Nyob rau hauv ib lub cev noj qab haus huv uas tau ua tawm tsam ntawm cov kab mob pathogens, cov kev tiv thaiv kab mob muaj zog. Tab sis qee lub sij hawm muaj kev ua yuam kev, thiab microbes nkag rau hauv cov ntaub so ntswg ua rau kev puas tsuaj loj. Vim tias muaj tej yam tsis zoo ntawm sab nraud thiab sab hauv, necrosis (tuag ntawm cov nqaij) pib.
Cov ntaub ntawv thiab hom necrosis
Cov kws kho mob tshwj xeeb pom ob hom mob necrosis:
- Coagulation necrosis (qhuav) tshwm sim thaum nqaij tawv nqaij yog tais hauv qhov tsis muaj ntshav txaus thiab vim li ntawm kev sib sib zog nqus evaporation ntawm ya raws. Nyob rau hauv cov ntaub ntawv no, qhov cuam tshuam cov cheeb tsam tau ib tug daj-grey los yog hawj tsaus ntuj-xim av. Cov ntaub so ntswg ua tau qhuav thiab nkig, ua rau muaj mob hnyav, ua rau raug mob, thiab thaum nws qhib, ua fistula.
- Colliquated necrosis (ntub) yog ua los ntawm o thiab dilution ntawm cov ntaub so ntswg tuag. Vim li ntawm necroticisation, gray mash tsim nrog ib tus kab putrefactive qhia.
Muaj ntau hom necrosis:
- necrosis ntawm cov leeg nqaij (waxy los Zeckerov) yog txuam nrog qhov mob ntawm cov leeg nqaij skeletal;
- necrosis ntawm adipose cov ntaub so ntswg - tsis muaj kev vam meej nyob hauv cov nqaij rog;
- necrosis ntawm cov ntaub so ntswg;
- Caseous necrosis, tshwm sim hauv qhov tseeb tias cov cheeb tsam uas raug cuam tshuam pib crumble;
- gangrene - necrosis ntawm cov nqaij mos (qis thiab sab sab) thiab sab hauv nruab nrog cev;
- Qee luag - necrosis ntawm tawv (pob txha) nqaij;
- lub plawv nres uas tshwm sim los ntawm kev mob plawv hauv qee yam kabmob lossis cov nqaij.
Cov tsos mob ntawm cov nqaij mos necrosis
Ib qho ntawm thawj cov tsos mob ntawm cov necrosis yog qhov tsis hnov mob thiab hnov mob. Tib lub sijhawm, daim tawv nqaij nyob rau thaj tsam uas muaj cuam tshuam no zoo nkaus li ntau paler dua cov ntaub so ntswg uas nyob ib sab thiab tau txais ib yam dab tsi "khoom plig". Kho, pib nyob rau hauv thawj zaug ntawm tus kab mob, yuav pab kom tsis txhob muaj kev hloov ntawm pathological. Nyob rau theem no nws tseem ua tau kom rov qab tau ntshav. Yog tias qhov ntsuas tsis raug, qhov tawv nqaij yuav yog xim cyanotic, ces maj mam tig dub. Lwm cov cim qhia ntawm necrosis ntawm cov nqaij mos ntawm cov ceg tawv:
- kev sib ceg;
- sib quas ntus ;
- trophic ulcers.
Tsis hais txog qhov chaw uas cuam tshuam los ntawm necrosis, kev ua txhaum tshwm sim nyob rau hauv cov kev ua:
- lub paj hlwb;
- raum;
- nplooj siab;
- kab mob ntsws.
Qhov no yog nrog los ntawm:
- txo kev tiv thaiv;
- Kev puas tsuaj ntawm kev ua metabolic, ua rau hypovitaminosis thiab kev qaug zog;
- phem lub xeev ntawm kev noj qab haus huv, tas li overwork.
Kho cov ntaub so ntswg necrosis
Txoj kev kho ntawm qhuav thiab ntub dej necrosis muaj ntau qhov sib txawv.
Kev kho mob hauv zos nrog coagulation necrosis yog ua:
1. Cov kev ua ub no tiv thaiv kev sib kis ntawm pathology, nrog rau:
- kev kho mob ntawm daim tawv nqaij nrog antiseptics nyob ze cheeb tsam.
- daim ntawv thov hnav khaub ncaws nrog cov tshuaj tua kab mob;
- ziab ntawm daim tawv nqaij ntawm lub tsev kawm ntawv ntawm cov kab mob nrog cawv pob zeb diamond zaub los yog 5% daws ntawm poov tshuaj permanganate.
2. Necrectomy (excision ntawm cov ntaub so ntswg uas tsis muaj qhov tseeb).
3. Kev kho mob ntawm tus kab mob lwm yam uas ua rau mob necrosis, xws li:
- restoration ntawm kev hloov ntshav ;
- txhim kho cov ntshav;
- kev tiv thaiv ntawm kev kis mob los ntawm kev siv cov tshuaj tua kab mob.
Cov kev kho mob ntawm colliquated necrosis nyob rau hauv cov theem thaum ntxov muaj kev sim hloov nws mus rau ib qho kev nyab xeeb, qhuav daim ntawv.
Cov kev kho mob hauv zos muaj nyob hauv cov txheej txheem hauv qab no:
- ntxuav nrog 3% kev tov tshuaj hydrogen peroxide;
- qhib cov swells, kua faj;
- daim ntawv thov antiseptic dressings;
- lub imposition ntawm gypsum langettes.
Ntxiv mus, cov hauv qab no:
- cov tshuaj tua kab mob hauv intravenous thiab intra-arterial ntawm cov tshuaj tua kab mob;
- detoxification;
- kev kho plawv.
Nrog rau kev mob ntawm kev mob thiab qhov tsis tuaj ntawm kev kho tus txheej txheem ntawm kev kho kom zoo, kev ua haujlwm rau kev tshem tawm cov ntaub so ntswg uas tsis raug siv yog pom zoo.
