Can adding tramadol to spinal anesthesia extend pain relief after leg surgery?
NCT ID NCT07827352
First seen Sep 18, 2026 · Last updated Sep 18, 2026
Summary
Researchers compare two spinal anesthesia mixtures for pain relief after lower limb surgery. One group receives bupivacaine alone, and the other receives bupivacaine plus tramadol. The trial measures pain scores and how long it takes before patients need additional pain medicine. It includes 60 adults aged 17 to 80 who are having leg surgery under spinal anesthesia.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bupivacaine with tramadol
- What this could lead to
- If the combination works better, doctors could add tramadol to standard spinal anesthesia to give patients longer pain relief after leg surgery.
- What could go wrong
- This is a small Phase 4 study of 60 people at one hospital, so the results may not apply to everyone. Adding tramadol can cause nausea, vomiting, or drowsiness.
