Vakadzi vakawanda mushure me ultrasound vanotya kuguma kwechiremba kuti chirongwa chemubilical chine midziyo 2 panzvimbo yevatatu, sezvinotarisirwa. Vanachiremba havasi nguva dzose vanopa ruzivo rwakakwana, uye mamamamangwana mune ramangwana vari kunyanya kunetseka nezvemibvunzo - chii chingaita kumwana uye chii chingaitwa kudzivisa migumisiro. 2 midziyo mumutsara wembilical - iyi inowanzosvibisa, iyo mhedzisiro inogona kunge isina kusimba yemucheche, kazhinji mwoyo unotambura.
Ndeipi midziyo yakawanda inofanira kunge yakagadzirirwa?
Mutsara wembilical (umbilical cord) inhengo inobatanidza fetus nemuviri waamai, inosvika kureba 50-70 cm kana kupfuura. Mutsara unofanirwa kuva nemidziyo mitatu, iyo: mishonga mbiri uye imwe mutezo. Nemaaplasia (kufambiswa kusina kunaka) kwechimwe chidziro chetambo, unhu hunokonzerwa - tsvimbo yembilical 2 yemudziyo, i.e. imwe ariti uye imwe mutezo. Itiyeri inotakura ropa re fetal, yakazara ne carbon dioxide uye zvinhu zvinosvibisa zve metabolism kune amai amai. Imbilical vein inotakura ropa, iyo inowedzerwa neoksijeni nemuviri, zvichibva kumamarecenta kusvika kumwana. Pakuberekwa, midziyo 2 mumutsara wembilical inogona kukonzera fetal hypoxia, saka chikamu chechirea chinoratidzwa mumamiriro ezvinhu akadaro. Paanenge aberekwa, mwana anofanira kupiwa kunyatsoteerera, sezvo ropa richiyerera rinogona kushaya simba pakucheka musimboti wembilical.
Panguva yekuzvitakura zvakakosha kuonekwa seti genetics kuti isabvisa chromosomal zvisiri izvo (chiremba kazhinji anoratidza kuita cardocene - kuongorora ropa kunotorwa kubva mumutsara wembilical). Uyezve kusvika masvondo makumi maviri nemasere, unoda kuita ultrasound ye fetal heart (kuti udzivirire chirwere chemwoyo chinogona kuitika) uye inowedzera ultrasound yezvikamu zvose. Kuti vadzivise kuputsa, vanachiremba vanosarudza ma-weekly CTG uye doppler.
Kudzidzira kunoratidza kuti nhamba ye umbilical cord midziyo haigoni kuchinja hutano hwemwana. Uye kuberekwa kwomwana ane kupesana munyaya iyi kunowanzove kusinganzwisisiki: mune humwe hupenyu hwemwana, imwe arteri haina basa.
