Indlela yokunquma ukuqala kokubeletha inja?

I-Ultrasonography ingasiza ekunqumeni inani lezinsuku zokubeletha ngokulinganisa ubukhulu bekhanda le-biparietal le-fetus nokusebenzisa ifomula ekhethekile yokulinganisa ezinjeni ezinosayizi abahlukene.

Kusukela osukwini lwama-42 lokukhulelwa, uhlaka lwamathambo e-fetus lubonakala kuma-radiographs, kusukela ngosuku lwama-45 kuya ku-49 amathambo ogebhezi abonakala ngeso lengqondo, kusukela ngosuku lwama-57 kuya ku-59 - amathambo e-pelvis, kusukela ngosuku lwama-58 kuya ku-63 - amazinyo.

Ezinsukwini ezi-2 kuya kwezingu-7 ngaphambi kokubeletha, izinja zingase ziqale ukukhombisa izimpawu zokujabula, ukungahlaliseki, ukuzalanisa, ukuchama okukhulayo kanye nokuthuthumela, kanye nokuncipha kwesifiso sokudla.

Lokhu kungenxa yokwanda kancane kancane kokufinyela kwesibeletho. Ngosuku lokubeletha, ukudla kungase kungabi khona ngokuphelele.

Ukukhula kwebele kuqala engxenyeni yesibili yokukhulelwa. Ukuncelisa kwamanye ama-bitches kubonakala kusukela osukwini lwama-40 lokukhulelwa, kwezinye ngaphambi nje kokubeletha, phakathi kwazo noma ngokushesha ngemva kwalokho.

Ukwanda kokuxineka kwe-hormone i-relaxin egazini kuholela ekwandeni nasekuthambeni kwe-loop (izinsuku eziyi-0-2 ngaphambi kokubeletha), ukuphumula komlomo wesibeletho futhi, ngenxa yalokho, ukuhlukaniswa kwepulaki ye-mucous (izinsuku eziyi-0-7). ngaphambi kokulethwa).

Ukwehla kwezinga lokushisa lomzimba ngaphambi kokubeletha kuyinkomba enokwethenjelwa yokuqala kokubeletha ezinjeni, okubonisa ukwehla ngokushesha kwamazinga egazi e-hormone progesterone ngaphansi kwe-1 ng/mL, i-hormone ye-thermogenic egcina ukukhulelwa. Izinga lokushisa lomzimba lehla kakhulu (lifinyelele cishe ku-36,7-37,7 degrees).

Kufanele wazi ukuthi ngemva kokuwa, izinga lokushisa lizokhuphuka kancane (kuze kufike ku-37,2 degrees) futhi lizogcinwa kuso sonke isigaba sokuqala sokuzala. Ngalesi sikhathi, amahora angu-8-24 asele ngaphambi kokuvela komdlwane wokuqala.

Kunconywa ukuqala ukulinganisa izinga lokushisa le-rectal kusukela ngosuku lwama-54-55 lokukhulelwa izikhathi ezingu-1-2 ngosuku ngesikhathi esifanayo.

Ukwehla kancane kokushisa komzimba kungase kwenzeke ngesonto lokugcina lokukhulelwa, njengoba izinga le-progesterone egazini liyancipha kancane kancane. Nokho, kwezinye izinja, akunakwenzeka ukulungisa umzuzu wokwehla kwezinga lokushisa ngale ndlela.

Ukuqhekeka kwesaka lokuqala le-amniotic, ukuphuma kokukhishwa okuphuzi-okuluhlaza (amanzi) ezithweni zangasese zangaphandle kubonisa ukuhlukaniswa kwe-placenta kanye nokuqala kwesigaba sesibili sokubeletha (isigaba sokuzama - ukuxoshwa kombungu) ; futhi ngaphambi kokuvela komdlwane wokuqala, amahora angu-1-2 asele.
