Serratus Anterior Plane Block to Address Postthoracotomy and Chest Tube-Related Pain: A Report on 3 Cases.

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.
