I-Amniocentesis ithatha ingozi encane yokukhulelwa kwesisu
I-amniocentesis uhlobo lokuhlolwa kokubeletha okubandakanya ukufaka inaliti ngesisu somama ukuqoqa isampula se-amniotic fluid bese uhlola i- amniotic fluid ukuhlola ama-chromosomes wengane. Kodwa-ke, i-amniocentesis ingaba yingxabano ngezizathu ezimbili: ukuhlolwa kubeka ingozi encane yokubangela ukukhulelwa kwesisu , futhi imiphumela yokuhlolwa ingabangela abantu ukuba bakhethe ukuqeda ukukhulelwa kwabo .
Ngakho-ke, abanye besifazane abakhulelwe bayesaba ukuhlolwa kanti abanye bayashintsha ukusetshenziswa kwayo.
Okuthi Siyazi Ngo-Amniocentesis
Ngenxa yokuthi banengozi eyengeziwe yokuba nengane ene-chromosome disorder, ama-moms angaphezu kuka-35 anganikezwa i-amniocentesis noma i- CVS njengesivivinyo somkhuba. Kodwa amanye amamama angeke ahlinzekwe nge-amniocentesis ngokuzenzakalelayo ngaphandle kokuthi abantwana babo bazimisele ukuba nengozi enkulu yezinkinga ze-chromosome. Isibonelo singaba uma ukuhlolwa kwegazi kathathu noma kwe-quad kwesikrini kubonise ukulinganisa okuphakeme kwesimo esithile.
Yini Yonke Ingxabano Ngama-Amniocentesis?
Ngakho uma i-amniocentesis ingumvivinyo wezinkinga ze- chromosome , kungani abantu bekhathazekile ngakho, omunye angase azibuze?
Mhlawumbe isizathu esikhulu kunazo zonke abantu abakhathazekile nge-amniocentesis yingozi encane eyengeziwe yokukhulelwa kwesisu - nokuthi iqiniso lokuthi izinombolo eziningi zisetshenziselwa ukulinganisa le ngozi. Ukucwaninga okuthembekile kubonisa ukuthi ingozi ye-amniocentesis eyenza ukukhulelwa kwesisu iyingxenye eyodwa kwezingu-400 kusetshenziswa izindlela zanamuhla, kodwa imithombo ethile isasebenzisa ukulinganisa okudala, okulinganiselwe kwe-1 ku-200 noma ngisho nengozi eyodwa kokungu-100 yokukhulelwa kwesisu.
Futhi ngokwemvelo, abanye abantu banomuzwa wokuthi noma iyiphi ingozi eyengeziwe - kungakhathaliseki ukuthi encane kangakanani - iphakeme kakhulu.
Esinye isizathu sokuthi kungani abantu bengase bahlasele i-amniocentesis kungenxa yokuthi abanye abazali banquma ukuqeda ukukhulelwa kwabo lapho bezwa ukuthi umntwana unenkinga ye-chromosome. Isifo esivame kakhulu abantu abacabanga ngaso lapho bekhuluma ngo-amniocentesis yi-Down syndrome, isimo esibangela ukukhubazeka kokuthuthukiswa nokuqonda.
Abanye abantu baziphatha ngokumelene nokuqedwa kwezinsana ezine-Down syndrome, ikakhulukazi ngoba isimo asivangeli izinkinga zempilo esongela impilo, ngakho-ke izigwebo zokuziphatha zabantu ekuqedeni zingase zifinyelele ekuvivinyweni kwe-amniocentesis ngoba ukuhlolwa kungabangela abantu banquma ukuqeda ukukhulelwa kwabo.
Izinzuzo ze-Amniocentesis
Izizathu zokuba ne-amniocentesis ziningi, kodwa enkulu kakhulu ukuthi ukuhlolwa kukunikeza impendulo enengqondo ngokucacile ukuthi ngabe ingane yakho inezifo ezingathí sina se-chromosome. Ngesilinganiso sokunemba esingu-99.4%, izinkinga ziphansi ukuthi i-amniocentesis yakho izokunika amanga noma amanga enkingeni ye-chromosome.
Kubazali abangakhetha ukuqeda ukukhulelwa ngezifo ze-chromosome, ukunemba kwe-amniocenteis kuyisimo esiqinile sokwenza ukuhlolwa.
Ngaphezu kwalokho, naphezu kokuhlangana okuvamile ne-Down syndrome ukuhlola, i-amniocentesis ingabuye iqinisekise noma ikwazi ukukhipha ukuphazamiseka okuncane ngokuhlukunyezwa okubi nakakhulu kune-Down syndrome. Kungenzeka ukuthi abazali abangazange bakhethe ukuqeda ingane ene-Down syndrome babezocabangela ukuqedwa uma i-amniocentesis yembula isimo esinamandla okubangela ukufa ekuntwaneni kwasekusaneni, njengo- Edwards syndrome noma i- triploidy . Ezimweni ezinjalo, i-amniocentesis ingaba yindlela enokwethenjelwa yokuhlukanisa ukuthi iyiphi i-chromosome disorder ingane eyenayo lapho kwenzeka ukuthi ukuhlolwa kokuhlola noma i- ultrasound kubangele imbangela enkulu yokukhathazeka mayelana nokukhathazeka kwe-chromosome.
Okokugcina, kungakhathaliseki ukuthi imizwa yabantu ekupheleni, i-amniocentesis ingasiza abazali nabahlengikazi ukuba bazilungiselele ukubhekana nezidingo zomntwana ngesikhathi sokuzalwa. Ngisho nabazali abangeke baqede ukukhulelwa bangakhetha ukuthi babe nolwazi olusengaphambili lokuxilongwa kwengane ukuze bakwazi ukucwaninga lesi simo futhi bazi ukuthi yini okufanele balindelwe ngesikhathi sokuzalwa.
Umthengi we-Amniocentesis
Ukungqubuzana okuyinhloko ngokumelene ne-amniocentesis kuyingozi encane eyengeziwe yokukhulelwa kwesisu. Kuningi lokubika okuphikisanayo ngezinombolo zangempela, kodwa ngisho nokulinganiswa okuvunyelwe kwe-1 ku-400 kungase kusabe kakhulu kwabanye abomama - ikakhulukazi labo abanomlando wokukhulelwa kwesisu noma ukungabi nabantwana.
Ngisho nabomama abathola imiphumela yesithathu yekhredithi ekhombisa ukuthi ukucindezeleka kwe-chromosome ephakeme kungakhetha ukulwa no-amniocentesis ngalesi sizathu.
Ngenxa yezinkolelo zenkolo noma zefilosofi, amanye amamazana angase abe nomuzwa wokuthi angeke acabange ukuqeda ukukhulelwa nganoma yisiphi isizathu - ngisho noma ingane isifo esibulalayo sokugula. Uma sekuphelelwe umbuzo, laba mama bangase banqume ukuthi akusizo inzuzo yokuba ne-amniocenteis ngoba izoba nengozi encane futhi ngeke ishintshe umphumela.
Lapho i-Amniocentesis iqala khona
Kungenzeka ukuthi ucwaningo lwesikhathi esizayo lungenza yonke ingxabano mayelana ne-amniocenteis ayifanele. Abacwaningi benza umsebenzi wokudala izivivinyo ezingenasisindo ezincane ukuze zibukeze izifo ze-chromosome ekukhuliseni abantwana, njengokuhlukanisa izinto zobunikazi ezivela kumasampula egazi lomama. Isikhathi sizokutshela lokho okuvela kulowo mzamo, kodwa okwamanje, i-amniocentesis yiyatholakala.
Ukusebenzisa izinombolo ezifanele engozini yokulahlekelwa amandla ngemuva kwe-amniocentesis, isiphetho esingokwemvelo singabonakala sengathi amama omngcipheko wokuba nengane ene-chromosome disorder ingaphansi kwe-1 ku-400 akufanele ibe ne-amniocentesis (ngoba izinkinga zokuhlolwa okwenza ukukhulelwa kwesisu kube ngaphezulu).
Amama omngcipheko wokuba nengane ene-chromosome disorder iphakeme kune-1 ku-400, kungakhathaliseki ukuthi yiminyaka yobudala noma kathathu / isikrini se-screen, kufanele babe nokukhetha kokuhlolwa. Njengemibuzo eminingi, omama kufanele basebenze nodokotela babo ukuze benze izinqumo ezifanele kakhulu izinkolelo zabo zefilosofi nezimo zezokwelapha.
