The ESP block can contribute significantly to a perioperative multimodal opioid-sparing analgesic regimen and enhance recovery after lumbosacral spine surgery.

In this case report, the serratus anterior plane block was used in conjunction with multilevel continuous thoracic paravertebral blocks (TPVB) and general anesthesia in 3 thoracotomy cases. All blocks were accompanied by use of catheters that allowed continuous local anesthetic infusions and intermittent local anesthetic bolus injections to address postoperative pain. In all 3 patients, the serratus anterior plane block provided analgesia for chest tube-related pain that was not provided by the TPVB alone.
