Allergic Reactions rau Hydroxyethylcellulose
Kev ua xua rau HEC yog qhov tsis tshua muaj tab sis tuaj yeem tshwm sim hauv cov tib neeg raug mob. Cov tshuaj tiv thaiv no tuaj yeem tshwm sim hauv ntau txoj hauv kev, suav nrog:
Daim tawv nqaij khaus: Cov tsos mob yuav muaj xws li liab, khaus, o, lossis pob liab liab ntawm qhov chaw sib cuag. Cov tib neeg uas muaj cov tawv nqaij rhiab tuaj yeem ntsib cov tsos mob no thaum siv cov tshuaj pleev ib ce lossis cov khoom tu tus kheej uas muaj HEC.
Cov tsos mob ua pa: Kev nqus HEC cov khoom, tshwj xeeb tshaj yog nyob rau hauv chaw ua haujlwm xws li chaw tsim khoom, tuaj yeem ua rau muaj cov tsos mob ua pa xws li hnoos, hawb pob, lossis ua tsis taus pa.
Kev ntxhov siab hauv plab: Kev noj HEC, tshwj xeeb tshaj yog nyob rau hauv ntau lossis hauv cov tib neeg uas muaj cov kab mob hauv plab ua ntej, tuaj yeem ua rau cov tsos mob xws li xeev siab, ntuav, lossis raws plab.
Anaphylaxis: Nyob rau hauv cov xwm txheej hnyav, kev tsis haum tshuaj rau HEC tuaj yeem ua rau anaphylaxis, ib qho mob hnyav rau lub neej uas tshwm sim los ntawm kev poob siab sai sai, ua pa nyuaj, thiab tsis nco qab.
Kev kuaj mob ntawm Hydroxyethylcellulose Allergy
Kev kuaj mob ua xua rau HEC feem ntau suav nrog kev sib xyaw ua ke ntawm keeb kwm kho mob, kuaj lub cev, thiab kuaj kev tsis haum. Cov kauj ruam hauv qab no tuaj yeem ua:
Kev Kho Mob Keeb Kwm: Tus kws kho mob yuav nug txog cov tsos mob, muaj peev xwm raug rau HEC-muaj cov khoom, thiab keeb kwm ntawm kev ua xua lossis kev tsis haum tshuaj.
Kev kuaj lub cev: Kev kuaj lub cev tuaj yeem pom cov tsos mob ntawm daim tawv nqaij khaus lossis lwm yam kev ua xua.
Patch Test: Patch testing suav nrog kev siv me me ntawm cov tshuaj tsis haum, suav nrog HEC, rau ntawm daim tawv nqaij txhawm rau saib xyuas cov tshuaj tiv thaiv. Qhov kev kuaj no yuav pab txheeb xyuas qhov ua xua rau tus kab mob dermatitis.
Daim tawv nqaij Prick Test: Hauv kev kuaj tawv nqaij prick, ib qho me me ntawm allergen extract yog pricked rau ntawm daim tawv nqaij, feem ntau ntawm lub forearm lossis nraub qaum. Yog tias ib tus neeg tsis haum rau HEC, lawv tuaj yeem tsim cov tshuaj tiv thaiv hauv zos ntawm qhov chaw ntawm qhov prick li 15-20 feeb.
Kev kuaj ntshav: Kev kuaj ntshav, xws li kev kuaj IgE (immunoglobulin E), tuaj yeem ntsuas qhov muaj HEC cov tshuaj tiv thaiv kab mob tshwj xeeb hauv cov hlab ntsha, qhia txog kev tsis haum tshuaj.
Kev Tswj Xyuas Tswv Yim rau Hydroxyethylcellulose Allergy
Kev tswj kev ua xua rau HEC suav nrog kev zam kom tsis txhob raug rau cov khoom uas muaj cov khoom xyaw no thiab siv cov kev kho mob tsim nyog rau kev ua xua. Nov yog qee cov tswv yim:
Kev zam: Txheeb xyuas thiab zam cov khoom uas muaj HEC. Qhov no yuav suav nrog ua tib zoo nyeem cov ntawv cim khoom thiab xaiv lwm cov khoom lag luam uas tsis muaj HEC lossis lwm yam khoom xyaw.
Hloov pauv: Nrhiav lwm cov khoom lag luam uas ua haujlwm zoo sib xws tab sis tsis muaj HEC. Ntau lub tuam txhab muab HEC-dawb formulations ntawm cov tshuaj pleev ib ce, khoom tu tus kheej, thiab tshuaj.
Kev Kho Mob: Cov tshuaj tom khw muag khoom xws li tshuaj tiv thaiv kab mob (xws li cetirizine, loratadine) tuaj yeem pab txo cov tsos mob ntawm kev tsis haum tshuaj, xws li khaus thiab pob khaus. Cov tshuaj pleev corticosteroids tuaj yeem raug tshuaj los txo cov tawv nqaij o thiab khaus.
Kev Npaj Thaum Muaj Xwm Ceev: Cov tib neeg uas muaj keeb kwm ntawm kev tsis haum tshuaj hnyav, suav nrog anaphylaxis, yuav tsum nqa cov tshuaj epinephrine auto-injector (xws li, EpiPen) txhua lub sijhawm thiab paub siv nws thaum muaj xwm txheej ceev.
Kev sab laj nrog cov kws kho mob: Sib tham txog kev txhawj xeeb lossis cov lus nug txog kev tswj hwm HEC kev tsis haum nrog cov kws kho mob, suav nrog cov kws kho mob ua xua thiab cov kws kho mob dermatologist, uas tuaj yeem muab kev qhia tus kheej thiab cov lus pom zoo kho mob.
Thaum hydroxyethylcellulose yog cov khoom siv dav hauv ntau yam khoom, kev ua xua rau cov tshuaj no muaj peev xwm, txawm tias tsis tshua muaj. Paub txog cov tsos mob thiab cov tsos mob ntawm HEC allergy, nrhiav kev ntsuam xyuas thiab kev kuaj mob uas tsim nyog, thiab siv cov tswv yim tswj kom zoo yog cov kauj ruam tseem ceeb rau cov tib neeg uas xav tias muaj qhov tsis haum no. Los ntawm kev nkag siab txog cov kev pheej hmoo uas cuam tshuam nrog HEC raug thiab ua kom muaj kev tiv thaiv kom tsis txhob kis tus kab mob allergen, cov tib neeg tuaj yeem tswj hwm lawv qhov tsis haum thiab txo qhov kev pheej hmoo ntawm kev tsis haum tshuaj.
