Lithini inqanaba leMpumelelo yokuNyanga iPoisoning yeSodium Cyanide?

Sodium i-cyanide sisiyobisi esiyityhefu kakhulu, kwaye Ityhefu yesodium cyanide yimeko kaxakeka esongela ubomi. Umyinge wempumelelo yonyango uchatshazelwa yimiba emininzi, kwaye akukho namnye, inani eliqinisekileyo lempumelelo elisebenza kuzo zonke iimeko.

1. Indlela enetyhefu yeSodium Cyanide

Ukukhutshwa kwe-sodium cyanide Iiyoni zecyanide (CN⁻) emzimbeni. Ezi ion zecyanide zinobudlelwane obuqine ngokugqithisileyo be-iron yeferric (Fe³⁺) kwicytochrome oxidase kwiiseli. Xa zidibene, zenza i-complex ezinzile, eyenza i-cytochrome oxidase ilahlekelwe amandla ayo okudlulisa ii-electron. Ngenxa yoko, ikhonkco lokuthutha i-electron kwiiseli liphazamisekile, kwaye iiseli azikwazi ukusebenzisa i-oksijini ngokuqhelekileyo, ekhokelela kwi-intracellular asphyxia. Izicubu zinyanzeliswa ukuba zitshintshe ukusuka kwi-aerobic metabolism ukuya kwi-anaerobic metabolism, ihamba kunye nokunyuka kwe-lactate kunye ne-inorganic phosphate umxholo kwii-tissue, kunye nokuncipha kwe-glycogen kunye ne-ATP umxholo. Ekubeni inkqubo ye-nervous central inomdla kakhulu kwi-hypoxia, iyona ngowokuqala ukonakala, ngakumbi iziko lokuphefumula kunye neziko le-vasomotor.

2. Imiba echaphazela inqanaba leMpumelelo yoNyango

2.1 Ubungqongqo betyhefu

• Ityhefu ethambileyo: Kwiimeko zobulali Isodium cyanide ukutyhefa, ukuba idosi ye-cyanide engenisiweyo okanye efuthiweyo incinci ngokwentelekiso, iindlela zembuyekezo zomzimba zisenokukwazi ukusebenza ukusa kumlinganiselo othile. Ngokomzekelo, izigulana zinokufumana kuphela iimpawu ezincinci ezifana nentloko, isiyezi, isicaphucaphu, kunye nokuphefumula okufutshane. Kwiimeko ezinjalo, ukuba unyango lunyangwe ngokukhawuleza, izinga lokuphumelela lonyango liphezulu. Ngokukhutshwa kwangethuba kumthombo wetyhefu, ukuphefumlelwa ioksijini, kunye nokusetyenziswa kwamayeza afanelekileyo okunyanga, uninzi lwezigulana zinokuchacha ngokupheleleyo.

• Ityhefu Emandla: Xa ityhefu inzima, izigulane zinokuqhubela phambili ngokukhawuleza kwiimpawu ezifana ne-coma, ukuxhuzula, kunye nokubanjwa kwentliziyo kunye nokuphefumla. Ngeli xesha, amalungu amaninzi emzimbeni wonakaliswe kakhulu. Ngokomzekelo, intliziyo inokuyeka ukubetha ngokufanelekileyo, kwaye ingqondo inokubandezeleka ngenxa ye-hypoxia enzima-ukulimala kwe-ischemic. Okukhona lo mbuso uzingisa, kokukhona umlinganiselo omkhulu wokonakala kwelungu, kwaye kokukhona kuba nzima ukubuyisela umva imeko, okukhokelela ekuncitshisweni kokuphumelela konyango.

2.2 Ixesha letyhefu

• Ityhefu yexesha elifutshane: Ukuba ixesha ukusuka ukwenzeka kwe sodium cyanide ubuthi ekuqaleni konyango lufutshane, umonakalo emzimbeni ulinganiselwe. Umzekelo, ukuba umntu uyahlangulwa kwaye aphathwe kwimizuzu embalwa ukuya kwisiqingatha seyure emva kokuphefumla okanye ukuphefumla Isodium cyanide, ithuba lonyango oluyimpumelelo liphezulu kakhulu. Ngenxa yokuba ngeli xesha, i-cyanide ayizange ibe nexesha elaneleyo lokubangela umonakalo ongenakuguqulwa kwizitho eziphambili.

• Ixesha elide Ityhefu: Njengoko ixesha lihamba, i<em>cyanide iqhubeka isebenza kwiiseli, yaye umonakalo kumalungu anjengentliziyo, ubuchopho nesibindi uyaqokelelana. Ukuba ixesha letyhefu lidlula iiyure ezininzi kwaye isigulane asifumananga unyango olusebenzayo, izinga lokusinda liya kuba liphantsi kakhulu. Ngokomzekelo, emva kweeyure eziliqela zetyhefu eyingozi yecyanide, ingqondo isenokuba necrosis ebanzi ngenxa ye<em>hypoxia, kwaye nokuba i<em>cyanide isusiwe emzimbeni kamva, umsebenzi wobuchopho owonakeleyo kunzima ukuchacha.

2.3 Ukufika ngexesha kunye nokuchaneka kwemilinganiselo yoNcedo lokuQala

• Ngexesha Lokuqala - Uncedo: Amanyathelo oncedo lokuqala akhawulezileyo kwindawo yetyhefu adlala indima ebalulekileyo. Nje ukuba kurhanelwe ityhefu ye-sodium cyanide, inyathelo lokuqala kukushenxisa isigulana ngokukhawuleza kwindawo enetyhefu ukunqanda ukuba sesichengeni ngakumbi. Ngokomzekelo, xa kukho ityhefu yokuphefumla kwingozi yeshishini, ukuhambisa isigulana kwindawo enomoya omtsha ngokukhawuleza kunokunciphisa ukuphefumla kwe-cyanide eyongezelelweyo. Kwangaxeshanye, ukubiza iinkonzo zonyango olungxamisekileyo ngokukhawuleza kubalulekile. Ukuba ukuphefumla kwesigulane okanye ukubetha kwentliziyo kuyekile, ukuvuselela i-cardiopulmonary resuscitation (CPR) kufuneka kuqaliswe ngokukhawuleza. Umzuzu ngamnye wokulibaziseka kumanyathelo oncedo lokuqala anokunciphisa izinga lokuphumelela unyango.

• Okuchanekileyo kuqala - Uncedo: Ukulungisa imisebenzi yoncedo lokuqala nayo ibalulekile. Ngokomzekelo, xa uqhuba i-CPR, kuyimfuneko ukulandela amanyathelo okusebenza achanekileyo, kubandakanywa umlinganiselo ochanekileyo wokunyanzeliswa kwesifuba kwi-respiration yokwenziwa. Ukongezelela, ukuba isigulana siye saginya i-sodium cyanide, iindlela ezingafanelekanga zokuhlambuluka zinokubangela ukulangazelela kwaye zibeke engozini ubomi bomguli. Ngoko ke, aboncedo lokuqala kufuneka baqeqeshwe ukuqinisekisa ukuba amanyathelo oncedo lokuqala aqhutywa ngokuchanekileyo.

2.4 Unyango esibhedlele

• Ukusetyenziswa kweAntidotes: Esibhedlele, ukusetyenziswa ngexesha elifanelekileyo kunye nokuchanekileyo kwe-antidotes likhonkco eliphambili kunyango lwe-sodium cyanide poisoning. Unyango oluphambili lwe-antidote yetyhefu ye-cyanide lunyango lwe "nitrite - thiosulfate". I-nitrites (efana ne-sodium nitrite) inokwenza i-oxidize inxalenye ye-hemoglobin eqhelekileyo egazini kwi-methemoglobin. I-Methemoglobin iqulethe i-iron ye-ferric (Fe³⁺), enobudlelwane obunamandla bee-ion ze-cyanide kune-cytochrome oxidase. Ke ngoko, inokukhuphisana ne-cytochrome oxidase yee-ion ze-cyanide, ibophe ii-ion ze-cyanide ukwenza i-cyanmethemoglobin, ngaloo ndlela ikhulula isiphumo sokuthintela ii-ion ze-cyanide kwi-cytochrome oxidase. Emva koko, i-thiosulfate isetyenziswa. Ngaphantsi kwesenzo se-enzyme ye-rhodanese yomzimba, i-thiosulfate isabela kunye ne-cyanide ion ukwenza i-thiocyanate engeyiyo eyityhefu, ekhutshwe emzimbeni ngomchamo. Ukuba i-antidote inokusetyenziswa kwangethuba ngokwemeko yesigulana, izinga lokuphumelela lonyango liya kuphuculwa kakhulu.

• Unyango oluBanzi: Ukongeza ekusebenziseni i-antidotes, amanyathelo onyango abanzi nawo ayafuneka. Oku kubandakanya ukugcina iimpawu ezibalulekileyo zesigulane, ezifana nokuqinisekisa ukuphefumla okuzinzile ngokusebenzisa i-ventilation yomatshini ukuba kuyimfuneko, ukugcina uxinzelelo lwegazi oluqhelekileyo ngokutshintshwa kwamanzi kunye neziyobisi ze-vasoactive, kunye nokukhusela kunye nokunyanga iingxaki ezifana ne-cerebral edema. Ngokomzekelo, ukusetyenziswa kwe-glucocorticoids, i-hypertonic glucose, kunye ne-vitamin C kunokuncedisa ukunciphisa i-cerebral edema. Ukuba la manyathelo onyango abanzi aphunyezwa ngokufanelekileyo, kuya kuba negalelo ekuphuculeni izinga lokuphumelela unyango.

3. Uqikelelo Jikelele loNyango lweMpumelelo

Ngokubanzi, ukuba ityhefu ithambile, isigulane siphathwa ngokukhawuleza (ngokuqhelekileyo kwimizuzu engama-30 ukuya kwi-1 iyure emva kokutyhefa), kwaye yonke inkqubo yonyango, kubandakanywa uncedo lokuqala kwindawo kunye nonyango lwezonyango esibhedlele, lwenziwa ngokuchanekileyo, izinga lokuphumelela unyango lunokuba luphezulu kakhulu, mhlawumbi lufikelela kuma-80% kwezinye iimeko. Noko ke, kwiimeko ezimandundu, ingakumbi abo banetyhefu ixesha elide (ngaphezu kwe-2 - 3 iiyure) kunye nonyango emva kwexesha, izinga lokuphumelela unyango unokuba ngaphantsi kwama-20%, kwaye kwezinye iimeko ezinzima kakhulu, isigulana sisenokungakwazi ukusindiswa phezu kwayo yonke imizamo.

Ekugqibeleni, izinga lokuphumelela lokunyanga i-sodium cyanide poisoning liyahluka kakhulu kuxhomekeke kwizinto ezininzi. Isitshixo sokuphucula izinga lokuphumelela silele ekuthinteleni kwangethuba, ngexesha elifanelekileyo kwaye lichanekileyo lokuqala - uncedo kwindawo yesiganeko, kunye nonyango olubanzi nolusebenzayo esibhedlele.
