Dab tsi yog txoj kev kho mob zoo rau kev ua xua rau cyanide?

Sodium cyanide yog ib qho tshuaj lom heev uas ua rau muaj kev pheej hmoo loj rau kev noj qab haus huv thaum raug. Nws tuaj yeem nkag mus rau hauv lub cev los ntawm ntau txoj kev, suav nrog kev ua pa, kev kov daim tawv nqaij, lossis kev noj. Kev nkag siab txog qhov xwm txheej ntawm kev lom cyanide thiab kev kho mob kom zoo yog qhov tseem ceeb rau kev tswj hwm thiab kev rov zoo. Tsab xov xwm no lub hom phiaj yog los muab cov lus qhia ntxaws ntxaws txog kev lom Sodium cyanide , nws cov tsos mob, thiab cov kev xaiv kho mob pom zoo.

Yuav ua li cas yog Sodium Cyanide?

Sodium cyanide yog ib hom ntsev dawb uas yaj tau hauv dej uas siv feem ntau hauv cov txheej txheem kev lag luam xws li kev khawb kub thiab electroplating. Nws kuj tseem siv rau hauv qee cov txheej txheem tsim tshuaj lom neeg. Vim nws muaj tshuaj lom, sodium cyanide raug cais ua ib yam khoom txaus ntshai thiab kev raug tshuaj no tuaj yeem ua rau muaj kev mob nkeeg loj heev, suav nrog kev tuag.

Toxicity Mechanism

Cyanide ua haujlwm los ntawm inhibiting lub cev muaj peev xwm siv oxygen. Nws khi rau cytochrome c oxidase, ib qho tseem ceeb enzyme nyob rau hauv mitochondrial electron thauj saw, tiv thaiv cov hlwb los ntawm kev siv oxygen zoo. Qhov no ua rau cellular hypoxia, uas, yog tias tsis kho sai, tuaj yeem ua rau lub cev tsis ua haujlwm sai thiab tuag.

Cov tsos mob ntawm Sodium cyanide lom

Cov tsos mob ntawm sodium cyanide lom yuav tshwm sim sai thiab suav nrog:

• Kev ua pa nyuaj: ua pa nyuaj, ua pa tsis tob, lossis ua pa tsis tu ncua.

• Cov tsos mob ntawm lub paj hlwb: Mob taub hau, kiv taub hau, tsis meej pem, qaug dab peg, lossis tsis nco qab.

• Cov teebmeem ntawm lub plawv thiab cov hlab ntsha: Lub plawv dhia ceev ceev, ntshav siab qis, lossis lub plawv nres.

• Cov tsos mob ntawm txoj hnyuv: xeev siab, ntuav, lossis mob plab.

• KEV KUA MUAG NTAWM TAWV NQAIJ THIAB QHOV MUAG: Liab, kub hnyiab lossis kub hnyiab thaum kov.

Tam sim ntawd teb rau Cyanide Poisoning

Yog tias xav tias muaj tshuaj lom sodium cyanide, yuav tsum tau ua tam sim ntawd. Nov yog cov kauj ruam ua raws li:

1. Tshem cov neeg mob ntawm qhov chaw uas muaj kev phom sij: Tshem cov neeg mob sai sai ntawm qhov chaw muaj kev phom sij kom tiv thaiv kev raug mob ntxiv.

2. KEV TSHUAJ KOM TSIS MUAJ KUA MUAG: Yog tias tus neeg mob tau kov cov tshuaj sodium cyanide los ntawm daim tawv nqaij lossis qhov muag, tshem tawm tag nrho cov khaub ncaws uas muaj kuab lom thiab yaug qhov chaw uas muaj kuab lom nrog dej ntau lossis dej ntsev tsawg kawg 5 feeb. Nco ntsoov tiv thaiv koj ob lub qhov muag thaum lub sijhawm no.

3. Kev ntxuav plab: Yog tias noj sodium cyanide, yuav tsum ntxuav plab nrog cov tshuaj oxidant (xws li 5% sodium thiosulfate lossis 0.02% potassium permanganate). Yuav tsum ntxuav plab sai li sai tau kom txo qhov nqus tau.

4. Kev Saib Xyuas Txhawb Nqa: Yog tias tus neeg mob ua pa tsis tob lossis tsis ua pa lawm, muab cov tshuaj txhawb kev ua pa lossis kev ua pa dag tam sim ntawd.

Tshuaj kho mob ntawm cov tshuaj lom cyanide

Thaum tus neeg mob tau ruaj khov, cov tshuaj tshwj xeeb tuaj yeem siv los tiv thaiv cov teebmeem ntawm cyanide:

1. Amyl nitrite: Muab ib lub tshuaj amyl nitrite tsoo rau hauv ib daim phuam so tes thiab kom tus neeg mob nqus cov pa tshuaj. Qhov no yog ib yam tshuaj tua kab mob sai uas hloov hemoglobin mus ua methemoglobin, uas khi rau cyanide thiab txo nws cov tshuaj lom.

2. Sodium nitrite: Sodium nitrite yaj rau hauv cov kua qabzib, qhov koob tshuaj yog 6-12 mg/kg, txhaj rau hauv cov hlab ntshav. Kev txhaj tshuaj yuav tsum qeeb qeeb, tsis pub tsawg dua 10 feeb. Saib xyuas tus neeg mob cov ntshav siab, vim tias sodium nitrite tuaj yeem ua rau hypotension. Yog tias cov ntshav siab poob qis heev, yuav tsum tsis txhob noj tshuaj.

3. Sodium Thiosulfate: Tom qab txhaj tshuaj Sodium nitrite , 50% sodium thiosulfate raug txhaj rau tib qho nqi. Cov tshuaj no ua haujlwm ua tus pub sulfur, pab txhawb kev hloov pauv ntawm cyanide mus rau thiocyanate, uas tsis muaj tshuaj lom thiab tuaj yeem tso tawm los ntawm lub raum. Yog tias tsim nyog, ib nrab lossis tag nrho cov tshuaj tuaj yeem rov ua dua ib teev tom qab.

4. Kev Soj Ntsuam: Rau cov neeg mob uas raug tshuaj lom me ntsis, tsuas yog sodium thiosulfate xwb twb txaus lawm. Tom qab kho thawj zaug, yuav tsum tau saib xyuas tus neeg mob li 2 txog 3 hnub kom paub tseeb tias cov tsos mob tsis rov tshwm sim dua.

Cov Lus Tseem Ceeb

• Kev Pheej Hmoo Thaum Noj Tshuaj Ntau Dhau: Ob qho tib si sodium nitrite thiab sodium thiosulfate tuaj yeem ua rau muaj kev lom yog tias noj ntau dhau. Kev noj tshuaj thiab kev saib xyuas kom zoo yog qhov tseem ceeb kom tiv thaiv cov kev phiv tsis zoo.

• Kev saib xyuas mus sij hawm ntev: Tom qab theem mob lom tau tswj tau lawm, yuav tsum tau saib xyuas tus neeg mob seb puas muaj cov tsos mob lossis teeb meem uas tshwm sim qeeb. Qhov no suav nrog kev saib xyuas seb puas muaj teeb meem ntawm lub paj hlwb lossis teeb meem ua pa.

• Kev Npaj Txhij Thaum Muaj Xwm Ceev: Cov chaw kho mob yuav tsum muaj cov txheej txheem los daws teeb meem kev lom cyanide, suav nrog kev muaj cov tshuaj tua kab mob thiab cov neeg ua haujlwm tau kawm los teb rau cov xwm txheej ceev no.

nyob rau hauv xaus

Sodium cyanide lom yog ib qho kev kho mob xwm txheej ceev uas yuav tsum tau lees paub thiab kho sai. Paub txog cov tsos mob thiab cov lus teb tsim nyog tuaj yeem txhim kho cov txiaj ntsig kev kho mob rau cov neeg cuam tshuam. Los ntawm kev ua raws li cov txheej txheem kev kho mob tau tsim thiab ua kom muaj kev sib kis kom raug, cov kws kho mob tuaj yeem tswj hwm cyanide lom thiab txo nws cov txiaj ntsig uas yuav ua rau tuag taus. Nco ntsoov nco ntsoov tias nyob rau hauv cov xwm txheej uas xav tias muaj tshuaj lom, kev kho mob tam sim yog qhov tseem ceeb.
