Ua ntej koj tham txog Rh-qhov teeb meem thaum cev xeeb tub, koj yuav tsum to taub qhov Rhes zoo li cas, thiab nyob rau cov xwm txheej qhov kev sib tawm tsam no. Li ntawd, Rh Factor yog ib qho ntawm cov ntshav pawg antigens, uas muaj nyob rau ntawm cov ntshav liab liab (cov ntshav liab). Feem ntau cov neeg muaj cov tshuaj antigens (los yog cov proteins) tam sim no, tab sis qee zaus lawv tsis yog.
Yog tias ib tus neeg muaj Rhesus zoo nyob rau ntawm cov ntshav liab, ces lawv hais tias nws yog Rh-positive, yog tias tsis muaj, Rhesus-tsis zoo. Thiab tom qab ntawd koj tsis tuaj yeem hais tias rhesus zoo dua. Lawv tsuas yog txawv - qhov ntawd yog txhua yam.
Ib qho tseem ceeb hauv Rhawv yog thaum cev xeeb tub. Yog hais tias yav tom ntej niam yog Rh-negative, thiab leej txiv ntawm tus menyuam yog Rh-positive, nws muaj feem yuav tsim kev nyuaj siab ntawm tus niam thiab tus me nyuam. Qhov ntawd yog, yog tias tus menyuam yuav muaj Rh tus pojniam txawv tus pojniam, qhov no yuav ua tau rau tus niam thiab tus xeeb ceem.
Qhov rhais ntawm Niam thiab Me Nyuam Muaj Feem Xyuam hauv 75% ntawm tus neeg mob, yog tias tus me nyuam leej niam leej txiv muaj ntau yam Rh factors. Qhov tseeb, qhov no tsis yog kev zam txim rau tsis kam tsim ib tse neeg, vim hais tias thaum lub sijhawm cev xeeb tub thawj zaug tsis sib haum xeeb, thiab nrog kev tswj cov teeb meem ntawm cev xeeb tub nrog nws tuaj yeem zam dhau thaum cev xeeb tub.
Thaum muaj teeb meem rhesus?
Yog tias koj cev xeeb tub rau thawj zaug, ces qhov kev pheej hmoo uas yuav muaj tus kabmob Rh-me me yog tsawg, vim tias tsis muaj cov tshuaj tiv thaiv rau Rh-negative lub cev hauv leej niam lub cev. Thaum cev xeeb tub thiab thawj lub rooj sibtham ntawm ob lub rhesus, tsis muaj ntau hom tshuaj tiv thaiv. Tab sis yog hais tias muaj ntau ntawm erythrocytes ntawm lub fetus tau txais mus rau hauv cov ntshav ntawm leej niam, tom qab ntawd ces hauv lub cev nws muaj txaus "nco lub hlwb" los tsim cov tshuaj tiv thaiv tawm tsam Rhesus hauv kev xeeb tub tom ntej.
Qhov teeb meem ntawm qhov teeb meem no yog nyob ntawm seb qhov ua ntej yuav xeeb menyuam thawj zaug. Yog li, yog tias:
- muaj ib tug nchuav menyuam - tshuaj tua kab mob hauv cov ntshav yog ua rau 3-4% ntawm tus neeg mob;
- kev rho menyuam tawm ntawm kev kho mob - qhov kev pheej hmoo ntawm kev sib haum xeeb yog nce mus rau 5-6%;
- ectopic cev xeeb tub tshwm sim - hauv 1% ntawm tus neeg mob;
- Lub cev xeeb tub tau yug hauv ib txwm yug - qhov kev pheej hmoo yog 10-15%.
Tsis tas li ntawd, qhov kev pheej hmoo ntawm kev mob nyhav tsub ntxiv tom qab lub hnub nyoog caesarean thiab cov plhaus nkawg plhu. Tiam sis, txawm li cas los xij, txhua tus niam uas muaj teeb meem ntawm Rhesus-Kev sib haum xeeb xav tau kev tiv thaiv ntawm qhov kev phom sij xws li tus kab mob hauv tus cwj pwm ntawm lub fetus .
Rhesus tsis sib haum xeeb thiab nws lub txim
Yog hais tias leej niam muaj Rh-antibodies, thiab tus me nyuam tus Rh-zoo, ces cov tshuaj tiv thaiv tus me nyuam ua ib yam dab tsi txawv teb chaws thiab tawm tsam nws cov erythrocytes. Nyob rau hauv nws cov ntshav hauv teb, ntau bilirubin yog ua, uas dyes daim tawv nqaij daj. Qhov phem tshaj plaws hauv qhov no yog tias bilirubin ua rau tus menyuam lub hlwb puas.
Tsis tas li ntawd, vim cov ntshav liab ntawm lub fetus raug puas los ntawm cov tshuaj tiv thaiv ntawm leej niam, nws lub siab thiab tus khaus khaus ceev cov qoob loo ntawm cov ntshav liab tshiab, thaum lawv tus kheej nce qhov loj. Tiam sis lawv tsis tuaj yeem tiv nrog lub plab hlaub ntshav liab, thiab muaj lub zog hnoos qog ntawm lub fetus, vim cov qe ntshav liab tsis xa cov pa oxygen rau ntawm qhov ntau ntau.
Qhov txiaj ntsim loj tshaj plaws ntawm Rhesus-tsis sib haum xeeb yog theem kawg - kev loj hlob ntawm hydrocephalus, uas tuaj yeem ua rau nws txoj kev tuag hauv lub cev .
Yog tias koj muaj cov tshuaj tua kab mob hauv koj cov ntshav thiab lawv lub titer nthuav, koj xav tau kev kho nyob rau hauv pawg ntseeg tshwj xeeb perinatal, qhov chaw koj thiab tus me nyuam yuav tau txais kev saib xyuas txhua lub sijhawm. Yog tias koj tswj "tuav" qhov uas cev xeeb tub rau 38 lub lim piam, koj yuav muaj kev txiav txim siab caesarean. Yog tias tsis yog, tus me nyuam yuav raug muab ntshav pub rau hauv lub tsev me nyuam, uas yog, los ntawm phab ntsa hauv plab ntawm leej niam mus rau txoj hlab ntaws thiab 20-50 ml ntawm erythrocyte mass yuav raug muab tso rau hauv nws.
