This study evaluated whether bilateral erector spinae plane block (ESPB) performed before abdominal hysterectomy could reduce postoperative pain and the development of chronic and neuropathic pain. Adult patients undergoing abdominal hysterectomy under general anesthesia were assigned to receive either bilateral ESPB with bupivacaine or standard perioperative analgesic management without ESPB. Postoperative pain was assessed during the early postoperative period and at 1 and 6 months after surgery. Chronic and neuropathic pain were evaluated at 1 and 6 months using validated pain assessment tools.

Chronic postoperative pain severity at 6 months
Chronic postoperative pain severity was assessed using the Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst pain imaginable).
Time frame: 6 months after surgery
