I-placenta iyilungu eliqinisekisa ukukhula okujwayelekile nokuthuthukiswa kwe-fetus. Ukuvuthwa kwe-placenta kunezigaba ezine. Kusukela ekuqaleni kokukhulelwa kuze kufike isonto lama-30 kukhona inqubo yokwakha. Kuze kube liviki engamashumi amathathu nesithupha, liyakhula. Isiteji sokuvuthwa sisuka kumashumi amathathu nesine kuya kwesonto engamashumi amathathu nesithupha, futhi kusukela evikini lesithathu nesikhombisa lokukhulelwa, i-placenta iguga. Ngemuva kokubeletha, lesi sitho siphume njengesiphetho.
Isiqu sokuvuthwa kwe-placenta sinqunywa yi-ultrasound.
Yini ukuvuthwa ngaphambi kwesikhathi kwe-placenta kusho?
Izinqubo zokuvuthwa nokuguga, okwenzeka ngesikhathi esincane sokuhola, zingahlotshaniswa nezici zomuntu ngamunye futhi zingabi nengozi kumntwana kanye nomama.
Uma izinga lokuvuthwa kwe-placenta lidlula ubude bokukhulelwa nokuqhekeka okuphawulekayo, lokhu kusho ukuthi lo wesifazane cishe uzoguga ngaphambi kwesikhathi i-placenta. Lokhu kutholakala kufanele kuthathwe ngomthwalo wemfanelo, ngoba ukuvuthwa okusheshayo kwe-placenta kubiza ukusebenza kwayo, futhi ingane ngeke ikwazi ukuthola ngokugcwele i-oxygen nezakhi ezivela emzimbeni womama. Ngesikhathi sokuguga, indawo ye-exchange surface isinciphisa, kwezinye izindawo usawoti ungafakwa.
Okuyingozi kakhulu ukuvuthwa ngaphambi kwesikhathi kwe-placenta, yi-hypoxia kanye ne-hypotrophy ye-fetal. Ukwelashwa okunjalo kungabangela ukwephulwa kwegazi lomntwana. Ukuguga kwangaphambi kokuqala kwe-placenta kusongela ukuthola i-placenta, ukukhishwa okungenakuphela kwe-amniotic fluid nokukhulelwa kwesisu. Lesi sifo singabangela ukwehluka ekuthuthukiseni ubuchopho, futhi kwezinye izimo ngisho nokukhulelwa kwesisu. Ukuze ugweme lezi zifo, kuyadingeka ukuba ufunde ukwelashwa ngesikhathi futhi uhlolwe njalo udokotela.
Izimbangela zokuvuthwa ngaphambi kwesikhathi kwe-placenta
Lezi zifo zingadala izici eziningana:
- ukuphambene nomkhuba wesisindo somzimba wesifazane okhulelwe, kungaba kokubili ukukhuluphala nokuqina;
- ukuphazanyiswa kwesakhiwo sezindumbu zesisu nokudla kwayo - lezi zinguquko zingenzeka ngenxa yomlando wokukhipha isisu noma ukubeletha okunzima;
- ukulimala kwesibeletho ngenxa yemithonya yemishini;
- izifo zesimiso se-endocrine, isibindi, uhlelo lwe-urinary;
- isifo se-circulatory system;
- izifo ezingelapheki, izifo ezithathelwanayo;
- ukubhema;
- I-Rhesus-impikiswano ;
- gestosis yesikhathi eside;
- i-toxicosis yokuqina okukhulu.
Ngokuvamile, ngokuguga kusenesikhathi ngaphambi kwe-placenta, azikho izimpawu. Thola ukuthi le nqubo kungenzeka kuphela ngosizo lwe-ultrasound. Ngesikhathi sokucwaninga, fanisa ubukhulu be-placenta bese uqhathanisa okutholakele ngesikhathi sokukhulelwa. Futhi, kusetshenziselwa idatha yobuningi bayo kanye nokuqoqwa kwamanoni e-calcium.
Ukwelashwa kokuvuthwa ngaphambi kwesikhathi kwe-placenta
Ukwelashwa kwalesi sifo sekuqala emva kokuthola imiphumela eqinisekisiwe yokuhlolwa okuyinkimbinkimbi. Okokuqala, qeda izinto eziyingozi futhi usebenzise ukwelashwa kwezidakamizwa eziyinkimbinkimbi
Kwezinye izimo, kubalulekile ukuvakasha esibhedlela. Ngemuva kwenkambo yokwelashwa, phinda i-ultrasound, i- doppler ne-KTG. Ukuze kuzalwe ingane enempilo, umsebenzi ngokuvamile uqala ngaphambi kwesikhathi. Kulesi simo, ukuvuselelwa kwemisebenzi kwenziwa ngokwemithi.
Ukwazi ukuthi kusho ukuthini ukuvuthwa ngaphambi kwesikhathi ngaphambi kokuvuthwa kwe-placenta futhi kuyini imiphumela yalo, umama olindelekile kufanele aziqaphele yena, alandele izincomo zodokotela futhi angazibandakanyi nemithi.
