Postoperative pain after spine surgery is a significant problem that affects recovery and increases the risk of complications. Traditional treatments, such as intravenous opioids, have side effects, leading to the search for new methods of pain management. Fascial plane blocks (FPB) represent a new technique of regional anesthesia that provides precise analgesia, easy application, high safety and low number of complications. Among the most commonly used FPBs in spine surgery is the erector spinae plane block (ESPB), which blocks nerve branches and provides long-term postoperative analgesia. Clinical studies show that ESPB reduces the need for opioids and improves pain control compared to other blocks, such as the thoracolumbar interfascial plane (TLIP) block. FPBs are part of multimodal analgesia and can prevent complications associated with general anesthesia and spinal anesthesia. However, research is still ongoing to more precisely determine the most effective techniques and their combinations for postoperative pain management in spine surgery[2][5][6][7].
