I-KTP ibalwa njani?
Njengolawulo, le parameter isetyenziswe ngexesha elifanayo, xa i-ultrasound ecwangcisiweyo ye-fetus isenziwa. Ukubala i-CTE, i-uterine cavity ichongiwe kwiiplanethi ezahlukeneyo ukuvavanya umntwana ovela kumacala onke, kwaye ukhethe i-index enkulu kakhulu ubude bomzimba wayo omncinci.
Iphi na i-KTP ilinganiswe nini na nini?
Ukulinganiswa kobukhulu be-cocgegeal-parietal yomntwana kuqhutyelwa ngamaxesha athile. Ixabiso le-CTE lomntwana lifaniswa netafile, ebonisa ukuqhelekileyo kwiiveki ezithile zokukhulelwa. Oku kukuvumela ukuba uphendule ngexesha lokutshintshwa kwenkqubo yophuhliso lokubeletha kwaye uhlolisise i-disorder ekuqaleni kwexesha.
Njengoko uyazi, ixesha le-ultrasound eliphambili liqheleke kwiiveki 10-12. Ukongeza, ngaphezu kokuvavanya imeko yesimo senhliziyo, ubuchopho, ukuchonga ngesondo lomntwana, isilinganiselo seKTR senziwa.
Esi sibonakaliso, njengomthetho, sikwazisa kuphela kwiiveki ezili-14. Ngoko ke, kwangaphambili isilinganiselo seKTR senziwa, ngcono. Ukuphunyezwa kokugqibela kule nkqubo kungenziwa ngaphandle kweveki ezili-15. Into kukuba ngeli xesha ezinye izikhombisi zentuthuko ye-intrauterine zifike phambili. Yingakho kwitafile ye-KTR iimpawu zendalo zibhalwa kuphela kwiiveki ezi-13 kuphela.
Ziphumelele njani iziphumo?
Njengoko sele kukhankanywe ngasentla, umgangatho weCTE we-fetus uhluka ngeeveki. Ngoko ke ugqirha kufuneka ahlole iziphumo.
Ngoko, kwixesha elidlulileyo leminyaka yeeveki ezi-6, i-CTE iqheleke kwi-7-9 mm. Nangona kunjalo, ngeveki ezayo, ngeveki 7, ngu-10-15 mm. Ngeveki ye-10, imbungu iyafikelela kubukhulu be-31-39 mm, kwaye ngo-12-13 ifikelela kuma-60-80 mm.
Itafile ye-KTR ibonisa ngokucacileyo ukuba eli pharamitha linyuka li-1 mm yonke imihla de iiveki ezili-12 zokukhulelwa. Kodwa ukusuka kweveki ye-13 yokuphuhliswa kwe-intrauterine, umntwana uqala ukukhula ngokukhawuleza, wongezelela u-2-2.5 mm ngosuku.
Kutheni i-KTR ilinganiswa?
Ngethuba le-1 trimester yokukhulelwa, umntwana ulinganiswa kwisibeleko ukusuka kwi-coccyx ukuya kwisithsaba. Oku kuchazwa yinto yokuba kunzima ukulinganisa isiqhamo ngenye indlela. ubukhulu bemilenze yabo buncinci kwaye isikhundla se-embryo sikuvimbela ukuba senze njalo.
Njengoko umntwana usalula, ulinganiswa ukusuka phezulu ukuya kwisithende. Ngelo xesha, kunzima ukukwenza ngokukhawuleza. Ngoko ke, yenza udibaniso lobungakanani beendawo ezithile ze-trunk, eyokuseka ukukhula komntwana. Kule meko, umntwana uqala ukulinganiswa ukusuka kwisithsaba ukuya emthonjeni, ngoko ubude bethanga ngokwalo, kwaye u-shank ulinganiswa. Nangona kunjalo, ngokugqithiseleyo, ugqirha akazifaki ezi zithethe, ukuthelekisa iimilinganiselo zabo kunye namazinga omntu ngamnye.
Ngaloo ndlela, wonke umama ozayo uza kufuneka azi ukuba yi-CTE yomntwana ebhekiselelweyo kunye nokuba kubalwa ntoni. Nangona kunjalo, akufanele udibanise ngokuzimeleyo iziphumo zemilinganiselo ngamanani athile, kwaye udwebe naziphi na izigqibo. Yonke le yimbopheleleko yoogqirha abahlalutya iziphumo, bengacingi ngokubaluleka kwamanani, kodwa nokukhulelwa, ixesha, ukukhulelwa okungafaniyo, okanye ukukhula komama noyise, njl njl. Ukuqwalasela kuphela zonke iimpawu ezikhankanywe ngasentla, umntu unokufikelela kwisigqibo ngokuphathelele imeko yomntwana kunye nokuhlaziya uphuhliso lwalo mntwana, emva kokumisa ukuphambuka kwimiqathango ekhoyo, ukuba kukho na.
