I-Doppler noma, ngokulula, i-doppler ekukhulelwe - lena enye yezindlela ze-ultrasound. Isetshenziswe ezimweni uma kudingeka ukuba uhlolisise ngobuhlobo ubuhlobo phakathi komama nomntwana ngokucubungula ukusabalalisa kwe-placental. Okubaluleke kakhulu, le ndlela yokuxilongwa ifinyelele, uma owesifazane enesifo sokuvala. Ngenxa yeDoplerography, kungenzeka ukuba unqume ngokunembile indawo yesitsha ngasinye bese unquma izinga lokuhamba kwegazi kulo.
Ukudideka okungabonakali kwamanye amazwe abesifazane abakhulelwe ukuphepha nokuqukethwe okuphezulu kwelwazi. Lesi sifundo sibonisa ngisho naseziqenjini zokuqala, okwenza kubaluleke kakhulu ezindleleni zokuxilonga nge-perinatal. Isibonelo, emasontweni ama-5-6 ngosizo lwe-doppler ultrasound angakwazi ukukala ukugeleza kwegazi emithanjeni yesibeletho. Lokhu kwenza ukwazi ukuthi kusengaphambili ngezinkinga ezizayo, isibonelo, mayelana nokulibaziseka kokuthuthukiswa komntwana.
Nini ukwenza i-doppler ngesikhathi sokukhulelwa?
I-ultrasound yokuqala ene-doppler iyadingeka ukuba yenziwe ngesikhathi sokusukela ngesonto lama-20 kuya ku-24. Lokhu kuhlotshaniswa neqiniso lokuthi ngalesi sikhathi ukuthi i-hemostasis izifo zivela kowesifazane okhulelwe, kanti futhi ingozi yentuthuko ye-hypoxia, gestosis, ukukhulelwa kwe-intrauterine ukukhula nokuthuthukiswa kwe-fetus kuphakeme.
Ukuhlolwa okuphindaphindiwe kwe-doppler kwabesifazane abakhulelwe kuvame ukuqhutshwa esikhathini esivela ku-30 kuya kwesonto lama-34. Kulesi sigaba, i-doplerography isisiza ekuhloleni okuyinkimbinkimbi kokukhula nokuthuthukiswa kwengane.
Izinkomba ezikhethekile zokudonswa kwamagama abesifazane besifazane abakhulelwe
Ngaphandle kokuhlola okuvamile kwe-Doppler, kungase kudingeke ukuba wenze inqubo eyengeziwe ye-Doppler ultrasound njengoba iqondiswa udokotela. Lokhu kuyadingeka uma unenkinga yezempilo noma izinkomba ezikhethekile, njenge:
- isifo sezinso, isifo sikashukela, umfutho wegazi ophakeme;
- ukuphazamiseka ohlelweni lwe-hemostasis;
- i-gestosis;
- I-Rhesus-impikiswano phakathi komama nengane;
- ukukhulelwa okuningi;
- ukutholakala kwamathambo ekukhulelwe kwangaphambilini;
- ukungalingani ngobukhulu be-fetus kanye nesikhathi sokukhulelwa.
Ukunyathelisa ukukhulelwa ngokuphazamiseka kwamapayipi
Esikhathini esidlule, indlela ye-placenta yasetshenziselwa ukutadisha isikhundla se-placenta kanye nokuthuthukiswa, okuyisisekelo sokuhlolwa kwe-radiographic kwesibeletho sokunquma indawo ye-placenta kuwo. Le ndlela ibhekwa njengokungafani nokuqhathaniswa nocwaningo lwe-radiographic. Kodwa-ke, manje le ndlela ishintsha ngokuphelele ngezindlela ze-ultrasound zocwaningo lwe-placenta.
I-ultrasound ye-placenta ayenzelwe ukucacisa indawo yayo kuphela, kodwa futhi ukuqinisekisa ukuthi ukuxilongwa (noma ukuqedwa kwayo) kokuphazamiseka kwe-placental ngaphambi kwesikhathi. Ngeshwa, lesi simo senzeke phakathi kwabesifazane abakhulelwe, noma kunjalo.
Cishe ngo-3% wabesifazane inkambo yokukhulelwa ilukhuni ngokuphazamiseka kwamapayipi. Ukwephula okunjalo inkambo yokukhulelwa kubangelwa isakhiwo esingalungile semithambo yegazi ku-placenta noma esibelethweni. Ukuvusa i-pathology kungaba nezinto ezifana nesifo sikashukela,
Izimpawu zensimbi ye-placenta zingase zibonakale kusuka kwesifazane, ubuhlungu obunzima esiswini esingaphansi. Le nqubo ingahambisana nokuphuma kwe-intrauterine nokuphulwa kwe-intrauterine ukuthuthukiswa kwekusasa lomntwana. Ngezinye izikhathi isimo siholela ekufeni kwakhe.
I-Dopplerometry ene-detachment yembula ukuhlukumeza okuqinile enhliziyweni yomculo we-fetus. Ucwaningo lwenza kube lula ukucacisa kahle indlela inqubo ehambe ngayo nokuthi yini engongela ingane. Ngokususelwa kulolu cwaningo, isinqumo senziwa ngokuphathwa okuphuthumayo.
