Kwiiveki ezili-12 zokukhulelwa, i- trimester yokuqala yokukhulelwa iya kufikelela ekupheleni. Unokuphefumula ukukhulula, ngenxa yokuba ngeli xesha ixesha le-placenta livuthwa ngokuziphatha kakuhle, ngokuthatha inxaxheba ephambili kwimveliso ye-hormone yokukhulelwa, eyenziwa ngaphambi komzimba ophuzi. Into efana ne-toxicosis yokuqala ibangelwa ngumsebenzi we-hormonal yomzimba ophuzi ngaphambi kweveki le-12 yokukhulelwa. Ngoku ezi zinto zibuthathaka okanye zinyamalale, nangona zingekho zonke. Ikhefu liya kuba nokukhulelwa okuphindaphindiweyo, ukukhulelwa okunzima kunye nokukhulelwa kokuqala.
Yintoni ibhekwe ibonakala ngathi kwiiveki ezili-12?
Kwiiveki ezili-12, i-embryo sele ifana nekopi encinci yomntu-inezitho ezisisiseko kunye neenkqubo-ingqondo kunye nomgudu womgogodla, ityhubhu yamathumbu, intliziyo kunye nenani elincinci lemithambo yegazi, isibindi kunye neentso zisele zisebenza, ukuveliswa kwe-bile yokuqala kunye nomchamo kuqala. Ngelo xesha, i-skeleton ikhula-i-muscle, i-squtilaginous squke, i-skin incogument. Umbungu uqala ukwenza ukunyakaza okungazibandakanyeki - kudla umnwe, kushukumise intloko, kwenza ukuba uhambelane kunye nezixhobo kwaye unokubakho ukusa. Inkqubo yesantya yengane ezayo iyaqhubeka iguqukela, kodwa ingqondo sele ifana nengqondo yomntu omdala, kuphela kwinguqu encinane. Ubungakanani be-fetal kwiiveki ezili-12 bufaniswa nobukhulu beqanda eliphakathi kwenzaka. Ukukhula kwe-Fetal kwiiveki ezili-12 kuyahlukahluka ukusuka kwi-6 kuya kwi-9 cm.
I-TVP okanye ubukhulu bendawo ye-collar fetal kwiiveki eziyi-12 yenye yeendlela zokuhlola ukuchithwa kwe-chromosomal pathology. Ngokuqhelekileyo, i-TVP ithathwa njengeyi-3 mm, kwixabiso eliphakamileyo kunconywa ukwenza i-chorion biopsy yokuxilongwa kwe-chromosomal engafanelekiyo, ngokukodwa, isifo se-Down. Nangona kunjalo, akuqhelekanga kubantwana abanempilo enempilo ukuba bazalwe nge-TVP 5 mm okanye ngaphezulu.
I-Fetometry ye-fetus kwiiveki ezili-12 kuyimfuneko ukuzimisela ngokuchanekileyo kwiminyaka yobudala, ukubeka iliso ukuphuhliswa kwengane, kunye nokuvavanya ukuphazamiseka okubonakalayo ekuphuhlisweni kwembungu.
Ubungakanani beBPR okanye ubukhulu biparietal yentloko ye-fetal kwiiveki eziyi-12 kufuneka ubuncinane ubunzima buka-21 mm, i-LJ okanye i-circumference - engaphantsi kwama-26 mm, i-KTP okanye ubungakanani beparietal - engaphantsi kwe-60 mm, i-DB okanye ubude besikhumba - engaphantsi kwe-9 mm, iDHA okanye ububanzi besifuba - kungekhona ngaphantsi kwama-24 mm.
Indlela yokuziphatha kumama ozayo ngexesha leeveki ezili-12?
Umntwana uhamba kakhulu kwiiveki ezili-12 ukuya kwe-13 ukuya kwe-13, uguqula i-amniotic fluid ngenkuthalo, uhambisa izibamba kunye nemilenze, ahluke ngokucacileyo ama-marigolds kwi-handles, i-peristalsis ibonakala emathunjini. Ngokuphathelele umama wesikhathi esizayo, ubukhulu bombele buya kwanda - buqala ukuphakama ngaphezu kweeplastiki ezincinci, kodwa akukho mfuneko yokugqoka iimpahla kubasetyhini abakhulelweyo. Kubalulekile ukuba ukhumbule ukuba iimpahla kufuneka zikhululeke kwaye kungabikho nhlobo. Ekubeni uxinzelelo kumathumbu luyanda kunye nokwanda kwendawo yokubeleka, kunye nokuqhawulwa kungavela ngexesha lokukhulelwa , kubalulekile ukuphucula ukutya kwakho kunye nokutya okunothile kwifiber - zonke iintlobo zemifuno eluhlaza, izityalo - i-oats, i-buckwheat, i-millet. Nangona kunjalo, irayisi ezimhlophe zimele zifinyeleleke, njengoko zilungisa kwaye ifom ephosiweyo iqukethe amavithamini ambalwa.
Ngelo xesha, oogqirha bacebisa ukunciphisa ukutya kweemveliso zenyama, apho kunokwenzeka khona
Kwakhona, umama wesikhathi esizayo uya kuba luncedo ngakumbi ukuba abe emoyeni rhoqo, kwaye uqhubele phambili, kuba oku kunceda ekuphuhliseni imisipha yamathambo kwintsana kwaye iya kwandisa ukuphuma kwe-oksijini kwizicubu zakhe.
