Kwiveki yesi-21 yokukhulelwa, umama omele ulindele ukuba abe ne-dopplerometry ye-strings. Olu pho nonongo luqhutyelwa ukuchonga inani leenqanawa zentambo kunye nokufumana izibonakaliso zemathematika zegazi. Kubalulekile ukuchonga ukukhulelwa kwamathuba okukhulelwa kunye nophuhliso lomntwana.
Ngokuqhelekileyo kwenzeka, loo ndinyana yesi sivivinyo ihamba kunye namava anamandla omama ozayo. Ngelishwa, oogqirha badla ukunika isigulane (kwimeko yethu-isigulane) isiphetho esinomfanekiso omile, ngaphandle kokuchaza nantoni na. Kubalulekile ukuba lo mfazi azifunelele ngokuzimeleyo iimpendulo zemibuzo: bangaphi, ngokwenene, ukuba intambo ibe nekhanda lomthi kwaye kufuneka basebenze njani, le mikhumbi yomtya. Siza kuzama ukucacisa kangangoko kunokwenzeka.
Inani leenqanawa kwintambo yomlomo
Intambo yomzimba luhlobo 'lwetambo' oludibanisa umzimba womama kunye nomntwana, okanye ngokuchanekileyo, iinkqubo zabo ezijikelezayo. Ngokuqhelekileyo, intambo yomthi ineemikhumbi e-3: i-vein 1 kunye nemibhobho emibili. Nge-vein, igazi elenziwe nge-oksijini enezondlo ezivela emzimbeni kamama ngaphakathi kwephacenta lingene egazini lomntwana, kwaye kunye nemibhobho, igazi kunye neemveliso zobomi bexesha elizayo umntwana uya kwi-placenta aze afike emzimbeni kamama.
Ziziphi iimpazamo ezivela kwimimiselo?
Kwi-0.5% ye-singleton kunye ne-5% yokukhulelwa okuphindaphindiweyo, oogqirha baxilonga "i-EAP" (yodwa umthamo wentambo yomlomo). Oku kuthetha ukuba kulo mzekelo intambo yomthi inemikhumbi e-2 endaweni ye-3.
Ukungabikho komnye umthambo ungowokuqala, okanye uphuhliswe ngexesha lokukhulelwa (oko kukuthi, kodwa kwasulwa kwaye yayeka ukwenza umsebenzi wayo). Isifo sikashukela kubasetyhini abakhulelweyo sandisa amathuba e-EAP.
Ngaba kuyingozi?
Uninzi lwamagqirha akholelwa ukuba i-EAP ingaba ngummakishi wezinto ezingekho phantsi kwe-chromosomal. Kule meko, ukuhlolwa kokubeleka kufuneka kuwandiswe, ukwenzela ukufumanisa ukungalunganga komntwana. Oku kuthetha ukuba, ngaphezu kwe-EAP, ukuhlolwa kwe-ultrasound kubonise ukuba kukho nayiphi na imiphumo yesifo sokuzalwa komntwana okanye i-fetal anomalies, kunokwenzeka ukuba (malunga ne-30%) yokuba umntwana lowo unomdla wokungaqheleki. Xa ukhunjulwa nge-chromosomal anomaly, kubalulekile ngexesha lokukhulelwa ukwenza ngokuphindaphindiweyo ukuqhutyelwa kweDoppler yokuhamba kwegazi kwintsimbi yomtya. Ukulinganiswa kwegazi lokujikeleza kwegazi kwi-artery embilical ngokuchaneka kwe-76-100% ivumela ukubikezela ukuba khona okanye ukungabikho kokungaqhelekanga kwintuthuko yomntwana.
Kwimeko ezininzi (i-60-90% yokukhulelwa) kweemeko ze-EAP yi-defect yangasese (engahambisani nezinye izinto ezingaqhelekanga), kwaye akuyingozi. Kakade, umthwalo kwisitya esinye sininzi, kodwa omnye umzobo uvame ukuphatha kakuhle umsebenzi wayo. Kuphela kwi-14-15% yamatyala, ubukho bomthi omnye ubeka umngcipheko wokuzalwa komntwana omncinci.
Ayinayo impembelelo enkulu kwinkqubo yokuzalwa. Ukuba ugqirha ohamba phambili kunye nombelethisi uyaziswa ngesiphene esele sikhona, akukho nto ibangela ukukhathazeka. Unokuqiniseka ukuba ugqirha ofanelekileyo uya kukhetha iindlela ezifanelekileyo zokuqhuba umsebenzi, oya kuqinisekisa ukhuseleko lomama nosana kunye nomphumo okhuselekileyo wabasebenzi.
