Itheyilikanye namakhompiyutha alo
Igama lezidakamizwa ngesiShayina: Itheyili
Igama lesiNgisi:Itheyili, Ba
I-TOXCIC Mechanism: Itheyiliyinsimbi ethambile, emhlophe yesiliva emhlophe ye-alkaline yomhlaba ekhona emvelweni ngesimo se-toxic barite (Baco3) nesifunda (basso4). Ama-barium amakhompiyutha asetshenziswa kabanzi kuma-ceramics, imboni yengilazi, ama-anchies ensimbi, ama-pesticides, ukukhiqizwa kwamakhemikhali, njll. I-Barium Acetate, iBarium Nitrate, iBarium Sulfide,IBarium Oxide, iBarium Hydroxide, iBarium Stearate, njll.IbhayisiyusiCishe akuyona ingozi, futhi ubuthi bezinhlanganisela ze-barium buhlobene ne-solubity yabo. Amakhompiyutha we-Blueble Barium anobuthi kakhulu, ngenkathi ama-barium carbonate, yize acishe awokufakwa emanzini, anobuthi ngenxa ye-solubility yawo ku-hydrochloric acid ukwenza i-barium chloride. Indlela enkulu yeBarium Ion Ethatheni i-blockage ye-calcium ethembele ama-potassium ancike kumaseli ngama-barium ion, okuholela ekwandeni kwe-potanzium ye-potassium, okuholela nge-hypolemalemia; Ezinye izazi zikholelwa ukuthi ama-barium ion angadala ama-arrhythmia kanye nezimpawu zesisu ngokuvuselela ngokuqondile i-myocardium nemisipha ebushelelezi. Ukumuncwa kwe-solubleitheyiliAmakhompiyutha epheshana lesisu afana naleso se-calcium, accounting cishe ama-8% omthamo ophelele. Amathambo namazinyo amasayithi asemqoka wokubeka imali, accounting for 90% womthwalo womzimba ophelele.Itheyilikugxiliwe ngomlomo ikakhulukazi kukhululwa ngendlebe; Iningi le-barium elihlungiwe yizinso livuselelwa kabusha ngama-tubules we-renal, ngenani elincane kuphela elivela kumchamo. Ukuqedwa kwe-Half-Life of Barium cishe izinsuku ezingama-3-4. Ubuthi be-barium obukhulu buvame ukubangelwa ukufakwa kwamakhompiyutha ama-barium njengempuphu yokuvutshelwa, usawoti, ufulawa we-alkali, ufulawa, njll. Kuphinde kube nemibiko ye-barium buthishoze ama-barium. I-Occupational Barium Compact Unices ayivamile futhi itholwe ikakhulukazi ngepheshana lokuphefumula noma isikhumba esilimele kanye nolwelwesi lwama-mucous. Kuphinde kube nemibiko yobuthi ebuthi okubangelwa ukuvezwa kwe-barium stearate, imvamisa ngokuqala noma ukuqala okungamahlalakhona kanye nesikhathi esingu-1-10. Amathuluzi e-AI azothuthukisa ukusebenza kahle komsebenzi, futhiAkubonakali i-AIInsizakalo ingathuthukisa ikhwalithi yamathuluzi e-AI.
Ukwelashwa ivolumu
Umthamo onobuthi besibalo sabantu ukuthatha i-barium chloride imayelana ne-0.2-0.5g
Umthamo obulalayo wabantu abadala cishe u-0.8-1.0g
Ukubonakaliswa Kwemitholampilo: 1
.
. Ukukhubazeka kwemisipha yolimi kungadala ukugwinya ubunzima, ukuphazamiseka kokucacisa, futhi ezimweni ezinzima, ukuphefumula kwemisipha yokuphefumula kungaholela ekuphefumuleni ubunzima ngisho nasekupheleni. (3) Ukulimala kwenhliziyo noma i-degree degree atrioventricular block, i-ventricular flutter, i-ventricular fibrillation, kanye nokuboshwa kwenhliziyo. 2. Isikhathi sokufakwa kokufakwa kobuthi bokuphefumula sivame ukuguquguquka phakathi kwamahora angama-0,5 kuya kwayi-4, kubonakaliswe njengezimpawu zokucasuka okuphefumula, ukuqina kwesifuba, kepha ezinye izimpawu zemitholampilo ziyefana ubuthi bomlomo. I-3. Izimpawu ezifana nokukhubazeka, ukukhathala, isicanucanu, kanye nokuhlanza kungavela kungakapheli ihora eli-1 ngemuva kokufakwa kwesikhumba esinobuthi ngesikhumba esilimele nesikhumba kuvutha. Iziguli ezinokushiswa okubanzi zingahlakuhla ngokuzumayo izimpawu kungakapheli amahora ama-3-6, kufaka phakathi ukuquleka, ukuphefumula ubunzima, kanye nomonakalo omkhulu we-myocardial. Ukubonakaliswa kwemitholampilo nakho kuyafana nobuthi bomlomo, ngezimpawu zasematheni amancane. Isimo sivame ukuwohloka ngokushesha, futhi ukunakwa okuphezulu kufanele kukhokhwe esigabeni sokuqala.
Ukuxilonga
Izindlela zisuselwa emlandweni wokuchayeka kumakhompiyutha e-barium ephethini lokuphefumula, ipheshana lokugaya ukudla, kanye nesikhumba mucosa. Ukubonakaliswa kwemitholampilo okufana nokukhubazeka kwemisipha ye-flaccid kanye nomonakalo we-myocardial kungenzeka, futhi izivivinyo zelebhu zingakhombisa i-typolemary, ezingatholakala. I-Hypokalemia isisekelo se-pathological of ubuthi be-barium acute. Ukwehla kwamandla kwemisipha kufanele kwehlukaniswe ezifweni ezinjengezifo ezifana nokukhubazeka kwezikhathi ze-hypocalalemic, i-myasthemia gravis, i-dystrophy emsulwa, ne-peripharal neuropadiculitis; Izimpawu zesisu ezifana ne-nausea, ukugabha, kanye nezindawo zesisu kufanele zihlukaniswe ubuthi bokudla; I-Hypokalemia kufanele ihlukaniswe nezifo ezinjenge-clingyyltin ubuthi, i-metabolic alkalosis, ukukhubazeka kwezikhathi zezikhathi zomndeni, kanye ne-aldosterism eyinhloko; I-Arrhythmia kufanele yehlukaniswe nezifo ezinjengobuthi be-digitalis kanye nesifo senhliziyo ephilayo.
Isimiso Sokulashwa:
1. Kulabo abahlangana nesikhumba kanye nolwelwesi lwama-mucous ukususa izinto ezinobuthi, indawo yokuxhumana kufanele igezwe kahle ngamanzi ahlanzekile ngokushesha ukuvikela ukumuncwa okwengeziwe kwe-barium ion. Ukushiswa kweziguli kufanele kuphathwe ngokushiswa kwamakhemikhali futhi kunikezwe ama-2% kuye ku-5% we-sodium sulfate ngokugcwaliswa kwenxeba; Labo abadonsa ngepheshana lokuphefumula kufanele bashiye isayithi laso ngokushesha, hlamba umlomo wabo kaningi ukuze bahlanze umlomo wabo, futhi bathathe inani elifanele le-sodium sulfate ngomlomo; Kulabo abangena ngepheshana lokugaya ukudla, kufanele baqale bageze isisu sabo nge-2% kuya ku-5% i-sodium sulfate solution noma amanzi, bese bephatha i-20-30 g ye-sodium sulfate yohudo. 2 Ukukhetha kokuqala ukujova i-10-20ml ye-10% ye-sodium sulfate intravenounously, noma i-500ml ye-5% sodium sulfate intravenohelyly. Ngokuya ngesimo, kungasetshenziswa kabusha. Uma kungekho i-sodium sulfate reserve, i-soosulfate ye-sodium ingasetshenziswa. Ngemuva kokwakheka kwe-insoluble barium sulfate, kukhishwa izinso futhi kudinga ukushintshwa koketshezi okuthuthukisiwe kanye ne-diuseris ukuvikela izinso. 3. Ukulungiswa ngesikhathi kwe-hypokolemaa kuyisihluthulelo sokutakula kanzima kwe-Cardiac Arrhythmia nokukhubazeka kwemisipha yokuphefumula okubangelwa ubuthi be-barium. Umgomo we-potassium supplevation ukuhlinzeka nge-potassium eyanele kuze kube yilapho i-electrocardiogram ibuyela kokujwayelekile. Ubuthi obumnene bungahanjiswa ngokujwayelekile, nge-30-60ml ye-10% ye-potassium chloride etholakala nsuku zonke emithanjeni ehlukene phakathi; Okuphakathi neziguli ezinzima zidinga ukungenisa okungeziwe kwe-potaskuum. Iziguli ezinalolu hlobo lobuthi ubuthi ngokuvamile zinokubekezelela okuphezulu kwe-potassium, kanye ne-10ml ye-10% chloride ingafakwa ngaphakathi nge-500ml ye-saline noma i-glucose solution. Iziguli ezinamandla zingakhuphula ukufinyeleleka kwe-potassium chloride ukumnika okungaphakathi kwe-intruvenusion ku-0.5% ~ 1.0%, kanye ne-potassium apprementation rate angafinyelela ku-1.0 ~ 1.5g ngehora. Iziguli ezibucayi zivame ukudinga imithamo engajwayelekile kanye ne-rapid potassium engezansi ngaphansi kokuqapha nge-electrocardiographic. I-Electrocardiogram eqinile kanye ne-Potassium Ukuqapha kufanele kwenziwe lapho kwenziwa i-potassium, futhi ukunakwa kufanele kukhokhwe ekuchameni kanye nomsebenzi we-renal. I-4 Ezigulini ezinomlando wezokwelapha ongaziwa kanye nezinguquko ze-leagnassium electrocardium, i-potassium yegazi kufanele ihlolwe ngokushesha. Mane nje ungeze i-potassium imvamisa ayisebenzi lapho entula i-magnesium, futhi ukunakwa kufanele kukhokhwe ukuze kwenziwe i-magnesium ngasikhathi sinye. I-5. Ukuphefumula umoya wokuphefumula komshini kukhubazeka kuyisizathu esiyinhloko sokufa ku-barium ubuthi. Lapho ukuphefumula kwemisipha yokuphefumula kuvela, i-endotracheal igubula kanye nomoya omncane wokulungiselela kufanele kwenziwe ngokushesha, futhi i-tracheotomy ingahle idingeke. I-6. Ucwaningo lubonisa ukuthi izindlela zokuhlanza igazi ezinjenge-hemodialysis zingasheshisa ukususwa kwama-barium ion kusuka egazini futhi kube nenani elithile lokwelapha. 7. Ezinye izindlela zokwesekwa ezibonakalayo zokuhlanza kanzima kanye neziguli zesifo sohudo kufanele zifakwe ngokushesha ngoketshezi ukuze kugcinwe ibhalansi yamanzi kanye ne-electrolyte futhi kuvikele izifo zesibili.
