Isikhundla esihle seplacenta sisondele kumgangatho wesibeleko, ngokuphindaphindiweyo eludongeni lwaso langaphambili, kwaye kaninzi kangako - ngasemva. Akusoloko i-placenta iyakunamathela kwaye iqale ukuphuhliswa ngokugcwele kule ndawo, ngoko le nxalenye ebalulekileyo yintsana iqhotyoshelwe kwicala eliphambene kufuphi nombele wesisu.
Ngokuxhomekeke kwindawo yokunamathisela, i-placenta iyahluka:
- ukunikezelwa ngokupheleleyo;
- intetho ephakathi;
- ntetho;
- intetho ephantsi.
Isalathiso sesigxina se-placenta sinqunywe ngelixa le-ultrasound elicwangcisiweyo yesibini, de kube ngeli xesha i-placenta isenokunyuka kwaye iphakame kwisimo esivamile ukusuka kwindawo engafanelekanga ngaphambili. Nangona kunjalo, ukuxilongwa kokugqibela kunokusondeza ekubelekeni. Le ntsholongwane ibhekiselwa kwintetho. Kwintetho yesigxina, uterine pharynx ivaliwe yimida yepentecenta malunga nesithathu.
I-placenta yesithili se-previa-izizathu
Iimbangela zengxelo esezantsi zingabonakali kwimpilo yowesifazane. Esona sizathu esiqhelekileyo sisifo sesifo sangasese, isisu, kunye neengxaki ekukhulelweni kokuqala. Ukongezelela, intetho ibonwa kwabasetyhini abaye bafumanisa ukuba bane-uterine fibroids okanye bane-pathology engamazalwa okukhubazeka kwe-uterine. I-Endometriosis inokubangela ukuncedisa okungavumelekanga kwipentecenta. Emva koko, kulo mzekelo iqanda le-fetal lelinamathele kuloo nxalenye yesibindi apho i-endometrium eyona ndawo iphilileyo. Indawo engafanelekanga ye-placenta idla ngokuphindaphindiweyo kubasetyhini abanokuzalwa abaninzi.
Yiyiphi into enobungozi engummiselo wepentecenta?
Ngomxholo osezantsi, umfazi angase aphephe. Kule meko, ukuphuma kwegazi kuqala ngokungalindelekanga, ngaphandle kwemizwa engathandekiyo neentlungu zomfazi okhulelweyo. Ngokuqhelekileyo, ixesha lokungcipheko liqala kwi-trimester yesithathu kwiiveki ezingama-28-32 zesigxina okanye ngexesha lobasebenzi.
Ngethuba elingafanelekanga le-placenta, kuquka i-krai, usongelo lokuphuphuma kwesisu luye lufunyanwe rhoqo. Kwakhona kungabonwa kwi-hypotension ekhulelwe-uxinzelelo lwegazi oluphantsi; kwaye uphuhliso lwe-anemia alukhangeli. Ukongezelela, ngesalathiso esincinci, umntwana angathatha isikhundla esingafanelekanga kwisigxina se-uterine, esiya kufuna ukungenelela.
I-placenta ye-previa yonyango
Njengomthetho, unyango oluthile lokunyangwa kwe-presentation engezantsi alusebenzi. Iingongoma eziphambili ziphumle ngokuzenzekelayo okanye ngokuzenzekelayo kunina. Oku akubandakanyi ukuphakamisa izisindo. Ukususela kwisondo kunye nomboniso omgca we-placenta, njengoluhlobo oluthile, kungcono ukunqanda.
Nangona kunjalo, kunye nesingeniso sesigxina, ukuhlolwa rhoqo kwezokwelapha kunye nokuxilongwa okufanelekileyo ngexesha elifanelekileyo. Iimpawu eziphambili ezimele zibekwe iliso kuhlolwa kwegazi ngenxa ye-hemoglobin kunye ne-coagulation. Emva koko, ukuba i-anemia ikhula, ibhinqa liya kufuna ukunika izidakamizwa ezinezinyithi. I-blood coagulation kufuneka ibe yinto evamile xa kuphuma igazi. Uxinzelelo lwegazi lusetyenziswa rhoqo. Kwaye, ke, i-ultrasound, ekwazi ukuchonga ngokuchanekileyo utshintsho kwindawo ye-placenta.
Ukuzalwa kunye neentetho zangaphandle
Isigqibo malunga nendlela ukuhanjiswa kwezifundo kuya kwenzeka ngayo kuya kwenziwa ngudokotela oya kwiindawo, kunye nogqirha othabatha ukuhambisa. Ngoko ke, kungcono ukuqhagamshelana newadi yokubeleka ngaphambi kokuqala komsebenzi.
Ukuzalwa kunye nokuboniswa komgca we-placenta kunokuthi kwenzeke ngokwemvelo, ukuba akukho zikhombisi zokuqhuba icandelo eliqhotyoshelweyo . Ngolu hlobo lokuxilongwa, ukuphuma kwamanzi, njengomthetho, akuyikukhuphela kwaye kuyeka ngokukhawuleza xa intloko yomntwana ibandakanya umlenze wesibindi. Nangona kunjalo, kukho ukuhlala kunokwenzeka ukugqitywa kwezabasebenzi ngendlela yokusebenza, emva koko, ngokuqhelekileyo kunokwenzeka ukubeka ngokucacileyo ukuba i-placenta ikhusele i-uterine cavity kuphela emva kokuvulwa komlomo wesibeleko ngo-5-6 cm.
Kwinqanaba leentsholongwane zonyango kunye neyeza, unomfazi ofunyaniswa ukuba enepentecenta previa ayinakukhathazeka ubomi bakhe nobomi bentsana yakhe.
