Sugar water vs. salt water: which makes pain blocks last longer?
NCT ID NCT07386327
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two ways to dilute the numbing drug bupivacaine for a nerve block used during arm surgery. Researchers want to see if using sugar water (5% dextrose) instead of salt water (0.9% saline) affects how well and how long the block works. About 90 adults having elective upper arm surgery will take part.
