Summary

This study tests two methods of giving the anesthetic remimazolam during cerebrovascular bypass surgery in people with moyamoya disease. One method uses a computer-controlled pump (TCI), the other uses manual weight-based dosing. The goal is to see which approach uses less total anesthetic. 58 adults will be randomly assigned to one of the two methods.

What this could mean

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

Active substance: Remimazolam (an anesthetic drug)
What this could lead to: If successful, this could help doctors use less anesthetic during brain surgery, potentially reducing side effects and costs.
What could go wrong: This is a small, early-stage study (58 people) focused on drug dosing, not on curing or treating moyamoya disease. Results may not apply to other surgeries or patients.
