Simple patient traits may predict epidural needle depth, reducing imaging needs
NCT ID NCT07697053
First seen Jul 10, 2026 · Last updated Jul 17, 2026 · Updated 2 times
Summary
This study looks at how factors like age, sex, and body mass index (BMI) affect the depth needed for epidural anesthesia in patients undergoing kidney stone surgery. The goal is to create simple models that help doctors estimate the right depth without relying on extra imaging. Researchers will analyze records from over 3,000 patients to find which traits matter most for different puncture sites.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could help anesthesiologists estimate epidural depth using simple patient details, reducing the need for extra imaging and improving safety.
- What could go wrong
- This is a retrospective study, so it can show associations but not prove cause. The models may not work well for people outside the studied population.
