Ischemia encane yamathumbu kanye ne-infarction

Ischemia yamathumbu kanye ne-infarction kwenzeka lapho kunokuncipha noma ukuvinjelwa komunye noma okungaphezulu kwemithambo ehambisa amathumbu amancane.

Kunezimbangela eziningi ezingaba khona ze-ischemia yamathumbu kanye ne-infarction.

• IHernia - Uma ithumbu lingena endaweni engafanele noma liminyene, linganqamula ukuhamba kwegazi.
• Ukunamathela - Ithumbu lingahle libhajwe ezicutshini ezibomvu (ukunamathela) kusuka ekuhlinzweni okwedlule. Lokhu kungaholela ekulahlekelweni kokugeleza kwegazi uma kushiywe kungalashwa.
• Embolus - Amahlule egazi angavimba omunye wemithambo ehambisa amathumbu. Abantu abaye bahlaselwa yisifo senhliziyo noma abane-arrhythmias, njenge-atrial fibrillation, basengozini yale nkinga.
• Ukuncipha kwemithambo - Imithambo ehambisa igazi emathunjini ingancipha noma ivinjwe ekwakheni i-cholesterol. Uma lokhu kwenzeka emithanjeni eya enhliziyweni, kubanga isifo senhliziyo. Uma kwenzeka emithanjeni eya emathunjini, kubangela i-ischemia yamathumbu.
• Ukuncipha kwemithambo - Imithambo ethwala igazi lisuse emathunjini ingahle ivinjwe amahlule egazi. Lokhu kuvimba ukugeleza kwegazi emathunjini. Lokhu kuvame kakhulu kubantu abanesifo sesibindi, umdlavuza, noma ukuphazamiseka kwegazi.
• Umfutho wegazi ophansi - Umfutho wegazi ophansi kakhulu kubantu asebevele bancipha imithambo yamathumbu emathunjini nawo angadala ukulahleka kwegazi eliya emathunjini. Lokhu kuvame ukwenzeka kubantu abanezinye izinkinga ezinkulu zezokwelapha.

Uphawu oluyinhloko lwe-ischemia yamathumbu ubuhlungu besisu. Ubuhlungu bukhulu, noma ngabe indawo ayithambile uma uthintwa. Ezinye izimpawu zifaka:

• Uhudo
• Imfiva
• Ukuhlanza
• Igazi esitokisini

Ukuhlolwa kwelabhorathri kungakhombisa ukubala okuphezulu kwamaseli amhlophe egazi (i-WBC) (umaka wokutheleleka). Kungahle kube nokopha kupheshana le-GI.

Ezinye izivivinyo ukuthola ubukhulu bomonakalo zifaka:

• Ukwanda kwe-asidi egazini (i-lactic acidosis)
• I-Angiogram
• I-CT scan yesisu
• I-Doppler ultrasound yesisu

Lezi zivivinyo azihlali ziyibona inkinga. Kwesinye isikhathi, ukuphela kwendlela yokuthola ischemia yamathumbu kunenqubo yokuhlinzwa.

Ezimweni eziningi, isimo sidinga ukwelashwa ngokuhlinzwa. Ingxenye yamathumbu efile iyasuswa. Iziphetho ezisele zamathumbu ziphinde zaxhunywa.

Kwezinye izimo, i-colostomy noma ileostomy iyadingeka. Ukuvinjelwa kwemithambo kuya emathunjini kuyalungiswa, uma kungenzeka.

Ukulimala noma ukufa kwezicubu zamathumbu yisimo esibi. Lokhu kungaholela ekufeni uma kungalashwa ngokushesha. Umbono uncike embangela. Ukwelashwa ngokushesha kungaholela emiphumeleni emihle.

Ukulimala noma ukufa kwezicubu zamathumbu kungadinga i-colostomy noma ileostomy. Lokhu kungaba okwesikhashana noma unomphela. I-Peritonitis ivamile kulezi zimo. Abantu abanesibalo esikhulu sokufa kwezicubu emathunjini bangaba nezinkinga ekumungeni izakhamzimba. Bangancika ekutholeni ukondleka ngemithambo yabo.

Abanye abantu bangagula kakhulu ngomkhuhlane kanye nokutheleleka kwegazi (sepsis).

Shayela umhlinzeki wakho wezokunakekelwa kwezempilo uma unezinhlungu ezinzima zesisu.

Izindlela zokuzivikela zifaka:

• Ukulawula izinto ezinobungozi, njengokushaya kwenhliziyo okungajwayelekile, umfutho wegazi ophakeme, ne-cholesterol ephezulu
• Ukungabhemi
• Ukudla ukudla okunomsoco
• Ukwelapha ngokushesha i-hernias

• Umthambo we-Mesenteric ischemia ne-infarction
• Uhlelo lokugaya ukudla
• Amathumbu amancane
