Unegazi elingakanani emzimbeni wakho? Masifunde ngoVavanyo lweMithamo yeGazi ngokulula (uVavanyo lweMithamo yeGazi)

Sonke sithetha ngoxinzelelo lwethu lwegazi kunye namanqanaba eswekile egazini kwaye siwajonga rhoqo. Kodwa ngaba wakha wazibuza ukuba lingakanani igazi onalo emzimbeni wakho? Oko kukuthi, ingaba elo nani legazi lilungele umzimba wakho? Okanye lininzi kakhulu? Okanye lincinci kakhulu? Namhlanje siza kuthetha ngovavanyo olukhethekileyo olufuna ukuphendula loo mbuzo.

Yintoni le Blood Volume Test?

Ngamafutshane, uvavanyo lweBlood Volume luvavanyo olulinganisa inani elipheleleyo legazi emzimbeni wakho. Oku akufani novavanyo lwegazi oluqhelekileyo. Olu lukwicandelo elibizwa ngokuba yiNuclear Medicine. Musa ukoyika igama elithi "nuclear." Oku kuquka ukusebenzisa into encinci kakhulu, engenabungozi ene-radioactive ukufunda indlela iinkqubo ezithile ezenzeka ngayo emzimbeni. Kufana nokukhanyisa itotshi encinci ngaphakathi emzimbeni.

Masiqale sijonge ukuba igazi lethu lenziwe ngantoni.

Ngaphambi kokuba siqonde olu vavanyo, masizikhumbuze ngokufutshane ukuba yintoni esegazini lethu. Igazi lethu aliyonto inye. Liqoqo lezinto ezininzi.

Kwezi zinto, iiseli ezimhlophe zegazi kunye neeplatelets zenza ngaphantsi kwe-1% yomthamo wegazi. Ke ngoko, uVavanyo lweMithamo yeGazi lulinganisa ikakhulu ubungakanani beplasma kunye neeseli ezibomvu zegazi . Ke ngoko, olu vavanyo ngamanye amaxesha lubizwa ngokuba yi-"Plasma Volume Test".

Umzimba wethu ulawula njani eli nani legazi?

Umzimba wethu ngumatshini omangalisayo. Ngaphakathi kuwo, kukho inkqubo entsonkothileyo esebenza ukugcina umthamo wegazi ukwinqanaba elifanelekileyo.

• Iiseli ezibomvu zegazi: Iiseli ezibomvu zegazi ezintsha zenziwa kumongo wethambo ngaphakathi emathanjeni ethu. Iiseli ezindala ziyatshatyalaliswa zize zisuswe sisibindi sethu. Le nkqubo ithatha ixesha. Ukuba kulahleke igazi elininzi ngenxa yengozi, kungathatha iintsuku, okanye iinyanga, ukuba kwenziwe iiseli ezibomvu zegazi ezintsha.
• Iplasma: Iplasma ikakhulu ngamanzi. Ngoko ke kukhawuleza kakhulu ukuyilawula kunokwenza iiseli ezibomvu zegazi. Umzimba ufumana ulwelo emanzini esiwaselayo nasekutyeni esikutyayo. Ulwelo lulahleka emzimbeni ngokubila, umchamo, nokuphefumla. Izintso zethu zezona ziphambili ezigcina olu lwelo lulungelelene.

Umntu omdala oqhelekileyo une-5 litres yegazi emzimbeni wakhe. Nangona kunjalo, eli nani linokwahluka ngenxa yezifo ezahlukeneyo okanye ezinye izizathu.

Ukwanda komthamo wegazi (i-Hypervolemia) kunye nokwehla komthamo wegazi (i-Hypovolemia)

Kukho iimeko ezimbini eziphambili ezenzekayo xa umthamo wegazi udlula amanqanaba aqhelekileyo. Makhe sijonge ezi zimbini ngokwahlukeneyo.

Luthini ulwalamano phakathi komthamo wegazi kunye noxinzelelo lwegazi?

Kulula kakhulu ukuyiqonda le nto. Cinga ngombhobho ompontshwa ngamanzi yinjini yamanzi.

• Xa umthamo wegazi unyuka (iHypervolemia): Kufana nokufaka uxinzelelo lwamanzi olungaphezulu kumbhobho. Uxinzelelo olungaphakathi kwimithambo yegazi luyanda. Oko kuthetha ukuba uxinzelelo lwegazi luyanda.
• Xa umthamo wegazi wehla (iHypovolemia): Kanye njengokuba umlinganiselo wamanzi kwityhubhu uncipha, uxinzelelo olungaphakathi kwimithambo yegazi luyancipha. Oko kuthetha ukuba uxinzelelo lwegazi luyehla. Umzimba uzama ukugcina uxinzelelo ngokubangela ukuba imithambo yegazi inciphe. Kodwa ukuba ukulahleka kwegazi kukhulu, umzimba awukwazi ukululawula.

Ngoko ke olu vavanyo lufanele lwenziwe nini?

Olu ayilovavanyo oluqhelekileyo olufanele wonke umntu. Oogqirha bacebisa olu vavanyo ngakumbi kwizigulane ezikwiYunithi yoNyango oluNgxamisekileyo (ETU) okanye kwiYunithi yoKhathalelo oluNgxamisekileyo. Lungafuneka nakwiimeko ezilandelayo:

• Kwimeko yokopha kakhulu
• Kwimeko yokuphelelwa ngamanzi emzimbeni kakhulu
• Kwiimeko zentliziyo
• Kwimeko yezifo zezintso okanye zesibindi
• Kwiingozi zokutsha kakhulu
• Kwizigulane ezikwimeko yokwethuka
• Ukufumana unobangela we-anemia
• Ukufumana unobangela we-syncope rhoqo
• Ukuba unegazi eliphezulu okanye eliphantsi elingalawulekiyo
• Ukujonga imeko yesigulana ngaphambi kotyando olukhulu

Masifunde inyathelo ngenyathelo indlela yokwenza uvavanyo.

Olu vavanyo ludla ngokwenziwa esibhedlele. Lungenziwa kanye ecaleni kwebhedi yakho, okanye kusenokufuneka uye kwicandelo lezonyango lwenyukliya.

Ulungiselela njani ngaphambi kovavanyo?

Ugqirha wakho uza kukucebisa ngale nto. Ngokwesiqhelo,

• Uza kucelwa ukuba ungatyi okanye ungaseli kangangeeyure ezimbalwa ngaphambi kovavanyo.
• Musa ukusela iziselo ezine-caffeine, njengekofu okanye iti, ngomhla wovavanyo. I-caffeine iyi-diuretic.
• Ukuba usela amayeza, qiniseka ukuba ubuza ugqirha wakho ukuba ufuna ukuwayeka ngaphambi kovavanyo.

Kwenzeka ntoni ngexesha lovavanyo?

Le nkqubo ilula kakhulu. Akukho nto inokubangela uxhalabe ngayo.

1. Okokuqala, ingcali iza kulinganisa ubude nobunzima bakho.

2. Emva koko i-cannula (umgca we-IV) iya kufakwa kumthambo osengalweni yakho.

3. Ufanele ulale kamnandi ebhedini.

4. Okulandelayo, isixa esincinci kakhulu se-radioactive substance endikhankanyileyo ngaphambili (`Iodine-131 human serum albumin (HSA)`) sifakwa emzimbeni nge-cannula.

5. Linda malunga nemizuzu eli-12 ukuze le nto ixubane kakuhle negazi lakho.

6. Emva koko, kuthathwa iisampuli zegazi ezininzi malunga nemizuzu emi-6 zize zithunyelwe kwilabhoratri.

7. Yonke le nkqubo ayithathi ngaphezulu kwemizuzu engama-90.

Wenza ntoni emva kovavanyo?

Xa uvavanyo lugqityiwe, i-cannula iya kususwa. Ungaya ekhaya. Ezinye zezinto ezine-radioactive ezafakwa emzimbeni wakho ziya kukhutshwa kumchamo wakho, ngelixa ezinye ziza konakala ngokwemvelo zize zinyamalale emzimbeni wakho. Kubaluleke kakhulu ukusela amanzi amaninzi ukuze kukhawuleziswe le nkqubo.

Ngaba kukho naziphi na iingozi ngolu vavanyo?

Njengakuyo nayiphi na imviwo yezonyango, kukho izinto ezimbalwa ekufuneka uzikhumbule.

• Ukuba ukhulelwe okanye uncancisa: Olu vavanyo alukhuthazwa ukuba ukhulelwe okanye uncancisa. Ngoko ke, ungenza uvavanyo lokukhulelwa ngaphambi kovavanyo ukuqinisekisa ukuba ukhulelwe na.
• Ii-Allergies: Ukuba une -allergies kwi-iodine, ukutya kwaselwandle okufana ne-shellfish, okanye amaqanda , ngokuqinisekileyo kufuneka uxelele ugqirha wakho.Ukuba kunjalo, ugqirha angalutshintsha uvavanyo ukuze angabi nokubangela ukuba umntu angabi namdla.
• Iziphumo kwi-thyroid gland: I-radioactive iodine esetyenziswe kuvavanyo ingonakalisa i-thyroid gland yakho. Ukuthintela oku, uya kunikwa ipilisi ye-iodine ukuba uyisele ngaphambi kovavanyo. Emva koko, i-thyroid gland yakho iyayifunxa i-iodine, ithintele ukufunxwa kwe-radioactive iodine.

Zithini iziphumo?

Ingxelo yovavanyo ibonisa ngokucacileyo ukuba umthamo wegazi lakho uqhelekile, uphantsi, okanye uphezulu.

Olu lwazi lubaluleke kakhulu kugqirha wakho. Lunokuba luphawu olukhulu lokukunceda ufumane unobangela wesifo sakho. Umzekelo:

• Ukuba igazi lakho liphantsi (i-hypovolemia) , unganikwa ulwelo olufana ne-saline okanye, ukuba kuyimfuneko, utofelo-gazi.
• Ukuba unegazi elingaphezulu (hypervolemia) , unganikwa amayeza okukunceda ukhuphe ulwelo olugqithisileyo emzimbeni wakho ngomchamo.

Ngale ndlela, iziphumo zolu vavanyo ziluncedo kakhulu koogqirha ekumiseleni ngokuchanekileyo ukuba loluphi unyango abafanele balunike isigulane kunye nomlinganiselo walo.
