I-placenta iyisici esiyingqayizivele esisiza ingane ukuba ikhule, ithuthukise, yamukele zonke izakhi ezidingekayo ngisho ne-oxygen. Idlula indlela yentuthuko kusuka kugobolondo elincanyana (i-chorion) kuya emgqeni omanzi obeka isikhumba sesibeletho. Njengoba i-placenta ebaluleke kakhulu ekuthuthukiseni ingane, odokotela bayayinaka kakhulu. Hlukanisa amadigri amaningana okuvuthwa kwe-placenta , okuyinto idlula ngokukhulelwa okukhulayo.
Izinga lokuvuthwa kwe-placenta
I-placenta ikhiwa cishe ngeviki le-12 futhi ithatha imisebenzi yokunakekela ingane nokulawula isizinda se-hormonal yomama. Ngakho-ke i-placenta isendleleni yokushintsha, ivumelanisa nezidingo zengane. Ngesikhathi sokuhlola i-ultrasound, eyenziwa emavikini angu-20 no-32, noma ngokuphindaphindiwe, ngokusho kwezinkomba, ochwepheshe bahlola ngokucophelela izinga lokuvuthwa kwalo. Iqiniso liwukuthi ushintsho alukwazi nje ukuthi lusemvelo, luphiko, kepha lubuye lungabonakali. Kulesi simo, kwenziwa isinqumo ekusetshenzisweni kwezidakamizwa noma kwezidingo eziphuthumayo.
Isigaba sokuvuthwa se-placenta sinqunywa kanjani?
I-placenta yabesifazane abakhulelwe inesakhiwo esithile, esihlolwe yi-ultrasound. I-Zero degree yokuvuthwa ihambelana ne-placenta, enesakhiwo esivumelanayo esingenakho okufakiwe. Njengomthetho, i-placenta enjalo ibonakala kusukela ekuqaleni kwe-trimester yesibili iphinde iphele amasonto angu-30. Kodwa-ke, ngasekupheleni kwamasonto angu-27, izinguquko esakhiweni se-placenta zingase zenzeke, ukutholakala kwe-echogenic kuvele, ukukhanya okuncane kuphawulwe. Lona i-placenta yebanga lokuqala. Kancane kancane ku-placenta, kuguqulwa izinguquko eziningi nakakhulu, ukukhuphuka okukhulu nokunciphisa okuncane. Kuseduze kokubeletha, cishe amasonto angama-37-38 okukhulelwa, i-placenta ithola isakhiwo se-lobular, kunezingosi zokufaka usawoti, lokhu kuyizinga lokuvuthwa kwesithathu. Uma izinga lokuguqula ezakhiweni alihambisani negama, khona-ke ukuvuthwa ngaphambi kokukhula kwe-placenta kuyatholakala.
I-degree yokuqala yokuvuthwa kwe-placenta
Ngezinye izikhathi, uma isimo sibonakala singabazeki, isazi se-ultrasound protocol singabhala izinga lokuvuthwa kwe-placenta 0 1 noma ukuvuthwa kwe-placenta 1 2. Uma isikhathi sisezinhlangothini zamazinga ahlukene wokuvuthwa, lesi simo sivamile. Uma isikhathi sisencane kakhulu, umbelethisi ogcina ukukhulelwa kwakho uzothatha zonke izinyathelo zokunciphisa ukuvuthwa kwe-placenta, kanye nokuqapha ngokucophelela isimo somntwana. Ngaphezu kwalokho, kubalulekile ukuhlola isimo sokugeleza kwegazi okuphazamiseka kwegazi, lokhu kuzoqinisekisa noma ukuphika ukuxilongwa.
Noma kunjalo, ukuvuthwa kwe-placenta 1 kuvumela ukuthi ingane ihlinzekwe kahle izakhi futhi ngokuvamile kulesi sigaba ukuvuthwa ngaphambi kwesikhathi kudinga ukubonwa kuphela. Ku-ultrasound elandelayo, umama uzohlola ukuvuthwa kwe-placenta futhi, uma kunesidingo, ulungise uhlelo lwemithi yokwelapha.
Kukhona isimo esivumelana nayo, kamuva ukuvuthwa kwe-placenta, akuncane kakhulu, kepha noma kunjalo uma i-placenta isesiteji sokuqala ngemva kwamasonto angu-34-35, ochwepheshe bangasolwa ngokuphulwa ekuthuthukiseni umntwana, kanye nezinkinga empilweni yomama. Lesi simo sidinga ukuhlolwa okwengeziwe.
Ukuvuthwa kwe-placenta kuyahlukahluka ngokwanele, futhi i-ultrasound iyindlela yokuhlola ephansi. Kodwa-ke, uma kukhona ukusola kokuvuthwa okusheshayo noma kokuphuza kwesikhathi se-placenta, kudingeka uphinde uhlole ukuxilongwa, wenze izifundo ezengeziwe, futhi uma kunesidingo - ukwelashwa. Lesi yisiqinisekiso sempilo yengane.
