Uhu hwenhengo yepamusoro inokosha zvikuru yehutano hwekuita gestation, iyo inotarirwa chero nguva nguva chete ne ultrasound. Kuti unzwisise kukosha kwemashoko aya, unofanirwa kuziva chinangwa chechirongwa uye chimiro chechimiro chepentecenta kwemavhiki.
Basa rekanguva "nzvimbo yevana" rinokosha zvikuru uye rinokosha. Iyo placenta panguva yekuzvitakura inopa mwana muchizvaro nezvinhu zvose zvinodiwa, oksijeni, inoshanda sechipingamupinyi pakati pake nemhando dzakasiyana dzezvirwere uye mabhakitiriya. Inobva kuhupamhi hwe-placenta mukudzivirira uye inotarisana nekugadzirwa kwechimiro chechi fetus mudumbu raamai.
Norm weupfumi wepentecenta
Nzira yekugadziridzwa kwechigadziko chinogadziriswa inogona kuteverwa chete nekubatsirwa nemuchina we ultrasound. Iko kune zvidimbu zvakasiyana zvekukura kweparcenta uye pano ivo ndevamwe:
- Zero, iyo iri mumakiromita kusvika kumakumi maviri nemavhiki ekuberekwa;
- chiyero chechipiri chinowanikwa pedyo nevhiki 32 yekutakura;
- dhigirii yechitatu inoratidzwa nehupamhi hwepascenta 36 mm - 29 cm uye inoonekwa nevhiki ye37;
- yechina, uye danho rekupedzisira rekubereka kwepentecenta rinogona kuitika apo fetus inopera.
Kukurukurirana kwehutano hwepentecenta uye nguva yekutenda
Nzira yekugadziridzwa kwechirongwa chepakisi inowedzera kukurumidza uye inorega kuenderana nekuita nguva yekuita gumbo muitiko apo mukadzi ane pamuviri anoramba achishandisa zvinodhaka, doro kana nicotine, uyewo kana pane zvirwere zvinotapukira. Iko kunofanira kunzwisiswa kuti mukugadzirwa kwekwegura iyo placenta inotanga kuderedza kushanda kwayo. Izvi zvakazara nehogijini yekushaya nzara kwemwana, kukura kwayo kusingagutsikani, kushayikwa kwezvibereko uye kuyerwa kunorema. Chikonzero chakaipa kwazvo chekushaikwa kwemaitiro akaenzana epa placenta ndiyo kufa kwemukati kwevana kana kutanga nguva isati yapera.
Kuwedzera mune zvakasara zvehupamhi hwepentecenta nemavhiki
Izvi zvinoshanda sechiratidzo chekuvapo kwechimwe chinhu munguva yekudzivirira uye inoguma nechirwere chepachirwere, chirwere cheshuga, chirwere cheshuga, gestosis kana kukakavara pakati peamai nevana. Kuvapo kwezvinhu izvi ndicho chikonzero chekuwedzera kunyanya kubva kune vashandi vekukurukurirana kwevakadzi. Maitiro ehupamhi yepentecenta kwemavhiki zvakasiyana kwazvo uye anofanira kuonekwa neanotungamirira gynecologist-obstetrician.
Zvimwe zviratidzo zvekukura kwemuviri
Kubva pane data yakagadzirwa ne ultrasound, unogona kuongorora mufananidzo wehupenyu hwemwana, hunotarisana zvakananga nemamiriro ezvinhu eparcenta. Saka:
- Uturu hwepentecenta pamasvondo makumi maviri nemasere hunenge 17 mm uye hune sarudzo yunifomu. Chiremba anoongorora nzvimbo yenhengo uye kureba kwayo kubva pamadziro emuviri.
- Utsi hwepentecenta pamasvondo makumi maviri nemashanu huri kuramba huchikura uye hunogona kuenzana kusvika kusvika 22 mm.
- Pamasvondo makumi maviri nemaviri, kubwinya kwepentecenta kutotanga kusvika kusvika 25 -26 mm.
- Utsi hwepentecenta pamasvondo makumi matatu hauna kuwedzerwa uye nzira yekuwedzera kwayo kuderera uye kuunganidza kaccium inotanga.
- Iko kufanana kwehutanda hwepa placenta pamasvondo makumi matatu nemakore makumi matatu nemasere kusvika masikati.
- Kukura kwepentecenta pamasvondo makumi matatu nematatu kunotanga kuderera nekuda kwekubuda ropa nekuderedza kushandiswa kwemagetsi, sezvo mwana akagadzirira hupenyu kunze kwechizvaro cheamai. Ichi chiratidzo chinogona kuva 34-35 cm.
Ichokwadi kuti iyo placenta yakajairika, haifaniri kubvumira mukadzi kuti asatarise nzvimbo yake. Anosungirwa kuti arambe achinyatsoona nezvehutano uye anoita zvose zvinodiwa kuti aite mwana akazara.
