Chiwalo chachikulu mu thupi lazimayi pa nthawi ya mimba ndi placenta. Zimatsimikizira ntchito yofunikira ya mwana wosabadwayo, yomwe imayika pakati pa mayi ndi mwana, imateteza ku matenda, imapereka mpweya. Pomaliza, malo a mwana (omwe amatchedwanso placenta) amapangidwa ndi mapeto a trimester yoyamba.
Kugwirizana ndi kuyendetsa bwino kwa placenta kumakhudza mwachindunji njira yachibadwa yoberekera ndi kuthetsa kwake bwino. Kawirikawiri, placenta iyenera kugwiritsidwa pansi pa chiberekero (khoma lalitali). Koma pali zifukwa pamene malo okhudzidwa ali pansi pa 6cm kuchokera ku uterine mmphepete, malowa akutchedwa otsika kwambiri pa placenta.
Zifukwa za chigawo chochepa cha placenta
Chombo chochepa cha placenta chikhoza kukhala zotsatira zake:
- Ntchito yoyambitsa opaleshoni pachiberekero (kutaya mimba, kuchotsa mimba);
- uterine fibroids ;
- Gawo la Kaisareya;
- multiple pregnancy;
- kusuta;
- amaphunzira maphunziro ndi kulowetsa mu uterine.
Komabe, sikoyenera kuopsezedwa ngati pa sabata la 20 la mimba ndi chithandizo cha ultrasound chida chochepa cha placenta chinatsimikiziridwa. Malo a mwana akhoza kutchedwa chiwalo chosamuka. Ndi kuchuluka kwa nthawi ya mimba, ikhoza kusintha malo ake. Ndipo ngati, mwachitsanzo, pa masabata makumi awiri muli ndi chigawo chochepa cha placenta, ndiye pamasabata 22 chikhoza kukhala chachilendo. Kawirikawiri, amayi 5% okha okha omwe ali ndi chikhomo chotsika pansi amakhalabe pamalo amenewa kwa masabata makumi awiri ndi awiri. Ndipo pamene gawo limodzi mwa magawo atatu a 5% amakhala mpaka masabata 37.
Ndipo komabe, mgwirizano wotsika wa placenta mu sabata la 22 la mimba uyenera kulimbikitsa amayi oyembekezeka kuti azisamalira thanzi lake komanso thanzi la mwana wake.
Kumalo otsetsereka kotsika kumakhala kosiyanasiyana:
- Pamene placenta imangokhala yotsika, koma sichipezeka ndi uterine pharynx;
- Pamene placenta ili pansi ndipo imachepetsa pang'ono pharynx - ichi chimatchedwa kusakwanira kufalitsa;
- ndipo ngati muli ndi chiberekero cha uterine, timakhala ndi placenta previa .
Kodi ndichite chiyani ndi chida chochepa cha placenta?
Kuchiza kwa chigawo chochepa cha placenta panthawi imeneyi pakukula kwa mankhwala athu kulibe. Chombo chochepa cha placenta chimatanthauza kuti muyenera kutsatira mimba mwatcheru. Onetsetsani kuti zakudya zamtundu ndi mpweya zimaperekedwa kwa mwanayo. Pamene pali ululu kapena kupweteka, nthawi yomweyo pitani ambulansi, chifukwa chakuti malo a mwana akhoza kutsegulidwa. Pokhapokha ngati pali nkhani yeniyeni, mwayi wokhala ndi ufulu wodzipereka payekha wazimayi sungapezeke. Ndizokonzekera mwapadera kwa gawo la kansera. Popeza malo otsika kwambiri a placenta amatha kumuopseza mkazi popanda china chilichonse kupatula kuwonongeka kwa magazi.
