What is the effect of nitroprusside on blood pressure during surgery?

Nitroprusside is a potent vasodilator frequently used during surgical procedures to manage hypertension. When administered, it leads to relaxation of vascular smooth muscle, resulting in a decrease in systemic vascular resistance and thus lowering blood pressure. This rapid reduction in blood pressure is beneficial in various surgical situations where control over hemodynamics is crucial. The effects of nitroprusside can be seen quickly, often within minutes, allowing for quick adjustments in blood pressure during surgery. Monitoring is essential because its potent effects can lead to hypotension if not managed carefully.
