Tetracaine yog ib qho tshuaj sedative zoo uas siv los ua kom tawv nqaij lossis qhov ncauj. Nws nquag siv los ntawm cov kws kho hniav, kws kho hniav, thiab cov kws kho mob tshwj xeeb rau thaj tsam loog ua ntej cov txheej txheem xws li kev kho hniav, kab, lossis cov txheej txheem kho mob me.Tetracainehmoovua hauj lwm los ntawm impeding sodium directs nyob rau hauv cov hlab ntsha uas forestalls torment signals los ntawm raug xa tawm ntawm lub paj hlwb. Nws yog ib qho engineered ester sedative thiab muaj qhov chaw nrog cov amino ester sib sau ua ke ntawm cov zej zog sedatives.
tetracaine ua haujlwm li cas?
Tetracaine yog ib qho tshuaj sedative hauv zej zog uas ua haujlwm los ntawm kev cuam tshuam kev ua haujlwm ntawm cov hlab ntsha tsav tsheb. Nws txoj haujlwm ntawm kev ua haujlwm suav nrog kev cuam tshuam sodium particle diverts hauv paj hlwb zaj duab xis, uas yog qhov tseem ceeb rau kev pib thiab kev sib kis ntawm kev ua ub no. Los ntawm kev ua kom qeeb ntawm kev loj hlob ntawm sodium hais, tetracaine forestalls lub hnub nyoog thiab kev sib kis ntawm cov paj hlwb, ua rau luv luv tuag thiab tsis hnov tsw nyob rau hauv cheeb tsam uas nws tau thov.
Thaum daim ntawv thov, tetracaine diffuses los ntawm cov yeeb yaj kiab ntawm tes thiab kev sib raug zoo rau qhov chaw pom tseeb ntawm cov xov tooj sodium. Qhov kev txwv no daws cov kev coj ncaj ncees hauv lawv lub xeev latent, ua kom lawv tsis txhob qhib rau hauv lub teeb ntawm depolarization. Raws li, qhov dej ntawm sodium hais rau hauv cov hlab ntsha hlwb raug thaiv, ua rau muaj kev ntxhov siab thiab ua rau muaj kev ua ub ua no ntawm cov paj hlwb.
Tetracaine feem ntau yog siv cov tshuaj pleev ib ce los ua kom muaj kev ntxhov siab nyob ze ntawm cov yeeb yaj kiab mucous, zoo li lub qhov muag thiab qhov ntswg, thiab ntawm daim tawv nqaij.

Qhov pib sai thiab me ntsis kos tawm ntawm qhov kev ua si ua rau tetracaine yog ib qho khoom siv tseem ceeb rau kev ncua sij hawm los ntawm kev tsis xis nyob thaum lub sij hawm cov txheej txheem no.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum tetracaine muab kev zoo siab nyob ze, nws tsis cuam tshuam rau kev paub lossis kev xa paj hlwb. Kev siv tetracaine yuav tsum tau qhia los ntawm cov kws kho mob kom lav qhov tsim nyog koob tshuaj, daim ntawv thov, thiab tshuaj xyuas cov kev xav tau tom qab, xws li cov lus teb tsis zoo los yog kev tuav pov hwm lub hauv paus.
tetracaine siv rau dab tsi?
Tetracaine muaj ntau yam kev kho mob vim nws cov tshuaj loog. Qee qhov kev siv feem ntau suav nrog:
Cov txheej txheem kho hniav- Tetracainehmoovfeem ntau yog siv los ntawm kws kho hniav mus rau qhov chaw ntawm lub qhov ncauj ua ntej cov txheej txheem xws li txhaws, tshem tawm, cov chaw tso quav, thiab cov hauv paus hniav. Nws tuaj yeem siv tshuaj pleev xim rau cov pos hniav lossis txhaj ncaj qha rau hauv cov ntaub so ntswg. Tetracaine tso cai rau tus kws kho hniav ua haujlwm ntawm cov hniav tsis ua rau mob.

Kev kuaj mob- Cov kws kho mob tuaj yeem siv tetracaine txhawm rau txha caj pas lossis qhov ntswg qhov ntswg thaum kuaj. Qhov no tuaj yeem ua rau cov txheej txheem zoo li endoscopies yooj yim dua.
Nosebleed- Kev siv tetracaine hauv cov kab noj hniav tuaj yeem pab tswj cov hlab ntshav los ntawm kev txwv cov hlab ntsha. Qhov loog kuj txo qhov tsis xis nyob.
Mob hauv siab los ntawm angina- Hauv tsev kho mob, tetracaine tuaj yeem muab tso rau hauv cov hlab ntsha los pab txo qhov mob hauv siab los ntawm angina.
Kev phais qhov muag- Ophthalmologists siv tetracaine qhov muag tetracaine ua ntej cov txheej txheem xws li corneal abrasions thiab txawv teb chaws lub cev tshem tawm. Qhov no nums qhov muag.
Cov pob txha tawg- Tetracaine qee zaum raug txhaj rau hauv thaj chaw ib puag ncig cov pob txha tawg kom loog hauv cheeb tsam thaum rov kho dua lossis rov ua dua.
Yog li, hauv cov ntsiab lus, tetracaine lub peev xwm ua kom nrawm ntawm daim tawv nqaij thiab cov mucous membranes ua rau nws muaj ntau yam tshuaj loog rau ntau yam kev kho mob me me thiab kho hniav. Nws muab lub hom phiaj, ib ntus mob nyem.
Cov kev mob tshwm sim ntawm tetracaine yog dab tsi?
Thaum tetracaine muaj txiaj ntsig zoo ntawm thaj chaw ntawm lub cev, nws tuaj nrog qee qhov kev mob tshwm sim, tshwj xeeb tshaj yog tias siv tsis tsim nyog. Qee qhov kev mob tshwm sim muaj xws li:
Kev ua xua- Qee tus neeg yuav muaj kev fab tshuaj rau tetracaine uas tuaj yeem ua rau pob khaus, khaus, o, thiab ua pa nyuaj. Qhov no feem ntau tshwm sim hauv cov neeg uas muaj tshuaj loog ua xua.
Ntshai- Kev siv ntev lossis ntau dhau tuaj yeem ua rau loog loog uas siv sijhawm ntev dua los daws tom qab cov tshuaj hnav. Qhov no feem ntau yog ib ntus.

kiv taub hau- Kev siv tetracaine hauv pob ntseg tuaj yeem ua rau kiv taub hau ib ntus lossis vertigo.
qaug dab peg- Cov koob tshuaj ntau ntawm tetracaine tuaj yeem ua rau qaug dab peg, txawm tias qhov no tsis tshua muaj thaum siv kom raug.
Nco tsis tau- Kev txhaj tshuaj tsis raug nyob ze ntawm tus txha caj qaum yuav ua rau tsis muaj kev cuam tshuam rau tus txha caj qaum ua rau amnesia ib ntus.
Methemoglobinemia- Tshaj li cov koob tshuaj tetracaine tau pom zoo tuaj yeem ua rau cov ntshav oxygen tsis tu ncua.
Yog li thaum muaj kev nyab xeeb heev thaum siv kom raug, kev siv ntau tshaj cov lus qhia thiab kev siv tsis tsim nyog yuav ua rau muaj kev cuam tshuam tsis zoo. Kev saib xyuas yuav tsum tau ua kom ua raws li cov lus qhia kev kho mob thaum tau txais tetracaine.
Hauv cov ntsiab lus,Tetracainehmoovyog ib qho tshuaj loog hauv zos ceev ceev siv nyob rau hauv kev kho hniav, kev phais me, thiab cov txheej txheem uas yuav tsum tau siv cov tshuaj pleev ib ce luv luv. Nws blocks sodium channels tiv thaiv cov paj hlwb. Kev mob tshwm sim feem ntau yog me me tab sis yuav tsum tau saib xyuas kom siv qhov tsawg kawg nkaus uas yuav tsum tau ua. Thaum siv kom raug raws li kev saib xyuas kev kho mob, tetracaine tuaj yeem ua kom muaj kev nyab xeeb, txo qhov mob ib ntus.
