Isimo esihle kakhulu somntwana esibelethweni yisethulo sekhanda le-fetus. Kodwa kwenzeka ukuthi ngisho nalapho ikhanda lomntwana libhekene nengxenyeni yangaphakathi yomlomo wesibeletho futhi livela kuqala (khona-ke amahlombe, i-trunk nemilenze) ngesikhathi sokubeletha, akuzona zonke izibeletho ezidlula ngokushesha ngaphandle kobunzima. Yona kanye inqubo yokuthunjwa kanye nomphumela wayo kuxhomeke ebukhulu bomntwana, umsebenzi womsebenzi wezisebenzi, kanye nesimo se-fetus esibelethweni.
Inendima enkulu ithathwa ngendalo ohlangothini oluseceleni kwengane ebhekene nayo, lapho ingemuva kwalo, yiyiphi ingxenye yekhanda engaphezu kwentamo yesisu, ngabe intamo ingasebenzi noma cha.
Kuye ngalezi zici zendawo yendawo yokuzalwa, ukubeletha kuzoqhubeka ngezindlela ezahlukene.
Izinhlobonhlobo zelungiselelo le-fetus enesethulo sekhanda:
- Ingane ingabuyela kumgogodla noma odongeni lomama womama.
- Isikhundla se-fetus sisekunene-ngakwesokunxele noma ngakwesobunxele. Okusho ukuthi, ingane iphenduke kancane ngakwesokudla noma kwesobunxele.
- Isikhundla se-fetus yile longitudinal, oblique, eguquguqukayo.
Isethulo se-longitudinal ye-fetus siyinhle kakhulu, ngoba ukuzalwa kulokhu kungahle kwenzeke ngokwemvelo. Kungaba ubuso, ubuso, iparietal kanye ne-occipital. Kuncike ekutheni yiyiphi ingxenye yengane yengane yindawo ehamba phambili yokuthuthuka ngokusebenzisa umsele wokuzala.
Isethulo se-Flexible occipital ekukhuleni kwengqondo kubhekwa njengempumelelo enkulu kakhulu. Iphuzu eliholayo lokuthuthuka emgodini wezintambo i-fontanel encane. Uma ingane ivela ekukhanyeni nge-occipital version yesethulo sekhanda lesisu, ngesikhathi sokuzalwa, i-nape iphenduka kuqala, ibheke phambili. Iningi lazo zokubeletha zenzeka ngale ndlela.
Kodwa ngesethulo sekhanda le-fetus, kunezinketho zokufakela phambili kwekhanda, okungafani phakathi kwabo futhi kuthinte i-biomechanism yomsebenzi.
- Ngokwezinga lokunwetshwa kwekhanda - isethulo se-anterolateral (preterminal), amathuba okulimala kumama nengane ngesikhathi sokubeletha, njengoba i-wire font yokuthunjwa yi-fontanel enkulu. Ukutholakala kokubeletha okuzimele akufakiwe, kepha ngokusho kwezibalo, kuvame ukusetshenziselwa isigaba sokugcina nokuvimbela i-hypoxia ye-fetal.
- Ngesethulo esiphezulu sekhanda, ukungena esikhwameni esincane senhloko yengane kuyisici sosayizi ogcwele. Iphuzu elibhebhethekisiwe ngokusebenzisa umsele wokuzala - ebunzini, okuphansi kakhulu maqondana nezinye izingxenye zekhanda. Lokhu kuhlukahluka kwaziwa nangokuthi inhlawulo ephansi yekhanda futhi ayifaki ukubeletha kwemvelo.
- Isethulo sobuso (i-III degree of extension of the head) yindawo ye-fetus lapho iphuzu eliholayo lesikhumba liyisimo esinjalo sokuthi ngesikhathi sokuzalwa ikhanda livela kusukela emgodini wokuzalwa emuva kwekhanda. Owesifazane angakwazi ukubeletha ngokwemvelo, uma nje isikhumba sakhe sinesayizi okwanele, futhi isithelo sincane. Kodwa-ke, ngesethulo sokubukeka, ukukhethwa kwesigaba se-caesarean kuvame ukucatshangelwa.
Izimbangela zezikhundla ezehlukene ezingajwayelekile nezethulo ze-fetus:
- i-pelvis encane kumuntu okhulelwe;
- isakhiwo esingavamile sesibeletho;
- uterine uterine;
- i-placenta previa, i-polyhydramnios;
- udonga lwesisu lomzimba;
- ubufebe nezinye izinto.
Ukuxilongwa kwesethulo sekhanda lesisu
Ku-ultrasound yesibili ehleliwe, usuvele unqume
Kusukela eminyakeni engama-28 isazi sezifo zokwelapha isifo sokubeletha sigqiba ukuboniswa kwe-fetus, kodwa kuze kube amasonto angama-33-34, izingane zingashintsha isimo somzimba. Kulesi simo, uzokwaziswa ukuba wenze izivivinyo ezikhethekile ukuze ulungise isimo. Uma udokotela ephikelela esibhedlela, qiniseka ukuthi uyamlalela.
Khumbula ukuthi kungakhathaliseki ukuthi ingane ijika kanjani, uxhomeke ekuziphatheni kwakho nokuzola. Landela izincomo zodokotela, hamba okuningi, cabanga ngelanga lapho uqala ukuthatha ingane yakho ukulala.
