Ntawd yog, lub cev txoj kev npaj nws tus kheej rau "sib ntaus lossis khiav." Peb txhua tus tau hnov txog adrenaline, uas ua haujlwm hauv peb lub cev lub sijhawm no. Tab sis koj puas tau hnov txog nws tus kwv tij, uas ua haujlwm zoo ib yam li adrenaline, tab sis hauv txoj kev sib txawv me ntsis? Nws hu ua norepinephrine. Peb yuav tham txog ob qho no hnub no.
Cov catecholamines no yog dab tsi?
Hais yooj yim xwb, Norepinephrine thiab Epinephrine yog ob tug tswv cuab ntawm ib pawg ntawm cov tshuaj hormones hu ua 'Catecholamines' . Cov tshuaj hormones no yog tsim tawm hauv peb lub cev los ntawm ob lub qog me me uas nyob saum lub raum. Peb hu cov no ua 'Adrenal Glands'. Qee zaum cov no kuj raug tsim los ntawm lub hlwb ua 'Neurotransmitters' , cov tshuaj xa xov uas nqa cov lus hauv lub paj hlwb.
Tus tswv cuab tseem ceeb ntawm pawg no yog dopamine . Thaum koj xav ntshai, hem, lossis ntxhov siab, peb cov tshuaj hormones no ua haujlwm ua ke los npaj koj lub cev. Thaum cov no nyob rau hauv cov theem siab hauv koj lub cev,

Cov no ntau npaum li cas tas li tuaj yeem yog ib qho cim ntawm ib hom mob qog noj ntshav tsawg uas tshwm sim hauv cov qog adrenal.
Norepinephrine thiab Epinephrine - Ob Txoj Haujlwm rau Ob Tug
Txawm hais tias ob tug no ua haujlwm ua ke los, lawv cov haujlwm tseem ceeb txawv me ntsis. Cia peb saib seb qhov ntawd ua haujlwm li cas.
| Norepinephrine (Noradrenaline) | Epinephrine (Adrenaline) |
|---|---|
| Feem ntau yog ib qho neurotransmitterNws ua haujlwm ua tus xa xov hauv lub paj hlwb. | Feem ntau nws ua haujlwm zoo li ib yam tshuaj hormones . Thaum muaj xwm txheej ceev, nws raug tso tawm mus rau hauv cov ntshav los ntawm cov qog adrenal. |
| Nws ua haujlwm tas li hauv lub cev, tswj cov yam xws li kev pw tsaug zog, kev mloog zoo, thiab ntshav siab. | Feem ntau tsuas yog siv rau lub sijhawm muaj xwm txheej ceev xwb . |
| Lub luag haujlwm tseem ceeb yog tswj cov ntshav siab los ntawm kev txwv cov hlab ntsha. | Lub luag haujlwm tseem ceeb yog ua kom lub plawv dhia ceev dua, ua kom muaj zog ntxiv, thiab txo qhov kev hnov mob. |
Yuav ua li cas nrog norepinephrine?
Norepinephrine zoo li ib yam khoom tswj uas ib txwm qhib hauv peb lub cev. Nws tsis yog ua haujlwm thaum muaj xwm txheej ceev xwb, tab sis kuj ua haujlwm hauv lub neej txhua hnub.

- Kev Xav: Cov qib qis muaj feem cuam tshuam nrog kev nyuaj siab thiab lwm yam teeb meem kev noj qab haus huv ntawm lub hlwb. Tsis tas li ntawd, kev nce ntxiv ntawm norepinephrine sai sai tuaj yeem ua rau muaj kev zoo siab thiab ntshai heev .
Yuav ua li cas nrog Epinephrine (Adrenaline)?
Epinephrine yog adrenaline uas peb txhua tus paub. Nws yog tus uas los cawm zoo li ib tug phab ej thaum muaj xwm txheej ceev.

Cov no siv li cas los kho mob?
Vim yog ob qho tib si muaj zog thiab cov txiaj ntsig tam sim ntawd, cov kws kho mob kuj siv lawv ua tshuaj.
| Thaum twg yuav tsum muab Norepinephrine | Thaum twg yuav tsum muab epinephrine |
|---|---|
| Yuav kom ntshav siab nce thaum nws poob qis mus txog qib uas txaus ntshai rau lub neej (piv txwv li, septic shock, cardiac arrest). | Ua kom lub plawv rov qab muaj zog (CPR) thaum lub plawv nres. |
