Timing of pain block could slash opioid use after surgery
NCT ID NCT07064200
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether giving a TAP block—a numbing injection in the belly wall—before surgery works better than giving it after surgery to control pain and reduce opioid use. Researchers will track pain scores and opioid amounts in 150 adults having elective abdominal or weight-loss surgery. The goal is to find the best timing to improve recovery and cut down on strong painkillers.
