Kunezindlela ezimbili zokwenza i-CTG ye-fetus ngesikhathi sokukhulelwa - ukuhlolwa kwangaphakathi nangaphakathi.
Ngaphandle kwe-CTG yangaphandle esiswini sowesifazane okhulelwe, i-ultrasound sensor ifakiwe, elungisa isigqi senhliziyo nenani lehliziyo. Le ndlela isetshenziswa kakhulu kokubili ngesikhathi sokukhulelwa futhi, ngokuqondile, ngomsebenzi. I-Internal, noma i-CTG eqondile, ilinganisa ithoni yesibindi nesibindi se-intrauterine ngesikhathi sokubeletha. Inzwa ye-tensometric isetshenziswe, ehlanganiswe nekhanda le-fetus ngesikhathi sokubeletha.
Imiphumela yocwaningo iphuma ngedivayisi ngesimo somfanekiso ocacile kwi-tape ende ende. Kule nkinga, ukukhishwa kwesibeletho nokuhamba kwemvuthu kukhishwa njengekhava engxenyeni engezansi ye-tape.
Ngabe i-CTG fetus iphi?
Njengomthetho, hhayi emavikini angama-28. Okufundiswa kakhulu yi-cardiotocography kusukela ngesonto lama-32. Kusukela ngalesi sikhathi ingane ingavele isasebenza imizuzu engu-20-30.
Ngakho-ke, ku-trimester yesithathu, ngezinkomba ezijwayelekile, owesifazane okhulelwe kumele ahambe nge-KTG okungenani izikhathi ezimbili. Ukuhlolwa kwenziwa ngesisu esingenalutho noma amahora ambalwa ngemva kokudla. Ebusuku kuyinto efiselekayo ukuzama ukuphumula okuhle. Ngesikhathi se-KGG, owesifazane okhulelwe uhlala noma alele eceleni kwakhe. Ngokwesilinganiso, inqubo ayihlali isikhathi esingaphezu kwemizuzu engu-30-40, futhi kwezinye izimo, imizuzu engu-15-20 yanele.
Norm yemiphumela ye-CTG ye-fetus
Emva kokuhamba kwesifundo kunzima kakhulu ukuqonda imiphumela. Yini i-CTG yesisu?
Ngenxa yocwaningo, udokotela uthola idatha elandelayo: isilinganiso se-basal senhliziyo noma, izinga lokushaya kwenhliziyo (evamile - 110-160 ukushaya ngomzuzu ngokuphumula kanye no 130-180 - esigabeni esisebenzayo); i-tokogram noma umsebenzi we-uterine; Ukuhlukahluka kwesigqi (ukuphakama okujwayelekile kokuphambuka kusuka kwenhliziyo kungaba kusuka ku-2-20 imivimbo); Ukusheshisa - ukusheshisa kwenhliziyo (kungakapheli imizuzu engu-10 kusuka kokubili noma ngaphezulu); Ukunciphisa - ukwehla kwesilinganiso senhliziyo (esingajulile noma engekho).
Ngaphezu kwalokho, ngokusho kwendlela kaFisher, ngayinye imiphumela etholakalayo, kufakwe amaphuzu angu-2, afakwa ngokufingqiwe.
Uma unamaphuzu angu-8-10, asikho isizathu sokukhathazeka. Lezi zinkomba ze-CTG ye-fetus zibhekwa njengesijwayelekile.
Amaphuzu ayi-6-7 akhombisa ukuthi kunezinkinga ezithile okufanele zivele ngokushesha. Owesifazane uzodinga ucwaningo olwengeziwe.
5 futhi amaphuzu ambalwa - lokhu kuyisongo esibi empilweni ye-fetus. Ingane cishe inesifo se- hypoxia (i-oxygen starvation). Ungadinga ukuhlala esibhedlela esiphuthumayo. Futhi kwezinye izimo - ukuzalwa ngaphambi kwesikhathi.
Ingabe i-CTG iyingozi kumntwana?
Abazali abaningi besikhathi esizayo abazethembeli nge-cardiotocography. Kufanele kuthiwe ukuthi ukwesaba okunjalo kuyize ngokuphelele. Lolu cwaningo luhlinzeka ngemininingwane eminingi ewusizo ngaphandle kokulimaza impilo yomama noma isisu.
Futhi kungakhathaliseki ukuthi yini othola ngayo nesifundo sokuqala, ungesabi ngokushesha. Phela, i-CTG ayitholakali. Isithombe esiphelele sesimo se-fetus asikwazi ukunikezwa ngendlela eyodwa. Kubalulekile ukuba nesifundo esibanzi - i-ultrasound, i-doppler, njll.
Futhi ngesikhathi esifanayo, ukubaluleka kwalolu cwaningo kungenakuphikwa. I-CTG inikeza idatha ngesimo sesisu ngesikhathi sokukhulelwa. Kanti futhi, ekusebenzeni komsebenzi, kungenzeka ukunikeza ukuhlolwa okufika ngesikhathi futhi okulungile kokuzalwa nesimo se-fetus.
