Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Previous studies have shown that PVB reduces pain and postoperative nausea and vomiting after breast cancer surgery when used in addition to general anesthesia or sedation. However, major breast cancer surgery involves areas beyond the breast tissue, such as pectoral musculature.
