Emva kwenkqubo nganye ye-ultrasound, abafazi abakhulelweyo bayayifumana inkqubo yokufunda ezandleni zabo, equlethe inkcazelo ebalulekileyo ekuphuhliseni umntwana. Enye yeeparitha ezibalulekileyo ze-fetus yayizikhulu yebiparietal yentloko, okanye i-BPR. Yiyiphi i-BDP ye-fetus kunye noko kukufunekayo, indlela iBDP kunye nokukhulelwa kuhlobene ngayo, yintoni imimiselo yobunzima bentloko yeeveki kwiiveki - uya kufunda konke oku kwinqaku lethu.
БПР - ukucacisa
Ngexesha le-ultrasound, ingqalelo ekhethekileyo ihlawulwa ekufundweni kwentloko yomntwana. Oku akumangalisiyo: ingqondo yimbutho ebaluleke kakhulu, ukukhula kunye nophuhliso oluchaphazela ngqo umntwana. Misela ubungakanani bentloko, kwaye ngoko izinga lophuhliso lobuchopho luya kunceda iBDP. Ubungakanani beBiparietal luhlobo "lobubanzi" bekhanda, lilinganiselwe kwinqanaba elincinci, ukusuka ethempelini ukuya etempileni.
Ukongezelela kwi-BPR, ubukhulu be-occipital size (LZR) buchazwe kwakhona - kunye ne-axis enkulu, ukusuka ebunzini kuya kwimeko ye-occiput. Nangona kunjalo, iiparameter eziphambili zihlala zibukhulu biparietal: isetyenziselwa ukuchonga ixesha lokukhulelwa. Ngokuchanekileyo okuchanekileyo, oku kuya kusekwa ngexesha leiveki ezili-12 ukuya kwe-28.
Imilinganiselo yeBDP nayo ibalulekile ekuqaliseni ukuba kunokwenzeka ukunikezelwa kwempilo. Ukuba ubungakanani bentloko yentloko abuhambisani nemilinganiselo yesondo lokuzalwa, isigqibo senziwe malunga necandelo elicwangcisiweyo lokucima.
Ubungakanani biparietal yekhanda - ngumqhele
Ukuvavanya kwe-BDP fetus kwiveki, iitheyibhile ezizodwa ziye zaphuhliswa, ezibonisa iindleko eziqhelekileyo zobuninzi bebiparietal intloko ye-fetal kunye nokuguquka kwayo okuvumelekileyo. Kwiithebhile ze-BDP, ixabiso lentloko yesayizi yentloko limelelwe njenge-percentiles. Le yindlela ekhethekileyo yokumela amanani enzululwazi, apho, njengomthetho, ubonisa inani elilinganayo (50th percentile), kunye ne-lower (5th percentile) kunye nomda ophezulu (95th percentile) kwemida eqhelekileyo.
Ukuze usebenzise le tafile kwaye unqume umgangatho weBDP we-fetus kwiiveki, kubalulekile ukufumana ixabiso le-percentile yama-50, ixabiso eliseleyo limisela imida yezibonakaliso eziqhelekileyo. Umzekelo, kwiiveki ezili-12 umgangatho weBDP ungama-21 mm, kunye nokunyamezela kwe-18-24 mm. Oku kuthetha ukuba xa ixabiso le-BPR le-19 mm kumama ozayo akufanelekile ukukhathazeka malunga nalo-oku kunokwenzeka ukuba luphawu lophuhliso lomntwana.
I-fetus yeBDP etafileni - ukuphambuka kwimiqathango
Kwenzeka ukuba izibonakaliso zeBDP zihamba ngaphaya kwemiqathango evumelekileyo. Kuthetha ukuthini oku? Okokuqala, ukuze uqinisekiswe ukungabikho kwempilo, ugqirha kufuneka ahlole ezinye iiparamitha zesisu (ubude bethanga, isisu somzimba). Ukuba zonke zigqithise umgangatho omnye okanye iiveki ezimbalwa, ngoko unokuthetha ngesityalo esikhulu. Ukuba ezinye ixabiso le-fetometry liqhelekile, ngoko ke kunokwenzeka ukuba umntwana uyakhula ngokukhawuleza, kwaye emva kweveki ezimbalwa zonke iiparamitha zifakwe.
Nangona kunjalo, ukuphazamiseka okuphawulekayo kwixabiso leBDP ukusuka kwisiqhelo kungabonisa iingxaki ezinzulu. Ngaloo ndlela, ukwanda kwe-biparietal kubonakala kwimizimba yesifo sengqondo okanye yegazi, kunye ne-cerebral hernia kunye ne- hydrocephalus . Kuzo zonke iimeko, ngaphandle kwe-hydrocephalus, owesifazane okhulelwe unikwe ukuphazamisa ukukhulelwa, kuba le mizimba ingavumelani nobomi. Xa i-hydrocephalus ifunyenwe, i-antibiotics ilawulwa kwaye kuphela kwiimeko ezinqabileyo (ngokungabikho kwefuthe lonyango) ukukhupha isisu.
Ubungakanani obuncitshisiweyo bentloko ye-fetal nayo ayiyi kuhamba kakuhle: njengokulawula, oku kuthetha ukuphuhliswa kwengqondo okanye ukungabikho kwamanye amaziko ayo (i-cerebellum okanye i-hemispheres ye-cerebral). Kule meko, nangaliphi na ixesha ukukhulelwa kukuphazamiseka.
Kwi-trimester yesithathu, i-BDP eyancitshiweyo ibonisa ubukho be-syndrome ye-intrauterine yokulinda ukukhula. Unyango luyenziwa kunye neziyobisi eziphucula ukuphuma kwegazi e-placental (kurantil, actovegin, njl.).
