    Summary

    Sodium nitroprusside effectively lowers blood pressure in patients undergoing neurosurgery and vascular procedures. This hypotensive drug demonstrated prompt efficacy with manageable side effects like increased heart rate and decreased central venous pressure.

    Area of Science:

    • Anesthesiology
    • Pharmacology

    Background:

    • Sodium nitroprusside is evaluated as a hypotensive agent.
    • Comparison with halothane and trimetaphan.

    Purpose of the Study:

    • Assess blood pressure lowering efficacy of sodium nitroprusside.
    • Evaluate potential side effects of sodium nitroprusside.

    Main Methods:

    • Group 1: 7 patients underwent induced hypotension during neurosurgery.
    • Group 2: 5 patients received nitroprusside for hypertensive crisis during vascular surgery.

    Main Results:

    • Prompt and sufficient blood pressure reduction observed in all patients.
    • Average heart rate increased by 22.5%; central venous pressure decreased by 66%.
    • Mild metabolic acidosis occurred, deemed clinically insignificant.

    Conclusions:

    • Sodium nitroprusside is a highly effective hypotensive drug.
    • Its use is well-suited for modern anesthesia practices.
    • Demonstrated utility in both neurosurgical and vascular procedures.
