C-Section anesthesia: does size matter?
NCT ID NCT07197398
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study analyzed data from 183 women who had a C-section under spinal anesthesia with a standard dose of bupivacaine. Researchers wanted to see if the mother's height, weight, or baby's size affected how high the numbness spread. The goal is to help doctors predict anesthesia effects more accurately.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- hyperbaric bupivacaine
- What this could lead to
- If successful, this could help doctors tailor spinal anesthesia doses for C-sections based on patient size, improving safety and effectiveness.
- What could go wrong
- This is a small, retrospective analysis, not a controlled trial. Results may not apply to other doses or populations, and the findings are exploratory.
