Double dose of numbing drug may slash opioid need after sarcoma surgery
NCT ID NCT04189783
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving a second numbing injection (quadratus lumborum block) after surgery for retroperitoneal sarcoma can reduce the need for opioid painkillers. About 113 patients will receive either one or two injections of liposomal bupivacaine. The goal is to see if the extra shot helps more patients leave the hospital without an opioid prescription, lowering the risk of long-term use or addiction.
