Thaum cev xeeb tub heev, tus poj niam cev xeeb tub tuaj yeem hnov ​​​​qab sai sai ntawm kev siv zog me ntsis. Raws li qhov tshwm sim ntawm ntau yam kev hloov pauv ntawm lub cev tsim nyog los ua kom tau raws li qhov xav tau ntawm tus menyuam, qhov ua tsis taus pa thaum cev xeeb tub yog qhov qub.

Thaum cev xeeb tub, ntau yam kev hloov pauv yuav tsum tau ua kom tau raws li qhov xav tau ntawm metabolic ntawm leej niam thiab tus menyuam hauv plab. Txuas ncaj qha rau cov tshuaj hormones cev xeeb tub, qee qhov kev hloov pauv ntawm lub cev ua rau ua tsis taus pa hauv niam-rau-ua, ntev ua ntej lub tsev menyuam compresses nws lub diaphragm.

Txhawm rau ua kom tau raws li cov pa oxygen xav tau ntawm cov placenta thiab tus menyuam hauv plab kwv yees li ntawm 20 txog 30%, muaj qhov tseeb tag nrho ntawm kev ua haujlwm ntawm lub plawv thiab ua pa. Cov ntshav ntim nce ntxiv (hypervolemia) thiab lub plawv tso zis nce li ntawm 30 mus rau 50%, ua rau hauv cov pa ua pa nce ntxiv hauv cov ntshav pulmonary thiab oxygen uptake ib feeb. Lub zog secretion ntawm progesterone ua rau muaj kev nce hauv cov pa ua pa, ua rau hyperventilation. Qhov ua pa ua pa nce ntxiv thiab tuaj yeem ncav cuag 16 ua pa ib feeb, ua rau muaj kev xav tias ua pa luv ntawm kev tawm dag zog, lossis txawm tias so. Nws kwv yees tias ib ntawm ob tus poj niam cev xeeb tub muaj qhov ua tsis taus pa (1).

Los ntawm 10-12 lub lis piam, txoj kev ua pa ntawm leej niam-rau-yuav hloov pauv hloov pauv mus rau cov kev hloov pauv txawv no, thiab mus rau lub neej yav tom ntej ntawm lub tsev menyuam: qhov qis dua qhov dav, theem ntawm lub diaphragm nce, txoj kab uas hla ntawm lub tsev menyuam. thorax nce, cov nqaij ntshiv plab yuav tsis toned, tsob ntoo ua pa yuav congested.

Hais lus nruj me ntsis, tus me nyuam tsis ua pa hauv utero; nws tsuas yuav ua li ntawd thaum yug los. Thaum cev xeeb tub, tus placenta plays lub luag haujlwm ntawm "fetal ntsws": nws nqa oxygen mus rau tus menyuam hauv plab thiab tshem tawm cov pa roj carbon dioxide fetal.

Kev ntxhov siab hauv fetal, piv txwv li tus me nyuam tsis muaj oxygenation (anoxia), tsis cuam tshuam rau leej niam qhov ua tsis taus pa. Nws tshwm sim thaum lub sij hawm intrauterine loj hlob retardation (IUGR) kuaj pom ntawm ultrasound, thiab muaj peev xwm muaj ntau yam keeb kwm: placental pathology, pathology nyob rau hauv leej niam (plam teeb meem, hematology, gestational diabetes, haus luam yeeb, thiab lwm yam), fetal malformation, kab mob.

Raws li qhov nyiam ua tsis taus pa thaum cev xeeb tub yog physiological, nws nyuaj rau zam. Txawm li cas los xij, tus niam yav tom ntej yuav tsum tau saib xyuas, tshwj xeeb tshaj yog thaum kawg ntawm cev xeeb tub, los ntawm kev txwv kev siv lub cev.

Nyob rau hauv qhov kev tshwm sim ntawm ib qho kev hnov ​​​​tsw, nws muaj peev xwm ua tau qhov kev tawm dag zog no kom "dawb" lub tawb tawb: pw ntawm koj sab nraub qaum nrog koj ob txhais ceg khoov, nqus pa thaum tsa koj txhais tes saum koj lub taub hau ces exhale thaum nqa koj txhais tes rov qab. nrog lub cev. Rov ua dua ob peb ua pa qeeb (2).

Kev ua pa ua pa, kev ua haujlwm sophrology, yoga ua ntej yug menyuam tuaj yeem pab cov niam uas muaj kev cia siab los txwv qhov kev xav ntawm kev ua tsis taus pa uas cov khoom puas siab puas ntsws tuaj yeem ua rau pom.

Raws li lub lis piam ntawm cev xeeb tub, cov plab hnyuv siab raum tau siv ntau dua thiab tus menyuam xav tau oxygen ntau dua. Lub cev ntawm leej niam-rau-yuav tsim cov pa roj carbon dioxide ntau dua, thiab nws yuav tsum tshem tawm ntawm tus menyuam. Yog li ntawd lub plawv thiab lub ntsws ua haujlwm hnyav dua.

Thaum kawg ntawm cev xeeb tub, ib qho khoom siv tau ntxiv thiab ua rau muaj kev pheej hmoo ntawm kev ua tsis taus pa los ntawm kev txo qhov loj ntawm cov tav tawb. Raws li lub tsev menyuam nyem lub diaphragm ntau thiab ntau, lub ntsws muaj chav tsawg dua rau inflate thiab lub ntsws muaj peev xwm txo. Qhov hnyav nce kuj tuaj yeem ua rau muaj kev xav hnyav thiab ua rau ua pa luv, tshwj xeeb tshaj yog thaum lub zog (nce stairs, taug kev, thiab lwm yam).

Hlau deficiency anemia (vim tsis muaj hlau) tuaj yeem ua rau ua pa luv ntawm kev tawm dag zog, thiab qee zaum txawm tias so.

Hauv kev sib cais, ua pa luv tsis yog lub cim ceeb toom thiab yuav tsum tsis txhob ua rau muaj kev txhawj xeeb thaum cev xeeb tub.

Txawm li cas los xij, yog tias nws tshwm sim tam sim ntawd, yog tias nws cuam tshuam nrog kev mob ntawm cov nyuj hauv qhov tshwj xeeb, nws raug nquahu kom sab laj kom txiav txim siab txog kev pheej hmoo ntawm phlebitis.

Thaum kawg ntawm cev xeeb tub, yog tias qhov ua tsis taus pa no nrog kiv taub hau, mob taub hau, edema, palpitations, mob plab, pom kev cuam tshuam (qhov hnov ​​​​ntawm yoov nyob rau hauv pem hauv ntej ntawm lub qhov muag), palpitations, kev sab laj xwm txheej ceev yuav tsum tau txhawm rau txhawm rau kuaj pom cev xeeb tub. -induced hypertension, uas tuaj yeem loj heev thaum kawg ntawm cev xeeb tub.
