Abantwana badla ngokunikela ngegazi ukuze bahlalutye. Oku kubalulekile, ekubeni ukubunjwa kwamaseli egazini kunzima kwaye kukho utshintsho oluthile, ngexesha lesiphina isifo, sinokuxabisa okuxabisekileyo.
Yintoni i-hematocrit ebonisa?
Kuyaziwa ukuba igazi lomntu liqukethe izinto ezifanayo - i-erythrocytes, i-leukocytes kunye neeplatelet. Ngoko ke, kwiluhlu lovavanyo olufanayo lwegazi kukho isibonakaliso esibalulekileyo njenge-hematocrit. Ibonisa inqanaba le-erythrocytes egazini lomntwana, ngenxa yokuba zenza ubuninzi bezixhobo zamaselula. Ngokuqhelekileyo, inani le-hematocrit libonakaliswa njengepesenti yenani elipheleleyo legazi.
I-hematocrit ibalwa njani?
Kwiphubhu ekhethekileyo yeglasi kunye nexabiso lentluko, ebizwa ngokuba yi-hematocrit, uthele ixabiso elincinci legazi. Emva koko, kufakwa kwi centrifuge. Ngaphantsi kwesenzo sogonyamelo, i-erythrocytes ihlala ngokukhawuleza ibe phantsi, emva koko ilula ngokwaneleyo ukunquma ukuba yiyiphi inxalenye yegazi abayenzayo. Kufuneka kuqatshelwe ukuba abahlalutyi ngokuzenzekelayo baye basetyenziswa ngokubanzi kwii-laboratories zonyango zanamhlanje ukufumana inombolo ye-hematocrit.
I-Hematocrit yinto evamile kubantwana
Kubantwana, isiqhelo salo xabiso kuxhomekeke kwiminyaka yobudala:
- umntwana osanda kuzalwa - 44-62%;
- ukususela ekuzalweni ukuya kwiinyanga ezintathu-32-44%;
- ukususela kwiinyanga ezintathu ukuya ku-1 ngonyaka - 36-44%;
- ukususela kwiminyaka eli-1 ukuya kwi-10 iminyaka-37-44%.
I-Hematocrit isezantsi kumntwana-isizathu
Ngokusekelwe kwingcaciso, sinokucinga ukuba ixabiso le-hematocrit linciphisa ngokuncipha kwinani le-erythrocyte egazini lomntwana. I-hematocrit ithathwa njengancitshiswe kuma-20-25% kwaye oku kungakhokelela ngokufumaneka kweengxaki ezithile:
- ukwakha ukulibaziseka kwama-erythrocytes kumnyo wethambo;
- ukwanda kwinqanaba lokutshabalalisa i-erythrocytes egazini;
- kwandisa umthamo wegazi kumntwana;
- ukwanda kwindlela yokuxinwa kweeprotheni egazini (hyperproteinemia);
- igazi elincinci (ukungcolisa amanzi);
- ukuphuma kwegazi;
- i-anemia.
Kufuneka kuqatshelwe ukuba isalathisi esisodwa se-hematocrit ephantsi asikwazi ukuthetha ngokuchanekileyo malunga nokuba kukho nayiphi na ingxaki emzimbeni womntwana. Ukufumana umfanekiso ochanekileyo, esi sibonakaliso kwisivivinyo jikelele segazi sidibene nenqanaba le-hemoglobin. Kodwa nangona kunjalo, ukwenzela ukuba wenze i-diagnostic echanekileyo, nokuba kunjani na, kuyimfuneko ukuqhuba uviwo olugqithiseleyo kwaye unqume oko kwabangela ukuba kubekho ukulahla kwinani lamaseli egazi abomvu egazini.
