Ubukhulu nokukala kokuvuthwa kwe-placenta yizinkomba ezimbili ezibaluleke kakhulu ngesikhathi sokukhulelwa, okungaqondiswa kuphela ukusebenzisa i-ultrasound. Kunezinhlobo ezithile zokukhula nokuqina kwe-placenta. Ukuphambuka kubo kusongela izinkinga eziningi ezingathandeki, ngisho nokudabukisayo kakhulu.
Ukwandisa ubukhulu be-placenta kubonisa ukutholakala kwempilo. Lokhu ngezinye izikhathi kwenzeka ngesikhathi sokudluliswa ngesikhathi sokukhulelwa kwesifo esiyingozi, kanye nesifo sikashukela, isifo sikashukela, i- gestosis ne-Rhesus impikiswano. Ngakho-ke, abesifazane abanezifo ezibhekwa ngokucophelela phakathi nokukhulelwa.
Kuye ngegama, ukuqina kwe-placenta kunamagugu ahlukene okujwayelekile. Ngendlela, ukuphambuka kwayo kuze kube sehlangothini encane kubhekwa njengengculazi. Uma ubukhulu be-placenta buyancipha, isimo sabizwa ngokuthi i-hypoplasia. Lesi simo sibangelwa izizathu ezifanayo njengokuqala kokuvuthwa kwe-placenta - ukubhema nokuphuza abesifazane abakhulelwe, izinqubo ezithathelwanayo njalonjalo.
Yini okufanele kube ukuqina kwe-placenta?
Emasontweni angu-21, ubukhulu be-placenta bufinyelela ezingeni lika-17.4 mm. Isonto ngalinye, lesi sibalo sanda cishe ngo-1 mm. Ubukhulu be-placenta emavikini angu-36 buyi-35.5 mm, emavikini angu-37 - 34.4 mm. Okusho ukuthi inani eliphakeme lokuqina liwela ngqo emavikini angu-36. Ngemva kwalokhu, i-placenta kancane kancane iba mncane. Ekupheleni kokukhulelwa, ubukhulu be-placenta akufanele kube ngaphezu kwama-34 mm.
Yiqiniso, zonke lezi zibalo zingahlukahluka ngezinga elithile. Kodwa ukuphambuka okuphawulekayo okuvela kumkhuba kufanele kuxwayise odokotela. Kulesi simo, kwenziwa i-ultrasound, i-doplerography ne-cardiotocography.
Ukukhula kwe-placenta
Lesi sibonakaliso sikhombisa ukuthi isakhi esibalulekile kangakanani njengoba i-placenta yenza imisebenzi yayo. I-zero degree igcinwa kuze kufike amasonto angu-27, kufinyelela ku-32 izinga lokuvuthwa libe yesibili, futhi ngeviki ezingu-37 - okwesithathu.
I-degree yesine yokuvuthwa kwe-placenta ihambelana nezimo zokukhulelwa. Ngakho-ke, akuwona wonke umuntu ohlola i-ultrasound le degree of ukuvuthwa.
Ukuguga kusengakapheli kwe-placenta kuholele ezinhlobonhlobo ezimbi, futhi umphumela walesi simo yi-intrauterine yokuhlupheka kwengane. I-placenta igcwalisa kahle imisebenzi yayo, ingane ithola oksijini kancane kanye nezakhi, ukuthuthukiswa kwayo kuyanciphisa. Lokhu kungaholela ekufeni kwe-fetus nokuzalwa komntwana omncane nobuthakathaka.
Isimo singalungiswa ngemithi - zama ukuthuthukisa ukushintshaniswa kwezakhi kanye ne-oxygen.
