Abesifazane abaningi emva kwe-ultrasound besabisa isiphetho sokugcizelela ukuthi odokotela basezintanjeni banezintambo ezimbili esikhundleni sezintathu, njengoba kulindeleke. Odokotela abanikezi ngaso sonke isikhathi ulwazi oluningiliziwe, futhi omama abazayo bayakhathazeka kakhulu ngemibuto - yini engayenza kumntwana nokuthi yini engenziwa ukuze ugweme imiphumela. Izitsha ezimbili emgqeni we-umbilical - lokhu kuyi-anomaly evamile, umphumela ongase ube yizinkinga ze-fetus, ngokuvamile inhliziyo ihlupheka.
Zingaki izitsha okufanele zibe nomtholampilo?
Intambo yomzimba (intambo ye-umbilical) iyisitho esithinta i-fetus ngomzimba womama, sifinyelela ubude buka-50-70 cm noma ngaphezulu. Insimu yomzimba kufanele ibe nemikhumbi emithathu, okungukuthi: imishanguzo emibili kanye nomvuthwandaba owodwa. Nge-aplasia (ukuthuthukiswa okungalungile) komunye umthambo wezintambo zomzimba, kuvela okungavamile - intambo yomzimba 2 yomkhumbi, okungukuthi. umshini owodwa nomvini owodwa. I-artery ithwala igazi le-fetal, ligcwele i-carbon dioxide kanye nemikhiqizo ye-waste metabolism kumaplascenta omama. I-vebilical vein ithwala igazi, elicebile nge-oksijeni kanye nezakhi, kusukela emaphaketheni omama kuya emntwaneni. Ekubelethweni, imikhumbi engu-2 emthonjeni we-umbilical ungabangela i-hypoxia ye-fetal, ngakho-ke isigaba se-caesarean siboniswa ezimweni ezinjalo. Ngesikhathi sokubeletha, umntwana kudingeka adluliselwe kakhulu, njengoba ukugeleza kwegazi kungaphazamiseka lapho kunquma intambo yomzimba.
Ngesikhathi sokukhulelwa kuyadingeka ukuthi kubonakale ukuthi izakhi zofuzo zikhishwe ukungalingani kwe-chromosomal (udokotela uvame ukusikisela ukwenza i-cardocene - ukuhlolwa kwegazi okwenziwe entanjeni). Futhi kuze kube amasonto angu-24, udinga ukwenza i-ultrasound yenhliziyo ye-fetal (ukuvimbela isifo senhliziyo esingahle) kanye ne-ultrasound enwetshiwe yazo zonke izitho. Ukuze kuvinjelwe ukwephulwa, odokotela bakhetha i-CTG ne-doppler ye-bi-masonto onke.
Ukuzivocavoca kubonisa ukuthi inani lezinsimbi zomtholampilo ezingavamile alithinta impilo engcono yengane. Futhi ukubeletha kwengane ngokuphambene nalesi simo cishe kuyinto ehlukile: empilweni yokuphila kwengane, isitha esisodwa asinandaba.
