Which IV fluid spares kidneys best during back surgery in seniors?
NCT ID NCT07542353
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 174 older adults (ages 65-80) having lumbar fusion surgery to see whether using sodium acetate Ringer's solution or sodium lactate Ringer's solution during the operation better protects the kidneys. Researchers measured early kidney injury markers in urine and blood after surgery. The goal is to find out which fluid might reduce the risk of acute kidney injury in this vulnerable group.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Sodium acetate Ringer's solution vs. sodium lactate Ringer's solution
What this could lead to
If one fluid is clearly better, it could guide safer fluid choices during spine surgery in older adults, potentially reducing kidney damage.
What could go wrong
This is a small, completed study with 174 patients, so results may not apply to all surgeries or populations. The findings are about biomarkers, not long-term health outcomes.
