Tshuaj lom koob tshuaj lom ntawm barium thiab nws cov tebchaw

Qiathiab nws cov tebchaw
Lub npe yeeb tshuaj hauv Suav: Qia
Lus Askiv Lub Npe:Qia, Ba
Toxic Mechanism: QiaYog ib qho muag muag, kob dawb luster alkaline lub ntiaj teb hlau uas muaj nyob rau hauv cov qauv ntawm cov tshuaj lom (baco3) thiab neeb oo4). Barium sib txuas ua ke yog siv dav hauv ceramics, kev lag luam iav, barium tshuaj pleev, barium carbonate, barium nitrace, barium sulfate, barium sulfate,Barium oxide, Barium Hydroxide, Barium Stearate, thiab lwm yam.Barium hlauYog yuav luag tsis muaj tshuaj lom, thiab cov tshuaj lom ntawm barium concounds yog hais txog lawv solubility. Soluble Barium cov tebchaw tau muaj kuab heev, thaum yuav luag tsis muaj dej hauv hydubyloric acid los ua cov yeeb yaj kiab barium. Lub ntsiab lus tseem ceeb ntawm Barium lom yog qhov thaiv ntawm cov calcium nyob hauv cov poov xab, uas ua rau muaj cov poov tshuaj ntau ntxiv, ua rau muaj cov tshuaj hypokalemia; Lwm tus kws tshawb fawb ntseeg tias Barium ions tuaj yeem ua rau cov tsos mob arhythmia thiab cov tsos mob plab zom mov los ntawm kev txhawb nqa ncaj qha rau myocardium thiab du cov leeg. Qhov nqus ntawm solubleqiaCov tebchaw hauv plab zom mov yog zoo ib yam li ntawm calcium, suav rau kwv yees li 8% ntawm tag nrho cov koob tshuaj. Cov pob txha thiab cov hniav yog cov chaw tso nyiaj tseem ceeb, suav rau ntau tshaj 90% ntawm tag nrho lub cev thauj khoom.Qiakev ingested orally yog feem ntau yog ua tiav los ntawm cov quav; Feem ntau ntawm cov barium lim los ntawm ob lub raum yog reabsorbed los ntawm lub raum renal tubules, nrog tsuas yog ib qho nyiaj me me uas tshwm nyob rau hauv cov zis xwb. Kev tshem tawm ib nrab-lub neej ntawm barium yog li 3-4 hnub. Cov hmoov av lom feem ntau yog tshwm sim los ntawm kev noj ntawm barium sib txuas, cov hmoov, thiab lwm yam, thiab lwm yam. Kuj muaj cov dej haus tsis huv nrog cov khoom sib xyaw barium. Kev ua hauj lwm Barium kev lom zem yog tsis tshua muaj thiab tsuas yog nqus tau ntawm daim tawv nqaij lossis cov tawv nqaij puas. Kuj tseem tau tshaj tawm cov tshuaj lom lom uas tau los ntawm kev raug mob barium stearate, feem ntau yog subacute, feem ntau yog nyob rau sab nraud thiab latent lub sij hawm ntawm 1-10 lub hlis. AI cov cuab yeej yuav txhim kho kev ua haujlwm tau zoo, thiabUndetectable AIkev pabcuam tuaj yeem txhim kho cov cuab yeej AI zoo.

Meem
Cov tshuaj lom tau tshuaj lom neeg noj barium chloride yog li 0.2-0.5g
Lub deethal koob rau cov laus muaj kwv yees li 0.8-1.0g
Cov kev kho mob ua kom zoo: 1. Qhov tsim kom muaj zog ntawm kev lom neeg feem ntau yog 0.5-2 teev, thiab cov uas lom tau cov tsos mob nyob rau 10 feeb.
(1) Cov tsos mob hnyuv nyob thaum ntxov: hlawv cov quav, mob plab, thiab mob plab, thiab loog hauv lub qhov ncauj, ntsej muag, thiab nqua.
(2) Cov leeg ua haujlwm ua txhaum cai: Cov neeg mob pib ua txhaum kev tuag tes tuag taw, tus leeg nqaij, tus nplaig, cov leeg nqaij tawv, thiab cov leeg ua pa. Tawb tus neeg tuag tes tuag taw yuav ua rau nyuaj nqos, thiab muaj mob hnyav, ua pa ua pa thiab txawm tsis ua pa. (3) Kev ua kom haum cardiovas kev puas tsuaj: vim muaj kev phom sij rau myocardium, nquag lossis ntau yam kev mob siab, mob siab rau kev mob siab, xws li muaj ntau yam ectopic loj heev, xws li muaj ntau yam ectopic Kev sib dhos, qhov thib ob lossis thib peb degree atrioventricular thaiv, ventricular flutter, ventricular fibrillation, thiab txawm mob plawv. 2. Lub sijhawm tsim kom muaj kev nqus tau ntau dua li ntawm 0.5 txog 4 teev, hnoos qeev yog ib qho kev mob plab, tab sis cov tshuaj kho mob me, tab sis cov tshuaj kho mob me me, tab sis cov mob plab zom mov zoo ib yam li lub rooj kho mob hauv lub qhov rooj. 3. Cov tsos mob xws li loog, qaug zog, xeev siab, thiab ntuav tuaj yeem tshwm sim tsis pub dhau 1 teev tom qab cov tawv nqaij lom los ntawm cov tawv nqaij tawv thiab tawv nqaij hlawv. Cov neeg mob uas kub hnyiab tau zoo li yuav pom cov tsos mob tshwm sim tsis pub dhau 3-6 teev, suav nrog kev mob ntsws, ua pa nyuaj, thiab ua pa tseem ceeb. Cov kev kho mob ua rau pom kuj tseem zoo ib yam li cov tsos mob ntawm lub qhov rooj, nrog cov tsos mob plab zom mov me me. Tus mob feem ntau tsis txaus ntseeg sai, thiab siab mloog yuav tsum tau them thaum ntxov.

Kev kuaj mob

Cov txheej txheem yog ua raws li keeb kwm ntawm kev kis tau rau barium sib txuas hauv kev ua pa, zom, thiab tawv nqaij mucosa. Cov chaw kho mob xws li Flaccid Nqaij Parcessyy thiab Myocardial puas yuav tshwm sim, thiab kuaj cov ntawv kuaj yuav qhia cov refractory hypokalemia, uas tuaj yeem kuaj tau. Hypokalemia yog txoj kev taug kev ntawm cov leeg ua rau muaj kev lom. Cov leeg muaj zog yuav tsum tau sib txawv los ntawm cov kab mob xws li hypokalemic periury, botulinum lom zem, peripheral neuropathy, thiab mob hlwb polyradiculitis; Cov tsos mob plab zom mov xws li xeev siab, ntuav, thiab mob plab yuav tsum tau txawv los ntawm kev lom; Hypokalemia yuav tsum sib txawv los ntawm cov kab mob xws li kev sim siab, cov kev ua kom muaj kev ua kom tuag tes tuag taw, thiab Aldosteronism; Arrhythmia yuav tsum sib txawv los ntawm cov kab mob xws li cov kab mob digital thiab kab mob hauv plawv.

Lub hauv paus ntsiab lus ntawm kev kho mob:

1. Rau cov neeg uas tuaj ntsib cov tawv nqaij thiab cov yeeb yaj kiab uas tau ntxuav kom huv si nrog nqus dej kom tsis txhob muaj pa ntawm barium. Cov neeg mob hlawv yuav tsum tau kho nrog tshuaj hlawv thiab muab 2% rau 5% sodium sulfate rau lub qhov txhab ntawm lub qhov txhab; Cov neeg uas nqus tau cov pa tawm hauv lub xaib tam sim ntawd yuav tsum tau tawm ntawm qhov chaw lom thiab noj lub qhov ncauj kom huv si, thiab nqa tus nqi tsim nyog sulium; Rau cov neeg uas tau so los ntawm kev zom zaub mov, lawv yuav tsum xub ntxuav lawv lub plab nrog 2% mus rau 5% rau cov dej ntawm 20-30 g ntawm sodium sulfate rau zawv plab. 2. Detoxification Yeeb Tshuaj Sulfate tuaj yeem tsim Insoluble Barium Barium sulfate nrog barium ions los detoxify. Thawj qhov kev xaiv yog kom txhaj 10% los ntawm 10% sodium sulfate sulfate intravenously, lossis 500mL ntawm 5% sodium sulfate intravenously. Nyob ntawm tus mob, nws tuaj yeem rov qab siv dua. Yog tias tsis muaj sodium sulfate tshwj tseg, sodium thiosulfate tuaj yeem siv tau. Tom qab tsim ntawm insoluble barium barium sulfate, nws tau tawm los ntawm ob lub raum thiab yuav tsum tau siv cov kua dej hloov thiab diuresis los tiv thaiv lub raum. 3. Lub sijhawm kho ntawm hypokalemia yog tus yuam sij rau cawm neeg lub cev tuag tes tuag taw los ntawm Barium lom. Lub hauv paus ntsiab lus ntawm cov poov tshuaj ntxiv yog los muab cov poov tshuaj kom txaus mus txog electrocardoriogram rov qab li qub. Kev lom tau mis me me feem ntau yog tswj hwm qhov ncauj lus, nrog 30-60ml ntawm 10% potassium chloride muaj txhua hnub hauv kev faib cov koob tshuaj; Nruab nrab rau cov neeg mob hnyav yuav tsum tau txhawb tshuaj potassium ntxiv. Cov neeg mob uas lom feem ntau muaj kev ua siab ntev rau cov poov tshuaj ntau dua rau cov tshuaj pleev ib ce ntau dua nrog 500ml ntawm lub cev muaj zog lossis roj hmab. Cov neeg mob hnyav tuaj yeem nce cov kev xav ntawm cov tshuaj pleev cov poov xab txhaws tshuaj rau 0.5% ~ 1.0%, thiab cov tshuaj ntsuam tshuaj potassium tuaj yeem ncav cuag 1.0 ~ 1.5g toj ib teev. Cov neeg mob tseem ceeb feem ntau yuav tsum muaj kev tsis txaus siab cov koob tshuaj thiab nrawm tshaj tshuaj Cov nruj Electrocardiogram thiab cov ntshav soj ntsuam yuav tsum tau ua thaum txhawb cov potassium, thiab saib xyuas yuav tsum tau them nyiaj rau tso zis thiab lub txim ua haujlwm. 4. Txhawm rau tswj lub xub ntiag, cov tshuaj xws li Cardiolipin, Bradology, Verapamil, lossis Lidocaine tuaj yeem siv rau kev kho raws li lub arrhythmia. Rau cov neeg mob uas tsis paub keeb kwm kev kho mob thiab cov potassium hluav taws xob hloov pauv, ntshav yuav tsum tau kuaj tam sim ntawd. Tsuas txhawb cov poov tshuaj feem ntau tsis muaj txiaj ntsig thaum tsis muaj magnesium, thiab saib xyuas yuav tsum tau them rau cov magnesium rau tib lub sijhawm. 5. Txhua yam cua sov cov leeg ua pa tej pa tuag tes tuag taw yog qhov tseem ceeb ua rau muaj kev tuag hauv Barium lom. Thaum cov leeg ua pa ntawm cov neeg tuag tes tuag taw thiab cov cua tshuab hluav taws xob yuav tsum ua tam sim ntawd, thiab muaj qhov tsim nyog. 6. Kev tshawb fawb qhia tias cov ntshav huv si kev ntsuas xws li Hemodialysis muaj peev xwm ua kom nrawm dua ntawm barium ions los ntawm cov ntshav thiab muaj qee yam muaj nuj nqis. 7. Lwm cov kev kho mob uas txhawb nqa rau kev ntuav ua kom loj thiab raws plab yuav tsum tau muab cov kua dej thiab tiv thaiv kom tsis txhob sib npaug.
