Can extra drugs speed up eye numbing for surgery?
NCT ID NCT07519694
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares adding midazolam or cisatracurium to lidocaine for numbing the eye during vitreoretinal surgery. The goal is to see if these additives help the eye muscles paralyze faster. 90 adults having elective eye surgery will be randomly assigned to one of three groups. The main outcome is how quickly muscle paralysis occurs.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Midazolam and Cisatracurium added to lidocaine
- What this could lead to
- If it works, this could point toward a faster and safer numbing method for lengthy eye surgeries.
- What could go wrong
- This is a small, early-stage trial with only 90 participants. The additives may not work better than lidocaine alone, and could cause unexpected side effects.
