Summary
Brief summary (as posted)
This phase II trial studies how well a repeat or single liposomal bupivacaine injection (quadratus lumborum block) works in reducing opioid prescriptions after surgery in patients with retroperitoneal sarcoma. Liposomal bupivacaine is a numbing medication. Giving a second injection block may decrease dependency on opioid medications for pain relief after surgery and prevent long-term use and addiction.
