Inyanga yesikhombisa yokukhulelwa iphela: kusukela emavikini angu-27 iqala okwesithathu - i-trimester yokugcina yokukhulelwa . Zonke izitho zengane sezivele zakhiwe, kodwa ziqhubeke ukuthuthukisa nokulungiselela impilo ngaphandle kwesisu somama. Ubuchopho buyaqhubeka nokuthuthukisa.
Isisindo se-fetus emavikini angu-27 silinganiselwa ku-kilogram: singaba kusuka ku-900 g ukuya kuma-1300 g (isilinganiso). Ubukhulu be-fetus emavikini angu-27 (i-fetometry ye-fetus ngamasonto angu-27) angashintsha ngokuya ngezici zokuthuthukiswa kwengane. Emasontweni angu-27 wokubeletha, usayizi wesisu nesifo se-ultrasound (i-fetus uzi amaviki angu-27) ngu-34-37 cm, kusukela komqhele kuya komsila 24-26 cm.
Ubukhulu obuphakathi kwekhanda lesisu, elizokwenza umqondo wokuthi ingane ibheka kanjani, zimi kanje:
- usayizi we-biparietal (ama-bppr amaviki angu-27) ngu-69 (mm);
- Umjikelezo we-skull ngu-215 (mm);
- indawo ye-skull ingu-3675 (mm).
Cishe ngesonto lama-27 lokukhulelwa i-retina yenziwe ngokuphelele, amajwabu amehlo avulekile futhi i-eyelashes ikhula. Umsebenzi ozithandayo we-fetus unamaviki angama-26-27 - ophuza umunwe, ohlala othanda emva kokuzalwa.
Amaphaphu omntwana aqhubeka ethuthuka ngenkuthalo. Ukuphefumula kwesisu kuhlinzekwa yi-placenta, lapho imithwalo ye-arterium embilical iguqula igesi phakathi kwegazi le-fetus negazi lomama. Ukunyakaza kokuphefumula kwe-fetus kusiza ekuthuthukiseni imisipha yokuphefumula, ukuthuthukiswa kwamaphaphu nokujikeleza kwegazi kwe-fetus, ukwandisa ukugeleza kwegazi enhliziyweni ngemuva kokucindezeleka okungesihle esifubeni se-fetus.
Owesifazane ngeviki lama-27 lokukhulelwa
Umama wesikhathi esizayo kakade, kakade, kunzima ukuhamba, ukuhlukunyezwa kwenhliziyo nokubuhlungu esifubeni, ukuthuthumela okucasulayo. Ngenxa yokwanda kwesisu, isikhungo sokuguqulwa kwamandla adonsela phansi, ukuguqulwa kokumiswa, emuva kugoba phambili, okubangela ubuhlungu emhlane ophansi. Odokotela batusa ukuthi abesifazane abakhulelwe abaphonseli umlenze emlenzeni wabo, okungaholela emithanjeni ye-varicose, ungaphenduli, njengoba lokhu kungaholela entambo yokubopha intambo ngensimbi yomzimba , ngakho-ke uma kunesidingo, kudingekile ukuba uqhubekele kunokugxila. Futhi ungasincoma ukuthi uqambe amanga isikhathi eside ngemuva, ngoba lesi sibeletho sicindezela ngamandla emithanjeni yegazi, engabangela ubuthakathaka obuqinile. Ababhemayo kudingeka bayeke ukubhema, futhi abangewona abokubhema abangekho ezindaweni ezigcwele ukubhema, ngoba ingane ibhekene nokubhema nokuvuselela ukubhema ugwayi.
Abesifazane abaningi, ikakhulukazi labo abathintekayo kakhulu ngesibalo sabo, bakhungathekile kakhulu ngokwanda kwevolumu kanye nesisindo, okubonakala ngokucacile ku-trimester yesithathu. Abaningi abanomama abalindayo banenkinga ngezingubo, abakwazi ukukhuphukela emajayini abo abathandayo futhi badinga ukuthenga amabhulukwe namabhantshi akhethekile abesifazane abakhulelwe abanomzimba obanzi obukhulu esikhwameni ukuze bangacindezeli ingane. Izindebe zivuvukala, udinga ukugqoka izicathulo kuphela ukhululekile, ngaphandle kwesithende, le nkinga inzima ikakhulukazi ngenkathi yasebusika. Naphezu kokuzuza kwesisindo, ukudla akukwazi ukunamathela futhi ungakwazi ukuzikhawulela ekudleni, udinga ukunciphisa ukusetshenziswa kwama-carbohydrate, futhi ukudla kufanele kube okunengqondo futhi okuvamile. Ngendlela yokubonakala kwengane, isifuba somama esizayo sishintsha, kuba ngaphezulu
Izithelo emavikini angu-27
I-fetus emavikini angu-27 isivele ibukeka njengengane esanda kuzalwa, umzimba wayo ulinganiselwe, ubuso bubumbene futhi yena, ukuqonda lapho ukukhanya kuvule amehlo akhe bese kuguqula ikhanda lakhe. Ingane iphenduka njalo, naphezu kokwanda kwesisindo somzimba nokuphakama. Ukudumala kunamaphesenti angama-140 ngomzuzu, ukuphefumula cishe izikhathi ezingu-40 ngomzuzu. Odokotela bathi uma kwenzeka ngesikhathi sokubeletha, ingane yakho isinda emasontweni angu-27-28 kuma-85% amacala, evame ukuthuthukisa nokubamba iqhaza ekuthuthukiseni nasekukhuleni kwabo ontanga.
