Isiphumo esiphumeleleyo sokuzalwa ngokuqhelekileyo kuxhomekeke kumsebenzi womlomo wesibeleko, owathi uxhomekeke kwinqanaba lamahomoni egazini lomfazi ohamba phambili. Ngexesha lokukhulelwa okupheleleyo, utshintsho luyenzeka kwi-cervix, kodwa ngaphambi kokuqala kobasebenzi, kufuneka ivalwe ngokuqinileyo, ngaphandle koko ukukhulelwa kungaphazamiseka ngaphambi kwekota.
I-Cervix ngaphambi kokuziswa
Ngaphambi kokubeleka, phantsi kweempembelelo ze-horagone ze-prostaglandin, kukho iinkqubo kwi-cervix yesibeleko ebizwa ngokuba yi-maturation. Kukho isixa esithile esikuvumela ukuba uhlalutye umlomo wesibeleko ngaphambi kokuba uzalwe, ngelixa uvavanya imilinganiselo emi-3: ukulingana, ubude bomlomo wesibeleko, ukuguguleka kombhobho wesibeleko kunye nommandla wendawo kwi-axis ye-pelvis. Umlinganiselo ngamnye uvavanywa ngexesha loviwo lwe-cervix ukusuka kwi-0 ukuya kweyesi-2:
- Amanqaku angama-0-2 ahambelana nomlomo wesibeleko omdala wesibeleko ngaphambi kokunikezelwa;
- amanqaku ama-3-4 amanqaku ahambelana nomlomo wesibeleko okhulileyo okhulileyo.
- amanqaku ama-5-6 - umlomo wesibeleko ovuthiweyo.
Ngendlela eqhelekileyo yokukhulelwa, umlomo wesibeleko ufanele ukhule ngeeveki ezingama-38-39. Ngaphantsi kweempembelelo ze-hormone kukho ukunciphisa umlomo wesibeleko ngaphambi kokunikezelwa, ukugxininiswa kwayo ngokubhekiselele kumgca wocingo we-pelvis. Ubude bomlomo wesibeleko ngaphambi kokuzalwa kuncitshiswa ukuya kwi-10-15 mm kunye nokuvulwa komphetho wangaphandle ngu-1-2 cm, oko kukuthi, iyadluliselwa ngomunwe we-obstetrician.
Ukuhluthwa komlomo ngaphambi kokubeletha
Ukuvulwa komlomo wesibeleko ngaphambi kokuba kuzalwe kwenzeka kancane kwaye kufinyelele kwi-10 cm (itywala yomlomo kufuneka idlule iminwe emihlanu yesigqirha). Ukudalulwa komlomo wesibeleko kubasebenzi kuyahlula zibe zigaba ezi-2: i-latent (ivule ukuya kwi-4 cm) kwaye isebenza (ukusuka kwi-4 cm ukuya kwi-10 cm). Isigaba esisezantsi kwi-primiparas sihlala kwiiyure ezingama-6-9, ekuzalweni kwakhona kweeyure ezingama-3-5. Ukususela ekuqaleni kwesigaba esisebenzayo, izinga lokuvulwa komlomo wesibeleko liba ngu-1 cm ngeyure. Umlomo wesibeleko osisithambileyo sesisu uvuleka lula ngongcinezelo wentloko yesisu kunye nesigxina esingaphantsi kwesitya sokutshatyalaliswa kwisitishi sayo.
Unokukunceda njani ukunyuka kwebele?
Njengamanje, abambalwa abafazi namhlanje banokuziqhayisa ngempilo ephezulu. Ukukhawuleza kwantyaba yobomi, uxinzelelo oluqhubekayo, ukungondleki kakuhle kunye nokunyuka kwemvelo kungaphazamisa umkhiqizo we-prostaglandines kumzimba wesetyhini, apho iinkqubo zokuvuthwa komlomo wesibeleko kunye nokuvula kwayo kuxhomekeke ngqo. Ukuze kuphuculwe ukuvuthwa kwe-cervix kunye nokuvula kwayo ekuzalweni, ukulungiselela amachiza kusekelwe kwi-prostaglandin. I-analogue ye-prostaglandin E1 (iSaitotec) okanye i-analogue ye-prostaglandin E2 ngendlela ye-gel (Prepidil) ikhuthaza ukuvuthwa komlomo wesibeleko ngeeyure eziliqela. Kodwa zisetyenzisiweyo kakhulu ngenxa yeendleko eziphezulu. Xa ubeletha, unokusebenzisa i-narcotic and non-narcotic analgesics (promedol, fentanyl, nalbuphine), kodwa kunokubangela ukucindezeleka kokuphefumula ebusweni emva kokuzalwa kwaye kubangele isidingo sesilada. Indlela efanelekileyo kunye nekhuselekileyo, eyanceda ukuvula umlomo wesibeleko yintsholongwane ye-epestural anesthesia. Iqhutywe ngu-anesthesiologist phantsi kweemeko ezingekho phantsi. Ayinakuchaphazela kakubi umntwana, ekubeni izidakamizwa ezilawulwayo azingena kwigazi, kwaye kungekhona nje ukukhawuleza ukuvulwa komlomo wesibeleko, kodwa kwenza inkqubo ingenabuhlungu.
Ukuphuka komlomo
Kungcono umbele wesibeleko ngaphambi kokuzalwa, akunakwenzeka ukuba kuphuluke ngexesha lokuzalwa komntwana. Kwakhona isizathu sendawo
Ngaloo ndlela, ukuvuthwa komlomo wesibeleko kuyaphulwa ngenxa yezizathu ezithembekileyo kwaye azixhomekeke kulo mfazi ngokwakhe. Ngoko ke, lo mfazi ngokwayo unokunceda ukulungiselela ukuzalwa komzimba wakhe, ukujonga umbuso wemihla, ukutya ngokufanelekileyo kwaye ungacingi ngeengxaki.
