I-placenta kulo lonke ukukhulelwa likhula kwaye lidlule kwiinqanaba eziliqela lokukhula. Ngexesha elide ukususela kwiiveki ezi-2 ukuya kwe-30 kwinqanaba le-zero-ixesha lophuhliso. Ukususela kwiiveki ezingama-30 ukuya kuma-33 i-placenta ikhula, kwaye eli xesha libizwa ngokuba ngumgangatho wokuqala wokukhula. Ixesha lesibini kwisikolo sokukhula kwepentecenta iiveki ezingama-33-34. Kwaye emva kweiveki ezingama-37 i-placenta iguga - isigaba sesithathu sokukhula.
Isiqhamo sokukhula kwe-placenta senziwa ngu-ultrasound. Kwaye ngamanye amaxesha ugqirha ufumanisa ukuguga kwasekuqaleni kwephacenta. Kutheni oku kwenzekayo?
Yintoni ebangela ukuguga kwangaphambili kwepentecenta?
Kukho izizathu ezininzi zokuvuthwa kwangaphambi kwepentecenta. Phakathi kwazo:
- ngokugqithiseleyo okanye, ngokuchaseneyo, ubunzima bomzimba obunelungelo lomfazi okhulelweyo;
- ubukho bezifo ezingapheliyo, umzekelo, isifo sikashukela, isifo sesifo, isibindi, inkqubo ye-urrogenital;
- ubukho bokukhupha isisu nokukhulelwa okunzima kunye nokubeletha kwi-anamnesis;
- umonakalo otyunjelwayo kwisibeleko;
- ukukhubazeka kwenkqubo yokujikeleza (ukuphazamiseka kwegazi kunye nabanye);
- izifo ezithathelwanayo ngexesha lokukhulelwa;
- ukutshaya, ukusela utywala, iziyobisi;
- i- toxemia enzima ekukhulelweni kokuqala ;
- gestosis;
- i-rhesus-conflict.
Yintoni eyongela ukuguga kwasekuqaleni?
Isiphumo salesi siqhamo sinokuphulwa kwegazi kwi-fetus. Ngenxa yoko, akayi kufumana i-oxygen kunye nezondlo. Ngenxa yoko, i-hypoxia kunye ne-hypotrophy (isisindo esiphantsi) sinokuphuhliswa.
Ukongezelela, ukuguga kwangaphambili kwipentecenta kusongela ukuphuhliswa kwengqondo yengqondo yengqondo, ukukhutshwa kwangaphambili kwe-amniotic fluid, ukutshatyalaliswa kwangaphambili kwipentecenta nokukhulelwa kwesisu.
Ukuze uthintele oku, kuyimfuneko ukudlulisa zonke iimviwo eziyimfuneko ngexesha elifanelekileyo kwaye, xa uchonga iingxaki kwi-placenta, ukuthatha unyango olumiselweyo.
