Rhomboid Intercostal Plane Block in Breast Surgery: Current Evidence and Future Perspectives: Narrative Review

Vollständiger Abstract

Worum geht es in dieser Arbeit?

Rhomboid Intercostal Plane Block (RIB) has recently emerged as an effective and safe regional anesthesia technique for postoperative pain management in patients undergoing oncologic breast surgery. Postoperative pain control in oncologic breast surgery is critically important for both patient comfort and early mobilization. Studies have shown that RIB, especially with high-volume local anesthetic applications, can provide analgesia over a broad area of the thoracic wall and can also affect the intercostobrachial nerve. In patients who received RIB after oncologic breast surgery, opioid requirements were significantly reduced, pain scores decreased, and patient satisfaction increased. Additionally, cases with continuous infusion via catheter have been reported to be effective in postoperative pain control and to shorten hospital stays. Its minimal complication profile and ease of application make RIB an important tool in multimodal analgesia strategies. However, limited data on technical variations, optimal local anesthetic volumes, and long-term outcomes highlight the need for further randomized controlled studies. This narrative review examines the technical features, local anesthetic volumes, and clinical outcomes of RIB applications in the literature.
