Pamberi pekutanga kwokuti amai vanotarisira vanotanga kunzwa sei kutama kunoita mwana, zvakaoma kuti iye achinzwe mumuviri uye anofungidzira mwana ari kutakurwa pasi pemwoyo wake kunze kwake. Manzwiro ehupenyu hunotarisana nemwana anotanga kunyanya kubva panguva yekutanga kwake. O, maitiro akawanda asinganzwisisiki amai vari kutarisana nawo, vanonzwa kudengenyeka kwekutanga kwechecheche yavo, mumimba iri kukura. Pamusangano mukutarisana kwevakadzi, vakadzi vanowira miduku vanorara vane mibvunzo: "Uye paanotanga kufamba? "," Inonzwisisa sei kufamba kwe fetus panguva yekuzvitakura? " "," Anofanira kufamba sei? " "Uye mamwe akawanda akawanda anofadza amai. Kuti tinzwisise zviri nani nyaya ino uye tinzwisise kutama kwe fetus, tinoyeuka matanho makuru ekusimudzirwa kwemwana muchibereko, zvesayenzi zvinonzi zvikamu zve embryogenesis.
Chikwata chokutanga muchibereko chinotanga kuitwa nokukurumidza zvakakwana. Asi kufamba kwemucheche hakugoni kurongeka uye hakunzwisisi, mwana wacho muduku zvokuti kushambira mumamniotic fluid, kazhinji inobata masvingo emuviri uye amai havagoni kunzwa manzwiro awa. Zvisinei, kubva muvhiki yegumi yekuzvitora, mushure mokunge kugumburwa pamadziro echibereko, mwana anogona kutotanga kushandura kutungamira kwekufamba, iyi ndiyo yekutanga kugadzirisa zvinetso. Kubva pavhiki yechitanhatu, anokwanisa kutomesa amniotic fluid, uye iyi ndiyo yakaoma yakafanana nemotokari. Nekuvandudzwa kwenhengo dzenzwi uye nekuvandudza kwavo, mwana anotanga kutarisana nemisvo yevhiki ye16 (kazhinji inowanikwa nenzwi reamai, kushandura mazwi ake.) Pamasvondo gumi nemana mwana anogona kutora. Pamasvondo gumi nemasere anodzika uye asingatomboregi mazamu neminwe yake, anobata uye anobata rwonzi rwakasununguka nemaoko ake, uye paanonzwa nenzwi guru, rinorwadza uye risina kufadza, anofukidza chiso chake. Munguva yemavhiki makumi maviri nemasere kusvika pakuberekwa mwana anowanzogara. Yakanga iri panguva iyi amai vangu vakatanga kunzwa kunzwa kutama kwe fetus. Kazhinji, mukukwirirana kwevakadzi, fetus inofamba mberi pakuzvitora musati mimba, asi, zvechokwadi, mumukadzi wese ane pamuviri aya mazwi anonyanya kuitika.
Iko amai vanonzwa sei kana mwana mucheche achienda kwekutanga? Munhu wose anotsanangura manzwiro aya nenzira dzakasiyana. Vamwe vanozvifananidza nekusvibisa hove, kuputika mavhirifu, kana kuti nekuputika kwemukati. Kune vakadzi vazhinji, nguva idzi muupenyu ndeimwe yezvinofadza uye yakamirira kwenguva refu, nokuti kubva panguva iyoyo amai vanotanga kunzwa mwana wavo nenzira itsva. Pakutanga, kufamba kwakashata uye kusingaoneki kwema fetus nokukurumidza kunorongedzwa uye kwakarongeka. Saka mumwedzi wemwedzi wemashanu-fetus mune imwe nguva yeawa imwe inogona kuita kudengenyeka kwe20-60, kukanganisa uye kutendeuka. Inenge kubva mavhiki makumi maviri nemasere ekuberekwa, fetus inowanzoita kubva kune 10 kusvika ku15 kufamba kweawa, panguva yokurara, dzimwe nguva kusvikira maawa matatu, haisi kufamba. Kubva pamasvondo makumi maviri namasere nemaviri ekuberekwa kwemazuva ekupedzisira basa rakawanda rekuita mwana rinouya rinoratidzwa. Nenguva yekuberekwa kwebasa inoderera, asi simba rekushambadzira kwe fetal rinowedzera. Kubvira pamasvondo makumi maviri nemasere ekuberekwa, zvinokwanisika kuongorora kufamba kwe fetus maererano neuedzo wePearson. Zuva rimwe nerimwe, pamapu chaiwo, nhamba yekutama kunoitwa nevana remangwana inogadziriswa. Tanga kuongorora nhamba yezvakavhiringidzika panguva yakabva 9 am kusvika 9 pm. Nguva yekutama 10 yakanyorwa mutafura. Nhamba yezvakavhiringidzika, zvisingasviki gumi, inogona kuratidza kushayikwa kweokisijeni ye fetus, pane izvo zvikafanira kuonana nachiremba pasina nguva.
Ramangwana amai vanofanira kugara vachimuteerera kufamba kwechecheche. Chiratidzo chekukurumidzira kuguma kwemotokari kwemaawa 12 kana kupfuura. Kuzvimiririra kushandura kufamba kwe fetus, unogona kuburikidza nekuita zvimwe zvekurovedza muviri (zvakanyatsogadzirirwa vakadzi vane pamuviri), kunwa mukaka kana kudya chimwe chinhu chinotapira. Kana basa remuwana rakaderera zvinoshamisa kana zvinopesana, mwana anongoronga chaiyo "discos" mudumbu, amai vakatarisira vanofanira kugara vachitaura nachiremba wavo. Kana paine mwana anopfuura mumwe ari kubuda mudumbu reamai, uye mapatya ari kukura, kufamba kunowedzera uye kunonzwa kwose kwose. Dzimwe nguva kusava nemafungiro emucheche, anogona kutaura pamusoro pekushaya nzara kwehogiji ye fetus. Mune zvikamu zvekutanga zve hypo hypoia, mufambiro wekusadzora unhu hunozivikanwa, hunoonekwa nehuwandu hwahwo hunokurumidza uye huchiwedzera. Zvishoma nezvishoma, kana hypoxia ichifambira mberi, mukana wekutama unowedzera kana kumira. Zvinokonzera hypoxia zvingave zvakasiyana: kushayikwa kwesimbi kusina anemia, kuvapo kwezvirwere zvepfungwa mumudzimai ane pamuviri, kusagadzikana kwepfungwa, zvirwere zve fetus. Kana mukadzi ane pamuviri nekufungidzirwa kwemogiji yekushaya nzara yemucheche, amai vanopiwa chirwere chemoyo, iyo nzira iyo maitiro emwoyo emwana asati aberekwa akanyorwa achishandiswa chinhu chinokosha. . Mumaminitsi 30-60, fetal mwoyo yakanyorwa, uye zvino migumisiro inoongororwa maererano neizvi. Kazhinji, mutambo wemwoyo unosiyana kubva pa12 kusvika ku 160 kurohwa paminiti. Kuwedzera kwe fetal heart rate kusvika kune 170-190 kurohwa ndiko kunowanzoonekwa uye kunoonekwa sekuita kwomwana kune zvinokurudzira kunze. Kana pane zvikanganiso zviduku mumatare eKGT, vakadzi vane pamuviri vanowana chirongwa chakakonzerwa nekuvandudza uteroplacental blood flow, data yeKGT yakanyorwa zuva rega rega. Uyewo pakuwedzera kuongorora basa rakanaka rekupararira kweropa mumidziyo kunobatsira doplerometry. Kutora kufamba kwechirwere chiratidzo chehutano hwake uye rudzi rwechiratidzo chekubata pamuviri nekubudirira, saka kana pane chero mubvunzo we "kushamisa" mafambiro, zvakakosha kuonana neyanyanzvi.
Kutanga kwokutanga kwomwana - izvi hazvirevi chete chiratidzo chemuviri wake uye kukurudzirwa, ihwo hunoyevedza humwe humwe humwe humwe hupenyu huri muhumai huchauya. Uye pakugumisa ndinoda kufarira vose vakadzi vane pamuviri kuti varambe vaine hutano uye vachifara munguva yakadaro inoshamisa uye inonakidza yehupenyu hwavo - nguva yekuzvitakura.
