Ixesha lokubanjwa kwindoda ibhinqa iiveki ezingama-38 ukususela ngexesha lokukhulelwa. Kwinkoliso yabasetyhini, ukukhulelwa kuthatha iintsuku ezingama-266. Kodwa akunakwenzeka ukubala usuku lokuzalwa kwangaphambili kuze kube yimini ngaphambi. Kuninzi kuxhomekeke kwimvelaphi ye-hormone yowesifazane, ihamba nezifo zomama kunye nesisu, isondo kunye nesisindo somntwana ongakazalwa, njl. Kodwa emva kweeyure ezingama-37 zokukhulelwa umntwana ulungele ubomi bobucala (i-term full). Emva kwesi sihlandlo umntwana ozelweyo usebenza ngokupheleleyo.
Kodwa umntwana emva kweeveki ezingama-42 zokukhulelwa uthathwa njengobandezeleka , kwaye abasebenzi banokuhamba kunye neengxaki ezinzulu kumntwana. Ngako oko, ixesha lokukhulelwa kubalulekile ukungazi kangangoko umhla wokuzalwa, kodwa kunokuba ukwazi ngexesha lokuzalwa komfazi kuya kuthathwa njengesiqhelo, kunye nexesha elipheleleyo lomntwana.
Ixesha lokukhulelwa komngcipheko kunye neengxaki zomntwana
Isikhathi sokukhulelwa sisithuba seeveki ezingama-40, kwaye i-embryonic pregnancy period i-38. Ukuthotyelwa komzimba kuqala ngomhla wokuqala wenyanga yokugqibela. Ixesha lokumama liqala ukususela kumhla wokukhulelwa (ukususela ngomhla wokuvuthwa, okuqhelekileyo kuza ngomhla we-14 ukusuka ekuqaleni kwenyanga kunye kunye neentsuku ezi-4).
Unokubala njani ukukhulelwa komzimba?
Ukukhulelwa kwesigxina kunye nokunyanisekileyo (ukumbumba) ukukhulelwa kuyahluka kwiiveki ezimbini. Ngokwenza oko, ixesha le-embrionic lingaqwalaselwa kwaye lilinganiselwe ukubala kuphela umgqithisi. Ukuba ibhinqa ayifuni kuphela umhla wokuqalisa kokuya esikhathini, kodwa nomhla wokukhulelwa, imida yokukhulelwa ichanekile ngakumbi. Ixesha lokubanjwa kwesigxina lihlala kwiintsuku ezingama-280 ukususela ngosuku lokuqala lwenyanga yokugqibela. Ngokweziphumo ze-ultrasound, ngokwetafile, kuqinisekiswa ukuba umntwana ohambelana nomntwana uyangqinelana ne-obstetric, kodwa ayiyi-embryonic.
Ngaba ndiyakwazi ukubala umhla wokuzalwa komgca wokukhulelwa?
Indlela elula yokubala umhla ozalindelekileyo wokuzalwa ingaqwalaselwa oku kulandelayo: ukususela ngomhla wokuqala wokugqibela wenyanga wongeza iintsuku ezingama-280 (ifom yeKeller). Nangona kunjalo, ngokwenza oko kunzima kwaye umhla wokuzalwa ungasetyenziswa ngeendlela ezimbini ezifanayo.
- Ngomhla wokuqalisa kwenyanga yokugqibela, iinyanga ezithoba kunye neentsuku ezisixhenxe zongezwa.
- Ukususela ngomhla wokuqala kwenyanga yokugqibela, inyanga ezintathu zithathwa kwaye iintsuku ezisixhenxe zongezwa.
Iiveki ukususela kumhla wokuqala wesithanga sokugqibela. Ukuze kulungele ugqirha, iiveki ezingama-40 zisabelana ngokwemigangatho emithathu. I-trimester eyi-1 iquka iiveki ezi-1-14 zokukhulelwa, i-2 trimester - iiveki eziyi-16-28, kunye ne-3 trimester-ukusuka ku-29 ukuya ku-40.
Isithintelo sokubambisana kunye nexesha le-ultrasound
Akukokuchaneka ukucinga ukuba i-ultrasound igqitywe ngumzimba wesigxina okanye u-embryonic gestation. Kunoko, ngokuchasene noko, ngokwetafile ezikhethekileyo, apho ubukhulu bomntwana obuncinane bomntwana obuthatywayo bwenzelwe ukuthatha iiveki zokukhulelwa, uzimisele ukuthobela ukukhulelwa kwabo. Ngokuqhelekileyo ubukhulu bomntwana bufane nexesha lokunciphisa kunye kunye neveki enye: umntwana ukhula ngokuqhelekileyo. Ukuba i-term for ultrasound ingaphantsi kwe-obstetric, oku akuthethi ukuba i-obstetric term ibalwa ngokungafanelekanga, kodwa into ekhusela ukuveliswa okuqhelekileyo komntwana. Iimbangela eziphambili zokulinda kwe-intrauterine ukukhulelwa kuku:
- ukugula komama;
- ukuphulwa komsebenzi oqhelekileyo we-placenta;
- ukukhulelwa okubanzi;
- i-chromosomal engafanelekanga yomntwana;
- izifo zengqondo;
- imikhwa emibi yomama;
- ukungondleki kakuhle, njl
Ukuba i-term for ultrasound yinto engaphezu kwesithintelo, ngoko ngokuqhelekileyo imbangela iya kuba sisisindo esikhulu somntwana ongakazalwa (ngenxa yobushushu, isifo sikashukela, ukunyusa ukudla komama ngexesha lokukhulelwa).
Kungenzeka ukuba umhla wokugqibela wesithandathu unqunywe ngumfazi ngokungafanelekanga kwaye ukuba uyayikhumbula umhla wokuzala , kungcono ukubala ixesha le-obstetric ngokusebenzisa umbryonic, ungeze kwiiveki ezimbini zokugqibela.
