Ukuvuthwa kwe-placenta kungenye yezinkomba ze-placenta nokuntuleka kwe-placental. Ikuvumela ukuba uhlole izinguquko zomzimba kanye nezifo ezingeni le-placenta, kuqala nge -2 trimester yokukhulelwa .
Ukukhula kwe-placenta ngesonto
Okokuqala udinga ukuqonda - yini izinga lokuvuthwa kwe-placenta? Ngokujwayelekile, ukuvuthwa kwe-placenta kuyinkqubo yemvelo ngokuphelele. Kuyadingeka ukuze uhlinzekele ngokugcwele futhi ngesikhathi esifanele ukuhlinzeka izidingo zobusana obukhulayo. Kunezinyathelo ezine zokuvuthwa kwe-placenta ngaphansi kwezimo zokukhulelwa okuvamile.
Ngakho, ukuvuthwa kwe-placenta amasonto:
- i-zero degree - ihlala njalo kuze kube sevikini le-30 lokukhulelwa. Kulesi simo i-placenta inesakhiwo esingafani nakancane;
- i-degree lokuqala - ibonakala ngesikhathi sokusukela ngesonto lama-27 kuya ku-34 lokukhulelwa. Ngokwesilinganiso, lesi sifo sokuvuthwa kwe-placenta kubonakala emavikini angu 32-33. Kulesi simo, iziqu ezihlukile ze-echogenic zibonakala emathisini we-placenta, futhi i-chorionic plate ithola ifomu elincane;
- i-degree yesibili ibonakala kusukela ku-34 kuya ku-39 ngesonto. Okusho ukuthi uma sekufika amasonto angama-36 ngemiphumela ye-ultrasound ufakwa i-degree yesibili yokuvuthwa kwe-placenta - lokhu kuyinto evamile. Ukuchithwa kwekhabethe le-chorionic kwanda futhi kufakwe iziqu eziningi ezilinganiselwe zokuphakama kwamasayizi amancane;
- i-degree yesithathu itholakala ngemuva kwamaviki angu-37. Kuboniswa ukuhlukumeza okukhulu kwe-plate chorionic kanye nesakhiwo se-lobate se-placenta ngokwayo.
Ukuguga kokugcina kwe-placenta kwenzeka ekupheleni kokukhulelwa. Ngesikhathi esifanayo, iba yindawo encane endaweni, izindawo zendawo yokuthutha usawoti zivela kuwo.
Ubukhulu kanye nezinga lokuvuthwa kwe-placenta
Ubukhulu be-placenta ngenye yemingcele lapho izinga lokuvuthwa kwalo lizimisele khona. Ubukhulu bunqunywe engxenyeni enkulu kakhulu ye-placenta, lapho usayizi wayo ubukhulu khona. Le nkhomba ikhula njalo kuze kube sekupheleni kwamasonto angu 36-37 cishe ngo 20-40 mm.
Ngemuva kokuqala kwamasonto angu-37, ukuqina kwe-placenta kuqala ukwehlisa noma ukuyeka kudijithi yokugcina.
Ukuguga kusengaphambili kusendaweni ye-placenta
Uma izinga lesithathu lokuguga livela ngaphambi kwamasonto angama-37 okukhulelwa, umbuzo wokuguga kusenesikhathi ngaphambi kwe-placenta nokungaqiniseki kahle. Kulesi simo, owesifazane nomntwana kumele baqaphele njalo isimo.
Izimbangela zokuguga ngaphambi kwesikhathi se-placenta: lokhu kungaba umphumela wokutheleleka kwe-intrauterine, ukuphazamiseka kwe-hormonal, i-gestosis, usongo lokukhulelwa kwesisu, ukuphuma kwegazi emzimbeni wokuqala, ukukhulelwa okuningi. Futhi, ukuvuthwa kwe-placenta kungadlula imigomo ye-Rh-impikiswano phakathi kowesifazane nomntwana nesifo sikashukela somama.
Enye inkomba ehlolwa ngesikhathi se-ultrasound yindawo yokunamathiswa kwe-placenta. Kuhle uma i-placenta inamathele edongeni eliphansi noma elingaphakathi kwesibeletho eduze naso phansi (ingxenye engenhla ephikisana nentamo). Kule ndawo i-placenta iyasebenza
Kubuye kwenzeke ukuthi i-placenta ifakwe endaweni yomphimbo - lesi sikhundla sibizwa ngokuthi i-placenta previa. Owesifazane kulokhu uboniswa ukuphumula kombhede nokuphumula ngokomzimba kuze kube sekupheleni kokukhulelwa. Ngendlela, iphelela ezimweni eziningi ngokusebenza kwesigaba se-cearean.
Uma i-placenta inamathele phansi, ngesikhathi sokukhulelwa, ezimweni eziningi, "ihanjiswe" phansi kwesibindi. Uma lokhu kungeke kwenzeke, kunengozi yokuphuma kwindlela yokulethwa. Kulesi simo, udinga ukulungele isigaba sokuphepha esiphuthumayo.
