Yenziwa njani inkqubo?
Ngaphambi kokuba i-dopplerography of fetus, ugqirha ugqiba indawo ephantsi kophando: iinqanawa zokuhamba kwegazi, iinqanawa zeengqondo, intliziyo, isibindi. Ngokusebenzisa umsebenzi weDoppler nokuthumela inzwa kwilungu phantsi koviwo, ugqirha uya kufumana umfanekiso kwiskrini. I-apparatus iya kuhlalutya le data ngokwayo. Inkqubo ayibuhlungu nakwixesha elifutshane-imizuzu eyi-10-15.
Ngaba wonke umntu ochazwe ngokuchaneka?
Ukutshatyalaliswa kwegazi ngokuphambuka kwegazi kumiselweyo kubo bonke abafazi abakhulelweyo ngeveki ye-32 yokuzala umntwana. Kwimeko yeempawu ezizodwa (ukungenakulungelelaniswa kwendawo, ukungathandabuzeki kokukhawuleza kokukhula kwe-intrauterine), isifundo singaqhutyelwa ngaphaya kwexesha elibonisiweyo (iiveki ezingama-22-24).
I-Dopplerography imiselwe kwakhona kwiimeko ezifana nale:
- ukukhulelwa okubanzi;
- I-Rhesus-fetus kunye nengxabano yomama.
Kwakhona, kwiimeko apho iiparameter zomzimba zentsholongwane azihambelani neminyaka yobudala, i-ultrasound ye-fetus ene-dopplerography ingabelwa ukuvavanya imeko yokuhamba kwegazi.
Ziziphi iipameters ezifunyenwe kwiDoppler?
Ingqikithi, kukho iirriyiti ezi-2 kunye ne-1 mvini kwintambo ye-umbilical, eyinika intombazane enezondlo kunye ne-oxygen. Ngoko ke, emthonjeni igazi liya kwintsana ngqo kwi-placenta. Ngomlanjeni, iimveliso ezivela ekuvuneni zisuswa kumntwana.
Ukusebenza ngokuqhelekileyo kokujikeleza kwegazi, ukuxhathisa kwiindonga zombane kufuneka kube phantsi. Kwimeko yokunciphisa isitya, ukulahleka kwe-oxygen kukhula, okuchaphazela kakubi ukuphuhliswa kwe-intrauterine.
Ziziphi iziphazamiso zokuhamba kwegazi ezinokufunyanwa ngeDoppler?
Xa wenza i-dopplerography of vessels ye-fetal, ezi zilandelayo zibonakaliswe:
- ukujikeleza kwegazi,
- uxinzelelo lweengcambu,
- ukunyaniseka kwemithambo yegazi.
Xa kuthelekiswa iimpawu ezifunyenweyo, izifo ezahlukahlukeneyo zokuhamba kwegazi ziyafumaneka. Ngoko, yabela:
- Iidanga eli-1 A - xa kukho ukungasebenzi kakuhle kwi-system ye-utero-placental blood system, kodwa i-systemal fetal system isebenza ngokuqhelekileyo;
- I-degree eyi-B - ibonakala xa inkqubo ye-fetus-placenta ikhubazekile, kwaye ukuphuma kwegazi okungapheliyo akukho mphazamiseko;
- I-degree 2 - kwiimeko apho ukuphulwa kubakho ngokukhawuleza kwiinkqubo ezi-2, kodwa azibalulekanga;
- Iidanga ezi-3 - ziyakubonwa xa ukuphulwa komgaqo we-placenta ebaluleke kakhulu, kwaye ukuphuma kwegazi kuphazamiseka.
Kwinqanaba eli-1 lokuphula umthetho, ibhinqa elikhulelweyo liyabonwa kwithuba elisele. Iimviwo kunye ne-ultrasound zenziwa kanye ngeveki. Ngexesha elifanayo, ukuba i-CTG eqhubekileyo ayizange ibonakalise naziphi na ukuphulwa kunye nosongelo lokuqhubeka nokukhulelwa, ukuzalwa kwenzeka ngexesha.
Ngama-3 degrees of violations, ibhinqa iphantsi kweliso lugqirha ngabagqirha, kwaye phambi kwezinto zokusongela ukukhulelwa, icandelo lesahara liya kwenziwa.
Ngaloo ndlela, i-dopplerography ye-fetus yindlela yokwenza uphando eyenza ukuba ukuhamba kwegazi kuhamba ngokuqhelekileyo kwaye ingaba ubunzima bubuhlungu bubuhlungu kulo mba.
