Uphando lwe-ultrasound, oluya ku funeka lwenziwe ngowesifazane okhulelweyo kwixesha elipheleleyo lokuthathwa kwexesha, ngumthombo kuphela wenkcazelo engathembekiyo okanye engathembekiyo malunga nexesha lokukhulelwa, ukukhula kunye nophuhliso lwefestile, ubukho bentsholongwane okanye iimpazamo zalo, njalonjalo. Kungenxa yale njongo ukuba i-fetometry iqhutywe, oko kukuthi, ukusekwa kobungakanani bentloko yomzali, enomdla kumagqirhacologists kunye nabagqithisi banoma yikuphi ukubonisana kwabasetyhini. Esi sibonakaliso siyicatshangelwa ngokufanelekileyo ukuba yinto ebaluleke kakhulu, kwaye iyakunikwa nayiphi na inkqubo yesigxina. Nangona kunjalo, akusiwo onke amabhinqa aqonda ngokucacileyo ukuba le yi-BDP ye-fetus, kutheni le minatha iyadingeka, yiyiphi imigangatho ekhoyo kwaye njalo njalo.
Yintoni ubukhulu bebiparietal yomntwana?
Ezi nkcukacha zifunyenwe ngamaza okubonakalayo kwikhrinta ye-ultrasound, efana nenqanaba le-ventricle yesithathu yengqondo. I-BDP ngexesha lokukhulelwa libonisa umgama owona mkhulu kunye omkhulu kunawo onke phakathi kweendonga zamathambo zesithsaba sekhanda lomntwana. Oko kukuthi, ubonisa ubungakanani bentloko yomntwana kwaye, ngenxa yoko, kubonisa idibaniselwano yombuso kunye nesantya sokuphuhliswa kwenkqubo ye-nervous kunye nexesha lokubamba.
Ubungakanani biparietal okanye i-BPD kuyimfuneko ukuqinisekisa ukukhuseleka komntwana womntwana kunye nomama, inqumlezo yesalathiso sokuzalwa kunye nokukhethwa kohlobo oluphezulu kakhulu lokunikezelwa kunye namaqhinga abasebenzi bezonyango ngexesha lokususwa komthwalo. Ukuba i-ultrasound ye-fetus BDP ibonisa ukungalingani okukhulu phakathi kobunzima bekhanda kunye nomsele wokuzalwa womama, onokuthi kwenzeke ngenxa yezizathu ezahlukahlukeneyo, icandelo elithintelo lokucwangcisa limiselwe.
Iimiselo zeBDP ngeveki
Kukho izikhokelo ezibizwa ngeveki zeBDP, ezijoliswe ngokukodwa kwikota nganye yesigxina, esenza kube lula ukuxilongwa. Izifundo zingenziwa ngokuqala-kuqala, kodwa ulwazi oluchanekileyo malunga nokuthotyelwa kophuhliso lomntwana kunye nexesha lokuthoba lufumaneka kwinqanaba lesibini okanye lesithathu lokukhulelwa.
Ukuqonda ukuba yintoni ubungakanani bebiparietal yomntwana kunye nokuba luhambelana neziphumo zakho kunye nemimiselo eqhelekileyo, kuyafaneleka ukuba uzibonele ngetafile apho idatha yeBDP iqhutywa ngeveki nganye. Ezi tebhile sele zifakwe kwinkqubo yomshini we-ultrasound kwaye kusekelwe kwisigqibo sokuba isiphelo sikhutshwe. Umqhubi okanye ugqirha ngokuzikhethela ukhetha uhlobo olufunekayo lweedatha aze alubeke ngqo phambi kokuba ufunde ngokwayo. Ungethuki ngokukhawuleza ukuba iziphumo zokugqibela azilungele, zihlala ziguqukayo kwimida ethile. Ukugqatswa kokugqibela kukuba ingaba i-BDP yesiqhelo ihambelana nexesha lakho lokuthoba. Umzekelo, i-BPR ye-18 mm ilingana neyesonto le-11 ne-12 ye-pregnancy.
Iimpawu zendlela i-BDP ithetha ngayo kwi-ultrasound
Ukudibaniswa kweso sikhombiso njengoko ubukhulu be-occiputo-frontal nedatha ye-BPR ivumela ukugweba malunga naluphi izinga lokuphuhliswa komntwana kunye nokuba kuthatha ixesha elingakanani ukukhulelwa. Emva kwakho konke, kuvela kwixesha lokubanjwa kweso sifundo sokuba uvavanyo oluqhelekileyo lwezinga lokuphuhliswa komntwana liqala, nokuba lizele okanye cha. Ubungakanani beBDP iiveki kunika ugqirha ngolwazi oluyimfuneko ukukunceda ukuseka imeko kunye nobukhulu bobuchopho ngokusekelwe kumthamo wekratshi kwaye, ngoko ke, yonke inkqubo yesantya yomntwana.
Ubungqina boluphawu lubonisa ukuba idatha ebonisa ukukhula kwayo iyancipha njengoko umntwana ekhula. Ngoko, umzekelo, i-BDP kwiiveki ezili-12, kwaye ngokukodwa ukukhula kwayo, malunga ne-4 millimeters ngeveki. Ekupheleni kwexesha lokuthoma, isibonakaliso seBDP kwiiveki ezingama-33 sele sele siphezulu kwi-1.2 okanye 1.3 mm.
Ngaloo ndlela, ukuqonda okuchanekileyo kwindlela ubukhulu bentsholongwane yebiparietal kunye noko kuthetha ntoni kukunceda ngexesha kunye nokuvavanya ngokupheleleyo izinga lokukhula kunye nophuhliso lomntwana ekuzalweni kwesibeleko.
