First seen Jan 11, 2026 · Last updated Apr 29, 2026 · Updated 13 times
Summary
This study compared two methods of pain relief after breast removal surgery: a nerve block (SAPB) versus local anesthetic injected by the surgeon. The goal was to see which method reduces the need for strong painkillers (opioids) and improves arm movement. The study was withdrawn before enrolling any participants, so no results are available.
