Yog tias koj yog ib leej niam cev xeeb tub, lossis ib tus neeg uas yuav yug me nyuam sai sai no, ib qho ntawm thawj qhov kev kuaj mob uas koj tus kws kho mob yuav xaj yog kev kuaj ntshav. Qhov no yuav kuaj koj hom ntshav thiab lwm yam tseem ceeb heev. Ntawd yog koj tus Rh factor. Tej zaum koj yuav tau hnov lo lus no ua ntej. Tab sis ntau tus neeg tsis paub ntau txog nws txhais li cas. Rh factor yog dab tsi? Vim li cas nws thiaj tseem ceeb thaum cev xeeb tub? Tsis txhob txhawj, peb yuav tham txog nws yooj yim thiab meej.
Hauv lwm lo lus, Rh factor yog dab tsi?
Zoo, cia peb hais li no. Xav txog cov qe ntshav liab hauv koj lub cev ua cov pob me me, puag ncig. Ib txhia neeg muaj ib hom protein tshwj xeeb txuas rau ntawm qhov chaw, lossis sab nraud, ntawm cov qe ntshav liab no. Cov protein ntawd yog qhov peb hu ua Rh factor , lossis Rhesus factor, hauv kev kho mob.
Qhov no yog ib yam uas koj tau txais los ntawm koj niam thiab koj txiv.
- Rh-positive: Yog tias koj muaj cov protein nyob rau ntawm koj cov qe ntshav liab, koj yog Rh-positive. Hauv Sinhala, nws txhais tau tias Rh positive. Hauv Sri Lanka thiab lwm qhov ntawm lub ntiaj teb, feem ntau ntawm cov neeg, uas yog, kwv yees li 85 ntawm 100, yog Rh-positive.
- Rh-negative: Yog tias koj tsis muaj cov protein no nyob rau ntawm koj cov qe ntshav liab, koj yog Rh-negative. Qhov ntawd txhais tau tias koj yog Rh negative.
Koj cov ntshav hom A, B, AB, lossis O. Cov Rh factor no muaj feem cuam tshuam nrog cov ntshav hom ntawd. Piv txwv li, yog tias koj cov ntshav hom A thiab koj yog Rh-positive, koj cov ntshav hom tag nrho yog "A positive." Yog tias koj yog Rh-negative, nws yog "A negative."
Qhov tseem ceeb yog tias txawm koj yog Rh-positive lossis Rh-negative los tsis cuam tshuam rau koj txoj kev noj qab haus huv li cas los xij. Nws tsis yog ib yam kab mob. Nws yuav tsis ua rau koj raug mob li cas los xij. Qhov no tsuas yog qhov tseem ceeb rau cov xwm txheej tshwj xeeb xwb. Ntawd yog thaum cev xeeb tub.
Vim li cas Rh factor thiaj tseem ceeb thaum cev xeeb tub? (Rh Incompatibility)
Nov yog qhov tshwm sim. Peb hu qhov mob tshwj xeeb no ua Rh tsis sib xws , uas tsuas yog tshwm sim thaum leej niam yog Rh-negative thiab tus menyuam hauv plab yog Rh-positive .
Cia peb ua kom qhov no yooj yim dua. Xav txog koj lub cev ua lub tebchaws uas muaj tub rog tiv thaiv zoo. Vim tias koj yog Rh-negative, koj lub tebchaws (lub cev) tsis muaj cov protein Rh ntawd. Tam sim no, yog tias cov ntshav ntawm tus menyuam hauv koj lub tsev menyuam dhau los ua Rh-positive, qhov ntawd txhais tau tias tus menyuam muaj cov protein ntawd hauv nws cov qe ntshav liab.
Thaum cev xeeb tub, cov ntshav ntawm leej niam thiab tus menyuam feem ntau tsis sib xyaw ncaj qha. Tab sis qee zaum, tshwj xeeb tshaj yog thaum yug menyuam, me ntsis ntawm cov ntshav ntawm tus menyuam tuaj yeem nkag mus rau hauv cov ntshav ntawm leej niam.
Thaum qhov no tshwm sim, leej niam txoj kev tiv thaiv (lub cev tiv thaiv kab mob) pom cov protein Rh hauv cov ntshav ntawm tus menyuam ua tus yeeb ncuab sab nraud, tus neeg nkag tebchaws. Lawv xav tias, "Dab tsi yog yam tshiab no uas nkag mus rau hauv peb lub cev? Qhov no tsis yog peb lub cev," thiab lawv pib ua cov riam phom tshwj xeeb los tawm tsam nws. Peb hu cov riam phom no ua cov tshuaj tiv thaiv . Cov txheej txheem no hu ua Rh sensitization .
Cov xwm txheej uas cov ntshav ntawm tus menyuam sib xyaw nrog cov ntshav ntawm leej niam:
- Thaum lub sijhawm yug menyuam: Qhov no yog qhov xwm txheej uas feem ntau tshwm sim. Nws tuaj yeem tshwm sim thaum lub sijhawm yug menyuam los ntawm qhov chaw mos lossis thaum phais cesarean.
- Los ntshav ntawm qhov chaw mos thaum cev xeeb tub.
- Kev raug mob lossis kev sib tsoo rau lub plab.
- Cov teeb meem thaum cev xeeb tub thaum ntxov, xws li kev rho menyuam lossis cev xeeb tub ectopic.
- Thaum lub sijhawm kuaj tshwj xeeb xws li amniocentesis.
- Thaum tus me nyuam nyob rau hauv txoj hauj lwm breech, tus kws kho mob yuav sim tig tus me nyuam tes thaum lub sij hawm ua ECV.
Qhov kev pheej hmoo no puas cuam tshuam rau tus menyuam thawj zaug lossis tus menyuam thib ob?
Qhov no tseem ceeb heev. Feem ntau, tus menyuam Rh-positive thawj zaug ntawm leej niam Rh-negative tsis muaj teeb meem loj.
Qhov laj thawj yog, raws li peb tau tham ua ntej lawm, cov ntshav ntawm tus menyuam yuav nkag mus rau hauv niam lub cev thaum yug menyuam. Tom qab ntawd, thaum lub cev ntawm leej niam pib tsim cov tshuaj tiv thaiv kab mob, tus menyuam twb yug los lawm. Yog li tus menyuam thawj zaug yuav tsis raug mob.
Tiam sis, qhov teeb meem tiag tiag pib thaum cev xeeb tub tom ntej.
Tam sim no lub cev ntawm leej niam paub txog cov protein Rh thiab npaj los tsim cov tshuaj tiv thaiv kab mob los tawm tsam nws. Yog tias koj nqa tus menyuam Rh-positive hauv koj lub tsev menyuam rau zaum ob , cov tshuaj tiv thaiv kab mob uas koj tau ua ua ntej, xav tias, "Nov yog tus yeeb ncuab dua!", hla lub placenta thiab pib rhuav tshem tus menyuam cov qe ntshav liab. Nws zoo li kev ua tsov rog tau pib hauv tus menyuam.
Tus mob no hu ua tus kab mob Rh . Yog tias tsis kho, nws tuaj yeem ua rau muaj kev phom sij heev rau tus menyuam hauv plab.
| Niam tus Rh factor | Leej Txiv tus Rh factor | Tus menyuam Rh factor thiab kev pheej hmoo |
|---|---|---|
| Rh-negative (tsis zoo) | Rh-positive | Tus me nyuam yuav muaj Rh-positive. Muaj kev pheej hmoo ntawm Rh tsis sib haum. |
| Rh-negative (tsis zoo) | Rh-negative (tsis zoo) | Tus me nyuam yuav yog Rh-negative. Tsis muaj kev pheej hmoo. |
| Rh-positive | Rh-positive los yog Rh-negative | Tus me nyuam yuav muaj qhov kuaj pom tias muaj qhov zoo los yog qhov tsis zoo. Tab sis vim leej niam muaj qhov kuaj pom tias muaj qhov zoo, ces tsis muaj kev pheej hmoo. |
