I-dopplerometry ye-fetal yenye yeendlela ezongezelelweyo zokufunda imeko yengane, injongo yayo ukuseka uhlobo kunye nokukhawuleza kokuhamba kwegazi kwi-"fetal-placenta-mother" system. Olu hlalutyo lubaluleke kakhulu, kuba lenza kube lula ukufumanisa ukusilela kwe-fetoplacental kwixesha lokukhulelwa kwentuthuko yesisu esiswini. Ngokuqhelekileyo, i-doppler yenziwa kwi-trimester yesithathu yesigxina, njengoko inkqubo yokuhambisa isondela. Uphononongo luqhutyelwa kusetyenziswa isenzi esikhethekileyo esixhomekeke kumshini oqhelekileyo we-ultrasound.
Umgaqo we-ultrasound of fetus ene-dopplerometry
Le ndlela isetyenziswe ngempumelelo kwisenzo malunga nekota yeshumi leminyaka, eyaba yenzeke ngenxa yokulula kwayo, ukuqonda nokukhuseleko. Ingundoqo yempembelelo yeDoppler yile ndlela ilandelayo: Ukunyanzeliswa kwe-ultrasonic ene-frequency echanekileyo imiswe kwiimfucu kwaye ibonakala kwiiseli ezibomvu zegazi ezihambayo. Ngenxa yoko, i-ultrasound eboniswa yi-erythrocytes ibuyiselwa kwi-sensor, kodwa i-frequency yayo sele ishintshiwe. Ubukhulu beenguqu ezenzeke kwixesha elimisiweyo le-ultrasound, kwaye ziya kubonisa ulwalathiso kunye nokukhawuleza kokuhamba kwamaseli obomvu.
Ziziphi iimpawu ze-dopplerometry yobusana ezifunekayo?
Olu hlobo lwesifundo lufanelekileyo kwimeko apho kukho ukuphulwa kwendlela yokuphuma kwegazi ye-uterine. Abasetyhini abasemngciphekweni basengozini:
- i toxicosis;
- xi nzelelo;
- pyelonephritis;
- Ukwanda kweenkqubo zezicubu ezixhumeneyo;
- isifo sikashukela;
- ukungqubuzana komama nomntwana kunye nokunye.
Kwakhona, kukho imfuneko yokuba i-dopplerometry yeenqwelo ze-fetal, ngakumbi kwiimeko apho i-ultrasound ibonakalisa iziphazamiso ezilandelayo ekuphuhlisweni kwayo:
- ukuvuthwa kwangaphambili kwilungu le-placental;
- utywala ;
- ubukhulu bomntwana abufananga nexesha lokugaya;
- ukungabikho komntwana osweleyo kunye neziphene zesisu senhliziyo;
- uphuhliso olungalunganga lwabantwana xa bevelisa iziqhamo ezininzi;
- ukuphoxiswa kwengqondo yentloko kwintsana;
- ukukhunjulwa kwezifo ze-chromosomal;
- Ukukhula okungafanelekanga kwintambo yomdaka kunye nezinye izinto ezingaqhelekanga ekuphuhlisweni.
Uthini umahluko phakathi kwe-doppler yokuphulaphula iintliziyo zenhliziyo kunye ne-ultrasound?
Ukwahlukana okubaluleke kakhulu kukuba idatha efunekayo efunyenwe ngoncedo lwee-device zixhobo zifundwa kumfanekiso omnyama nomhlophe. I-Doppler inikeza umfanekiso wesimboli kuphela. Isifundo esinjalo "imibala" yonke imilambo yegazi kwiinqanawa ezahlukahlukeneyo kunye nemibala, exhomekeke ngokupheleleyo kwisantya sokuhamba kweeseli ezibomvu zegazi kunye nendlela yazo.
Inkcazo ye-fetal doplerometry
Iziphumo zolu cwaningo zixutyushwa bhetele kunye nogqirha, kuba iimashishini ezahlukeneyo ze-ultrasound ziyakunikwa iifomfayile zazo. Inqaku eliqhelekileyo yile:
- Umlinganiselo we-SDO-systolic-diastolic, osekwe umthamo ngamnye ngokwahlukeneyo kwaye uthetha umgangatho wokunyakaza kwegazi kuwo;
- I-IPC - ukunyuka kwama-bloodplantation of blood, ukubonakalisa ubukho bokungaphumeleli kwinkqubo yokuhamba kwegazi phakathi kwezi zitho;
- Ukunqongophala kwe-FPN-change-placental, ukuphazamiseka kwimizi yokuphuma kwegazi kwi-"child-placenta" system.
Kukho nezinye izibhengezo kunye nezifinyezo ezibonisa indawo yophando, iinkqubo, ukuphambuka nezinye izinto.
Kubalulekile ukuqonda ukuba imigaqo ye-dopplerometry ye-fetus yinkcazo efakazela ukungabikho kwanophina ukuphulwa kwinkqubo yokwenza uhlalutyo. Musa ukukwesaba ukuba uphando lufumene ukuphuka. Iyeza zanamhlanje zinalo "i-arsenal" eyaneleyo ukuze kulungiswe inkqubo yesigxina.
