Coagulation necrosis: inkcazelo, unobangela nonyango

Necrosis yinkqubo vuhlayiseki intshabalalo kunye ukufa kweeseli kwizigqeba zabantu, nto leyo ibangelwa sesichengeni iintsholongwane izifo. Isizathu sokuba uphuhliso ingaba: ukubekwa kumaqondo obushushu aphezulu (ngokuba ukutsha), izifo okanye imichiza, umonakalo. Necrosis ingaba coagulation (eyomileyo) okanye kollikvatsionny (emanzi). Kwinqaku sihlolisise oonobangela necrosis owomileyo, kwakunye neendlela ukuluphatha.

Yintoni na coagulation necrosis

necrosis Dry ngokuqhelekileyo ichaphazela amalungu zizityebi ngakwicala leeprothini, kodwa umxholo ulwelo ezantsi. Ezi ziquka:

• sezintso;
• amadlala adrenal;
• spleen;
• myocardium.

Dieback imizimba iiseli kwenzeka ngenxa yokumpompoza kwegazi elanele oxygenation ngenxa thermal, lwekhemikhali, mechanical, umonakalo ityhefu. Ngenxa yoko, iiseli abafileyo koma, yaye kukho inkqubo bomisa. iiseli abafileyo umahluko kusuka uphila umgca ecacileyo.

Izinto ezibangela necrosis owomileyo

necrosis Dry amiliswe ngaphakathi kwimeko:

• izifo yegazi kwenzeka ubekeko site ekujoliswe omzimba ezithile, owaphuma ngenxa ioksijini intswelo kunye nezakhi kubalulekile;
• isifo kancane kancane;
• iindawo zomzimba ezichaphazelekayo akazange abe ulwelo ngokwaneleyo (okunamafutha izihlunu, izihlunu zomzimba);
• eseli kwi ariya ochaphazelekayo akukho iintsholongwane izifo.

Uphuhliso necrosis owomileyo ezisengozini kakhulu kubantu abanamajoni mzimba kunye nokungondleki.

Coagulation necrosis: indlela yophuhliso

Kungenxa yokuba iiseli oxygenation ayoneli kunye nokuphazamiseka yegazi kwinkqubo coagulation nokutywinwa protoplasm, kummandla ochaphazelekayo kakhulu yome. ezonakeleyo zibe nefuthe yityhefu kwi ancedisana abahlala eduze.

Le ndawo ochaphazelekayo uba imbonakalo hlukile: iiseli ecacileyo abafileyo umgca ulinywa yaye mthubi-ngwevu okanye ngodongwe-yellow umbala ngokukhawuleza. Le ndawo uyagangatheka kunye nexesha. Kwicandelo kunokuthi kubonwe ukuba izihlunu ezo zomile ngokupheleleyo, abe kane obufana, onepateni ungapheleli. Ngenxa ekuweni yeseli isiqalo ekhangeleka ngobuninzi kukho icytoplasm homogenous. Ngaphezu koko, ngexesha uphuhliso necrosis kunye nokudumba kunokubonwa ufile ijwabu ukwaliwa. Ukuba sifo sichaphazela endlebeni nokuba lithambo lomntu, a fistula kwakheka. Nangona kunjalo, indlela ye coagulation necrosis ayide icace ngokupheleleyo.

Ezahlukahlukeneyo coagulation necrosis

Coagulation necrosis iquka iintlobo ezininzi:

• senhliziyo - uhlobo ixhaphakileyo. Yenzeka ngenxa kwemithambo. Akunamsebenzi zokuphuhlisa ijwabu ebuchotsheni. Xa isifo sentliziyo inokuba ngokutsha olupheleleyo esikule yonakele.
• Angwevu, anencindi (Zenker kaThixo) - ibangelwa izibhaxu esosulelayo. Esi sifo sichaphazela izihlunu imisipha, ngokufuthi neziphumo izihlunu ethangeni kunye nodonga sobuKristu esiswini. Uphuhliso necrosis axhokonxe ngaphambili kugqithiselwa izifo ezifana yesifo okanye yicesina. kwimimandla echaphazelekayo are hina.
• necrosis obufana - uhlobo oluthile kwesi sifo. Zwi isifo sephepha, negcushuwa, iqhenqa, iqhenqa, izifo Wegener. Nale hlobo kufa necrotic lwenzeka parenchyma kunye stroma (okuzenzela kunye iiseli). Olona phawu kwesi sifo ukuba ngaphandle amabala ezomileyo, eyakhiwe pasty obufana okanye granulomas. Ancedisana nale pink eliqaqambileyo. necrosis obufana - enye kuyingozi kakhulu ngenxa yokuba uyakwazi "bulala" iinxalenye enkulu.
• Fibrinoid - isifo apho umonakalo kwizicwili. Necrosis zengqondo okubangela izifo samathambo ezifana lupus okanye isifo samathambo. Esi sifo kakhulu kuchaphazela kwizihlunu agudileyo imithambo yegazi kunye imicu. necrosis Fibrinoid luphawulwa inguqu kwimeko eqhelekileyo collagen kunye ukuqokelelana izinto necrotic. iimviwo ngemikroskopu ancedisana ochaphazelekayo ziyafana fibrin. Kulo mzekelo, abafileyo abe umbala oqaqambileyo epinki. Imimandla abachatshazelwa necrosis fibrinoid, ibe isixa esikhulu immunoglobulin, kwakunye iimveliso kuwohloka fibrin kunye collagen.
• Amafutha - iziphumo sifo evela zokonzakala Ukopha ebuchotsheni, kwakunye njengokuphanga izicwili ndlala. Necrosis ichaphazela esisu namabele.
• Xuki - inokuba komile, igesi ofumileyo. Bedsores kwizigulane ezibhedini iyasebenza kolu hlobo necrosis. Amaninzi, imbonakalo sifo igalelo iintsholongwane abangena kwimimandla echaphazelekayo.

njengesilonda Dry njengendlela coagulation necrosis

njengesilonda Dry - isifo apho necrosis eluswini eyenzeke wadibana ne-bume lwangaphandle. Njengoko umthetho, kuphuhliso kwezifo kuzo naziphi na iintsholongwane akwenze. njengesilonda Dry ngokuqhelekileyo kuchaphazela imilenze. izixwexwe ezonakeleyo abe mnyama, umbala phantse omnyama, yaye aya esicaciswe ngokucacileyo. Olu tshintsho Umbala phantsi kwempembelelo emanzini. Oku kwenzeka ngenxa yokuba zombala haemoglobin eziguqulelwe kwi emanzini yentsimbi. njengesilonda Dry senzeka kule miqathango ilandelayo:

• Xa lwemithambo thrombosis kunye yamafutha yesiqephu.
• Xa baboniswa yomlenze amaqondo obushushu aphezulu okanye asezantsi (ngokuba ukutsha okanye frostbite).
• Ngophuhliso sifo Raynaud kaThixo.
• Phambi losulelo, ezifana yesifo.

Unyango wenziwa kuphela ukususwa zoqhaqho nyama.

nezilonda emanzi

njengesilonda emanzi - sisifo ukuvela yadibana igciwane kwi esikule yonakele. Esi sifo sichaphazela amalungu zizityebi ukufuma, kungenziwa kakhulu eluswini, kodwa sinabele nezibilini. njengesilonda emanzi kuchaphazela amathumbu (kunye nezithintelo kwemithambo) kunye emiphungeni (inyumoniya kwenzeka njengoko ngemiphumo).

Ngokufuthi, esi sifo kwenzeka abantwana kuba ngumsebenzi wabo xa uqhagamshela usulelo oluthambileyo ngakumbi ifomu ukubola. Hlula siyibhentsisile kwizihlunu ezithambileyo le nemihlathi kunye perineum. Isifo kuthiwa somhlaza amanzi. kwiindawo ezichaphazelekayo udumbile kakhulu yaye umbala emnyama. Akukho demarcates beesekethe ukuze isifo kunzima efanele unyango ngotyando, ngokuba kunzima ukumisela ukuba ngowuphi ekupheleni emzimbeni abachaphazelekayo. iindawo xuki abe livumba zingambi kakhulu, esi sifo idla ebulalayo.

Gas ekuboleni decubitus

Gas njengesilonda obubonakala ngendlela efana kakhulu ukuya lifumile kodwa yezizathu ezahlukeneyo. Olu hlobo njengesilonda olubakho xa kokuqala ochaphazelekayo ijwabu necrosis ukufumana iintlobo iintsholongwane perfringens zeClostridium, nabakuvuyelayo zixhaphakile. Iintsholongwane ubomi yakhe bahlukana igesi oluthile, nto leyo kubonakele zomzimba zizifo. Yokufa kwabantu esi sifo phezulu kakhulu.

Izilonda Pressure yenye yeendidi ekuboleni, apho inkqubo yokubulawa amalaphu. Izifo izigulane recumbent benegxaki, kwiindawo ezithile umzimba ukusuka immobilization elide phantsi koxinzelelo kwaye akazamkeli izinto ezifunekayo kunye negazi. Isiphumo ukufa kweeseli zolusu. Ekubulaleni ndawo ubuze beli sacrum, izithende, ithanga.

Uxilongo lwe coagulation necrosis

Moshilongo "necrosis coagulative", xa kukho umonakalo izinto zangaphandle, ugqirha yanele ukuba athathe igazi kwaye isampuli yokuvelisa amalungu ukwenzela uhlalutyo.

Ukuba kukho urhano of necrosis amalungu, uphando olwenziwa ebanzi kakhulu. Ukuze wenze oku:

• Ukuqhuba ray. Olu phando kubaluleke ngakumbi xa kukho urhano of njengesilonda gas.
• Ukuqhuba isifundo radioisotope. Sele uwunikiwe, xa-X ray abonisa akukho tshintsho (ngexesha lokuqala sifo). Umzimba lomntu lesitofu Radioactive. Ukuba kukho utshintsho emzimbeni necrotic lomzimba, oko izaku phawulwa kwindawo emnyama.
• Yokuziphatha CT. Kuliwa xa kukho urhano of izilonda ithambo.
• An MRI. Eyona ndlela isebenzayo yokuba uphando kwakunye nokuba utshintsho olungephi ezinxulumene nokuhamba kwegazi kakuhle.

ukungaphili necrosis

Necrosis i "ukufa" amalungu ezonakeleyo kunye namalaphu. Ngoko ke iintlobo zayo ezahlukeneyo, ezifana intliziyo, necrosis ingqondo, sezintso wesibindi, kungabangela ukufa ngamnye.

necrosis olubanzi kunokubangela iingxaki ezinkulu, ezifana bedsores ezininzi kuthinjwe izifo eziyingozi kunokwenzeka. nyama ayinabantu kwiimveliso yayo nokubola umzimba, ngaloo ndlela zikhokelela kubunzima ezinetyhefu. Nkqu iintlobo zamva zesi sifo kungakhokelela nesohlwayo, ezifana loloyiko engabalulekanga kwaye ukuyilwa cysts ebuchotsheni.

unyango necrosis

Unyango Necrosis luqala inkcazelo ngohlobo lwayo, babangela uvavanyo umonakalo kunye nokuchongwa kwezifo ezinxulumene.

Xa lokufunyaniswa "necrosis isikhumba" yabelwa unyango ngezihloko:

• Unyango kwiindawo ezichaphazelekayo Zelenko.
• Ukuhlanjululwa phezu ulusu usebenzisa ebulala.
• Bandaging nesisombululo "Chlorhexidine".

Izigulane ziye zabelwa unyango kunye ngotyando ukubuyisela kwegazi yesiqhelo, kubandakanywa nabo kwimimandla echaphazelekayo. utyando ne resection ye kwimimandla echaphazelekayo ngenjongo kaninzi lwenziwa ukususa iiseli abafileyo ulusu. umlenze yenzelwa ukukhusela iindawo onempilo ukunwenwa kwesi sifo.

necrosis olulophu amalungu zangaphakathi kunyangwa arhente anti-ukudumba, vasodilators, hondroprotektorov. Kwimeko unyango ngotyando nokungasebenzi konyango.
