Umlomo wesibeleko uyilungu elidibanisa isisu esiswini kunye nesini kunye nemisebenzi ethile. Umsebenzi walo oyintloko ukhuselekile, ngoko ngenxa yokukhishwa kwangaphandle kwe-ywn okuvimbela ukungena kweflethi ukusuka kwisisu ukuya kwisibeleko. Umlomo wesibeleko uqukethe i-pharynx yangaphandle kunye yangaphakathi, kunye nokuvula ukuxhuma kwesibeleko kunye nesisu-isalathisa somlomo. Ubude obuqhelekileyo bomlomo wesibeleko ngexesha lokukhulelwa kufuneka kube ngu-3 cm, ngokunciphisa ubude bayo, thetha ngomngcipheko wokukhipha isisu kwaye unqume ukuba ngaba uya kuphulukana nesifo okanye unyango.
Ubude bomlomo wesibeleko ekukhulelweni
Njengoko sele kukhankanywe, umlomo wesibeleko wenza umsebenzi okhuselekileyo, ngakumbi ngexesha lokukhulelwa. Kwizigaba zokuqala, kuba lukhulu kakhulu, lenza iplagi encinci, eyona nto ibangela ukuba kungene ukungena kwintsholongwane. Ubude bendawo evaliweyo yomlomo wesibeleko ngaphambi kweveki ye-36 yokukhulelwa kufuneka ibe ubuncinane be-3 cm. Ingakanani umlomo wesibeleko onokumiselwa ngumntwana wesifo somzimba ngexesha lokuhlolwa kwe-obstetric yangaphakathi kunye nokuhlolwa kwe-ultrasound.
Ubude besibeleko ngeveki
Uphando oluqhutyelwe ngokukhethekileyo luye lwabonisa ukuxhomekeka kobude bomlomo wesibeleko kwixesha elibuhlungu. Ngoko, ubude bomlomo wesibeleko kwixesha leeveki ezi-10 ukuya kwimihla ngemihla kuyahluka kwi-35-36 mm. Kwiiveki ezingama-15 ukuya ku-19 ubude bomlomo wesibeleko buyi-38-39 mm, kwiiveki ezingama-20-24-40 mm, kwaye kwiiveki ezingama-25-29-41 mm. Emva kweveki ezingama-29, ubude bomlomo wesibeleko bunciphisa kwaye kwiiveki ezingama-30-34 sele sele zi-37 mm, kwaye kwiiveki ezingama-35 ukuya kuma-40 ukuya kwe-29 mm. Njengoko ubona, emva kweveki ezingama-29 umlomo wesibeleko uqala ukulungiselela ukuzalwa okuzayo. Emva kweeveki ezingama-36 zesisu, umlomo wesibeleko uqala ukuthambisa ngaphambi kokuzalwa , ukuphelisa, i-pharynx iqala ukupakisha kwaye idlulise isantya somnwe. Ubude bomlomo wesibeleko ekuzalweni kwakhona kwiiveki ezingama-13 ukuya kwe-14 kufuneka kube ngu-36-37 mm.
Ubude bomlomo wesibeleko ngaphambi kokuziswa
Ngokukhawuleza ngaphambi kokuzalwa, umlomo wesibeleko uvuthwa, ubizwa ngokuthi "ukuvuthwa." Intamo iyancwulwa, igxininiswe (ephakathi kwendawo ye-pelvis encinane), ubude bayo buyehla ukuya kwi-10-15 mm, kwaye i-pharynx yangaphakathi iyancipha nge-5-10 mm (idlula umnqweno womnwe okanye ngomunwe omnye). Kukhona ukululaza kwintsimbi yangaphakathi yentamo, kuba, njengokuba kunjalo, ukongezwa kwecandelo elingaphantsi lesisu. Ubude bomlomo wesibeleko ngexesha lokubeleka ngokukhawuleza luyancipha - luvuleka, ukwenzela ukuba umntwana angadlulisa umda wokuzalwa. Ekuqaleni komsebenzi kubangelwa intlungu ebundwini, ezibizwa ngokuba yiziphambano. Ngethuba lexesha le contraction, isivumelwano semisipha ye-muster kwaye ngexesha elifanayo i-cervix ivula. Xa ukuvulwa komlomo wesibeleko kufinyelela ku-4 cm, umsebenzi wokusetyenzwa usungulwe kwaye ukuvulwa kwayo kulandela 1 cm ngeyure.
Ubude bomlomo wesibeleko xa kusongelwa ukukhipha isisu
Ukunciphisa ubude bomlomo wesibeleko engaphantsi kwama-30 mm kwiiveki ezingama- 17 ukuya ku-20 zokukhulelwa kuthathwa njengento engapheliyo yomlomo wesibeleko . Ngaloo ntsholongwane, ubude bomlomo wesibeleko bunokufutshane, kwaye umntwana uhla ephumayo,
Sihlolisise okokude ubude bomlomo wesibeleko ngexesha lokukhulelwa nangaphambi kokubeletha. Kwaye kwaqhelana ne-patetism enjenge-istmiko-insufficiency, engenokuthiwa ukunciphisa ubude bomngcongolo wesibeletho ngaphantsi kwama-29 mm.
