I-placenta kulo lonke ukukhulelwa iqala futhi idlule ngezigaba eziningana zokuvuthwa. Esikhathini samasonto amabili kuya kwangu-30 sisesiteji sonyaka - isikhathi sokuthuthukiswa. Kusukela kuma-30 kuya ku-33 amasonto i-placenta ikhula, futhi le nkathi ibizwa ngokuthi isigaba sokuqala sokuvuthwa. Isikhathi sesibili sokuvuthwa kwe-placenta ngamaviki angu-33-34. Emva kwamasonto angu-37 i-placenta iguga - isigaba sesithathu sokuvuthwa.
Isiqu sokuvuthwa kwe-placenta sinqunywa yi-ultrasound. Futhi ngezinye izikhathi udokotela uthola ukuguga ngaphambi kwesikhathi eside kwe-placenta. Kungani lokhu kwenzeka?
Yini ebangela ukuguga ngaphambi kwesikhathi se-placenta?
Kunezizathu eziningana zokuvuthwa ngaphambi kokuqala kwe-placenta. Phakathi kwabo:
- ngokweqile noma, ngokuphambene, isisindo somzimba esanele sokwesifazane okhulelwe;
- ukutholakala kwezifo ezingapheli, isibonelo, isifo sikashukela, isifo sezinso, isibindi, uhlelo lwe-urogenital;
- ukukhipha isisu nokukhulelwa okunzima nokubeletha ku-anamnesis;
- umonakalo owenziwe ngomshini esibelethweni;
- isifo se-circulatory system (ukuphazamiseka kwegazi kanye nezinye);
- izifo ezithathelwanayo ngesikhathi sokukhulelwa;
- ukubhema, ukuphuza utshwala, izidakamizwa;
- i- toxemia enamandla ekukhulelwe kokuqala ;
- i-gestosis;
- i-rhesus-impikiswano.
Yini esongela ukuguga kwasekuqaleni kwe-placenta?
Umphumela walesi simo kungenzeka kube ukwephulwa kwegazi ku-fetus. Ngenxa yalokhu, ngeke athole i-oxygen nezakhi. Ngenxa yalokho, i-hypoxia kanye ne-hypotrophy (isisindo esiphansi) singakhula.
Ngaphezu kwalokho, ukuguga kusenesikhathi ngaphambi kwe-placenta kusongela ukuthuthukiswa kwengane ye-brain pathologies, ukukhishwa kokuqala kwe-amniotic fluid, ukuthungathwa kwangaphambi kwesikhathi kwe-placenta nokukhulelwa kwesisu.
Ukuze kuvimbele lokhu, kuyadingeka ukudlulisa zonke izivivinyo ezidingekayo ngesikhathi esifanele futhi, lapho ubona izinkinga nge-placenta, ukuthatha ukwelashwa okubekiwe.
