Kwiiveki ezingama-33, ukukhulelwa kwakho sele kusondele ngokukhawuleza kwisigqibo sayo esifanelekileyo. Ngokomzekelo, abantu abaninzi bayaqaphela ukuba inani lokutshitshiswa liye lincinci kakhulu. Oku akumangalisi, kuba umntwana ukhula rhoqo, kwaye umlinganiselo we- amniotic fluid uyancipha kancane, okukhokelela ekuhambeni okungaphantsi komntwana. Emva kokugqitywa kwe-ultrasound kwiiveki ezingama-32-33 zokukhulelwa nokujonga iziphumo ngokuqhelekileyo, unokwazi ukubona i-pathologies enokwenzeka kwaye uthathe amanyathelo afike ngexesha. Kufuneka kuqatshelwe ukuba ngeli xesha umntwana ususebenza ngokusemthethweni, ngoko ke ukuzalwa kwangaphambi kwexesha elide kungasongela ubomi bakhe.
Imeko yomntwana
I-ultrasound ye-fetus kwiiveki ezingama-33 sele ivele isinika umfanekiso opheleleyo wempilo yengane, ubukho naziphi na iintsholongwane okanye iimpazamo ekuphuhliseni. Ukuba ngaphambili kwakungenakwenzeka ukucacisa ngesondo, ukuhlolwa kwe-ultrasound ngeli xesha kuza kunika umphumo othembekileyo we-100%. Ngelo xesha, ukuba ugqirha ngenxa yezizathu ezithile akakwazanga ukucacisa ngesondo somntwana, ngoko ke kunokwenzeka ukuba ngabazali bexesha elizayo le nto iya kuhlala ingummangaliso kwaze kwaba sekuzalweni. Inyaniso kukuba kukho iindawo ezimbalwa zokunyuka komntwana, ngoko akunakwenzeka ukuba uya kukwazi ukugqithisa.
Ngokusekelwe kwidatha ye-ultrasound kwiiveki ezingama-33, umhla wokuziswa okuzayo uchanekileyo ngokuchanekileyo. Ukongezelela, ugqirha ugqiba isikhundla se-fetus kwisibeleko, ithuba lokulenga intambo yesigqibo kunye nokugqiba iindlela zokuhambisa.
Amanqaku e-Ultrasound kwii-33 zesonto
Ukunyusa ubunzima beli xesha lokukhulelwa li malunga ne-300 g ngeveki, kwaye umntwana sele sele efikelela kwi-2 kg. Isiqhelo sobunzima bomntwana kulo mhla ngu-1800 ukuya ku-2550. Phakathi kwezinye iziphumo ezinokufumaneka kwi-ultrasound:
- ubude bezityalo (umgangatho wesi-35-45 cm);
- ubungakanani biparietal (ngokuqhelekileyo 75-90 mm);
- ubungakanani bendawo-occipital (ubuninzi 101-113 mm);
- kwinqanaba lekhanda (umgangatho 275-325 mm);
- ubude bomlenze (oqhelekileyo 60-70 mm);
- shank ubude (ejwayelekile 52-65 mm);
- ubude beli gxala (eliqhelekileyo lama-50-65 mm);
- ubude be-forearm (ejwayelekile 45-55 mm);
- Isibilini sesisu (umgangatho wama-265-325 mm);
- ithambo lomzimba (umgangatho we-9-14 mm).
Kubalulekile ukuba uqaphele ukuba umzimba ngamnye unempawu ezizimeleyo, ngoko ke ukungaqhelekanga okungafanelekanga akufanele kuthumele umama olindeleyo. Ukongezelela, iziphumo zezifundo ze-ultrasound zithethi kwaye zinephutha elithile. Ukuphanda izikhombisi ze-ultrasound kufuneka kuphela ugqirha oya kulo kuphela-ochwephesha ofanelekileyo unelungelo lokudweba naziphi izigqibo kwaye enze izigqibo malunga nokulaliswa kwezibhedlele okanye ukuhanjiswa kwangethuba.
