Epinephrine . Epinephrine yog endogenous catecholamine uas ua rau beta-1, beta-2, thiab alpha-receptors. Vim nws cov inotropic, chronotropic, thiab vasoconstrictive teebmeem, epinephrine tshuaj yog vasopressor ntawm kev xaiv thaum lub plawv resuscitation.
Ib yam li ntawd ib tug yuav nug, dab tsi yog cov piv txwv ntawm vasopressors?
Cov tshuaj - suav nrog cov tshuaj hluavtaws - uas siv los ua vasopressors suav nrog:
- Norepinephrine.
- Epinephrine.
- Vasopressin (Vasostrict)
- Dopamine.
- Phenylephrine.
- Dobutamine.
Puas yog dobutamine yog vasopressor? Vasopressors nce vasoconstriction, uas ua rau kom muaj zog vascular tsis kam (SVR). Qhov loj vasopressors muaj xws li phenylephrine, norepinephrine, epinephrine, thiab vasopressin. Dopamine yog ib qho vasopressor nrog inotrope zog uas yog koob tshuaj-dependent. Dobutamine thiab milrinone yog inotropes.
Tib neeg kuj nug, vasopressors ua haujlwm li cas?
Vasopressors yog cov chav muaj zog ntawm cov tshuaj uas ua rau muaj vasoconstriction thiab yog li ua kom cov ntshav siab siab (MAP). Cov pawg tseem ceeb ntawm adrenergic receptors cuam tshuam rau vasopressor Kev ua haujlwm yog alpha-1, beta-1, thiab beta-2 adrenergic receptors, nrog rau cov dopamine receptors [2, 3].
Puas yog Epinephrine yog qhov zoo Inotrope?
Epinephrine muaj nyob rau hauv ntau yam kev npaj thiab siv tau tom qab IV, pulmonary, thiab qhov ntswg tswj. Txawm li cas los xij, vim qhov txo qis ntawm kev ua haujlwm ntawm lub plawv, epinephrine tshuaj tsis siv raws li a zoo inotropic tus neeg sawv cev tab sis theej rau kev kho mob xwm txheej ceev ntawm lub plawv nres thiab anaphylactic shock.

Puas yog epinephrine txo qis kev siv cov pa oxygen hauv myocardial?
Txawm hais tias koob tshuaj loj ntawm epinephrine ua rau kom lub siab ua kom lub siab khov thiab ntws thaum lub sij hawm cardiopulmonary resuscitation, epinephrine kuj tseem nce myocardial oxygen noj thaum lub sij hawm ventricular fibrillation
Puas yog mepivacaine muaj epinephrine?
Mepivacaine tsis nquag ua rau khaus lossis cov ntaub so ntswg puas. Levonordefrin yog cov tshuaj amine uas siv los ua vasoconstrictor hauv cov tshuaj loog hauv zos. Nws muaj cov tshuaj pharmacological zoo ib yam li Epinephrine tab sis nws ruaj khov dua li Epinephrine
Puas yog Epinephrine yog steroid lossis peptide hormone?
Steroid hormones yog insoluble hauv dej; lawv nqa los ntawm kev thauj cov proteins hauv cov ntshav. Raws li qhov tshwm sim, lawv tseem nyob hauv kev ncig ntev dua li peptide cov tshuaj hormones. Piv txwv li, cortisol muaj ib nrab-lub neej ntawm 60 txog 90 feeb, thaum epinephrine, cov amino acid tau txais los ntawm cov tshuaj hormones, muaj ib nrab-lub neej ntawm kwv yees li ib feeb
Dab tsi yog antiarrhythmic yog muab rau pulseless ventricular tachycardia VT thiab ventricular fibrillation VFIB uas tsis teb rau CPR defibrillation thiab vasopressor?
Amiodarone
Puas yog germaphobe puas yog kev puas siab puas ntsws?
Kev cai huv huv Germaphobes lub neej. Germaphobes muaj kev nyiam huv nrog kev huv thiab xav tias yuav tsum tau ntxuav ntau dhau, tab sis lawv tau raug kev txom nyem tiag tiag los ntawm kev tsis quav ntsej-yuam kev. Tib neeg feem ntau muaj ntau hom ntaub ntawv ntawm OCD
