Which dose of spinal numbing is safer for bladder scopes?
NCT ID NCT07590544
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two strengths of a numbing medicine (bupivacaine) given as spinal anesthesia for cystoscopy, a procedure to look inside the bladder. Researchers want to see which dose keeps blood pressure and heart rate more stable. Sixty adults aged 18-80 will take part, and the goal is to find a dose that works well with fewer side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bupivacaine (a numbing medicine)
- What this could lead to
- If it works, this could help doctors choose the safest dose of spinal anesthesia for cystoscopy, reducing drops in blood pressure and heart rate.
- What could go wrong
- This is a small, early-phase trial with only 60 participants, so results may not apply to all patients. The two doses may show little difference in safety.
