Norepinephrine, ʻike ʻia ʻo norepinephrine, kahi lāʻau i hoʻohana ʻia e kaohi i ke kahe o ke koko ma kekahi mau mokuʻāina ʻoi loa a me ke ʻano he mea kōkua i ka mālama ʻana i ka hopu ʻia ʻana o ka naʻau a me ka manaʻo nui hohonu.

Loaʻa kēia lāʻau lapaʻau ma ke ʻano he injection, ka mea e hoʻohana wale ʻia ma lalo o ke olakino olakino a pono e hoʻokō ʻia kāna hoʻokele e kahi ʻoihana olakino.

No ke aha ia

ʻO Norepinephrine kahi lāʻau i hōʻike ʻia e kaohi i ke kahe o ke koko ma kekahi mau mokuʻāina hypensive koʻikoʻi, i nā hanana e like me pheochromocytomectomy, sympathectomy, polio, myocardial infarction, septicemia, blood transfusion a me nā hopena i nā lāʻau.

Hoʻohui ʻia, hiki ke hoʻohana ʻia ma ke ʻano he kōkua i ka mālama ʻana i ka hopu ʻia ʻana o ka naʻau a me ka hohonu hohonu.

Pehea e ho ohana

ʻO Norepinephrine kahi lāʻau e pono ai e lawelawe ʻia e kahi ʻoihana olakino, i loko o ka wai, i loko o kahi hopena diluent. ʻO ka mahele lāʻau e lawelawe ʻia e pono ai kēlā me kēia kanaka e hoʻoholo ʻia e ke kauka.

Mekanism o ka hana

ʻO Norepinephrine kahi neurotransmitter me ka hana simpathomimetic, hana wikiwiki, me nā hopena i haʻi ʻia ma nā alpha-adrenergic receptors a me ka liʻiliʻi o ka haʻi ʻana ma nā beta-adrenergic receptor. No laila, pili ka hopena koʻikoʻi i ka hāpai ʻana i ke kahe o ke koko, kahi hopena o kāna hopena alpha-stimulate, ʻo ia ke kumu o ka vasoconstriction, me ka hoʻoliʻiliʻi o ke kahe o ke koko i nā puʻupaʻa, ke ake, ka ʻili a, pinepine, musculature skeletal.

ʻO wai ka mea pono ʻole e hoʻohana

ʻAʻole pono e hoʻohana ʻia ʻo Noradrenaline i ka poʻe hypersensitive i nā ʻāpana o ka haʻilula a i ʻole me mesenteric a i ʻole thrombosis vipher peripheral.

Hoʻohui ʻia, ʻaʻole pono e hāʻawi ʻia i ka poʻe i manaʻo nui ʻia ma muli o ka hemahema o ka nui o ke koko, koe wale nō ma ke ʻano he hana hoʻopilikia e mālama i ka perfusion coronary a me ka cerebral arterial a hiki i ka hoʻopau ʻia ʻana o ka hoʻoliʻiliʻi o ke koko, ʻoiai i ka wā anesthesia me cyclopropane a me halothane, e like me ka tachycardia ventricular a i ʻole fibrillation e kū.

Nā hopena ʻē aʻe

ʻO kekahi mau hopena ʻē aʻe i kū ma hope o ka lawelawe ʻana o norepinephrine he mau ʻeha ischemic, hoʻemi i ka helu o ka puʻuwai, hopohopo, ʻeha poʻo kuikawa, paʻakikī i ka hanu ʻana a me nā nekrosis ma ka pūnaewele injection
