Is nitroprusside still used?
It is used clinically in cardiac surgery, hypertensive crises, heart failure, vascular surgery, pediatric surgery, and other acute hemodynamic applications. In some practices, newer agents have replaced nitroprusside, either because they are more effective or because they have a more favorable side-effect profile.
Which action by sodium nitroprusside decreases blood pressure?
Once in the body, sodium nitroprusside is quickly broken down into nitric oxide, a powerful vasodilator. This nitric oxide works as a vasodilator, causing the muscles surrounding blood vessels to relax, allowing the blood vessels themselves to expand. As the blood vessels expand, blood pressure drops.
What is meant by sodium nitroprusside?

Does nitroprusside increase blood pressure?
With increasing rates of infusion, sodium nitroprusside has been able to lower blood pressure without an observed limit of effect. Clinical trials have also shown that the hypotensive effect of sodium nitroprusside is associated with reduced blood loss in a variety of major surgical procedures.
What type of drug is nitroprusside?

Is sodium nitroprusside toxic?
Sodium nitroprusside causes toxicity by three primary mechanisms: 1) the most common adverse effect is direct vasodilation resulting in hypotension and dysrhythmias; 2) thiocyanate toxicity occurs infrequently, resulting in tinnitus, altered mental status changes, nausea, and abdominal pain; 3) in rare cases, cyanide …
When do we use nitroprusside?

What is the mechanism of action of furosemide?
Furosemide, an anthranilic acid derivative, is a rapid acting, highly efficacious diuretic Rankin (2002). Its mechanism of action is inhibition of the sodium-potassium-2 chloride (Na+-K+-2 Cl−) co-transporter (symporter) located in the thick ascending limb of the loop of Henle in the renal tubule Jackson (1996).

What is the clinical significance of the sodium nitroprusside test?
The nitroprusside test is used to detect the presence of ketoacids in the blood and the urine. This test measures only acetoacetate and acetone; therefore, it may underestimate the degree of ketonemia and ketonuria, because it will not detect the presence of beta-hydroxybutyrate (BOH).
What is the antidote for nitroprusside?
Treatment of cyanide toxicity requires the cessation of nitroprusside and, for severe toxicity, use of the cyanide antidote kit. Cyanide toxicity from nitroprusside may be prevented by concomitant administration of sodium thiosulfate infusions.
What is the Colour of sodium nitroprusside?
1. Sodium nitroprusside test. During the preparation of Lassaigne’s extract, sulphur from the organic compound reacts with sodium to form sodium sulphide. It gives a purple colour with sodium nitroprusside due to the formation of sodium thionitroprusside.
Does nitroprusside have cyanide?
Mechanism of toxicity.
Nitroprusside is rapidly hydrolyzed (half-life, 11 minutes) and releases free cyanide, which normally is converted quickly to thiocyanate by rhodanase enzymes in the liver and blood vessels.

Is sodium nitroprusside light sensitive?
Special considerations. Sodium nitroprusside is sensitive to light, heat and moisture. Exposure to light causes deterioration that may be observed as a change in color from brown to blue caused by reduction of the ferric ion to a ferrous ion.

Conclusion. The combination of nitroprusside and thiosulfate is chemically and physically stable as a single compounded dose for up to 48 hours when stored at room temperature and protected from light.
