Abstract

Sodium nitroprusside, by a peripheral vasodilator action, is a powerful hypotensive drug. In contrast to established agents, its hypotensive action is accompanied by an unchanged or augmented cardiac output. Intravenous administration of sodium nitroprusside rapidly produces a profound and controllable hypotension. Normotension is swiftly restored by ceasing to infuse the agent, and antidotes are unnecessary. Its attributes make it especially suitable for neurosurgical anaesthesia, and although free cyanide is liberated during biotransformation, side effects are virtually absent provided that dosage is reasonable. Special contraindications to its use are hypothyroidism and altered cobalamin metabolism.

摘要

硝普钠是一种强效降压药,通过外周血管舒张作用起效。与已有的药物不同,其降压作用伴随着心输出量不变或增加。静脉注射硝普钠可迅速产生显著且可控的低血压。停止输注该药物后血压能迅速恢复正常,无需使用解毒剂。其特性使其特别适用于神经外科麻醉,尽管在生物转化过程中会释放游离氰化物,但只要剂量合理,几乎没有副作用。其使用的特殊禁忌证为甲状腺功能减退和钴胺素代谢改变。
