Okufanelekile, ngesikhathi sokukhulelwa, i-placenta inobuningi obuthile, elawulwa yiviki. Ngakho-ke ngeviki elingama-22 kwesikhashana ubukhulu bendawo yengane kufanele kube ngu-3.3 amentimitha. Emasontweni angu-25, landa ngamamitha angu-3.9, futhi kakade emavikini angu-33 okukhulelwa, ubukhulu be-placenta bubungamamitha angu-4.6.
Lapho i-placenta ekhudlwana ibonakala ngesikhathi sokukhulelwa, lokhu kungabonisa ukutheleleka kwe-intrauterine ye-fetus. Kulesi simo, kubalulekile ukudlulisa ukuhlolwa kwegazi nge-toxoplasmosis noma i-cytomegalovirus.
Uma owesifazane okhulelwe ene-placenta eyimbi kunayo evamile, khona-ke owesifazane ubhekwa ngumchwepheshe futhi uyithumela ku-ultrasound ne-CTG. Kungenxa yezivivinyo ezinjalo kuphela ongakwazi ukunquma ngokunembile ukutholakala noma ukungabikho kwe-pathologies enganeni.
Izimbangela ze-placenta elikhulu
Izimbangela ezithinta ukuqina kwe-placenta zingaba kanje:
- izifo zegciwane;
- izifo ezithathelwanayo;
- i-rhesus-impikiswano ekukhulelweni ;
- umama wesifo sikashukela;
- i-anemia enkulu;
- usongo lokukhulelwa kwesisu;
- ukukhulelwa okuningi;
- i-gestosis;
- ngokweqile noma ukuntuleka kwesisindo sowesifazane okhulelwe.
Imiphumela ye-placenta encane
Lapho indawo yengane iba yimbi, izibalo zibonakala zithinta ukusebenza kwe-placenta. Ngenxa yenkambiso enjalo, i-fetus ayitholi i-oxygen eyanele, futhi lokhu kuyathinta ukuthuthukiswa kwayo kwe-intrauterine. Ngaphezu kwalokho, ngenxa yokukhukhumeza kwe-placenta, umsebenzi wayo we-hormonal wehla, okwesabisa ngokuqedwa kokukhulelwa noma kokubeletha ngaphambi kwesikhathi.
Ezimweni ezinzima zokuqina kwe-placenta, ukufa kwangasese kokubeletha kanye nokuthungatha isikhathi esingaphansi kwe-placenta kungenzeka. Ukuze ugweme imiphumela emibi, udokotela ubeka ukuhlolwa okungeziwe ngokushesha nje lapho esolwa nge-placenta egxilile. Uma ukwesaba kwakhe kuqinisekiswa, khona-ke ngokushesha waphatha lesi sifo.
