Conditions
Brief summary
This study is a randomized, controlled, double-blinded, and parallel design study. A total 64 patients will be randomized to receive midazolam or normal saline during unruptured intracranial aneurysm clipping surgery.
Interventions
Midazolam (0.03 mg/kg/30 min) will administered during UIA clipping through microscope.
Normal saline (0.03 mg/ml/30 min) will administered during UIA clipping through microscope.
