Biomechanism kuzvarwa muna marudzi akasiyana previa

Biomechanism kuzvara - wose akagadzirwa zvakasiyana kufamba, izvo kunoita achipfuura kuberekwa Canal vanamai muchero. kufamba izvi zvine chokuita zvakananga sechivako munhukadzi chiuno. Ivo vavete flexion / kuwedzera musoro mwana, zviri zvayaitenderera paguyo kumativi akabatana, asi lateral declination fetus musoro uye zvakavamba kuchinja masangano zvainanga mberi kwayo pamwe pakuberekwa Canal.

kufamba izvi zvose Anopiwa ukuru uye Maumbirwe chiuno vakadzi, kuvapo Líquido mvura yakakwana kwazvo syrovidnoy girisi, izvo akafukidza muviri wemwana, izvo zvinoderedza kukweshera uyewo ukuru uye Maumbirwe fetus musoro. Mukuwedzera, hurukuro inopiwa biomechanism uterine basa, zvakawanda chaizvo, sunga ayo. Izvi zvinoitawo kuti translational kufamba nokuda kusimudzira fetus kubva rwaamai pakuberekwa Canal. Nechimwezve chinhu chinowedzera rutapudzo yacho dumbu, ndiye ayo nemarunda. Panyaya iyi, rwakapoteredza nemarunda sungisa uterine pasi, mberi, uye sacrouterine - vazvichengete, zvomutadzisa rakarasika, uye kugadzirisa pamusoro pechiso sacrum.

Biomechanism kuberekwa ari musoro fetus mharidzo (occipital) inoumbwa zvinotevera zvinhu: vachikotama musoro uye dzinza wayo zvishoma nezvishoma vachipinda pelvic mhango. Kana vakafugama musoro iri pakutsvaga kutungamirira pfungwa - Small fontanelle, riri pedyo chiuno the wired mutsetse. Ndiwo uyu pfungwa uye pane rokutanga dzokubereka mutswe. The chirebvu ari mudumbu panguva imwecheteyo akazvipira chipfuva. Pakutanga musoro anochinja configuration wayo. Uyezve, kana uchifamba kubva paupamhi kune nhete chikamu pelvic unoita nevapanduki. Pashure iyo munhu inoendeswa sacrum uye seri musoro symphysis. Uye pakupedzisira pane kuwedzera musoro wayo mbudo kubva ndege yacho chiuno - anoberekwa ari pahuma, chiso uye chirebvu pakupedzisira. Pashure kuberekwa musoro anotora nzvimbo yaro yepakutanga. Uyezve kuberekwa pamafudzi uye anouya kudzingwa zvakakwana azvarwa.

Biomechanism vashande breech mharidzo anosanganisirawo rotational uye translational kuchiva, asi muchiitiko chino ari mudumbu ichipfuura kuberekwa Canal chiuno mberi. Kana ichi nderei inotungamirira mezhvertilnaya gluteal mutsetse. Pane zvinotevera pfungwa vanoumba biomechanism genera: kuti magaro vari akaiswa munzvimbo chiuno uye kutama payo, fetus nomuzongoza anoita lateral vachipfugama, pashure zvadonherwa mutumbi nepfudzi nebhanhire. Vakafugama fetus musoro wayo yomukati chijana kunoitika substantially panguva imwe chete. Musoro anoberekwa musana chinzvimbo.

Biomechanism kuberekwa Foot praevia akafanana kuchengetwa ari breech. Kazhinji, pashure kuerera Líquido mvura uye kunyange rushoma Kuziviswa kwemashoko cervix previa gumbo anogona kudzikiswa kana kunyange kuwira kunze nyinyo. Izvi zvinoomesa zvikuru uye rinononotsa kufambira mberi basa. Kamwe chete cervix iri zvakazara aratidzwe, chete seri gumbo kuoneka magaro uye zvichingodaro biomechanisms kune pamusoro genera.

Sezvinogona kuoneka, biomechanism dzinongoitika kuzvara kunobva nezvenzvimbo ine michero, uye kubva achitandadza pakugovera waya.
