Ama-anomali wezabasebenzi abizwa ngokuba ukuphulwa kwintsebenzo enkonzweni yesibindi. Oku kukhokelela ekuphambukeni kwiindlela zokuvulwa komlomo wesibeleko kunye nokuhamba kwe-fetus ngokusebenzisa isalathiso sokuzalwa. Izizathu zolu hlobo lentsholongwane lungaba utshintsho kwizalathisi ezinjengelizwi lesibindi, ubude, ixesha, ukunyaniseka, ubude, isantya kunye nokulungelelaniswa kwezicatshulwa.
Ukunyanzeliswa kweziqendu. Ixesha lokulungiselela, xa i-precursors of labor are revealed, ngokuqhelekileyo idlulela kwii-preliminals, ilandelwa ngokuzalwa. Ngokuqhelekileyo iziganeko zokugqibela zingaphelanga iiyure ezingama-6 kwaye ngokukhawuleza ziya kulwaphulo oluqhelekileyo. Kwimeko yokwephulwa kwimiqathango yokuqala, kukho iimpawu ezithile. Ziyinto engavumelekanga kwixesha elide, ubuninzi kunye nobude beentlungu ezidityanisiweyo kwisisu esisezantsi, kufuphi nomlenze kunye ne-sacrum. Intlungu enjalo ingapheli iiyure ezingama-6. Ekubeni kunye nabo, isingqimba sosuku lokuvuka nokulala siphazamiseka, okukhokelela ekukhatheni kowesifazane. Umfanekiso weklinikhi uhamba kunye neyandi ephakamileyo yebele, indawo ephakamileyo yendawo ebonisa ngayo umntwana, umbele wesibeleko. Nangona kukho ukulwa, akukho zintlupheko ekuvuleni umlomo wesibeleko.
Umsebenzi obuthakathaka womsebenzi (inertia yesibeleko, ukunyaniseka) kuqukunye kakhulu, ubude kunye nobude bezophulaphulo. Oku kubangela ukululaza komzimba wesibeleko, ukuvula ubuthathaka komngcipheko wesibeleko kunye nomhlathi we-fetus. Ubuthathaka bentsebenzo buyintloko kunye nesekondari. Ngoko ubuthakathaka bokuqala bubonakala ukususela ekuqalekeni kokubeleka kwaye buhlala kude kube sekupheleni. Kwaye okwesibini kufaka indawo yomsebenzi oqhelekileyo. Ubuninzi bezinto ezibonakalayo zabasebenzi abanobubele kubonke abahlali be-parturients yi-5-6%.
Umsebenzi ogqithiseleyo wezenzo uqhelekileyo kubomama abanomdla kunye nabanokuzikhusela. Kucingelwa ukuba kubangelwa ukuphulwa komthetho we-cortico-visceral kunye nokuhlanganiswa kwezidakamizwa eziphambili kwiindawo eziphezulu (acetylcholine, oxytocin, prostaglandin, njl.). Ukuxilongwa komsebenzi ogqithiseleyo wezenzo kusekwa ngokusetyenzwa ngokukhawuleza nangokukhawuleza kwezabasebenzi. Ebonakaliswe kwimivumba enobudlova, elandelanayo ngexesha elifutshane kwaye kubangela ukuvula ngokukhawuleza kwesibeleko sesisu. Kule meko, ukubeletha kuthiwa i-impetuous, njengoko idlula ngaphakathi kweeyure eziyi-1-3. Ukuzalwa ngokukhawuleza kuyingozi kwimpilo yabasetyhini nabantwana. Ngokuqhelekileyo ziphela ngeentlobo eziphambili zesisu, i-cervix, i-perineum, i-clitoris. Kukho umngcipheko ophezulu wokuphazamiseka kwangaphambili kweplantal. Umntwana usoloko efumana i-hypoxia ye-intrauterine kwaye ufumana ingxaki yokuzalwa. Kukho amaninzi amaninzi xa ukuzalwa ngokukhawuleza kwenzeka ngokuthe ngqo kwitalato okanye kwisithuthi.
Umsebenzi wokungahambi kakuhle . Le ntsholongwane inxulumene nokungabikho kwezinto ezichaseneyo zeendawo ezahlukeneyo zesisu. Ukuphazamiseka kuphawulwa phakathi kweesahlulo esisekhohlo kunye nesokunene sesibeletho, izingxenye zayo eziphezulu nezantsi, phakathi kwezinye iindawo zesisu. Ukungaboni ngaso linye kubonakaliswe ngophezulu lwengqondo yesisu, ukuphazamiseka kwemivimbo, ukuchasana kwemisipha yeesetyhula. Ngaloo migaqo yokukhubazeka ibe yinto engavumelekanga, ibuhlungu. Ibhinqa ibuhlungu buhlungu kwi-back back and lower abdomen. Uhlobo lwesibindi lubonisa ukungabikho kwemisipha engalingani kwiindawo zayo ezahlukeneyo. Ukufundwa komsebenzi wesivumelwano esibelethwayo kwi-multichannel rekodi kugqiba i-arrhythmia kunye ne-asynchrony yezinto ezichaseneyo kumasebe athile. Ngokuqhelekileyo kukho iimfazwe zobude obuhlukeneyo kunye nobukhulu, i-uterus yiseyongeni eyongeziweyo, umlomo wesibeleko uvame ukuba "ungagqithanga", ukuvula kuyancipha. Ingxenye esele ikhona yintsana ihlala iselula ixesha elide okanye icinezelwe ukungena kwi-pelvis encinci. Emva kwexesha elithile, lo mfazi ukhathele, ukuzalwa kuyancipha okanye kuyeke. Ngenxa yokuphulwa kwe-uterine-placental circulation, u-hypoxia wesisu udlalwa rhoqo. Ixesha langemva nangemva kwexesha lokuhamba emva kwexesha lokuxhamla lixhatshazwa ngegazi.
