Hemoglobin kubantwana

Uvavanyo oluqhelekileyo lwegazi luhlolisiso olwenziwa rhoqo ngabantwana nangabantu abadala. Olu vavanyo olulula lunikeza ulwazi olunolwazi olubalulekileyo malunga nesimo sengqondo somguli. Zonke izikhombisi ezichazwe lulolu hlalutyo zibaluleke kakhulu ukuxilongwa. Enye yeeparitha apho ugqirha ugxininisa xa ukuvavanya iziphumo yi-hemoglobin. Iprotheni eyinkimbinkimbi ethatha inxaxheba ngokuthe ngqo ekutshintsheni i-oksijini kwiimfucu, kunye ne-carbon dioxide kwimipopu. Inomsebenzi onoxanduva ochaphazela impilo yempilo.

Inqanaba likaHemoglobin kubantwana

Ixabiso eliqhelekileyo le parameter lihlukile kubantwana beeminyaka ezahlukeneyo. Uxinzelelo oluphezulu lwalo protein lufumaneka kwigazi leintsana. Ukunciphisa umzimba kunokuqatshelwa kwiinyanga ezili-12 zokuqala emva kokuzalwa kweemvumba. Imigangatho yexabiso le-hemoglobin kubantwana ngeminyaka liyakubonwa kwiitheyibhile ezikhethekileyo.

Ukuba isifundo sibonisa ukuphambuka kweerameters ukusuka kwixabiso elithethiweyo, oko kungabonisa ukuphulwa kwimpilo. Ugqirha kufuneka amisele isigqibo sawo kwaye amisele unyango olufanelekileyo.

Iimbangela ze-hemoglobin ephantsi kubantwana

Ukuba umntwana wayelele ngexesha lokusasazwa kwegazi, ixabiso lingahamba ngaphaya komda osezantsi wesiqhelo. Kwakhona kunokwenzeka emva kokutya kunye nexesha elide ukusuka ku-17.00 ukuya ku-7.00. Ngoko ke, ukufumana iziphumo eziphambili, kufuneka uqikelele ngokucacileyo imigaqo yokunikela ngegazi.

I-hemoglobin eyancitshiswayo kwimpawu zomntwana ekuphuhliseni i- anemia. Le meko ingabangela ukubuyela emva kokukhula kwengqondo nangokwenyama. Abantwana abane-anemia bakhawuleze bathathele, bajongwa ngokubethelwa rhoqo kunye nokucasula. Abantwana abanjalo bahlala begula, banamathele ekuphuhlisweni kweengxaki, banokutheleleka kwizifo. Yingakho i-hemoglobin ephantsi kumntwana inobungozi. Ezi zinto zilandelayo zingakhokelela kwimeko efanayo:

• ukutya okunonophelo komama onesihlengikazi okanye ukulingana okungafaniyo kwemvumba;
• izifo zengqondo;
• ukuphuma kwamanzi ahlukeneyo, kubandakanywa ukuphuma kwegazi, umzekelo, ngezifo ezithile zesisu;
• umsebenzi owenziwe ngokomzimba womntwana okanye, ngokuchaseneyo, umthwalo wokusebenza ogqithiseleyo;
• amanye amayeza.

Iimbangela ze-hemoglobin ephezulu kumntwana

Ukuba isifundo sibonisa ukuphambuka kwesiqhamo kwisikhokelo esiphezulu, ke oku kunako ukuphawula ugqirha. Ezi zinto zilandelayo zingakhokelela kulo rhulumente:

• ukwanda kwinqanaba le-erythrocytes;
• ukupheliswa kwamanzi;
• ukungapheli kwentliziyo.

Ukwenyuka kwamanga kwizinga le-hemoglobin kubantwana kuholele kumxholo ophezulu we-leukocyte egazini. Kwakhona kunokwenzeka ukuba izinto eziphathekayo zithathwe kwi-vein kwaye i-tourniquet isetyenziswe ngaphezu kwe-1 ngomzuzu.
