Ewe, asikwazi ukufumana izigqibo ezicacileyo, sithembele kuphela kule parameters, njengoko umntwana ngamnye eneshedyuli yakhe, kuxhomekeka kwizinto ezininzi. Nangona kunjalo, umntu akufanele akhoxise ezo zibonisi ezibalulekileyo. Ngokomzekelo, ngokobunzima bomntwana unokugweba ubomi bomntwana obusweni, ubukho bentsholongwane, ukungenakwanela kokutya kwezondlo okanye usongelo lokupheliswa kokukhulelwa.
Kuyafaneleka ukuba uqaphele ukuba ukulandelela indlela ukukhula kunye nobukhulu bomntwana obushushu buhluka kwiiveki zokukhulelwa, ungasebenzisa i- ultrasound. Le ndlela ikuvumela ukuba ufumane imilinganiselo echanekileyo yengane. Qiniseka ukuba umntwana uyakhula kwaye ukhula ngokuhambelana neshedyuli kunokuba kuviwo oluqhelekileyo, emva kokuba umjobi wezilwanyana alinganise ukujikeleza kwesisu kunye nokuphakama kokuma kwezantsi kwesibindi. Emva koko, ezi zixabiso ziyahluka ngokulingana nokukhula komntwana kwiiveki zokukhulelwa. Ngoko, ngaphambi kokuba ukhulelwe, umbele wesifazane ophilileyo oneminyaka engama-50 ukuya kwimizuzu engama-60, ngelixa ekupheleni kwexesha eli lixabiso liphuma kwi-1000-1300 amagremu. Okuyinto engokwemvelo, enikezelwa ukuba lo mzimba malunga neenyanga ezilisithoba kufuneka unikezele ngeemeko ezinobomi obukhululekile. Ngoko ke, njengoko umntwana ekhula, ubukhulu bombele bukhula ngeveki yokukhulelwa.
Ukuphindaphinda kokukhula komntwana emva kweiveki
Kukho itafile ekhethekileyo, ebonisa ukuba izinga lokukhula lokulinganisa nokulingana kwe-fetus ngeveki. Kakade ke, ixabiso langempela lingahluka kwizinto ezibonisiweyo, ekubeni ezi zinto zichaphazelekayo kwizinto ezahlukahlukeneyo, kuquka ukuzalwa. Nangona kunjalo, ekwenzeni umfanekiso oqhelekileyo wezinto ezenzekayo, i-correspondence yokukhula kunye nesisindo esiqhelekileyo, kwakunye nokunyuka kohlumo lwabo, badlale indima ebalulekileyo. Njengomthetho, ukulinganisa ukukhula komntwana kuqala kuphela ukusuka phakathi kwekota yokuqala, kuba ekugqibeleni ubude bokuba ububanzi bombungu basancinane.
Kulo mbono, kucetyiswa ukwenza i-ultrasound phambi kweveki ye-8.
Kule nqanaba, ukukhula komntwana kufaka umgama ukusuka kwisithsaba ukuya kumsila. Ngako oko, lo bukhulu bubizwa ngokuba yi-coccygeal parietal kwaye lukhethwe nje nge- KTP. I-KTP ilinganiselwa kwiiveki ezi-14 ukuya kwe-20 (kuxhomekeke kwisimo somntwana kunye nezakhono zengcali ewenza i-ultrasound) kuba ngaphambi kwalo mzuzu imilenze ye-crumb iyomelele kakhulu kwaye akunakwenzeka ukucacisa ubude obude.
Ukususela kwiiveki ezi-14 ukuya ku-20 zokukhulelwa, oogqirha bazama ukulinganisa umgama ukusuka ezintendeni ukuya kwisithsaba.
Ukukhula kwama-Fetal kwiiveki
Abasetyhini abaninzi baya kukhwela ukwenza i-ultrasound ngokukhawuleza emva kokulibaziseka. Kule meko, i-ultrasound inokuqinisekisa kuphela ubukho beqanda lomntwana kwiqanda le-uterine kwaye libeke ububanzi balo. Njengomthetho, kwi-iveki ye-6-7 yeveki yokukhulelwa, eli xabiso li-2-4 mm, kwaye nge-10 ukuya kwe-22 mm. Nangona kunjalo, indoda ezayo ikhula ngamandla kwaye ikhula, ngoko:
- ekupheleni kweeveki ezili-12, i-CTE yomntwana u-6-7 cm;
- Kwiiveki ezine ezizayo umntwana uya kukhula u-5 cm;
- kwaye kwiiveki ezingama-20 ubude ukusuka kwisithsaba ukuya kwisithende sifinyelela kuma-26 cm;
- kwiiveki ezingama-24 - 30 cm, kunye no-28-35 cm;
- kwiiveki ezingama-32, i-crumb iyakwenza ukuxhuma ekukhuleni ngo-7 cm;
- Kwiiveki ezingama-36 abaninzi abantwana bekulungele ukuba bazalwe, izitho zabo kunye neenkqubo zenziwa, ziye zafumana kwaye zakhula. Ngokukodwa, ngeli xesha ukukhula komntwana kungama-45-48 cm;
- nangona kunjalo, iiveki ezine ezisele ngaphambi kwendibano ethandekayo, i-crumb ayilahlekanga ize. Ngeli xesha, iintsana zingongeza i-100-300 gram ngeveki kwaye zikhule 1-2 cm;
- Ukukhula kwentsana ezalwe ngokutsha kwintsholongwane kuhluka kwi-48-54 cm.
