Blood amahlwili, nanjengokwesimo kwaye ukutenxa kulo

Coagulation okanye hemostasiogram - uvavanyo egqiba ekunqandeni igazi. ixesha kwiSithethe ezophayo xa yonakele isikhumba - imizuzu 2-3 emva igazi laba isitya yegazi. Ukuba inkomba baphambuke kwicala elinye okanye omnye, ugqirha imisela iimpawu zohlalutyo kwephulwa elabangela nokungavisisani, kwaye atyumbe unyango kuyimfuneko.

Coagulation elawulwa ngethuba loviwo ngethuba lokukhulelwa, kwiimeko izifo zesibindi kurhanelwa kwixesha ipreoperative okanye postoperative. Kwakhona yezifo samathambo yaye igazi ekunqandeni lwezidumbu, imithambo varicose kunye nesifo semithambo ibonisa nohlahlelo coagulation kwegazi. UNorma ekunqandeni kuxhomekeke kubungakanani prothrombin egazini.

Wabiza prothrombin protein onoxanduva ekunqandeni igazi. Yena njengesakhi esibalulekileyo kwenye protini igazi - thrombin. Ngoko ke, okwenza umncedisi beyaleza kuphela ixesha ibalwe ngqo, kodwa ke umchiza ukwakhiwa penti, ipesenti iiprothini ezibonakalisa ekunqandeni igazi. Ummiselo kwi amanqanaba egazini prothrombin - 78-142%.

Blood, ibekwe imithambo yegazi, ngokutsho viscosity yayo fluidity kufana amanzi. Le imeko engundoqo apho egazini uyakwazi ukwenza umsebenzi wayo ophambili - ukuhamba ngapha neempahla, ukunika onke amalungu oksijini, iiprotheni, iivithamini kunye nezinye izinto eziyimfuneko. Kodwa ngexesha umonakalo udonga isitya kunye kokuphela yakhe ebhedini yakhe, yaye xa engena thromboplastin inyama iquka inkqubo ebonelela ekunqandeni igazi. UNorma ixesha thrombin, oko kukuthi, ixesha iclotting - 11-17,8 s (kwimizuzu).

Ukuba izinga ekunqandeni igazi isigulane bazitshitshisela lithomalele yayo, kukho umngcipheko ukopha ophezulu ngexesha utyando okanye umonakalo ngengozi, kwakunye ngexesha lokubeleka kunye sexesheni. Amaxesha amaninzi lo ngezifo kwenzeka abanesifo seswekile sinwenwa okanye unyango ixesha elide kunye anticoagulants ngqo.

Ngabantu, amatyala yesifo azalwa ekuthiwa kubazali bakhe, nto leyo njengelifa. Abasetyhini andimvumeli ukusuka sifo, kodwa abathwali kubazali bakhe sofuzo.

Ukuze ukubuyisela ekunqandeni kubaguli migangatho ukumisela fibrinolysis inhibitors, coagulants amanyathelo ngqo ethatyathwe kwigazi, vitamin K okanye iziyobisi "Vikasol", protamine sulfate, okanye wenze isigulane nge plasma yegazi. Zonke ezi iziyobisi neenkqubo isantya iinkqubo ezisebenzisa sokuchitha egazi igazi ayeke ukopha.

Ke ukuba, phezu koko, isigulana sele kunciphise ixesha ekunqandeni? UNorma amahlwili, njengokuba sele kukhankanyiwe, imizuzu 2-3, kwaye isigulane liqengqiwe, ngoko nangoko? Ngoko ke omkhulu! ukopha kancinci kulo mzekelo, yintoni ingxaki?

Kubonakala, nje into ezi ezinxaxhileyo zezona yingozi. Lenyuka ekunqandeni asongele nomonde stroke, thrombophlebitis, varicose, hemorrhoids kunye nezinye.

Kutheni kukho i anomaly onjalo? Izizathu ekunqandeni yegazi eyonyukileyo lukhulu. Umzekelo, ukulahlekelwa lomzimba ulwelo lurhudo lweenkcukacha okanye ugabhe okanye ityhefu okanye izifo ezosulelayo emathunjini; kwi wenyuse umchamo, nto leyo uphawu zizifo sezintso, isifo seswekile okanye isifo seswekile insipidus; xa uthatha amayeza athile; eshe olubanzi kwaye linetyhefu nokudumba nezengekho miphungeni.

Kwakhona uphawu ukwanda amahlwili kunokwenzeka ngenxa fermentopathia naso okanye lufundiwe, izifo olwaye lwamfimfitha, isifo sesibindi, umonakalo endothelial, izifo semithambo, stasis (deceleration sindululo okanye akukho ukupheliswa) kwi emithanjeni, kaninzi ngenxa ischemia, yemo lwemithambo okanye izilonda ezinetyhefu igunya. Ngexesha ekhulelwe okanye ngexesha ulwamkelo ezinye iindlela zokuthintela nayo kufumana okwandileyo coagulation igazi syndrome.

Le syndrome - kwinqanaba lokuqala DIC. Unyango amayeza intsomi, isifo phantse Awekho. Ngokufuthi, izigulane emiselweyo unyango entsonkothileyo nomonde, ekufuneka zilandelwe ngokuthe ngqo.
