Coagulation necrosis: tsananguro, zvinokonzera uye kurapwa

Necrosis chinhu kusingarapiki muitiro nokuparadzwa uye sero rufu kwevanhu zvomukati, izvo zviri kukonzerwa yokuwana pathogenic utachiona. Chikonzero pokumuka kunogona: kugara kumusoro tembiricha (nokuti kutsva), chirwere kana makemikari vamiririri, zvokuimba kukuvara. Necrosis zvinogona coagulation (mufushwa) kana kollikvatsionny (nyoro). Munyaya tikanyatsoongorora zvinokonzera akaoma necrosis, uyewo nzira yokurapa nayo.

Chii coagulation necrosis

Kazhinji Dry necrosis kunokanganisa nhengo akapfuma mapuroteni, asi pasi zvokunwa kugutsikana. Idzi dzinosanganisira:

• itsvo;
• ari adrenal mumasero;
• chirwatata;
• myocardium.

Dieback miviri masero kunoitika nokuda ropa kuyerera kukwana uye oxygenation somugumisiro chafariz, makemikari, zvemaziso, muchetura kukuvara. Somugumisiro, masero akafa kuoma, uye pane chirongwa pakuomesa zvitunha. Masero vakafa kusiyaniswa kurarama mutsetse yakajeka.

Zvinokonzera akaoma necrosis

Dry necrosis achiumbwa nyaya:

• kweropa zvirwere yakaitika kubata zvakananga chipfuro nhengo nzvimbo, yakatanga somugumisiro okisijeni kushaikwa uye zvinokosha muviri;
• chirwere yakatanga zvishoma nezvishoma;
• nzvimbo nhengo sei asina mvura zvakakwana (mafuta rinenge tsandanyama tishu);
• masero Munzvimbo hapana pathogenic tupukanana.

Development akaoma necrosis vari tichikurumidza vanhu vane simba zvirwere uye kushaya zvokudya zvinovaka muviri.

Coagulation necrosis: kuti mashandiro okukura

Nokuti masero kukwana oxygenation uye kweropa kusagadzikana nedanho coagulation uye kuiswa chisimbiso protoplasm, zvikuru njodzi nharaunda unoomesa. Dzaparadzwa zvikamu zvine chepfu zvainoita pedyo mupenyu munyama.

Munzvimbo iyi ine nevamwe chitarisiko: masero yakajeka akafa contoured mutsetse uye vane raidudzwa yero-ndachena kana nevhu-yellow ruvara. Nzvimbo iri nekuumbanidzwa pamwe nguva. Muchikamu chinogona kuonekwa kuti munyama vari yaoma, vane cheesy kusachinja-chinja, ane damerau muenzaniso. Somugumisiro pokuwa sero musimboti tarisa akafanana guru homogenous cytoplasm. Uyezve, panguva kukura necrosis uye kuzvimba zvinogona kuonekwa akafa tishu kurambwa. Kana chirwere rinokanganisa nzeve kana pfupa romunhu, mumwe fistula aumbwa. Zvisinei, kuti mashandiro ose coagulation necrosis ichiri kwete zvakazara pachena.

Siyana coagulation necrosis

Coagulation necrosis zvinosanganisira marudzi akawanda:

• Mwoyo kurwisa - vakawanda mhando. Inokudziridza nokuda coronary tsinga chirwere. Hazvina munguva uropi. Kana chemwoyo kungava patsva rakazara ukama tishu.
• Waxy (Zenker zvaJehovha) - iri kukonzerwa zvikuru rwarisa maronda. The chirwere chinobata tsandanyama rinenge kazhinji zvichiguma pahudyu tsandanyama uye Anterior abdominal rusvingo. Kukura necrosis vanotsamwisa kare Kutamiswa zvirwere zvakadai typhus kana sefivha. vawirwa nenjodzi dziri pfumbu.
• Cheesy necrosis - chaiyo mhando chirwere. Sputnik tibhii, njovhera, maperembudzi, maperembudzi, zvirwere Wegener. With kwakadai necrotic rufu kunoitika parenchyma uye stroma (fibers uye masero). The Zvinoitwa chirwere ichi kuti kunze akaoma makwapa akasvibirika, akaumba cheesy pasty kana granulomas. The zvakakanganisa munyama openya blue. Cheesy necrosis - chimwe chezvinhu ngozi nokuti iye anokwanisa "kuuraya" zvikamu zvikuru.
• Fibrinoid - chirwere umo kukuvara connective tishu. Necrosis kunoitika muna autoimmune zvirwere zvakadai lupus kana dzinonzi rheumatoid arthritis. The chirwere chinonyanya zvakasimba kunokanganisa anotsvedzerera tsandanyama midziyo ropa uye fibers. Fibrinoid necrosis kunoratidzwa nokuchinja kunowanzoitika ezvinhu collagen uye kuunganidza necrotic zvinhu. Nemaziso kuongorora kukanganiswa munyama akafanana fibrin. Panyaya iyi, vakafa rakajeka vaaleanpunainen ruvara. Areas kukanganiswa fibrinoid necrosis, ane yakawanda immunoglobulin, uyewo kuora zvibereko fibrin uye collagen.
• Mafuta - chirwere zvabuda kubva mukukuvara uye chokubuda, uyewo kuparadzwa thyroid munyama. Necrosis kunokanganisa mudumbu uye mazamu.
• Gangrenous - angava pakaoma, nyoro gasi. Bedsores Varwere akangorara kushanda kwakadai necrosis. Kakawanda, pakuonekwa chirwere kukonzera utachiona kupinda munzvimbo sei.

Dry neronda rinonyenga sezvo rudzi coagulation necrosis

Dry neronda rinonyenga - chirwere umo ganda necrosis anova neVadzidzi kwokunze kwezvakatipoteredza. Kazhinji, kukura zvirwere chero tusingaoneki kwete zvinobatanidzwa. Kazhinji Dry neronda rinonyenga kunokanganisa maoko nemakumbo. Dzaparadzwa munyama vane rima, anenge vatema ruvara, uye zvakajeka delineated gandiwa. Ruvara Kuchinja pasi pokudzora rehydrogen sulfide. Izvi zvinoitika nokuti Chizenga pigments vari dzikwanise simbi sulfide. Dry neronda rinonyenga ikabuda zvinotevera ezvinhu:

• Kana arterial thrombosis uye atherosclerosis migumo.
• Kana pachena kuti gumbo mukuru kana yakaderera tembiricha (nokuti kutsva kana frostbite).
• With kukura Raynaud chirwere.
• In pamberi kutapukirwa, zvakadai typhus.

Treatment rinoitwa chete kuvhiya kubviswa akafa tishu.

kunyorova neronda rinonyenga

Wet neronda rinonyenga - chirwere ikabuda kwaaita noutachiona mu ukama tishu. The chirwere chinobata nhengo akapfuma mwando, anogona kuitika paganda, asi kazhinji kupararira nhengo dzomukati. Wet neronda rinonyenga kunokanganisa ura (pamwe mhingaidzo pamusoro arteries) uye mumapapu (nemabayo kunoitika sezvo pamigumisiro).

Kazhinji, hosha rinowanikwa muvana nokuti kutapata vavo kana unobatanidza chirwere zvikuru nyore kufurirwa fomu neronda rinonyenga. Kukundwa akafumura nyoro zvinyama pamusoro pamatama uye perineum. The chirwere unonzi kenza mvura. vawirwa nenjodzi dziri kuzvimba chaizvo uye vane ruvara rima. No demarcates redunhu saka chirwere kwakaoma amenable kuti kuvhiya kurapwa, nekuti zvakaoma kusarudza magumo ari sei nyama. Gangrenous nzvimbo vane chisingafadzi chaizvo kwakanaka, chirwere kazhinji zvinouraya.

Gas neronda rinonyenga uye decubitus

Gas neronda rinonyenga mu kuonekwa chaizvo akafanana nyorova, asi zvakasiyana zvikonzero. Izvi mhando neronda rinonyenga hwapedyo kana kutanga njodzi zvinyama necrosis kuwana utachiona mhuka Clostridium perfringens, uye kushingaira kuwanda. Utachiona muupenyu hwake akaparadzanisa chaizvo gasi, icho dzakaonekwa mune chirwere munyama. Rufu mune chirwere ichi chaizvo.

Pressure maronda tiri mumwe mhando neronda rinonyenga, umo muitiro kufa micheka. Zvirwere asingatani varwere recumbent, sezvo dzimwe nzvimbo muviri kubva refu immobilization pasi kufurirwa uye hamugamuchiri raida zvinhu neropa. Mugumisiro rufu ganda masero. The kukundwa chezvinhu pachena nzvimbo sacrum, zvebhiza, chidya.

Chirwere kuti coagulation necrosis

Nokuti chirwere "coagulative necrosis", kana kukuvara vari zvachero, chiremba zvakakwana kutora hunenge zvinyama yokuenzanisira kuti kuongorora ropa uye.

Kana paine fungidziro pakati necrosis pakati nhengo, imwe ongororo kuitwa zvakawanda chaizvo. Kuti aite izvi,

• Kuitisa radiography. kudzidza Izvi zvinonyanya kukosha kana paine fungidziro negasi neronda rinonyenga.
• Kuitisa radioisotope kudzidza. Ko basa, kana maekisirei akaratidza hapana shanduko (munguva kutanga pavaipfuura chirwere). Muviri womunhu jekiseni radioactive fuma. Kana paine shanduko mune necrotic nyama dzomuviri, zvicharangarirwa inosimbiswa ine rima panzvimbo.
• Kuitisa CT. Voitakura kunze kana pane fungidziro repfupa maronda.
• An MRI. Nzira inonyatsobudirira kutsvakurudza uyewo kunyange kuchinja kuduku chokuita zvakanaka kweropa.

yematambudziko necrosis

Necrosis ndiye "rufu" pamusoro zvaparadzwa nhengo uye munyama. Naizvozvo dzayo dzakasiyana marudzi, zvakadai mwoyo, pfungwa necrosis, itsvo uye chiropa, zvinogona rufu wacho.

Kukuru necrosis kunogona kukonzera matambudziko akakura, akadai bedsores akawanda zvinoita kuda kutapukirwa ngozi. Dead zvinyama iri voga kwayo kuora zvibereko muviri, saka zvichitungamirira chepfu matambudziko. Kunyange munhu munyoro siyana chirwere kungaita kuti nemigumisiro, zvakadai myocardial scarring uye nokuumbwa cysts muuropi.

necrosis kurapwa

Kurapa Necrosis rinotanga tsanangudzo azvo, ivo kwakakanganisa tinyatsonzwisisa uye kuziva ukama zvirwere.

Apo chirwere kuti "akaoma ganda necrosis" riri basa kuti kukamura uchishandisa dambudziko:

• Treatment ane nzvimbo Zelenko.
• Kuchenesa ganda pamusoro uchishandisa antiseptics.
• Maronda ane mhinduro "Chlorhexidine".

Varwere vakanga dzinounzwa kuna zvokurapa uye kuvhiya kurapwa rokudzorera zvakajairika kweropa, kusanganisira vaya vari munzvimbo sei. Kuvhiya pamwe resection nharaunda sei chinangwa vanowanzobatwa akaita kubvisa ganda masero akafa. kudimurwa rinoitwa kudzivirira utano zvikamu kupararira chirwere.

Dry necrosis of zvomukati kubatwa Anti-anogumbura vamiririri, vasodilators, hondroprotektorov. In vairapwa kukundikana kuvhiya kurapwa.
