Can a simple additive make eye surgery safer for the heart?

NCT ID NCT07675616

First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time

Summary

This trial tests whether adding dexmedetomidine or magnesium sulphate to lidocaine for a peribulbar block (anesthesia around the eye) helps keep heart rate and blood pressure steady during dacryocystorhinostomy (tear duct surgery) under general anesthesia. Sixty adults undergoing elective surgery will be randomly assigned to receive one of three mixtures. The goal is to find which additive provides better hemodynamic stability, reducing risks like reflex changes in heart rate during surgery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

dexmedetomidine and magnesium sulphate

What this could lead to

If one additive works better, it could become a standard way to keep patients stable during eye surgery under general anesthesia.

What could go wrong

This is a small, early-phase trial with only 60 participants, so results may not apply to everyone. Both additives are already used in other settings, so no major breakthrough is expected.
