I-Oxytocin yilungiselelo lomonakalo lwe-hormone kwaye lifana nesakhiwo kunye nesenzo kwi-hormone efanayo yomntu. Isenzo salo emzimbeni sancitshiswa ekuvuseleleni izihlunu ezibushelelekileyo, eziza kubangela iziphambano ze-uterine. Ngenxa yeli propati, i-oxytocin isetyenziswa ngokubanzi kwi-gynecology. Ngokukodwa, i-analogue yamayeza e-hormone oxytocin isetyenziselwa ukukhipha isisu.
Ukungena emzimbeni wesifazane okhulelwe, i-oxytocin inokukhupha isisu, ukuphazamisa izithintelo. Ukukhupha isisu, le nkunkuma isetyenziswe ikakhulukazi kumanyathelo okuqala okukhulelwa. Nangona le ndlela yindlela engapheliyo ekugqibeleni ukukhulelwa kokukhulelwa, kuyingozi ukuba kufunyanwe ukuphuma kwegazi. Ngako oko, i-oxytocin isetyenziswe njengendlela yokukhipha isisu, ngelixa i-embryo ibuncinane kwaye ingakafiki ixesha lokunamathela ngokuqinile eludongeni lwesisu.
Ukusetyenziswa kwe-oxytocin ekukhutheni
Kodwa kukho imeko xa ukusetyenziswa kwayo kuyimfuneko kwimigqaliselo enzulu, umzekelo, xa kukho ukukhulelwa okhenkcelayo kwi-trimesters yesibini neyesithathu. Ukukhanda isisu kulesi simo kuya kuba nzima, kuya kubakho ukuchukumisa ukubhujiswa kwangaphakathi kwe-fetus ngoncedo lwezixhobo, okanye ukwenza icandelo le-cavity, kunye nokufakwa kwe-oxytocin, eqinisweni, kubangela ukuba kubeleke. I-oxytocin isasetyenziswa kwiimeko zokuphelelwa kwesisu okungapheliyo ukusiza isibeleko ukuba uzihlambulule isisele se-embryo efileyo kunye ne-endometrium. Ukukhuthazwa ngokufanelekileyo kwemisipha ehlazileyo kubangelwa kuphela kwiimeko ezifuna ukupheliswa kokukhulelwa, kodwa nakwixesha lokuzalwa ekupheleni kwayo. I-oxytocin isetyenziselwa ukukhulelwa kwiiveki ezingama-41-43, xa ukuzalwa kungekhona ngokwemvelo, kwaye umntwana ogqithisiweyo uqala ukubandezeleka nge-hypoxia. Le hormone isetyenziselwa ukwandisa abasebenzi kwiimeko zabasebenzi abancinci, okunciphisa ixesha lokuhambisa.
Oxytocin, njengendlela yokonyango
Kukwafanelekile ukusebenzisa i-oxytocin ngokuhlukana okungaqinisekanga kwe-endometrium emva kokukhipha isisu okanye isigaba se-caesarean.
Ngamaxesha amaninzi okanye i-bleto, i-oxytocin inqunywe kwiyeza elincomekayo kunye neendlela zokubuyisela igazi. Ngokumalunga nawo onke angentla, kukho iimeko xa i-oxytocin isetyenziselwa iinkqubo eziqhubekayo kwiingcambu zentloko. Ukuqaliswa kwalo emzimbeni womfazi ongumongikazi kubangela ukuphuma kwebisi.
Ukungqinelana nokusetyenziswa kwe-oxytocin
Ukungqinelana nokusetyenziswa kwe-oxytocin yiyo:
- indawo engafanelekanga yefubus kwisibeleko (oblique okanye esicatshulwayo). Ekubeni ukuzalwa kwemvelo kuqokelelwe ngokungafanelekanga ngumntwana akunakwenzeka, ukuvuselela i-oxytocin kungabangela ukufa kwakhe, kubangele ukuphazamiseka okukhulu;
- i-placenta previa (kule meko i-oxytocin inokubangela ukuphazamiseka kweplantshi, ukuphuma kwamanzi kwaye, ngenxa yoko, ukufa komntwana);
- Ubunzima bekhanda kwisibeleko (umzekelo, kwinqanaba elidlulileyo). Kule meko, amathuba okukhulelwa kwesibeletho kwi-rumen inkulu;
- i-pelom ne-clinic encinci ye-pelvis yowesifazane ekubelethweni
(ngokwalo, ukungafani phakathi kobunzima bekhanda lomntwana kunye nobukhulu bekhanda lomama ekuzalweni kungakhokelela ekulimaleni kumama nomntwana); - usongelo lokukhulelwa kwesisu;
- Iimpawu eziqinileyo ze-uterine (kwimiqathango yokuphambana okunzima, ukuvuselela ngokweqile kunokukhokelela ekugqibeleni kwesibeletho).
Imiphumo ye-oxytocin
I-Oxytocin ivumelekile ukuba isetyenziswe kuphela kwisiko lonyango phantsi kolawulo lugqirha. Le ndlela yokuqapha iyasebenza ngoba le hormone inokubangela ukuvuselela ngokwaneleyo izihlunu ezihamba kakuhle, ezinokubangela imeko yokuphuka kwesisu kwaye kubangele ukuvula ukuphuma.
