I-Cardiotocography (CTG) ye-fetus iyindlela elula futhi ephephile yokuhlola isimo nesilpitation of the fetus. Ngokwesilinganiso, kunconywa ukuba kwenziwe, kusukela ngeviki lama-26 lokukhulelwa. Amagama angaphambilini ayibonakali, ngoba kunzima ukuthola ijika elifanele futhi, ngisho nangaphezulu, ukulihumusha ukuze uthole izimpendulo zemibuzo yesithakazelo.
I-CTG iboniswe nini?
I-Cardiotocography iyindlela yokuqapha isimo se-fetal. Futhi uma ngaphambilini nje kuphela i-stethoscope esetshenziselwa ukuhlola ukushaya kwenhliziyo yakhe, namuhla indlela enokwethenjelwa yokulinganisela izinga lokushaya kwenhliziyo yengane ngokusizwa kwedivayisi ye-cardiotocography yasungulwa. I-KGT ihlinzekwa kubo bonke abesifazane abakhulelwe okungenani kanye nakwi-trimester yesithathu. Okufanelekile, kufanele kwenziwe izikhathi ezingu-2 ukuze uthole ulwazi oluthe xaxa mayelana nomsebenzi wenhliziyo encane.
Ngokuvamile ucwaningo lwenziwa eziningana zamacala, njenge:
- ukukhulelwa okuningi;
- I-Rhesus-impikiswano;
- ukuzalwa ngaphambi kwesikhathi, ukukhipha isisu, ukukhulelwa kwesisu;
- i-toxicosis eqinile;
- umzwelo wokunciphisa umsebenzi wesisu (uma owesifazane ezwa ukunciphisa inani nenani lokuthuthumela emntwaneni);
- ukungabi namanzi;
- ukukhulelwa ngokweqile;
- ukubambezeleka noma ukulimala kwe-fetus;
- ukuguga kwasekuqaleni kwe-placenta;
- ukuphazamiseka kwegazi, okwembulwa yi-ultrasound-doppler.
Izinhlobo ze-cardiotocography
Kunezinhlobo ezimbili ze-CTG - ngqo futhi engaqondile. Ngokungaqondile kuyasetshenziswa ngesikhathi sokukhulelwa nokubeletha, lapho isambiso sesisu sisengakacacile. Kulesi simo, izinzwa zifakwe kwamaphuzu athile - amaphuzu we-signal engcono kakhulu yokufika. Lesi yisifunda esibelethweni nasendaweni lapho inhliziyo ye-fetal ilalela khona kancane kancane.
Nge-CTG eqondile, izinga lokushaya kwenhliziyo lilinganiswa ne-needle electrode ejikelezayo, eqondiswa emzimbeni emgodini we-uterine.
I-Cardiotocography (FGT) - okulotshiwe
Indlela yokufunda i-cardiotocography (CTG) ye-fetus ngokuqinisekile iyayazi udokotela, ngakho-ke methemba leli cala kuye. Udinga nje ukwazi ukuthi yiziphi izinkomba ezicatshangelwayo phakathi nocwaningo. Phakathi kwabo - imvamisa evamile yesigqi se-basal (inhliziyo) (ngokuvamile i-120-160 ishaya ngeminithi), i-reflex ye-myocardial, ukuhluka kwezinga lenhliziyo, izinguquko ngezikhathi ezinkingeni zenhliziyo.
Futhi uma ukucacisa i-cardiotokorafii ye-fetal zonke lezi zinkomba kucatshangelwa - lokhu kuyadingeka ekuhloleni komgomo wemiphumela. Kumele ulalele ngokucophelela udokotela bese ulandela iseluleko sakhe uma kukhona okungajwayelekile okuveziwe.
