Sugar water vs. saline: which makes anesthesia last longer?
NCT ID NCT07386327
First seen Feb 04, 2026 · Last updated Jun 22, 2026 · Updated 25 times
Summary
This study compares two ways to dilute the numbing medicine bupivacaine for a nerve block in the arm. Researchers want to see if using sugar water (5% dextrose) instead of normal saline improves how well the block works and how long pain relief lasts. About 90 adults having arm surgery will take part, and their block success and pain levels will be tracked.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
bupivacaine diluted with 5% dextrose or 0.9% saline
What this could lead to
If successful, this could show that using dextrose water as a diluent improves nerve block success and pain relief after arm surgery.
What could go wrong
This is a small, early-phase study with only 90 participants, so results may not apply to everyone. The effect may be small or not clinically meaningful.
