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 phom sij loj rau kev noj qab haus huv thaum raug. Nws tuaj yeem nkag mus rau hauv lub cev los ntawm ntau txoj hauv kev, suav nrog kev nqus pa, kev sib cuag ntawm daim tawv nqaij, lossis kev noj tshuaj. Kev nkag siab txog qhov xwm txheej ntawm cyanide lom thiab kev kho mob tsim nyog yog qhov tseem ceeb rau kev tswj xyuas kom zoo thiab rov zoo. Kab lus no aims muab cov ncauj lus kom ntxaws txheej txheem cej luam ntawm Sodium cyanide lom, nws cov tsos mob, thiab pom zoo xaiv kev kho mob.

Yuav ua li cas yog Sodium Cyanide?

Sodium cyanide yog cov ntsev dawb, dej-soluble ntsev siv feem ntau hauv cov txheej txheem xws li kub mining thiab electroplating. Nws kuj yog siv rau hauv qee yam kev tsim tshuaj lom neeg. Vim nws toxicity, sodium cyanide raug cais raws li cov khoom siv phom sij thiab raug cuam tshuam tuaj yeem ua rau muaj mob hnyav, 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:

• Ua pa nyuaj siab: ua pa nyuaj, ua tsis taus pa, lossis nres ua pa.

• Neurological tsos mob: Mob taub hau, kiv taub hau, tsis meej pem, qaug dab peg, lossis tsis nco qab.

• Cov teebmeem ntawm lub plawv: Lub plawv dhia ceev, ntshav siab, lossis plawv nres.

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

• SKIN THIAB EYE IRRITATION: Liab, kub hnyiab los yog tshuaj lom neeg kub hnyiab thaum sib cuag.

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 los ntawm qhov chaw raug: Ceev nrooj tshem cov neeg mob los ntawm qhov chaw muaj kab mob kom tsis txhob kis tau ntxiv.

2. DECONTAMINATION: Yog tias tus neeg mob tau ntsib nrog sodium cyanide los ntawm daim tawv nqaij lossis ob lub qhov muag, tshem tawm tag nrho cov khaub ncaws tsis huv thiab yaug qhov chaw cuam tshuam nrog dej ntau los yog ntsev rau tsawg kawg 5 feeb. Nco ntsoov tiv thaiv koj ob lub qhov muag thaum tus txheej txheem no.

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

4. Kev pab txhawb nqa: Yog hais tias tus neeg mob pom qhov ntiav ntiav lossis tsis ua pa, muab cov tshuaj ua pa los yog ua pa tawm 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: Tso cov amyl nitrite capsule rau hauv ib lub phuam thiab kom tus neeg mob nqus pa. Qhov no yog cov tshuaj tua kab mob sai uas hloov hemoglobin rau hauv methemoglobin, uas khi rau cyanide thiab txo nws cov toxicity.

2. Sodium nitrite: Sodium nitrite yog yaj nyob rau hauv cov kua qab zib, koob tshuaj yog 6-12 mg / kg, txhaj tshuaj intravenously. Kev txhaj tshuaj yuav tsum tau qeeb, tsis pub tsawg tshaj 10 feeb. Ua tib zoo saib xyuas tus neeg mob ntshav siab, vim tias sodium nitrite tuaj yeem ua rau hypotension. Yog tias ntshav siab poob qis, cov tshuaj yuav tsum tau nres.

3. Sodium Thiosulfate: Tom qab lub Kev txhaj tshuaj sodium nitrite, 50% sodium thiosulfate yog txhaj ntawm tib tus nqi. Cov tshuaj no ua raws li tus neeg pub dawb, pab txhawb kev hloov pauv ntawm cyanide mus rau thiocyanate, uas tsis tshua muaj tshuaj lom thiab tuaj yeem tawm los ntawm ob lub raum. Yog tias tsim nyog, ib nrab lossis puv koob tuaj yeem rov ua dua ib teev tom qab.

4. Soj Ntsuam: Rau cov neeg mob me me, sodium thiosulfate ib leeg yuav txaus. Tom qab kev kho mob thawj zaug, tus neeg mob yuav tsum tau saib xyuas rau 2 mus rau 3 hnub kom ntseeg tau tias cov tsos mob tsis zoo.

Cov Lus Tseem Ceeb

• Overdose Risk: Ob leeg sodium nitrite thiab sodium thiosulfate tuaj yeem ua rau muaj tshuaj lom yog tias noj ntau dhau. Ua tib zoo noj tshuaj thiab saib xyuas yog qhov tseem ceeb los tiv thaiv qhov tshwm sim tsis zoo.

• Kev soj ntsuam mus sij hawm ntev: Tom qab lub sijhawm mob hnyav ntawm kev ua xua yog tswj tau, tus neeg mob yuav tsum tau saib xyuas rau cov tsos mob qeeb lossis teeb meem. Qhov no suav nrog kev saib xyuas cov teeb meem neurological lossis teeb meem ua pa.

• Kev npaj xwm txheej kub ntxhov: Cov chaw kho mob yuav tsum muaj cov txheej txheem nyob rau hauv qhov chaw los daws cov tshuaj lom cyanide, suav nrog kev muaj tshuaj tua kab mob thiab cov neeg ua haujlwm raug cob qhia los teb rau cov xwm txheej kub ntxhov.

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.
