I-placenta eludongeni lwangaphakathi lwesibeletho: okujwayelekile noma ukukhubazeka?

I-placenta iyisici esibalulekile esakhiwa futhi sikhula kuphela ngesikhathi sokukhulelwa. I-placenta uhlobo lwento exhuma phakathi komama nengane. Ngalesi sici esibalulekile umntwana uthola oksijeni nezakhi. Ingane ithola ama-antibodies, kanye nama-hormone aphethwe ukuphepha kokukhulelwa nokuthuthukiswa okujwayelekile kwengane engakazalwa.

Ukwakhiwa kwe-placenta kuqala ngesonto emva kokukhulelwa, futhi ngemva kokubeletha isikhathi esingangxenye yehora ushiya isisu, enze yonke imisebenzi yakhe.

Abesifazane abaningi abakhulelwe banesithakazelo kumbuzo wendawo efanele yalesi sitho. Ngokuvamile, i- placenta itholakala eceleni kwodonga olungaphambili noma ngemuva, ngemuva kwesibindi. Leli lungiselelo liqinisekisa ukuphepha kwalo mzimba nokusebenza komsebenzi wayo odingekayo.

Indawo ye-placenta ixhomeke lapho iqanda elikhulelwe lizohlanganiswa khona emva kokukhulelwa. Ungathola i-placentation nge-ultrasound.

Isikhundla se-placenta esibelethweni singaba kanje:

- i-placenta eduze nodonga olungaphambili;

- i-placenta emdongeni ongemuva;

- i-placenta esifundeni se-uterine fundus;

- I-placenta endaweni yangasodongeni.

Zonke izinto ezibalwe ngenhla zijwayelekile futhi azifaki nengozi kokubili umama nomntwana.

I-placenta eduze nodonga lwangaphakathi lingasongela kuphela uma kwenzeka ukulethwa kwezidingo (isigaba sokudla). Lokhu kubangelwa ingozi eyengeziwe yokwelapha okungenzeka. I-placenta eduze nodonga lwangaphakathi lwesibeletho lungatholakala ngqo endaweni lapho udokotela adinga khona ukusika ukuze akhiphe umntwana.

Uma unesigaba se-cearean, futhi une-placenta yangaphakathi, akufanele ukhathazeke kusengaphambili. Odokotela abahlinzayo bayothatha zonke izinyathelo ezidingekayo zokunciphisa ingozi, futhi uma kwenzeka bephuma igazi, bazokwazi ukumisa ngokushesha.

Kwezinye izimo, okunamathiselwe okungavamile (okungavamile) kwe-placenta kungenzeka.

Isikhundla esiphansi se-placenta yisifo lapho isilwane esihlangene phakathi komama nesisu esitholakala ezingeni lamamitha ayisithupha noma ngaphansi ukusuka emphinjeni wangaphakathi entanyeni. Akunandaba ukuthi i-placenta ikuphi: eduze nodonga olungaphambili, eceleni kolunye uhlangothi noma ngemuva. Ibanga lomlomo wesibeletho lidlala indima. Ezimweni eziningi, indawo ephansi ye-placenta ayinaso isongo, ngoba ukukhula kwesisu kuqhubekela phezulu esibelethweni.

I-Placenta previa yilungiselelo lapho i-pharynx yangaphakathi ifaka khona (ingxenye noma ngokuphelele). Izinhlobo ezintathu zethulo zihlukaniswa: okusemkhawulweni, okwenziwe kamuva futhi okuphelele.

Esikhathini sesethulo esincane, i-placenta ihlanganisa ubuso obuphakathi komlomo wesibeletho ngokungabi ngaphezu kweyodwa yesithathu, nesethulo se-lateral - yizingxenye ezimbili kwezintathu, futhi ngokugcwele - ngokuphelele. Akunandaba ukuthi i-placenta itholakala edongeni langaphambili lesikhumba, kulandela i-lateral noma i-posterior.

Phakathi kwezinkinga ezitholakalayo ezinokutholwa njengesethulo, ungabona okuyinkimbinkimbi kunazo zonke: ukungafinyeleli ngokwanele, okuholela ekubambezelekeni kokuthuthukiswa kokubeletha, ingozi yokuphuma, ikakhulukazi esikhathini samasonto angu-28-32, lapho umsebenzi wesibeletho ukwanda, usongo lokukhulelwa luphazanyiswa. Ngokuvamile lapho i-placenta previa, isikhundla se-fetal esibelethweni singavamile (siyaphambana, i-oblique).

Ngesethulo esiphelele sowesifazane osemsebenzini, isigaba sokuhlelwa okuhleliwe senziwa ngesikhathi samaviki angu-38 wokukhulelwa. Uma kukhona isethulo sangasese noma esilandelayo, owesifazane okhulelwe angakwazi ukubeletha yodwa, uma isinqumo esinjalo senziwa udokotela ngemva kokuhlolwa. Kulokhu, uma kuzalwa ngokuzimela, ukuvulwa kwesikhumba sokuqala kuboniswa, kanye nokulungele ukusebenza okuphelele uma kwenzeka izimo ezingalindelekile.

Uma i-placenta itholakala edongeni langaphambili lebeletho, i-lateral noma i-posterior, eduze kwesibindi, khona-ke lokhu kuyinto evamile. Owesifazane okhulelwe onjalo angakwazi ukuthwala futhi abelethe ingane eyedwa. Uma unesikhundla esiphansi se-placenta noma isethulo salo, udinga ukuqapha njalo nokuqondiswa odokotela oya khona, ozokwazi ukwenza isinqumo esanele endabeni yokulethwa.
