硝普钠(sodium nitroprusside)是一种速效和短时作用的血管扩张剂,作用持续时间1~10 min,能在体内释放NO,强有力地扩张动脉和静脉。主要用于治疗高血压危象,全身麻醉时控制性降压,严重心力衰竭(心衰)中减轻前后负荷及伴随心肌梗死的严重心衰[1]。硝普钠含有44%的氰化物,这些氰化物可以不经过酶代谢,直接从硝普钠中释放出来。肾功能不全、输注速度过快、输注时间
Sodium nitroprusside is a fast-acting and short-acting vasodilator that lasts for 1 to 10 minutes and releases NO in the body to forcefully expand arteries and veins. Mainly used for the treatment of hypertensive crisis, controlled hypotension during general anesthesia, severe heart failure (heart failure) to reduce the load before and after severe heart failure accompanied by myocardial infarction [1]. Sodium nitroprusside contains 44% cyanide, which can be directly released from sodium nitroprusside without enzyme metabolism. Renal insufficiency, infusion rate too fast, infusion time
