Clinical observation of acute left heart failure treated with sodium nitroprusside and nitroglycerin: Currently, for intravenous infusions lasting more than 6 days, they should be re-formulated. Due to its strong antihypertensive effect, it is necessary to closely monitor blood pressure, heart rate, respiration, and ensure that blood pressure does not fall below 100/60 mmHg. Sodium nitroprusside can decompose and produce thiocyanate; blood concentrations exceeding 20 µmol/L may lead to poisoning due to accumulation. Generally, the use of larger doses should not exceed 1 week.
