Ngesikhathi sokubeletha, ingane enesibelethweni sikamama izwa isidingo esinzima futhi esivamile sokunikezwa umoya okwanele kanye nezinto ezidingekayo ekuthuthukiseni. Ukumnika konke okudingekayo futhi ngokugcwele, imvelo idale izitho ezinjalo eziyingqayizivele njenge-chorion kanye ne- placenta yokukhulelwa .
I-chorion yi-membrane yangaphandle yama-embryonic ejikelezayo umbungu futhi yenziwa ngesikhathi sokutholwa kokuqala. Inombono omkhulu wemikhumbi ehlangene engena ezindongeni zesisu.
Njengoba isikhathi sokubeletha sanda, ubukhulu bezinhlobo ezinjalo bukhula njalo, bambaza futhi babuye baba yi-villi eyinqaba ye-chorion. Lezi zinsuku zihlinzekela ngokugcwele umzimba phakathi komama nomntwana. Ubuningi be-chorion emavikini angu-13 bukhulu kangangokuthi kancane kancane luguqulwa libe yi-placenta. Ngumzimba wesikhashana oyoba necala lokusebenza kwengane ngesikhathi sokubeletha.
Ngesikhathi sokukhulelwa, okunamathiselwe okulungile kwe-chorion enesibindi kudlala indima ebaluleke kakhulu, enqunywe kwiseshini yokuqala ye-ultrasound. Njengomthetho, kunezinhlobo ezintathu zezakhi zendawo, okungukuthi:
- emdongeni wangemva kwesibeletho;
- phambili;
- okunamathiselwe okuphansi.
Konke akubhekwa njenge-pathologies futhi akumele kubangele ukwesaba kumama ozayo.
Ukwakhiwa kwe-chorion, ebonakalayo kwi-monitor ye-device ye-ultrasound, iboniswa ngendandatho emhlophe, enezincazelo ze-wavy futhi itholakala engxenyeni yangaphandle yeqanda le-fetal. Ukutadisha okunembile kunika ithuba lokucabangela ngisho ne-villi encane kakhulu. Ubuningi be-chorion ekuqaleni kwezinyathelo zokukhulelwa kulinganiswa ngamamitha futhi, njengoba umthetho, cishe ulingana nesikhathi sokugqoka emasontweni.
Iyini imisebenzi ye-chorion ngesikhathi sokukhulelwa?
Lo mzimba uqala umsebenzi wawo ezinyathelweni zakuqala zokuthuthukiswa kombungu futhi uqukethe okulandelayo:
- ukuhlinzeka nge-gas exchange phakathi komama nomntwana;
- ukuvikelwa kwe-fetus kusuka kwizifo kanye namagciwane;
- umsebenzi we-trophic ne-excretory.
Ngokuvamile, omama abasebasha, sebewutholile imiphumela yocwaningo ngedivaysi ye-ultrasound, babhekana nenani elikhulu lemibono engaqondakaliyo neyesabisayo ehambisana nalesi sitho sesikhashana. Cabanga ngokujwayelekile kubo:
- I-chorion yonyaka - lena ifomu evamile, eligcina kuze kube amasonto angu-8 noma angu-9 wokubeletha. Ngemuva kwalesi sikhathi, i-chorion iguqulwa ibe yincane futhi igxile, okudingekayo ekuguquleni kwayo ibe yi-placenta nokuhlinzekwa okuphelele kwengane nazo zonke izinto ezidingekayo.
- I-cyst chorionic ngokuvamile iwumphumela wokuvuvukala okhulelwe ngesikhathi sokukhulelwa noma nje ngaphambi kokukhulelwa. Isayithi lapho i-cyst etholakala khona ayinikezwa ngegazi futhi ihlukaniswe ne-placenta. Ngokuvamile ama-formations anjalo ayamancane futhi angashadile, futhi awaphazamisi inkambo yokukhulelwa.
- I-Hyperplasia ye-chorion yinkqubo yokwandisa inani lama-capillari ayo kanye nokwandiswa kwayo. Lokhu kuzonikeza ithuba lokulondoloza impilo yengane,
uma ukulethwa kungenzeki ngesikhathi. - Isakhiwo esiyingqayizivele se-chorion noma ukuthuthukiswa kwayo okungaphelele kungaholela ekuphumuleni komzimba okuzenzakalelayo. Le nqubo isabizwa ngokuthi i-hypoplasia. I-Vorsinki chorion ngokweqile iphuka kude nodonga lwesibeletho kanye ne-egg fetal exfoliates.
- Ngokuvamile kunenkinga ngokuchaza ukuthi yikuphi: "i- vascular chorionic villus ". Esigabeni sokubunjwa kwalesi sitho, ukungasebenzi kungahle kwenzeke, futhi imithwalo yegazi ayikwazi ukubekwa.
Isiphetho esihle kakhulu se-ultrasound kumama wesikhathi esizayo "isakhiwo esingaguquki se-chorion", uma sikhishwa ngaphambi kwamasonto angu-10-11. Uma kungenjalo, lokhu kungase kusho ukuthi ukukhulelwa akuhambanga ngendlela edingekayo.
