Ubomi bomntu omncinci ngaphambi kokuzalwa ngaphakathi kumama kunikezelwa, ngaphezu kwayo yonke, imithwalo yegazi ezininzi, intambo ye-umbilical, i-placenta. Ufumana ezininzi izondlo kunye neoksijini egazini likaMama. Ukutshintshisiswa kwezinto phakathi komama nomntwana kunikezela nje izitho ezibini ezibalulekileyo ze-fetus - i-placenta kunye ne- chorion .
I-Chorion, ebonakalayo ekuqaleni kokukhulelwa, ikhula ne-fetus, ibe yindla. Ekupheleni kwekota yokuqala, iguqulwa ibe yi-placenta, apho umntwana enamathele eludongeni lwesisu. Ingqwalasela eninzi ihlawulwa kwindawo yendawo yokutya.
Iyiphi indawo eyona ndawo ikhethiweyo?
Ukunyamekela kwesikhotho kungenziwa ngaphambili, ngasentla, okanye enye yeendonga zecala. Indawo yokuhlala kwidonga ephezulu eludongeni (ingaphantsi kwesibeletho) ikwajongwa njengesiqhelo.
Ukuba umntwana uhlanganiswe nodongeni oluphantsi lwesibindi, ngoko bathi i-chorion iphantsi ngapha kwodonga olungaphambili (2-3 cm ukusuka kwisibeleko ukuya kwisibeleko). Eli lungiselelo le-chorion ecaleni kwodonga oluphambili lufumaneka kwi-6% yabasetyhini abakhulelweyo. Indawo ebonakalisiwe yokulungiswa kwesikhotho akuyiyo yokugqibela, tk. Kwiimeko ezininzi, i-chorion igxotha ukusuka kwindawo ephantsi ukuya kwindawo ephakamileyo, enceda ukuphepha iingxaki ezinxulumene nokuhlala kwendawo ye-chorion kwingingqi ye-pharynx yangaphakathi.
Ziziphi iingozi ezidibaniswa neentetho eziphantsi kwepenteko okanye i-chorion?
Lo mncipheko ukwandisa umngcipheko wokuphuphuma kwesisu, kwaye unokubangela ukuphuma kwegazi elikhulu, kokubili ngexesha lokukhulelwa nangethuba lokubeleka. Kwakhona isalathiso kwinqanaba le-caesarean kunye nangokwenyuswa ngokupheleleyo kwesisu emva kokunikezelwa. Ukuzalwa okuqhelekileyo kunokwenzeka kuphela xa i-placenta ingekho ngaphezulu kwe-2 cm ukuya ekuphumeni.
Ukuqukumbela inqaku lethu, siya kubonisa ukuba ibhinqa akufanele liyike ngenxa yezinto ezikhethileyo zendawo yokuhlala, into ephambili kukunyamekela ngethuba lokuba kubekho ukunikezelwa okuphantsi kwimiqathango yokugqibela kunye nokuthobela isigunyaziso sogqirha.
