Isikhathi sokubeletha owesifazane singamaviki angu-38 kusukela ngesikhathi sokukhulelwa. Kulaba besifazane abaningi, ukukhulelwa kuthatha izinsuku ezingu-266. Kodwa akunakwenzeka ukubala usuku lokuzalwa okuzayo kuze kube usuku olulandelayo. Okuningi kuxhomeke esihlokweni se-hormonal sowesifazane, esihambisana nezifo zomama nesisu, ubulili nesisindo somntwana ongakazalwa, njll. Kodwa emva kwamasonto angu-37 okukhulelwa umntwana ulungele impilo yokuzimela (isikhathi esigcwele). Emva kwalesi sikhathi ingane ezalwa iyasebenza ngokuphelele.
Kodwa ingane emva kwamasonto angu-42 wokukhulelwa kubhekwa ukuhlupheka , kanti umsebenzi ungaphathelene nezinkinga ezinkulu ezinganeni. Ngakho-ke, leli gama lokukhulelwa kubalulekile ukwazi kangako usuku olulindelekile lokuzalwa, kodwa kunalokho ukwazi ukuthi ukubelethwa kowesifazane kuzobhekwa njengokujwayelekile, kanye nengane egcwele.
I-Term of pregnancy obstetric and fetal - umehluko
Isikhathi sokukhulelwa sokukhulelwa singamaviki angama-40, kanti isikhathi sokubeletha ngamabryonic singama-38. Umehluko yizinsuku ezingu-12-14. Ukukhulelwa okuphazamisayo kuqala ngosuku lokuqala lwenyanga eledlule. Isikhathi sobriyoni siqala kusukela ngosuku lokukhulelwa (kusukela ngosuku lokuvuthwa, okuvame ukuza ngosuku lweshumi nanhlanu kusukela ekuqaleni kwenyanga kanye noma okungenani izinsuku ezingu-4).
Indlela yokubala ukukhulelwa kwe-obstetric?
Ukubeletha okuphazamisayo nokukhulelwa kwangempela (embryonic) ukukhulelwa kuyahluka kwamasonto amabili. Ngokwenza njalo, isikhathi se-embryonic singacatshangwa futhi sinqunyelwe ukubala kuphela isithiyo sokuzivikela. Uma owesifazane engazi usuku kuphela lokuqala kwesimiso sokugcina, kodwa futhi usuku lokukhulelwa, imigqa yokukhulelwa i-embryonic inembile kakhulu. Isikhathi sokubeletha esinqunyiwe sithatha izinsuku ezingu-280 kusukela ngosuku lokuqala lwenyanga eledlule. Ngokusho kwemiphumela ye-ultrasound, ngokusho kwamatafula, kuqinisekiswa ukuthi le-fetus ihambisana ne-obstetric, kodwa hhayi embryonic, isisu.
Ngingakwazi yini ukubala usuku lokuzalwa komugqa wokuvimbela?
Indlela elula yokubala usuku olulindelekile lokuzalwa ingacatshangwa okulandelayo: kusukela ngosuku lokugcina lwenyanga yokugcina yengeze izinsuku ezingu-280 (ifomu likaKeller). Kodwa-ke, ngokusemthethweni kunzima futhi usuku olwenzekayo lokubeletha lubekwe ngezindlela ezimbili ezifanayo.
- Ngosuku lokuqala lwenyanga yokugcina yenyanga, izinyanga ezingu-9 nezinsuku eziyisikhombisa zengeziwe.
- Kusukela ngosuku lokuqala lwenyanga eledlule, izinyanga ezintathu zithathwe futhi zengeziwe izinsuku eziyisikhombisa.
Amaviki kusukela ngosuku lokuqala lokugcina esikhathini. Ukuze kube lula udokotela, amaviki angu-40 namanje ahlukaniswe ngamagama amathathu. I-trimester engu-1 ihlanganisa amasonto angu-1-14 okukhulelwa, ama-2 trimester - amasonto angu-16-28, no-3 trimester - kusuka ku-29 kuya ku-40.
Isisu sokuzibophezela kanye nenkathi ye-ultrasound
Akulungile ukuthi ucabange ukuthi i-ultrasound inqunywe yisisu se-obstetric noma se-embryonic. Kunalokho, ngokuphambene nalokho, ngokusho kwamatafula akhethekile, lapho ubukhulu bomntwana obusayizi obuningi buyenzelwe khona amasonto okukhulelwa okubalulekile, kunqume ukuthi ukuhambisana nokukhulelwa kwabo kunzima. Ngokuvamile ubukhulu be-fetus buhambisana nenkathi ye-obstetric kanye nokunciphisa isonto elilodwa: i-fetus iqala ngokujwayelekile. Uma igama le-ultrasound lingaphansi kwe-obstetric, lokhu akusho ukuthi i-obstetric term ibalwa ngokungalungile, kodwa into ethile ivimbela ukuthuthukiswa okuvamile kwe-fetus. Izimbangela eziyinhloko zokuphuza ukukhula kwe-intrauterine yizi:
- ukugula komama;
- ukwephulwa komsebenzi ovamile we-placenta;
- ukukhulelwa okuningi;
- ukungafani kwe-chromosomal ye-fetus;
- ukungena kwe-intrauterine;
- imikhuba emibi kamama;
- ukudla okunomsoco, njll.
Uma igama le-ultrasound liyinkimbinkimbi, khona-ke ngokuvamile ngokuvamile imbangela iyakuba yisisindo esikhulu somntwana ongakazalwa (ngenxa yesifo, isifo sikashukela, ukudla ngokweqile umama ngesikhathi sokukhulelwa).
Kungenzeka ukuthi usuku lokuya esikhathini sokugcina lunikezwe owesifazane ngokungalungile futhi uma ekhumbula usuku lokukhulelwa , kungcono ukubala inkathi ye-obstetric ngokusebenzisa umbryonic, enezela emavikini amabili okugcina.
