Mankhwala othandizira poyizoni wa sodium cyanide

Sodium cyanide ndi chinthu chakupha kwambiri chomwe chingawononge kwambiri zamoyo komanso nthaka. Ikakhudzana ndi madzi, imatulutsa mpweya wa hydrogen cyanide woopsa kwambiri. Kumvetsetsa momwe mungachitire ngati munthu wadya mwangozi ndikofunikira kwambiri. Nkhaniyi ikufuna kufotokoza za mankhwala oletsa poizoni wa Sodium Cyanide.

I. Chithandizo Chadzidzidzi cha Poizoni wa Sodium Cyanide

1.Kubaya Mtsempha

• Ngati pali poizoni wa sodium cyanide , chimodzi mwa zinthu zofunika kwambiri ndikupereka 10 - 15 ml ya 3% sodium nitrite, yomwe imalowetsedwa pang'onopang'ono m'mitsempha mu yankho la 40 - ml la 25% shuga. Jakisoniyu amathandiza kusintha hemoglobin kukhala methemoglobin, yomwe imatha kumangirira ku ma ayoni a cyanide, kuchepetsa poizoni wawo.

• Nthawi yomweyo mutatha kubayidwa sodium nitrite, 25 - 50 ml ya 50% Sodium Thiosulfate iyenera kubayidwa pang'onopang'ono m'mitsempha pamalo omwewo pogwiritsa ntchito singano yomweyo. Sodium thiosulfate imakumana ndi cyanide - methemoglobin complex, ndikupanga thiocyanate yopanda poizoni, yomwe imatha kutulutsidwa m'thupi.

2.Gastric Lavage ndi Oral Administration

• Ngati mwameza Sodium cyanide , muyenera kutsuka m'mimba mwachangu. 10% sodium thiosulfate solution kapena 1:2000 potassium permanganate solution ingagwiritsidwe ntchito potsuka m'mimba. Mukatsuka m'mimba, ferrous sulfate solution yokwanira ingaperekedwe pakamwa. Ferrous sulfate imatha kuchitapo kanthu ndi ma cyanide ions m'mimba ndikupanga ferrous cyanide yosasungunuka, zomwe zimachepetsa kuyamwa kwa cyanide.

II. Njira ndi Kuopsa kwa Poizoni

1.Njira za Poizoni

• Poizoni zimachitika makamaka pokoka mpweya wa fumbi lake kapena mpweya wa hydrogen cyanide. Kukoka mpweya wa sodium cyanide kapena mpweya wa hydrogen cyanide kungayambitse zotsatira zoopsa. Akakowedwa, zinthu zapoizonizo zimatha kulowa mwachangu m'magazi kudzera mu alveoli m'mapapo.

• Imathanso kuyamwa kudzera pakhungu ndi m'mimba. Khungu likakumana ndi fumbi la sodium cyanide kapena mankhwala, mankhwalawa amatha kulowa m'zigawo za khungu ndikulowa m'magazi. Kulowetsedwa kudzera m'mimba kumapangitsa kuti cyanide itengedwe mwachindunji kuchokera m'mimba ndi m'matumbo.

2.Kuopsa kwa Poizoni

• Kumwa pakamwa kwa 0.06 g ya Hydrocyanic Acid kapena 0.1 - 0.3 g ya sodium cyanide kumatha kupha anthu. Ngati munthu akumwa kwambiri kapena kupuma, hydrocyanic acid yochuluka imatha kuyambitsa kupuma komanso mtima kulephera kugwira ntchito.

• Kwa iwo omwe amakoka fumbi la sodium cyanide kapena mpweya wa hydrogen cyanide, kuchotsedwa mwamsanga pamalo oipitsidwa kupita kumalo omwe ali ndi mpweya wabwino ndikofunikira, ndikutsatiridwa ndi makonzedwe a antidotes. Zikavuta kwambiri pamene wovulalayo wasiya kupuma ndi kugunda kwa mtima, kutsitsimula mtima kwa mtima ndi kupuma (CPR) kuyenera kuchitidwa mwamsanga.

• Pamene thupi laipitsidwa ndi fumbi la sodium cyanide kapena litawazidwa ndi sodium cyanide solution, zovala zoipitsidwazo ziyenera kuchotsedwa mwamsanga, ndipo khungu liyenera kutsukidwa bwinobwino ndi madzi aukhondo. Pakawotcha khungu, malo okhudzidwawo amatha kutsukidwa ndi 3% boric acid solution.

Pomaliza, poyizoni wa sodium cyanide ndi moyo wowopsa. Kudziwa mankhwala oyenera komanso njira zoyankhira mwadzidzidzi n'kofunika kwambiri kuti tipulumutse miyoyo ndi kuchepetsa kuwonongeka komwe kumachitika chifukwa cha poizoniyu. Ndikofunikiranso kudziwitsa anthu za kuopsa kwa sodium cyanide ndikuwonetsetsa kuti chitetezo chilipo m'malo omwe angakhalepo.
