Ngemuva kwenqubo ngayinye ye-ultrasound, abesifazane abakhulelwe bathola isenzo sokufunda ezandleni zabo, equkethe ulwazi olubalulekile ekuthuthukiseni umntwana. Omunye wemingcele ebaluleke kakhulu ye-fetus yayizibukhulu biparietal yekhanda, noma i-BPR. Iyini i-BDP ye-fetus nokuthi yikuphi okudingekayo, ukuthi i-BDP nokukhulelwa kuxhumene kanjani, yiziphi izinqubo zesikhumba senhloko biparietal amasonto - uzofunda konke lokhu kusihloko sethu.
БПР - ukucacisa
Phakathi ne-ultrasound, ukunakwa okukhethekile kubhalwa ekutadisheni ikhanda lomntwana. Lokhu akumangalisi: ubuchopho yingxenye ebaluleke kakhulu, ukukhula nokuthuthukiswa okuthinta ngqo ingane. Ukunquma ubukhulu bekhanda, ngakho-ke izinga lokuthuthukiswa kobuchopho lizosiza iBDP. Ubukhulu be-biparietal luhlobo "lobubanzi" bekhanda, olulinganiswa ne-axis encane, kusukela ethempelini kuya ethempelini.
Ngaphezu kwe-BPR, ubukhulu be-frontal-occipital (LZR) buchazwe - eduze kwe-axis enkulu, kusukela ebunzini kuya emasimini. Kodwa-ke, i-parameter esemqoka isala usayizi we-biparietal: isetshenziselwa ukunquma ubude bokukhulelwa. Ngokunemba okukhethekile, lokhu kungasungulwa ngesikhathi samasonto angu-12-28.
Amagugu e-BDP nawo abalulekile ekunqumeni ukuthi kungenzeka ukulethwa kwempilo. Uma ubukhulu bekhanda le-fetal alihambisani nobukhulu be-canal yokuzalwa, isinqumo senziwe mayelana nesigaba sokulondoloza esilungiselelwe.
Usayizi we-biparietal wekhanda - evamile
Ukuze kuhlolwe i-fetus ye-BDP isonto, amatafula akhethekile asetshenziswe, okukhombisa amanani ambalwa wekhwalithi ye-biparietal yenhloko ye-fetal kanye nokushintsha kwayo okuvumelekile. Ematafuleni e-BDP, amanani wekhanda lomntwana wesisu afakwe njengama-percentiles. Lena yindlela ekhethekile yokumelela izibalo zezokwelapha, okuyinto, njengomthetho, ebonisa inani elilinganiselwe (50th percentile), kanye nephansi (5th percentile) kanye nemingcele engaphezulu (95th percentile) yamagugu avamile.
Ukuze usebenzise le tafula futhi unqume umkhuba we-BDP we-fetus wamasonto, kubalulekile ukuthola inani lama-percentile angu-50, amanani asele anquma imingcele yezibonakaliso ezivamile. Isibonelo, emasontweni angu-12 umkhuba weBDP ungama-21 mm, nokubekezela okungama 18-24 mm. Lokhu kusho ukuthi uma inani le-BPR elingama-19 mm kumama ozayo akufanele likhathazeke mayelana nalokhu-cishe lokhu kuyisici sokuthuthukiswa kwengane.
I-BDP fetus etafuleni - ukuphambuka kusuka kwendabuko
Kwenzeka ukuthi izinkomba zeBDP zihamba ngaphezu kwemingcele evumelekile. Kusho ukuthini lokhu? Okokuqala, ukuze uqiniseke ukuthi ukungabi khona kwemithi kungabikho, udokotela kufanele ahlole ezinye izilinganiso ze-fetus (ubude bethanga, isisu somzimba). Uma zonke zidlulela isimiso esisodwa noma amasonto ambalwa, khona-ke singaxoxa ngesithelo esikhulu. Uma ezinye izilinganiso ze-fetometry zivamile, kungenzeka ukuthi ingane ikhula nge-jumpwise, futhi ngemva kwamasonto ambalwa wonke amamitha amamitha ahlukanisiwe.
Noma kunjalo, ukwehluka okuphawulekayo emagugu we-BDP kusukela kumkhuba kungabonisa izinkinga ezinkulu. Ngakho-ke, usayizi we-biparietal okhulayo ubonakala emathunjini amathangabi obuchopho noma ama-squake, kanye nase-hernia cerebral kanye ne- hydrocephalus . Kuzo zonke lezi zimo, ngaphandle kwe-hydrocephalus, owesifazane okhulelwe unikezwa ukuphazamisa ukukhulelwa, ngoba lezi zifo azihambisani nokuphila. Lapho kutholakala i-hydrocephalus, ama-antibiotic anikezwa futhi kuphela ezimweni ezingavamile (lapho kungekho khona umphumela wokwelashwa) ukukhipha isisu.
Ubukhulu obuncishisiwe obukhulu bekhanda le-fetal abukho kahle: njengomthetho, lokhu kusho ukuthuthukiswa kobuchopho noma ukungabikho kwezinye izakhiwo zayo (i-cerebellum noma i-hemispheres ye-cerebral). Kulokhu, noma nini ukukhulelwa kuphazamiseka.
Ku-trimester yesithathu, i-BDP encishisiwe ibonisa ukuba khona kwesifo se-intrauterine sokuphuza ukukhula. Ukwelashwa kwenziwa ngezidakamizwa ezithuthukisa ukugeleza kwegazi e-uterine-placental (kurantil, actovegin, njll).
