Postoperative pain management in breast surgery and video-assisted thoracic surgeries (VATS) remains challenging. Oral or intravenous infusion of opioids were early treatments, but they can result in gastrointestinal reactions, respiratory inhibition, and other adverse reactions. In recent years, various regional block techniques have been employed for postoperative analgesia of these surgeries. However, a pair-wise meta-analysis cannot comprehensively rank and evaluate the analgesic effects and adverse events of various regional blocks.
