Kule nqaku, siza kuthetha malunga nohlobo luni lophando olubandakanya ukuhlolisisa i-trimester, zingaphi iiveki ezenziwe, kunye nento ugqirha eya kukwazi ukuyibona ngexesha lovavanyo.
Ziziphi iziphumo ezihlolwe i-3rd trimeter?
Ngokuqhelekileyo, ukuhlolwa kwesithathu kubandakanya ukuxilongwa kwe-ultrasound kunye ne- cardiotocography (CTG). Kwiimeko ezinqabileyo, ukuba kukho izikhalazo ezinzulu zokuphucula i-chromosomal ekuveliseni umntwana, loo mfazi uya kufuneka athathe uvavanyo lwegazi ukuchonga izinga le-hCG, i-RAPP-A, i-lactogen ye-placental kunye ne-alfa-fetoprotein.
Ngoncedo lokuxilongwa kwe-ultrasound, ugqirha uvavanya ngokupheleleyo zonke izitho kunye neenkqubo zexesha elizayo umntwana, kwakunye nesantya sokukhula kwe-placenta kunye nomthamo we-amniotic fluid. Ngokuqhelekileyo, xa uvavanyo lwesithathu lwe-ultrasound lwenziwe ngexesha lokukhulelwa, i- Doppler nayo yenziwa , evumela ugqirha ukuba ahlole ukuba umntwana unayo i-oksijeni eyaneleyo, kwaye ubone ukuba umntwana unesifo somzimba.
I-CTG yenziwa ngexesha elifanayo njenge-ultrasound, okanye kamva kamva ngenjongo yokugqiba ukuba umntwana uyaphathwa yi-hypoxia, kwaye intliziyo yakhe ibetha njani. Kwimeko ye-Doppler kunye ne-CTG iziphumo, ibhinqa elikhulelweyo lidlalwa ngokubhedlele esibhedlele kwisibhedlele sokubeletha, kunye neengxaki ezintle zezi zifundo, ukuzalwa kwangaphambi kokuzalwa kusakhulayo.
Iyiphi iveki yesithathu ephakanyisiweyo yokuhlola?
Ugqirha obona ukukhulelwa, kwimeko nganye, uqikelela xa kuyimfuneko ukwenza uvavanyo lwesithathu. Ngamanye amaxesha, ngokukrokreka ukuba umntwana esiswini asinalo ngokwaneleyo i-oksijeni kumama, umzekelo, ngenxa yokuguga ngobukhulu bomntwana, ugqirha unokumisela inkqubo ye-KTG okanye i-doppler kwiveki yama-28. Ixesha elifanelekileyo kuzo zonke iiphononongo ezihambelana nokuhlolwa kweyesithathu lixesha ukusuka kwiiveki ezingama-32 ukuya kuma-34.
Kungakhathaliseki ukuba ubude bokuba ngumfazi, ukuba ukuphambuka kufunyanwe ngexesha lokuphonononga kwe-3rd trimeter, kuyacetyiswa ukuba isifundo sesibini sifumaneke kwiiveki ezi-1-2 ukuphepha ukuba kwenzeke impazamo.
