Numbing shot volume studied for better Post-Surgery pain control
NCT ID NCT01307215
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether changing the amount (volume) of a numbing medicine called ropivacaine affects pain relief after abdominal surgery. 31 patients having a total abdominal hysterectomy received one of three different volumes injected into the abdominal wall. The goal was to see if a larger volume spreads the numbness further and reduces pain, and to check if a bigger study is possible.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Ropivacaine (a numbing medicine)
What this could lead to
If it works, this could help doctors choose the best volume of numbing medicine to control pain after abdominal surgery.
What could go wrong
This is a very small, early feasibility study (31 people) looking at how to measure effects, not yet proving which volume is best. Results may not apply to all surgeries or patients.
