Serratus posterior superior intercostal plane block provides effective analgesia for patients undergoing dorsal mass excision: The first report of use in anesthesia practice

The ultrasound-guided serratus posterior superior intercostal plane (SPSIP) block is a newly introduced regional anesthesia technique that has shown promising results in adult patients undergoing uniportal video-assisted thoracoscopic lung resections and other thoracic procedures. However, its use in dorsal mass excisions has not yet been reported. In the reported case, a 66-year-old female patient received an SPSIP block for the surgical removal of a 7 cm lesion located in the upper scapular region. The surgery and postoperative period proceeded without complications, and the patient remained pain-free until discharge. This case underscores the SPSIP block's safety and effectiveness in providing postoperative analgesia for dorsal mass excision.
