  • Agent for preventing bleeding from cerebral cortical vein
    Patent number: 8926548
    Abstract: The present invention provides: a superficial cerebral vascular bleeding inhibitor comprising an aqueous solution containing 120 to 160 mEq/L of sodium ion, 1 to 5 mEq/L of calcium ion, and 75 to 165 mEq/L of chloride ion; the superficial cerebral vascular bleeding inhibitor further comprising 1 to 5 mEq/L of potassium ion; and a packaged container containing the superficial cerebral vascular bleeding inhibitor (with or without potassium ion). The superficial cerebral vascular bleeding inhibitor of the present invention can effectively prevent or inhibit bleeding from superficial cerebral blood vessels in the field of neurosurgery such as intracranial surgery and the like, thereby capable of securing a clear operating field during intracranial surgery and inhibiting the occurrence of post-surgery damage.
