Kubadwa Biomechanism mu osiyanasiyana previa

Biomechanism pobereka - lonse ya kayendedwe zosiyanasiyana umatipanga kudutsa kubadwa ngalande amayi zipatso. kayendedwe ameneŵa zokhudzana ndi kapangidwe ka mafupa a chiuno wamkazi. Pogona mu flexion / kutambasuka kwa mutu wa mwana, izo zimayenda mozungulira olamulira, ndi lateral declination yoopsa mutu ndi pendulum kayendedwe umalimbana kupititsa patsogolo pamodzi ndi ngalande kubadwa.

magulu awa onse operekedwa ndi kukula ndi mawonekedwe a mafupa a chiuno akazi, pamaso pa madzimadzi amniotic mu okwanira kuchuluka syrovidnoy mafuta, amene anaphimba thupi mwana ayeziyo komanso kukula ndi mawonekedwe a mutu yoopsa. Komanso yobereka zilipo ntchito biomechanism uterine, yeniyeni, contractions ake. Izi amalenga kayendedwe translational kwa Kukwezeleza yoopsa ku ngalande kubadwa akuchikazi. Mfundo ina imene kumathandiza kuchepetsa a chiberekero, ndi Mitsemphayi ake. Mu nkhani iyi, Mitsemphayi wozungulira kumangitsa pansi uterine, kutsogolo ndi sacrouterine - kugwira, kuteteza yosokera, ndi kukonza padziko sacrum lapansi.

Biomechanism kubadwa pa mutu yoopsa ulaliki (occipital) Amakhala ndi zinthu zotsatirazi: kupinda mutu ndi mbadwa zake pang'onopang'ono kuti patsekeke m'chiuno. Pamene kupinda mutu anatsimikiza ndi mfundo kutsogolera - Small fontanelle, amene ali pafupi ndi mafupa a chiuno cha basi anatumizanso lamya mzere. Ndi mfundo imeneyi ndipo pali woyamba wa kudula maliseche. The chibwano cha mwana wosabadwayo nthawi yomweyo anachita kuti chifuwa. Kumayambiriro kwa mutu azisinthidwanso kasinthidwe ake. Komanso, pamene amayenda chachikulu kwa gawo yopapatiza a m'chiuno cha wachita kulanda boma. Kenako munthu walangizidwa pa sacrum ndi kumbuyo kwa mutu kuti symphysis lapansi. Ndipo potsiriza pali kutambasuka kwa mutu ndi kuchoka ake ku ndege ya mafupa a chiuno ndi - wabadwa mphumi, nkhope ndi chibwano lomaliza. Atabadwa mutu amatenga malo ake apachiyambi. Komanso anabadwa mapewa ndipo wafika athamangitsidwe wathunthu wa mwana wosabadwayo.

Biomechanism ntchito ndi breech ulaliki mulinso rotational ndi translational mwaulesi, koma mu nkhani iyi wosabadwa umadutsa mafupa a chiuno kubadwa ngalande patsogolo. Pamene izi ndi zofunika kalozera mezhvertilnaya gluteal mzere. Pali mfundo zotsatirazi apanga biomechanism genera: ndi matako ndi anaikapo mu mafupa a chiuno ndi kusuntha adalira yoopsa msana zimapangitsa lateral kupinda, kenako pakubwera torso ndi phewa lamba. Kupinda yoopsa mutu ndi kukhota ake mkati amapezeka zayamba imodzi. mutu wabadwa mu malo wopindidwa.

Biomechanism kubadwa Kumapazi praevia ndi ofanana ndi amene asunga mwa breech lapansi. Nthawi zambiri, pambuyo kumaliseche kwa amniotic madzimadzi ndi ngakhale tsankho Kuwulura wa khomo pachibelekeropo previa mwendo akhoza adatchithisira kapena kugwa amatulukira kudzera ku nyini. Izi complicates kwambiri ndi akuzengereza patsogolo ntchito. Kamodzi khomo pachibelekeropo ndi kuwululidwa kwathunthu, kumbuyo mwendo kuoneka matako ndi zina zotero biomechanisms kuti genera pamwambapa.

Monga mmene taonera, biomechanism zachilengedwe pobereka zimadalira malo amene ali zipatso, ndi kufika kuwayika waya.
