposed to reduce pain relief and morphine rescue over the first postoperative days. Regional anesthesia using the erectus nerve block is a simple infiltration across lamina of the vertebra: Ultrasound-guided posterior ramus of spinal nerve block for anesthesia and analgesia in lumbar spinal surgery This study compared erector nerve block with local anesthetic vs placebo to reduce pain and morphine rescue after lumbar spine surgery. The investigators hypothesized that eructor nerve block induced a large block from L1 to L5 that induced posterior nerve roots block anesthesia. This block reduced pain after surgery.
