Inyaniso yokuba akuyiyo yonke into ehambelana ne-placenta, oomama abazayo, njengomthetho, baqaphele ukuhlolwa kwe-ultrasound. I-diagnostic eqhelekileyo iyagqubutha kwi-placenta. Siya kuqonda, kunokuba i-placenta iyancipha, kutheni le nkathalo ivela kunye nendlela yokuyichitha.
Ukunyameka kwe-Placenta - Izizathu
Isizathu esibalulekileyo sokunyuselwa kwepentecenta kukuguga kwangaphambili. Ngethuba lokukhulelwa, i-placenta idlula kulezi zigaba ezilandelayo: ukwakha (ukuya kwiiveki ezingama-16), ukukhula, ukukhula nokuguga. Kukho okubizwa ngokuba yi- degrees of mature of placenta :
- isitifiketi se-zero (ukuya kwiiveki ezingama-30) - isakhiwo se-placental sihambelana;
- Iidanga zokuqala (iiveki ezingama-27-34) - umgangatho we-placenta uba yi-wavy encane, iifomiti zetyukliya zivela;
- Isiqulatho sesibini (iiveki ezingama-34-39) - "ukuvutha" kunye nenani lokubalwa kwamanani;
- Isiqendu sesithathu (iiveki ezingama-37) - isakhiwo se-lobular esisezantsi, ukubalwa kwamanani.
Iqondo ngalinye lokukhula lihambelana nobukhulu obuthile bepentecenta. Ukuba i-ultrasound igqitywe yi-placenta enamandla, oku kuthetha ukuba indawo yomntwana ayikwazi ukwenza imisebenzi yayo ngokufanelekileyo. Nangona kunjalo, ukunyuka kwe-placenta kunokubangela ezinye izizathu:
- i-placenta yimbi ngaphezu kokuqhelekileyo kwiimeko zokukhulelwa eziyinkimbinkimbi yimpikiswano yeRh okanye i-dropsy;
- ukusabalalisa ukwanda kwamaplacenta (xa ikhula kakhulu kwaye ihlanganisa ubuninzi bomhlaba wangaphakathi wesibeletho) iyaqaphela ukuba isigulane sinesifo sikashukela;
- i-placenta eninzi ekukhuleleni ibonisa ukuba umama olindelekileyo unesifo segciwane okanye isifo esithintekayo;
- Ukunyuka kwe-placenta ngexesha lokukhulelwa kungabonwa ngokuphazamiseka kwamaplazi, i-gestosis kunye nokukhulelwa okubanzi.
Yintoni eyingozi ukunyuka kwepentecenta?
Ekubeni i-placenta enamandla ayinakukwazi ukuhlangabezana nemisebenzi yayo, umntwana ufumana ubuninzi obaneleyo be-oksijini kunye nesondlo. Oku kukhokelela kwi-fetal hypoxia, ukulibaziseka ekukhuleni nasekuphuhlisweni kwayo. Ukongezelela, kunokubakho usongelo lokupheliswa kokukhulelwa, kwaye kwiimeko ezinzima kakhulu umntwana angafa ngaphambi kokuzalwa.
Ukutywa kwe-placenta - unyango
Ukuba i-ultrasound ibonakalise i- placenta ekhudlwana , ugqirha uya kwongezelela ukuba afundise ezinye izifundo: i-cardiotocography, i-dopplerometry kunye neemvavanyo ze-hormone.
Umgaqo oyintloko wokonyango ukuphelisa imbangela yokwanda kwepentecenta. Kwakhona, abafazi abakhulelweyo banqunywe iivithamini kunye nokulungiselela unyango lwe-hypoxia kunye ne-fetal hypotrophy: i-Kurantil, i-Vktovegin, i-Essentiale, nabanye.
