Kupiwa kwezvibereko kubva kuna amai kusvika pamucheche, pamwe nekuregererwa kwezvigadzirwa zvemagetsi zvinoitwa pamwe nekubatsirwa kwembambo, iyo inobatanidza placenta nemhete yombilical yemucheche.
Maitiro emutsara wembilical
Iko inokosha, kubva pane iyo inonzi umbilical inoenda kumwana: mumusana iyo inoparadzana kubva pakati nepakati pencenta, kunyange zvazvo zvichibvira kumativi akasiyana-kubva kune imwe yerutivi rwayo, kana kuti kusungirirwa kwemukati - mutsara wembilical inoparadzana kubva pamabhanhire anobva pane iyo midziyo inobva ku-placenta yakatambanudza. Iyo yakagadzirwa inopera nemavhiki gumi nemaviri, uye umbilical cord inoshanda kusati kwazvarwa kuberekwa. Kazhinji muvhareji urefu hwembilical cord inobva 40 kusvika 70 cm, kana isingapfuuri 40 cm, inopfupika mumbilical cord , inopfuura 70 cm yakareba.
Ndeipi midziyo yakawanda inofanira kunge yakagadzirirwa?
Kazhinji, tambo yembilical ine mitsara mitatu: mitsetse miviri uye mutezo, pakati payo pane chinhu chakasimba kwazvo, chinodzivirira kutapurika kwevascula mumutsara wembira: vartons jelly. Asi dzimwe nguva midziyo 2 chete inowanikwa mumutsara wembilical, mumakumi mashanu ematambudziko haigadziri chinhu zvachose uye fetus inowanzogara yakawanda. Asi, kana musungo wembilical uine midziyo miviri chete, zvakakosha kuongorora itsvo dze fetus, sezvo izvi zvingava chiratidzo chekuzvarwa kwemafiro etsvo, kana kuti, chiratidzo chekushayikwa kweimwe itsvo.
Node pamutsara wembilical - chii ichocho?
Mukati yekukura kwayo, umbilical arteri inokura uye inoshandura helically yakakomberedza mutsva, uye mushure mokunge umbilical yose inoshanduka mumhepo. Nekukurumidza kukurumidza kwemidziyo iyi, kuumbwa kwemakumbo kubva mumidziyo kunobvira, uye ne varicose mitsemvu ye umbilical vein, node-yakafanana ne thickenings (nheyo dzenhema dzemuviri wembilical). Ne node dzenhema, ropa rinoyerera mumutsara wembilical harina kunaka.
Ichokwadi kuti node dzechokwadi dzemudumbu dzinoumbwa panguva yekufamba kwemwana uye munguva yebasa, asi dzinowanzoita kuti pave nemigumisiro yakaipa, asi mumatangiro ekutanga ekudzivirira, musimboti wakaoma unogona kuita kuti atrophy yevarton jelly inokonzera kukanganisa kweropa mumutsara.
Inotyisa sei tambo ine tambo yombilical?
Munguva yekuongorora kwe ultrasound muhafu yechipiri yekuzvitakura, kazhinji protocol inoratidzira kuvapo kwembambo yembilical pedyo nehuro. Asi, kazhinji zvakakomberedza chiso chemucheche, pane kazhinji kambo dzembilical uye zvakakosha kutarisa kana chishongo chakadaro chiri pamutsipa. Izvi hazviwanzovimbwa nguva dzose mune chiitiko chekudzidza, asi chinonyatsooneka muDoppler. Asi tambo ine ruvara rwembilical kazhinji haitungamiri kumigumisiro yakaipa, kana pasina zvimwe zvinetso pakuberekwa, uye haisi kupesana kwekuzvarwa kwekuzvarwa. Asi mharidzo yaro kana kupera kwembambo yembilical kubva kumubhedha wokuberekwa inonyanya kuipa kumucheche, sezvo kuwedzerwa kwemutilical pakati pekuberekwa kwemvura uye fetus kunotungamirira ku-asphyxia uye kufa kwekufa mu 90% emhosva.
