I-Cardiotocography iyindlela ewusizo yokurekhoda inhliziyo yenhliziyo yengane kanye nokwehlukana kwezibeletho zowesifazane okhulelwe. Kuze kube manje, i-CTG ekukhulelweni yingxenye ebalulekile yokuhlolwa kwe-fetus, ngoba le ndlela ibonisa ukuthi kukhona yini ukwehluleka ekuthuthukisweni kwayo.
Imiphumela ye-CTG ngesikhathi sokukhulelwa kusiza ngendlela efika ngesikhathi ukuthola izinkinga zokuthuthukiswa kwenhliziyo yengane nokubeka ukwelashwa okwanele. Ngezinye izikhathi ukuwohloka kwe-fetus kudinga ukulethwa kwezimo eziphuthumayo.
I-CTG yenzelwa abesifazane ngesikhathi sokukhulelwa isikhathi samasonto angama-30-32, ngoba phakathi nalesi sikhathi izinkomba ziyoba nenembile kakhulu. Kukhona imishini entsha yesimanje evumela ukuthi wenze CTG, kusukela ngamasonto angu-24, kodwa lokhu akuvamile. I-Cardiotocography nayo yenziwa ngesikhathi sokubeletha. Ngokujwayelekile i-CTG inconywa ukuthi yenziwe kabili ngesikhathi sesithathu. Kodwa uma ukukhulelwa kwenzeka ngezinkinga, khona-ke i-CTG ingakhetha enye. Izizathu zokuhlolwa okungeziwe:
- izifo ezingapheliyo;
- I-Rhesus-impikiswano ;
- ukungabi namanzi;
- ukukhubazeka kokuzalwa komntwana;
- ukukhulelwa ngaphambi kwesikhathi;
- kunciphise umsebenzi we-motor of the fetus;
- usongo lokukhulelwa kwesisu;
- inqola ngaphambi kwesikhathi se-placenta.
Ukucacisa imiphumela ye-CTG ekukhulelwe
KUBALULEKILE! Udokotela wezifo zokwelapha kuphela owazi ukuthi angayichaza kanjani i-CTG ekukhulelwe. Ngokujwayelekile udokotela akatshele isiguli yonke imininingwane yocwaningo, ngoba kunzima ukuyiqonda konke lokhu ngaphandle kolwazi oluyisisekelo. Udokotela nje ukhuluma ngokubakhona kweziphambeko noma ukungabi khona kwabo.
Lapho udokotela echaza i-CTG, kumele anqume izinkomba eziningana ezibonisa izimpawu ezivamile Lezi zimpawu zenza kube lula ukuhlola isimo
Ngakho-ke, uma umphumela we-CTG ekukhulelweni kubonisa kusuka ku-9 kuya ku-12 amaphuzu, kusho ukuthi ingane ayitholanga okungajwayelekile ekuthuthukisweni. Kodwa ngezikhathi ezithile kuyadingeka ukuba kugcinwe. Uma ngesikhathi sokukhulelwa ngenxa yombuzo we-CTG ubonise 6.7, amaphuzu ayisishiyagalombili, kubonisa ukuthi i-hypoxia elinganisiwe (i-oxygen starvation), okuwukuphambene nokujwayelekile. Amakhombisi angaphansi kwamaphuzu ayisihlanu abonisa ukuthi usongela impilo yobusana, ngoba unesifo esikhulu se-oxygen. Ngezinye izikhathi ukuxazululwa kokuzalwa ngaphambi kwesikhathi ngaphambi kokuba kutholakale isigaba sokudla kuyadingeka.
