Ukuhlolwa kwe-1 trimester - ukuchazwa kwemiphumela

Ukuboniswa kwe-trimester kubonisani? Lokhu kuhlolwa kwe-ultrasound, okusiza ukunquma ukuthi kungenzeka yini khona izifo ze-chromosomal ekuqaleni kwezigaba zokukhulelwa. Phakathi nalesi sikhathi, abesifazane kufanele baphinde bahlolwe igazi nge- hCG ne-RAPP-A. Uma kubonakala ukuthi imiphumela yokuhlola i-trimester yokuqala ingalungile (isibalo se-ultrasound kanye negazi), lokhu kubonisa ingozi ephezulu ye-Down's syndrome ebusweni.

Izindlela zokuhlola i-trimester yokuqala nencazelo yazo

Ngesikhathi se-ultrasound, ukuqina komkhuhlane wesibeletho ku-fetus kuhlolwe, okumele kwandiswe ngokulingana njengoba kukhula. Ukuhlolwa kwenziwa ngeviki le-11-12 lokukhulelwa, futhi umkhuhlane wesibeletho kufanele ube yi-1 kuya ku-2 mm ngalesi sikhathi. Ngeviki 13, kufanele kufinyelele ubukhulu buka 2-2.8 mm.

Okwesibili kwezinkomba zesimiso sokuhlola i-trimester yokuqala yindlela yokubukeka kwethambo lomzimba. Uma ingabonakali phakathi nokuhlolwa, lokhu kubonisa ingozi ye-Down syndrome ku-60-80%, kodwa kubhekwa ukuthi kumaphesenti angu-2 wezingubo eziphilile, ngeke futhi kubonakale ngalesi sikhathi. Ngamaviki ayishumi nambili kuya kwesishiyagalolunye kuya kwesishiyagalolunye isisindo sobukhulu besithambo samasongo singama-3 mm.

Esikhathini se-ultrasound emavikini angu-12 anqume ukuthi ubudala nobusuku obuseduze bokuzalwa kwengane.

Ukuhlolwa kwe-trimester yokuqala - ukumisa imiphumela yokuhlolwa kwegazi

Ukuhlaziywa kwegazi nge-beta-hCG ne-RAPP-A kunqunywa ngokudlulisela ama-indices ibe yi-MOM ekhethekile. Idatha etholakalayo ibonisa ukuthi kukhona okungajwayelekile noma ukungabi khona kwabo ngesikhathi sokukhulelwa. Kodwa lezi zici zingathinta izici ezihlukene: ubudala nobukhulu bomama, indlela yokuphila nemikhuba emibi. Ngakho-ke, ukuze uthole umphumela onembile, yonke idatha ingena ohlelweni olukhethekile lwekhompiyutha, kucabangela izici zomuntu siqu zomama ozayo. Imiphumela yengozi yengozi lolu hlelo lubonisa isilinganiso 1:25, 1: 100, 1: 2000, njll. Uma uthatha, isibonelo, ukhetho 1:25, lo mphumela ukhombisa ukuthi ukukhulelwa okungama-25 nezinkomba ezifana neyakho, izingane ezingu-24 zizalwa ziphilile, kodwa zodwa kuphela i-Down syndrome.

Ngemuva kokuhlolwa kokuhlolwa kwegazi ku-trimester yokuqala futhi ngesisekelo sayo yonke idatha yokugcina etholakala, i-laboratory inganikeza iziphetho ezimbili:

1. Isivivinyo esihle.
2. Isivivinyo esibi.

Esikhathini sokuqala, kuzodingeka uhlole ukuhlolwa okujulile nokuhlolwa okwengeziwe . Ngenketho yesibili, izifundo ezengeziwe azidingeki, futhi ungalindela ngokuphepha ukubukwa okulandelayo okuhleliwe okwenzeka ngesikhathi sokukhulelwa phakathi no-2 trimester.
