回 包容 的帖子
包容:1、快速房颤,160次,脸色苍白、四肢冰冷,病人极度恐惧、频死感,血压260/138,急性左心衰,舌下含服硝酸异山梨酯5毫克,十分钟后血压170/90,再含服5毫克,6分钟后血压140/75,病人心衰症状缓解 .. (2014-06-09 23:44) 沒有後續治療吧?
硝酸异山梨酯、硝普鈉都是硝類藥,是血管擴充劑,不是降壓藥,硝類藥常有陽藥
效果,但是毒性很大,不能長期用,只能急救時用用,標急救標,弄不好也能把人
毒死(見附文的英文原文資料)。這種不治病本,又能危及性命的藥,醫生還是得讓
病家自己去承擔風險,家屬簽字同意才給治,病人治死了也沒責任。如今醫生日子
是不好過,自保是需要的,但我不敢恭維說這是為病人著想。
NITROPRESS ® (Sodium Nitroprusside Injection) is not suitable for direct injection. The solution must be further diluted in sterile 5% dextrose injection before infusion.
NITROPRESS (nitroprusside sodium) can cause precipitous decreases in blood pressure (see DOSAGE AND ADMINISTRATION). In patients not properly monitored, these decreases can lead to irreversible ischemic injuries or death. Sodium nitroprusside should be used only when available equipment and personnel allow blood pressure to be continuously monitored.
Except when used briefly or at low ( < 2 mcg/kg/min) infusion rates, sodium nitroprusside gives rise to important quantities of cyanide ion, which can reach toxic, potentially lethal levels (see WARNINGS). The usual dose rate is 0.5-10 mcg/kg/min, but infusion at the maximum dose rate should never last more than 10 minutes. If blood pressure has not been adequately controlled after 10 minutes of infusion at the maximum rate, administration of sodium nitroprusside should be terminated immediately.
Although acid-base balance and venous oxygen concentration should be monitored and may indicate cyanide toxicity, these laboratory tests provide imperfect guidance.
This package insert should be thoroughly reviewed before administration of NITROPRESS (nitroprusside sodium) . |
