Coagulation necrosis: incazelo, izimbangela kanye nokwelashwa

Necrosis kuyinto inqubo okungenakuhlehliswa lokubhubhisa yokufa kwamangqamuzana engokwemvelo kwezitho zomzimba, okuyinto kubangelwa ukuchayeka namagciwane abangela izifo. Isizathu sokuthuthukiswa kungaba: ukuchayeka okushisa aphakeme (for ukusha), izinto ezithwala izifo noma amakhemikhali, umonakalo lokukhanda. Necrosis kungaba coagulation (dry) noma kollikvatsionny (ezimanzi). Esihlokweni sihlolisise izimbangela necrosis ezomile, kanye izindlela zokwelapha ke.

Kuyini coagulation necrosis

necrosis Dry ngokuvamile kuthinta izitho ocebile amaprotheni, kodwa ongaphakeme okuqukethwe ketshezi. Lezi zihlanganisa:

• izinso;
• nezindlala adrenal;
• ubende;
• myocardium.

Dieback emizimbeni amaseli kwenzeka ngenxa enganele ukugeleza kwegazi futhi oxygenation ngenxa ezishisayo, amakhemikhali, kusetshenziswa imishini, ngokwenza umonakalo anobuthi. Ngenxa yalokho, amangqamuzana afile wome, futhi kukhona inqubo mummification. amangqamuzana afile umahluko kusuka ophilayo umugqa ecacile.

Izimbangela necrosis ezomile

kwakhiwa necrosis Dry is endabeni:

• iziyaluyalu kwegazi iphutha ukucubungula ethize target isitho indawo, owasungula ngenxa ukuntuleka komoya-mpilo nezakhi ezibalulekile;
• isifo yanda kancane kancane;
• izindawo izitho abathintekayo azange abe ketshezi ngokwanele (okunamafutha izicubu, imisipha izicubu);
• amaseli endaweni ethintekile akukho amagciwane abangela izifo.

Kutfutfukiswa necrosis ezomile bethambekele ekubeni abantu abanesimiso somzimba sokuzivikela esiqinile kanye nokungondleki.

Coagulation necrosis: mshini ukuthuthukiswa

Ngoba amangqamuzana oxygenation enganele neziyaluyalu kwegazi inqubo coagulation nasekubekweni uphawu protoplasm, endaweni ethintekile ngaphezulu seyomile. izingxenye ezilimele nethonya anobuthi phezu ezicutshini ezincikene nawo ophilayo.

Le ndawo ethintekile has a ukubukeka ehlukile: amaseli ecacile efile umugqa contoured futhi ube evelele ophuzi-grey noma ubumba-yellow umbala. Le ndawo ohlangene ne isikhathi. Esigabeni ke kuyabonakala ukuthi izicubu eyomile ngokuphelele, abe ukungaguquguquki nokunjengoshizi, kanye nephethini usongene. Ngenxa Ngokuwa kuyi-nucleus yengqamuzana ibukeke mass cytoplasm homogenous. Ngaphezu kwalokho, phakathi ukuthuthukiswa necrosis nokuvuvukala kungabonwa efile izicubu ukwenqatshwa. Uma lesi sifo sihlasela indlebe noma ithambo lomuntu, kwakheka fistula is. Nokho, lo mshini coagulation necrosis lingacaci yize kunjalo ngokugcwele.

Okunhlobonhlobo coagulation necrosis

Coagulation necrosis kuhlanganisa izinhlobo eziningana:

• Senhliziyo - owande kakhulu. Kutfutfukisa ngenxa yenhliziyo Umthambo isifo. Akukona ukuthuthukisa ku izicubu ingqondo. Lapho khona zokushaywa inhliziyo ingaba ukuvuselelwa ephelele izicubu ezonakele.
• Waxy (Zenker sika) - kubangelwa izilonda ezinzima ezithathelwanayo. Lesi sifo kwemisipha izicubu, ngokuvamile okuholela imisipha ethangeni kanye anterior udonga besisu. Ukuthuthukiswa necrosis avuse ngaphambilini sidluliselwe izifo ezifana typhus noma i-typhoid fever. ezindaweni ezithintekile kukhona grey.
• necrosis Cheesy - uhlobo oluthile lesi sifo. Sputnik sofuba, ugcunsula, uchoko, uchoko, izifo Wegener. Nge lolu hlobo ukufa necrotic kwenzeka parenchyma futhi stroma (zemicu amaseli). Isici yalesi sifo ukuthi ngaphandle nezimagqabhagqabha ezomile, kwakhiwa pasty nokunjengoshizi noma granulomas. Izicubu abathintekayo amehlo enombala ogqamile. necrosis Cheesy - omunye eziyingozi kakhulu ngenxa yokuthi ukuthi uyakwazi "ukubulala" izingxenye omkhulu.
• Fibrinoid - ubulwelwe lapho umonakalo ezicutshini. Necrosis okwenzeka ngenxa yezifo sokuhlasela kwamasosha omzimba ezifana lupus noma i-rheumatoid arthritis. Lesi sifo kakhulu kunazo kuthinta imisipha bushelelezi yegazi yemisipha. necrosis Fibrinoid libhekene ushintsho esimweni esejwayelekile collagen futhi ukuqongelela izinto necrotic. luhlolo ezincane of izicubu abathintekayo zifana fibrin. Kulokhu, labafile umbala pink. Izindawo ehlaselwe necrosis fibrinoid, aqukethe semali immunoglobulin, kanye imikhiqizo ukubola fibrin collagen.
• Fat - Imiphumela isifo ngenxa yokulimala kanye haemorrhage, kanye ukubhujiswa kwezicubu yegilo. Necrosis kuthinta esiswini amabele.
• Gangrenous - kungenzeka ezomile, igesi olumanzi. Bedsores ezigulini ngisembhedeni futhi zisebenza lolu hlobo necrosis. Ngokuvamile, ukubukeka kwalesi sifo neqhaza amagciwane engena ezindaweni ezithintekile.

esibhibhayo Dry njengoba oluthile coagulation necrosis

esibhibhayo Dry - ubulwelwe lapho isikhumba necrosis eba nabo imvelo bangaphandle. Njengomthetho, ekuthuthukiseni izifo kwanoma iyiphi nezilwanyana ezincane azisetshenziswa. esibhibhayo Dry ngokuvamile kuthinta nasemilenzeni. kwezicubu ezilimele abe nombala onsundu acishe black, futhi nentaba okuchaza ngokucacile. Izinguquko umbala ngaphansi kwethonya-hydrogen sulfide. Lokhu kwenzeka ngoba zombala-hemoglobin kuthiwa ibe insimbi sulfide. esibhibhayo Dry eba kule mibandela elandelayo:

• Lapho lwemithambo thrombosis kanye isifo sokuqina kwemithambo yegazi wemikhawulo.
• Lapho wadalula esitho lokushisa eliphezulu kakhulu noma eliphansi (i ukusha noma frostbite).
• With ukuthuthukiswa isifo Raynaud sika.
• Ephambi kwezinduna izifo, ezifana yesifo sezintwala.

Ukwelashwa Kwenziwa kuphela ukususwa kuhlinzwa kwezicubu efile.

esibhibhayo ezimanzi

esibhibhayo Wet - isifo esakheka nabo kwegciwane nezicubu ezilimele. Lesi sifo izitho ocebile umswakama, singenzeka esikhumbeni, kodwa ngokuvamile lasakazekela izitho zangaphakathi. esibhibhayo Wet kuthinta amathumbu (nge isimiso kwemithambo yegazi) futhi amaphaphu (pneumonia kwenzeka njengoba phetho).

Ngokuvamile, isifo kwenzeka ezinganeni ngoba amasosha omzimba wabo lapho yokuxhuma ukutheleleka oluthambile ngaphezulu ifomu esibhibhayo. Ukunqotshwa wadalula izicubu zomzimba ezithambile ka izihlathi kanye perineum. Lesi sifo okuthiwa umdlavuza amanzi. ezindaweni ezithintekile kukhona evuvukele kakhulu futhi ube nombala omnyama. Ayikho demarcates circuit ukuze isifo kunzima amenable ekwelashweni kuhlinzwa, ngoba kunzima ukunquma lapho ukuphela emisipheni abathintekayo. izindawo Gangrenous abe iphunga kubuhlungu ngempela, lesi sifo singumbulali luvame ukubulala.

Negesi esibhibhayo futhi decubitus

Negesi esibhibhayo obubonakala ngendlela efana manzi, kodwa ngenxa yezizathu ezahlukene. Lolu hlobo esibhibhayo eba uma usuqala ethintekile izicubu necrosis uthole amagciwane zinhlobo perfringens Clostridium, futhi ngenkuthalo ziyanda. Ama-bacterium kukho konke ukuphila kwakhe ahlukaniswe igesi othize, lapho kutholwa ezicutshini onesifo. Nokufa kule isifo kakhulu.

Ingcindezi Izilonda ungomunye izinhlobo esibhibhayo, lapho inqubo izindwangu befa. Izifo babonakala bethambekele kakhulu iziguli recumbent, izindawo njengoba ethile yomzimba kusukela immobilization isikhathi eside ngaphansi kwengcindezi futhi ungatholi izinto ezidingekayo ngegazi. Umphumela ukufa kwamangqamuzana esikhumba. Ukunqotshwa kwe-ndawo wadalula iningi sacrum, izithende, ithanga nesiphanga.

Ukuxilongwa coagulation necrosis

Ukuze ukuxilongwa "necrosis coagulative", uma umonakalo amane akhe phezulu, udokotela kwanele ukuthatha igazi kanye ezilimele izicubu isampula ukuhlaziywa.

Uma kukhona izinsolo necrosis kwezitho, Kuyinhlolo-vo eyenziwa ethé xaxa. Ukuze wenze lokhu:

• Ukwenza-X ray. Lolu cwaningo kubalulekile ikakhulukazi uma kukhona izinsolo igesi esibhibhayo.
• Ukwenza ucwaningo radioisotope. Inikezwa, uma X-ray abonisa ukuthi akukho shintsho (ngesikhathi sokuqala isifo). Umzimba womuntu injected Radioactive. Uma kukhona ushintsho kwezicubu necrotic yomzimba, ke kuzobekwa obala endaweni emnyama.
• Ukwenza CT. It wenziwa uma kukhona izinsolo ithambo izilonda.
• I-MRI. Indlela ephumelela kunazo zonke ucwaningo kanye ngisho izinguquko ezincane ezihlobene kahle kwegazi.

yezinkinga necrosis

Necrosis iyona "ukufa" kwezitho ezilimele nezicubu. Ngakho-ke zinhlobo yayo ezahlukene, njengokushaya kwenhliziyo, kwengqondo necrosis, izinso kanye isibindi, kungaphumela ekufeni yomuntu.

necrosis Olubanzi kungaholela eziyingozi, ezifana bedsores amaningi okunamathiselwe kungenzeka izifo eziyingozi. izicubu Dead isehlane e imikhiqizo yayo ukubola komzimba, ngaleyo ndlela zaholela nezinkinga anobuthi. Ngisho amafomu onomoya omnene lesi sifo kungaholela nemiphumela ebuhlungu, ezifana nezibazi esivimba amanzi kanye kumiswa izinhlumba ebuchosheni.

ukwelashwa necrosis

Ukwelashwa necrosis Ithoma ngokuhlathulula uhlobo lwayo, zadala khona umonakalo nekuhlolana ukuhlonza izifo ezihlobene.

Lapho sitholakele "ezomile isikhumba necrosis" inikezwa ekwelapheni ngezihloko ezihlukene:

• Ukwelashwa nokuvikelwa ezindaweni ezithintekile Zelenko.
• Uhlanza ebusweni isikhumba usebenzisa antiseptics.
• Bandaging necebo "Chlorhexidine".

Iziguli zanikezelwa lokwelashwa kuhlinzwa ukubuyisela evamile kwegazi, kuhlanganise nalezo abaningi babephephile ezindaweni ezithintekile. ukuhlinzwa nge resection ka ezindaweni ezithintekile AIM ngokuvamile kakhulu eyenziwa ukususa ngokusebenzisa amangqamuzana esikhumba somuntu ofile. ukunqunywa wenziwa ukuvikela izingxenye enempilo we ukusabalala kwesifo.

necrosis Dry of kwezitho zangaphakathi ziphathwe ejenti eqeda ukuvuvukala, vasodilators, hondroprotektorov. Endabeni ukwehluleka ukwelashwa ukwelashwa kuhlinzwa.
