过敏性休克为什么首选肾上腺素 徐娟 徐州矿务集团总医院

过敏性休克为什么首选肾上腺素 徐娟 徐州矿务集团总医院 过敏性休克首选肾上腺素是因为肾上腺素是一个叫肾上腺能受体激动剂，可以快速地刺激心脏、刺激心跳然后会收缩血管、纠正低血压，所以它是一个急救的药物。但是最开始都是肌注给药让它快速起效，如果效果不好必要时可以重复，但在给肾上腺素的同时要其他方法包括静脉通路、CPR整条呼吸循环都要给起来，不能光是只给肾上腺素。肾上腺素属于ab受体激动剂，可以增强心排出量，增加心率，同时还可以解除支气管痉挛，并收缩周围的血管及皮肤的黏膜血管，是各种休克的首选。过敏性休克是由于细小血管扩张，引起人体的血压下降、支气管痉挛、呼吸困难，在这种情况，如果给肾上腺素的话，它最主要可以使血管收缩的血压能够回升，而肾上腺素可以收缩血管、兴奋心脏引起血压增高，消除水肿，达到缓解呼吸困难，解除休克的目的，而且也使得血管收缩之后它这些过敏的炎性介质减少外渗，就减少了整个过敏对机体的造成的伤害。因此作为过敏性休克的首选药。过敏性休克出了血压降低的时候，是一个很重的表现。，所以它是建议的首选，而且是非常有效的。 Why adrenaline is the first choice in anaphylactic shock Adrenaline is the first choice in anaphylactic shock because adrenaline is an adrenergic receptor agonist, It can quickly stimulate the heart, stimulate the heartbeat, then contract blood vessels, correct hypotension, So it's an emergency medicine. But at first, it was intramuscular injection that made it work quickly, If the effect is not good, it can be repeated if necessary, But in addition to epinephrine, other methods, including venous access, CPR, and the whole respiratory cycle should be given, You can't just give adrenaline. Adrenaline is an ab receptor agonist, It can enhance cardiac output, Increase heart rate, It can also relieve bronchospasm, And contract the surrounding blood vessels and the mucosal blood vessels of the skin, It is the first choice for all kinds of shock. Anaphylactic shock is caused by dilation of small blood vessels, It causes blood pressure drop, bronchospasm and dyspnea, In this case, If you give adrenaline, It is mainly used to make the blood pressure of vasoconstriction rise, Epinephrine can constrict blood vessels, excite the heart and increase blood pressure, Eliminate edema, To relieve dyspnea, The purpose of relieving shock, And it also reduces the extravasation of these allergic inflammatory mediators after vasoconstriction, It reduces the damage caused by the whole allergy to the body. Therefore, it is the first choice for anaphylactic shock. When anaphylactic shock reduces blood pressure, It's a very important performance. So it's the recommended choice And it's very effective
