Xa ukhulelwe, amagama athi "vavanya" okanye "inkqubo" anokuvakala ngathi wothusa. Qiniseka ukuba awuwedwa. Kodwa ukufunda ngoba izinto ezithile ziyacetyiswa kwaye Njani zenziwe zingaluncedo ngokwenene.

Masikhuphe ukuba yintoni i-amniocentesis kwaye kutheni unokukhetha ukuba nayo.

Khumbula ukuba ugqirha wakho uliqabane kolu hambo, ngoko ke mxelele malunga nayiphi na inkxalabo kwaye ubuze imibuzo emininzi oyifunayo.

Yintoni i-amniocentesis?

I-Amniocentesis yinkqubo apho ugqirha wakho esusa inani elincinci le-amniotic fluid kwisibeleko sakho. Isixa samanzi esisusiweyo asihlali ngaphezulu kwe-1 ounce.

Amniotic fluid ijikeleze umntwana wakho esibelekweni. Olu lwelo luqulathe ezinye zeeseli zomntwana wakho kwaye lusetyenziselwa ukufumanisa ukuba ngaba umntwana wakho unayo nayiphi na into engaqhelekanga kwimfuza. Olu hlobo lwe-amniocentesis luhlala lwenziwa kwikota yesibini yesibini, ngesiqhelo emva kweveki ye-15.

Ingasetyenziselwa ukumisela ukuba imiphunga yomntwana wakho ikhule ngokwaneleyo ukuba ingaphila ngaphandle kwesibeleko. Olu hlobo lwe-amniocenteis luya kwenzeka kamva xa ukhulelwe.

Ugqirha wakho uya kusebenzisa inaliti ende, ebhityileyo ukuqokelela inani elincinci le-amniotic fluid. Olu lwelo lujikeleze kwaye lukhusele umntwana ngelixa besesibelekweni sakho.

Ingcali yelebhu iya kuthi emva koko ivavanye ulwelo kwiziphazamiso ezithile zofuzo, kubandakanya iDown syndrome, i-spina bifida, kunye ne-cystic fibrosis.

Iziphumo zovavanyo zinokukunceda uthathe izigqibo malunga nokukhulelwa kwakho. Kwi-trimester yesithathu, uvavanyo lunokukuxelela nokuba ingaba umntwana wakho ukhule ngokwaneleyo ukuba angazalwa.

Kwakhona kunceda ekunqumeni ukuba ngaba ufuna ukuhambisa kwangaphambili ukukhusela iingxaki ekukhulelweni kwakho.

Kutheni le nto kucetyiswa i-amniocentesis?

Iziphumo zovavanyo lokuvavanywa komntwana ngaphambi kokuzalwa sisizathu esivakalayo sokuthatha i-amniocentesis. I-Amniocentesis inokukunceda ugqirha wakho aqinisekise okanye aphike nakuphi na ukubonakaliswa kokungaqhelekanga okufumaneka ngexesha lovavanyo lokuhlola.

Ukuba sele unaye umntwana onesiphene sokuzalwa okanye ukungahambi kakuhle kwengqondo okanye intambo yomqolo ekuthiwa sisiphene se-neural tube, i-amniocentesis inokujonga ukuba umntwana wakho ongekazalwa unayo na imeko.

Ukuba uneminyaka engama-35 okanye ngaphezulu, umntwana wakho usemngciphekweni omkhulu wokuchaphazeleka kwe-chromosomal, njenge-Down syndrome. I-Amniocentesis inokuchonga oku kungaqhelekanga.

Ukuba wena okanye iqabane lakho ungumphathi owaziwayo wokuphazamiseka kwemfuza, njenge-cystic fibrosis, i-amniocentesis inokubona ukuba ngaba umntwana wakho ongekazalwa unale ngxaki.

Iingxaki ngexesha lokukhulelwa kunokufuna ukuba uhambise umntwana wakho ngaphambi kwexesha elipheleleyo. Ukuvuthwa kwe-amniocenteis kunokunceda ekuchongeni ukuba ngaba imiphunga yomntwana wakho ikhule ngokwaneleyo ukuvumela umntwana wakho ukuba aphile ngaphandle kwesibeleko.

Ugqirha wakho unokuphinda acebise i-amniocenteis ukuba bayakrokrela ukuba umntwana wakho ongekazalwa unosulelo okanye uneanemia okanye bacinga ukuba unosulelo lwesibeleko.

Ukuba kunyanzelekile, inkqubo inokwenziwa ukunciphisa isixa se-amniotic fluid kwisibeleko sakho.

I-amniocentesis yenziwa njani?

Olu vavanyo yinkqubo yezigulana ezingalaliswayo, ngoko akuyi kufuneka ukuba uhlale esibhedlele. Ugqirha wakho uya kuqala enze i-ultrasound ukumisela eyona ndawo umntwana wakho esibelekweni sakho.

I-ultrasound yinkqubo engavakaliyo esebenzisa amaza esandi aphakamileyo ukwenza umfanekiso wosana lwakho olungekazalwa. I-bladder yakho kufuneka igcwale ngexesha le-ultrasound, ke sela amanzi amaninzi ngaphambili.

Emva kwe-ultrasound, ugqirha wakho unokufaka isicelo sokunyanga amayeza kwindawo yesisu sakho. Iziphumo ze-ultrasound ziya kubanika indawo ekhuselekileyo yokufaka inaliti.

Emva koko, baya kufaka inaliti esiswini sakho nakwisibeleko sakho, bakhuphe inani elincinci le-amniotic fluid. Le nxalenye yenkqubo ihlala ithatha malunga nemizuzu emi-2.

Iziphumo zovavanyo lwemfuza kwi-amniotic fluid yakho zihlala zifumaneka kwiintsuku nje ezimbalwa.

Iziphumo zovavanyo lokuchonga ukukhula kwemiphunga yosana lwakho zihlala zifumaneka kwiiyure ezimbalwa.

Zeziphi iingxaki ezinxulumene ne-amniocenteis?

I-Amniocentesis ihlala icetyiswa phakathi kweeveki ezili-16 ukuya kwezi-20, okuphakathi kwekota yesibini yakho. Nangona iingxaki zinokubakho, kunqabile ukuba namava abanzima ngakumbi.

Umngcipheko wokukhulelwa kwesisu ufike kwiipesenti ezi-3 ukuba unenkqubo ngexesha lekota yesibini, ngokwe-Mayo Clinic. Umngcipheko uphezulu kancinci ukuba uvavanyo lwenzeka ngaphambi kweeveki ezili-15 zokukhulelwa.

Iingxaki ezinxulumene ne-amniocentesis zibandakanya oku kulandelayo:

• iicampu
• inani elincinci lokuphuma kwegazi kwilungu lobufazi
• i-amniotic fluid evuzayo ngaphandle komzimba (oku kunqabile)
• Usulelo lwesibeleko (nalo lunqabile)

I-Amniocentesis inokubangela usulelo, njenge-hepatitis C okanye i-HIV, ukuba igqithisele kusana olungekazalwa.

Kwiimeko ezinqabileyo, olu vavanyo lunokubangela ukuba ezinye iiseli zegazi lomntwana wakho zingene kwigazi lakho. Oku kubalulekile kuba kukho uhlobo lweprotheni ebizwa ngokuba yiRh factor. Ukuba unayo le protein, igazi lakho li-Rh-positive.

Ukuba awunayo le proteni, igazi lakho alinayo i-Rh-negative. Kuyenzeka ukuba wena nosana lwakho nibe nolwahlulo olwahlukileyo lweRh. Ukuba oku kunjalo kwaye igazi lakho lixubana negazi lomntwana wakho, umzimba wakho unokusabela ngokungathi uyaliwa negazi lomntwana wakho.

Ukuba oku kuyenzeka, ugqirha wakho uya kukunika iyeza elibizwa ngokuba yiRhoGAM. Eli yeza liya kuwuthintela umzimba wakho ekwenzeni ii-antibodies eziza kuhlasela iiseli zegazi zosana lwakho.

Zithetha ntoni iziphumo zovavanyo?

Ukuba iziphumo ze-amniocentesis ziqhelekile, umntwana wakho kunokwenzeka ukuba akanazo izinto ezingaqhelekanga zofuzo okanye i-chromosomal.

Kwimeko yokuvuthwa kwe-amniocenteis, iziphumo zovavanyo eziqhelekileyo ziya kukuqinisekisa ukuba umntwana wakho ukulungele ukuzalwa enamathuba aphezulu okusinda.

Iziphumo ezingaqhelekanga zinokuthetha ukuba kukho ingxaki yemfuza okanye ukungaqheleki chromosomal. Kodwa oko akuthethi ukuba kuphelele. Uvavanyo olongezelelweyo lokuqonda isifo lunokwenziwa ukufumana ulwazi ngakumbi.

Ukuba awucacanga malunga nokuba zithini na iziphumo, unganqikazi ukubuza umboneleli wakho wezempilo. Banokukunceda ekuqokeleleni ulwazi oludingayo ukuze uthathe isigqibo malunga namanyathelo alandelayo.
