Ukuzalwa kwangaphambi komntwana kuthathwa njengama-iveki angama-28 ukuya kwe-37 okukhulelwa. Kule meko, umlomo wesibeleko uvulwe ngaphambi kokuba ixesha elimiselweyo. Kwizonyango, kukho iimpawu ezahlukahlukeneyo zokuzalwa kwangaphambi kokuzalwa.
Ukuba ibhinqa liyabona ukuzalwa kwangaphambi kwexesha lokuqala (ngokuqhelekileyo liqhubeka lingenabuhlungu), oogqirha baya kuba nako ukunqanda ngexesha kunye nokugcina ukukhulelwa. Umama wesikhathi esizayo uya kuthunyelwa esibhedlele, apho uya kuqinisekisa ukuthotyelwa kokuphumla kombhede, utywala umthamo wamanzi kunye neemichiza eziyimfuneko eziza kunciphisa kwaye zikhulule umlomo wesibeleko. Ezi zilandelayo ziqhelekileyo kwaye zivela rhoqo iimpawu zokuqala zokubeletha:
ukuchoboza izicatshulwa okanye i-peristalsis yesisu. Le ngxaki inzima ukudibanisa nantoni na;
intlungu kwisisu esisezantsi, esinomlinganiso wokuqhawula. Kufana neentlungu zephambi ngaphambi okanye ngexesha lokuya esikhathini, zomeleleyo;
- uxinzelelo olunyukayo kwisisu kunye nesisini;
- Unxininisa kakhulu ukuba uchama;
okhulayo;
ukuphuma kumfazi kwanoma yimuphi umlinganisi;
- Ukunyuka okubukhali ekuhambeni komntwana.
Ukuba ibhinqa linemizuzu engama-8 (ngaphezulu kweeveki ezingama-30), ngoko kukho ingozi encinci kakhulu ebomini bomntwana. Ngokukodwa ukuba ukukhulelwa ngokwawo kwakungenasifo. Kungenzeka ukuba, emva kokubeleka ngeli xesha, umntwana uya kuchitha ixesha elithile kwiSebe elikhethekileyo elibizwa ngokuthi "ukuvuselelwa kweintsana." Ukuba umntwana uzalwa ngaphambi kweveki ye-30, isongelo ebomini bakhe siya kuba lukhulu ngakumbi. Kwiinkathalo ezinzulu, uya kuchitha malunga nenyanga okanye kwiinyanga ezimbalwa, de kube imeko yakhe izinzile, kwaye ubunzima abufinyeleli kumgangatho oqhelekileyo.
Xa kukho iimpawu zokubeleka kwangaphambi kokuzalwa, umfazi makabe ngokukhawuleza abize ugqirha okanye umbelethisi aze abike imeko yakhe ngaphandle kokulahlekelwa nkcukacha enye. Ugqirha, obone ubunzima beemeko, uya kuba nako ukucebisa umfazi okanye eze kwisibhedlele ukuze ahlolwe, okanye alele phantsi aze azinciphe. Enyanisweni, kwiimeko ezininzi, iimpawu ezinjalo zibuxoki. Isibeleko siyancipha, kodwa oku kuyintlukwano yesiqhelo. Ngoko umzimba ulungiselela ukuzalwa okuzayo. Ngokuqhelekileyo "ukulwa" okunjalo ngokukhawuleza kuyaphela kwaye kudlula embalwa imizuzu.
Kwimeko yokubhedlelelwa esibhedlele, lo mfazi uya kulungelelaniswa nabasebenzi: uya kunikwa isambatho, uya kudibaniswa kwinkqubo yokubeka iliso lomama ekuzalweni, umgqirha-gynecologist uza kubhekisisa isantya sokwandiswa komlomo wesibeleko. Ukuba ukuzalwa kwangaphambi kwangoko kusenokwenzeka ukuyeka, ngoko oogqirha baya kuphendukela kuncedo lwamachiza anokuncedisa ukunciphisa ingozi yegazi. Emva koko, iinqhezuzo maziphelile. Kwiimeko ezinqabileyo, ukuba kukho isongelo sangempela sokupheliswa kokukhulelwa, lo mfazi uya kufakwa esibhedlele de kube sekupheleni kokukhulelwa - ukugcinwa kokubeletha.
Ukuba ukuzalwa, iimpawu zazo ezibonakaliswe ngamandla ngokupheleleyo, akunakunqandwa, ngoko umntwana uya kunikwa ipempile ye-steroids ekhawuleza ukukhula kwemiphunga yengane. Oku kuya kukwandisa amathuba omntwana okusinda emva kokuphuma kwisibeleko sikamama. Umntwana ozalelwe ngaphambi kokuba ahlale engakhange ameme. Ngokukhawuleza wamisa kwigumbi ekhethekileyo, apho iimeko zenziwe khona, ngokukhawuleza kunokwenzeka kwi-intrauterine. Ngokuxhomekeke kwithuba apho umntwana azalwa khona, kunye nokulinganisa kwakhe, uya kuchitha kwigumbi elinjalo ixesha elifunekayo.
