I-placenta yenziwa kusukela ekuqaleni kokukhulelwa futhi ngamaviki angu-16 kakade iyisitho esisebenza ngokugcwele. Umsebenzi oyinhloko we-placenta ukulethwa kwe-oksijeni nezakhi kumntfwana owenzayo, futhi ususe nemikhiqizo ye-waste (slags kanye ne-toxins) emzimbeni wayo. Umsebenzi ovamile we-placenta uthinta indawo yokunamathiselwe kwawo. Ngakho-ke, indawo ekahle ye-placenta yingxenye yesithathu engaphezulu kwendonga engemva kokuzalwa kwesibeletho. Esihlokweni sethu, sizocabangela izici zenkambo yokukhulelwa, uma kukhona indawo ye-placenta emgqeni wangaphambili wesibeletho.
Indawo yangaphakathi ye-placenta eduze nodonga lwangaphakathi lwesisu
Ukuhlanganisa i-placenta emdongeni wangaphambili kuvamile kulabo besifazane abaye baqala ukukhulelwa. Ngesikhathi sokukhulelwa, izintambo ze-muscle zodonga olukhulu lwangaphakathi lwe-uterus luyoluleka, futhi lokhu kuchaza izingozi ezingenzeka ngaleli lungiselelo le-placenta. Ukwelula ngokukhethekile ingxenye engezansi yesibeletho, ngakho-ke uma i-placenta itholakala phezulu odongeni olungaphambili lwesisu, lokhu akubanga ukwesaba okukhulu. Uma i-placenta itholakala edongeni langaphambili lesisu, umama ozayo angase azizwe kamuva kunendawo ehamba phambili ye-placenta, futhi izoba buthakathaka kakhulu. Indawo ngqo ye-placenta ingasungulwa kuphela ngesikhathi sokuhlolwa kwe-ultrasound ye-fetus .
Yiziphi izingozi ezingenzeka uma i-placenta itholakala edongeni langaphambili lesisu?
Uma i-placenta ifakwe odongeni lwangaphakathi lwesisu, ingozi yezinkinga ezilandelayo zanda:
- Ukunamathiswa okusondelene kwe-placenta . Ingozi yokunamathiselwa kwe-placenta enesibindi isanda kakhulu uma owesifazane ekhulelwa isisu nokukhulelwa, izifo ezivuthayo zezifo ze-endometrial, kanye nesigaba sokudla. Amathuba okuthandana kakhulu aphezulu ngaphansi kwezimo ezilandelayo: indawo ye-placenta iphansi eduze nodonga lwangaphakathi lwesibindi kanye nobunzima obungakhiwe ngemuva kokusebenza yi-section laarean. Uma kwenzeka i-placenta esondelene kakhulu, udokotela wenza ukukhishwa kwamandla kwe-placenta ngaphansi kwe-anesthesia jikelele;
- I-Placenta previa esodongeni langaphambili . Uma i-placenta ifakwe phansi ngapha kwodonga olungaphambili, ukwehlukaniswa kwalesi sigaba sesibeletho kuzophazamiseka. Ngakho-ke, i-placenta ekhulayo iyokwehla ku-pharynx yangaphakathi yesibeletho. Uma ibanga ukusuka emphinjeni wangaphakathi kuze kube semkhawulweni we-placenta lingaphansi kuka-4 cm, bese kuthiwa isethulo. Abesifazane abathintekayo nge-placenta previa odongeni lwangaphakathi kufanele bahanjiswe ngesigaba sokugcina;
- Inqola yangaphambi kwesigcawu se-placenta esivamile . Lokhu kunenkinga ngenxa yokuthi udonga lwangaphakathi lwesibeletho luncane futhi lunwetshiwe kangcono. Uma i-placenta itholakala edongeni langaphambili, lapho owesifazane eqala ukuzwa ingane, isisu singenza isivumelwano. Phakathi nokulwa okunjalo, ukuphazamiseka kwe-placenta kungase kwenzeke. Ukuphazamiseka kwamapulazi
kungenzeka ngosuku oluzayo ngenxa yokunyakaza okusebenzayo kwe-fetus. Lokhu kuyinkimbinkimbi eqondile yokukhulelwa, okungaholela ekulahlekelweni okukhulu kwegazi. Uma kutholakala usizo olungapheli, ukuphazamiseka okuphazamisayo kungaphelisa ukubulala komama nomntwana. Ngakho-ke, uma owesifazane ethola indawo yokuthola igciwane, kufanele ngokushesha aye esibhedlela.
Ngakho-ke, sihlolisise okukhetheni kwenkambo yokukhulelwa nokubeletha uma kwenzeka endaweni ye-placenta edongeni lwangaphakathi lombelethi, futhi futhi ucabangela izingozi ezingenzeka. Ngifuna ukugcizelela ukuthi isimo esibalulekile sokuvimbela izinkinga ezikhona kungenzeka ukuthi kuhambisane nesikhathi esifanele se-ultrasound nezinye izifundo eziphakanyisiwe.
