NCT ID NCT07003698
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a rectointercostal nerve block can reduce pain and the need for strong painkillers after laparoscopic gallbladder removal. 60 adults having elective surgery received the block as part of their pain management plan. The goal was to see if it lowers opioid use during surgery and improves pain scores afterward.
