I-Doppler okanye, ngokulula, i-doppler ekukhuleleni-le enye yeendlela ze-ultrasound. Isetyenziswe kwiimeko xa kuyimfuneko ukuvavanya ngokuchanekileyo ubudlelwane phakathi koomama nomntwana ngokuqhutyelwa kokujikelezwa kwe-placental. Eyona nto ibaluleke kakhulu, le ndlela yokuxilongwa ikhona, ukuba ibhinqa linenkinga yokuqhawula. Ngenxa yeDoplerography, kunokwenzeka ukuba uchane ngokuchanekileyo indawo yendawo nganye kwaye uqinisekise izinga lokuhamba kwegazi kunye nalo.
Ukungenakwenzeka kunye ne-dopplerography yabesetyhini abakhulelweyo kukukhuseleko kunye nomxholo wenkcazelo ephakamileyo. Olu phofu lubonisa nakwiiyure zokuqala, okwenza kubaluleke kakhulu kwiinkqubo zokuxilongwa kwe-perinatal. Ngokomzekelo, kwiiveki ezi-5 ukuya ku-6 ngoncedo lwe-doppler ultrasound lunokulinganisela ukuhamba kwegazi kwimibhobho yesisu. Oku kwenza ukuba ukwazi ngaphambili malunga neengxaki zexesha elizayo, umzekelo, malunga nokulibaziseka kokukhula kokukhula komntwana.
Nini ukwenza i-doppler ngexesha lokukhulelwa?
I-ultrasound yokuqala kunye ne-doppler iyimfuneko ekufuneka iqhutywe kwithuba ukusuka kwi-20 ukuya kweveki ye-24. Oku kudibaniswe nelokuba ngeli xesha i-hemostasis iziphazamiso zenzeka kumfazi okhulelweyo, kunye nomngcipheko wophuhliso lwe-hypoxia, i-gestosis, ukukhawuleza kokukhula kwe-intrauterine kunye nophuhliso lomntwana oluphezulu.
Uhlolo oluphindaphindiweyo lokuhlola i-doppler kwabasetyhini abakhulelweyo kaninzi luqhutywa kwithuba ukusuka kwi-30 ukuya ku-34 ngeveki. Kule nqanaba, i-doplerography isinceda ekuhloleni olubunzima lokukhula nophuhliso lomntwana.
Izibonakaliso ezikhethekileyo zokutshatyalaliswa kweentlobo zabasetyhini abakhulelweyo
Ukongeza kwenkqubo yokuhlola i-Doppler, ungadinga ukufumana inkqubo eyongezelelweyo ye-Doppler ultrasound njengoko ilawulwa ngugqirha. Oku kuyimfuneko ukuba unayo nayiphi na ingxaki zempilo okanye izibonakaliso ezizodwa, njenge:
- isifo sesifo, isifo sikashukela, uxinzelelo lwegazi;
- iingxaki kwi-hemostasis;
- gestosis;
- I-Rhesus-imfazwe phakathi koomama nomntwana;
- ukukhulelwa okubanzi;
- ubukho bentsholongwane ekukhulelweni kwangaphambili;
- ukungafani ngokukhululeka komntwana kunye nexesha lokukhulelwa.
Ukutshatyalaliswa kweengxaki zokukhulelwa kunye nokuphazamiseka kwamaplacental
Ngaphambili, indlela yokubeka i-placenta isetyenziselwa ukufunda isithuba sepentecenta nokuphuhliswa, ubuncinane bokubakho ukuhlolwa kwe-radiographic kwesibeleko sokuchonga indawo ye-placenta kuyo. Le ndlela yaqwalaselwa ngokuthe xaxa xa kuthelekiswa nophando lwe-radiography. Nangona kunjalo, ngoku le ndlela ichithwa ngokupheleleyo yindlela yokusebenzisa i-ultrasound ye-placenta yophando.
I-ultrasound ye-placenta ayenzwanga nje kuphela ukucacisa indawo yayo, kodwa kwakhona ukuqinisekisa ukuxilongwa (okanye ukupheliswa kwayo) kokuphazamiseka kwangaphambili kweplantal. Ngelishwa, le nzekayo ikhona, nangona kunjalo, phakathi kwabasetyhini abakhulelweyo.
Phantse kwi-3% yabasetyhini inqanaba lokukhulelwa luyinkimbinkimbi ngokuphazamiseka kwembulunga. Ukuphulwa okunjalo kwikhosi yokukhulelwa kwenzeka ngenxa yesakhiwo esingalunganga seemithambo yegazi kwi-placenta okanye kwisibeletho. Ukuphulukisa i-pathology kunokubangela izinto ezifana nesifo sikashukela,
Iimpawu ze-detache ye-placenta zingabonakalisa kwi-vaginal, intlungu enzima kwisisu esiswini. Inkqubo inokuhamba kunye nokuphuma kwegazi ngaphakathi kunye nokuphulwa kwe-intrauterine yophuhliso lwexesha elizayo lomntwana. Ngamanye amaxesha imeko iholela ekufeni kwakhe.
I-Dopplerometry ene-detachment ibonisa ukuphulwa okunzulu entliziyweni yesisu somntwana. Uphononongo lubangela ukuba kube lula ukuqonda ngokuthe ngqo indlela inkqubo ehambe ngayo kwaye yintoni ingozi kumntwana. Ngokusekelwe kulolu cwaningo, isigqibo senziwe ngonyango olunyango.
