I-dopplerometry ye-Fetal ingenye yezindlela ezengeziwe zokutadisha isimo somntwana, inhloso yalo ukusekela isimo kanye nokusheshisa kwegezi legazi "ohlelweni lomama-fetal-mother". Lokhu kuhlaziywa kubaluleke ngokukhethekile, ngoba kwenza kube lula ukukhomba ukulahlekelwa kwesifo sokudoba ekukhulekeleni kwentuthuko ye-fetal esibelethweni. Ngokuvamile, i-doppler yenziwa ku-trimester yesithathu yokubeletha, njengoba inqubo yokulethwa isondela. Ucwaningo lwenziwe ngokusebenzisa inzwa ekhethekile ehlanganiswe nomshini ojwayelekile we-ultrasound.
Isimiso se-ultrasound ye-fetus ene-dopplerometry
Le ndlela isetshenziswe ngempumelelo ekusebenzeni cishe ingxenye yesine yekhulu leminyaka, eyenzeka ngenxa yokulula kwayo, ukwazisa nokuphepha. Okuyinhloko yomsindo we-Doppler kanje: ukuduma kwe-ultrasonic okunomvuthwandaba ocacile kuthunyelwe ama-tissu futhi kubonakala kusuka kumaseli abomvu egazi. Ngenxa yalokho, i-ultrasound eboniswa i-erythrocyte iphindiselwa emuva kwenzwa, kodwa imvamisa yayo ishintshiwe kakade. Ubukhulu bezinguquko ezenzeka emvamisa wamisiwe we-ultrasound, futhi zizobonisa isiqondiso nesivinini sokuhamba kwamaseli abomvu egazi.
Iziphi izinkomba ze-dopplerometry yesisu ezidingekayo?
Lolu hlobo lokutadisha lubalulekile uma kwenzeka kukhona ukwephulwa okungenzeka kwegazi le-uterine ye-placental. Abesifazane abasengozini basengozini:
- i-toxicosis ephuzile;
- i-hypertension;
- i-pyelonephritis;
- ukwanda kwesistimu yezicubu ezixhunyiwe;
- isifo sikashukela mellitus;
- ukuxabana komama nezingane kanye nokunye okunye.
Futhi, kuvame ukuba nesidingo se-dopplerometry yemikhumbi ye-fetal, ikakhulukazi ezimweni lapho i-ultrasound ibonisa khona ukukhathazeka okulandelayo ekuthuthukiseni kwayo:
- ukuvuthwa kokuqala kwendikimba ye-placental;
- ubunikazi obucacisiwe ;
- ubukhulu bomntwana abufani nesikhathi sokubeletha;
- ukungabikho kokuzalwa okungenasifo kanye nezinkinga zomzimba wenhliziyo;
- ukuthuthukiswa okungalungile kwezingane lapho kuthwala izithelo eziningana;
- ukwehla kobuchopho bekhanda emntwaneni;
- ukutholakala okusolakala kwezifo ze-chromosomal;
- ukukhula okungalungile komthamo womzimba nezinye izinto ezingavamile ekuthuthukisweni.
Uyini umehluko emkhatsini we-doppler ekulaleleni izinhliziyo zenhliziyo yakho kanye ne-ultrasound?
Umehluko ophawulekayo wukuthi idatha edingekayo etholakala ngosizo lwamadivaysi e-ultrasound afundwa emfanekisweni omnyama nomhlophe. I-Doppler inikeza isithombe sombala kuphela. Ucwaningo olunjalo "imibala" yonke imifudlana yegazi ezitsheni ezinemibala ehlukene nemibala, encike ngokuphelele ekuvinjeni kokuhamba kwamangqamuzana egazi abomvu nomzila wabo.
Incazelo ye-doplerometry yesisu
Imiphumela yocwaningo ixoxwa kangcono nodokotela, ngoba imishini ehlukile ye-ultrasound ingahlushwa isifingqo sayo. I-notation ejwayelekile kunazo zonke:
- Isilinganiso se-SDO-systolic-diastolic, esungulwa iseri ngayinye ngokwehlukile futhi sisho ikhwalithi yegazi ukunyakaza kuyo;
- I-IPC - ukunyakaza kwegazi okwegazi, okuveza ukuthi kukhona ukwehluleka kwesistimu yegazi lokugeleza phakathi kwalezi zitho;
- Ukuntuleka kwe-FPN, ukuphazamiseka kwegazi kugeleza ohlelweni lwe "baby-placenta".
Kunezinye izinkomba kanye nezifinyezo ezibonisa indawo yocwaningo, izinkambiso, ukwehluka nezinye izici.
Kubalulekile ukuqonda ukuthi imigomo ye-dopplerometry ye-fetus yizinkomba ezifakazela ukungabi khona kwephulwa ekuqhubeni ukuhlaziywa. Ungesabi uma isifundo sitholile ukwehluka. Imithi yesimanje ine "arsenal" eyanele ukuze ilungise inkambo yokubeletha.
