Ngexesha lokukhulelwa okupheleleyo (ngaphandle kwezigaba zalo zokuqala), umntwana ujikelezwe ngu-amniotic fluid, okanye i-amniotic fluid. Lo mbandela, apho umntwana usuka khona, njengomdlali we-astronaut kwindawo evulekile, akagcini nje ngokumkhusela kwimpembelelo yangaphandle kwaye ugcina ukushisa okufunekayo, kodwa uthatha inxaxheba kwi-metabolism. Inani le-amniotic fluid yeenyanga ezithoba lihlala liguquka, kodwa kwixesha ngalinye lokukhulelwa kuneemimiselo zomsindo we-amniotic fluid. Ukugqithiswa kwindlela enye okanye enye ingathetha ukuba isiqhamo asilungile.
I-Norm ye-amniotic fluid ngexesha lokukhulelwa
Umthamo we-amniotic fluid ungama 600-1500 ml. Isixa se-amniotic fluid ngaphantsi kwe-500 ml sithathwa njengesi-anhydr, ngaphezu kwe-1,5-2 ilitha yi-polyhydramnios. I-ultrasound inokukunceda ukwenza uvavanyo oluchanekileyo.
Ngethuba le-nkqubo ye-ultrasound, i-ingcali ibonisa ukuba i-liquid ishicilelo. Ukuba kukho i-amniotic fluid eninzi, i-polyhydramnios ifumaneka, ukuba kukho amanzi amancinci. Kuphi na ukuphambuka kwimiqathango, ugqirha uqhuba uviwo olunzulu - ukubala isalathisi se-amniotic fluid. Ngaloo nto, umtya we-uterine uhlulwe ngokuqhelekileyo kwiingxenye ezilinganayo ezi-4 ngemigca emibini, enye enye idlulayo ngokuhamba, ecaleni komgca omhlophe wokukhulelwa, kunye nomnye-ophezulu kwizinga leenkaba. Kwinqanaba ngalinye, i-pocket (vertical space between the wall uterine kunye ne-fetus) iyalinganiswa, iziphumo zishwankathelwe, zinika isalathisi se-amniotic fluid.
Kwixesha ngalinye lokukhulelwa kuneemimiselo zalathisi. Ngokomzekelo, isalathisi se-amniotic fluid iyinto eqhelekileyo kwiiveki ezingama-22 ezinama-14,5 cm, okanye i-145 mm (ukuguqulwa okubonakalayo kufanele kufane phakathi kwe-89-235 mm). Kwaye kwiiveki ezingama-32 isalathisi se-amniotic fluid iya kuba yi-144 mm, kunye nokuphambuka kwi-77-269 mm. Imilinganiselo yemimiselo eyahlukeneyo yokukhulelwa ingafumaneka kwitheyibhile yoluhlu lwe-amniotic fluid index .
I-Amniotic index fluid - engafanelekiyo
Ngokuphathelele ukuphambuka ukusuka kwinto evamile ukususela kwimeko apho isalathisi se-amniotic fluid isezantsi okanye ngaphezulu kunokuba kuboniswe kwixabiso leetafile. Zombini i-polyhydramnios kunye ne-oligohydramnios zibonisa ukusetyenziswa kwentsholongwane ekuphuhlisweni komntwana okanye ngexesha lokukhulelwa.
Xa imeko ye-polyhydramnios, umntwana uhlala ehlala kwindawo engafanelekanga kwisibeleko, kwaye ngamanye amaxesha uphendulela intambo. Ukugqithisa kwamanzi amniotic kunokukhupha ukukhulelwa kwangaphambi kokuqala kunye nokuzalwa kwangaphambi kokuzalwa. Ukugqithisa kwesibeleko kunzima kakhulu ekuhambeni nasekuhambeni kwexesha lokugqibela, oku kungakhokelela ekubuthathaka komsebenzi kunye nokuphuhliswa kwegazi.
Izizathu ezibalulekileyo ze-polyhydramnios zi:
- ukungalungi (iinkqubo zesifo kunye nokutya) kunye ne-chromosomal engafanelekanga yomntwana;
- ukungafezeki komntwana;
- ukukhulelwa ngenxa ye-rhesus-conflict;
- isifo esithathelwanayo sowesifazane okhulelweyo;
- isifo sikashukela esikhatywayo kwabasetyhini abakhulelweyo.
Ukuba isalathisi se-amniotic fluid sibonisa ukungahambi kwamanzi kwi-trimester yesibini yokukhulelwa, ngoko-ke ingxaki yokuphila isenokuvela-ukunyanzeliswa kwentambo. Ukongezelela, umntwana ubanjwe kwisibeleko, ukunyakaza kwakhe kuncitshisiwe. Iintsana ezinjalo zihlala zifumana iingxaki kunye nomlenze womlenze kunye nomlenze emva kokuzalwa.
Ukuphuhliswa kokungondleki kunokubangela ukuba:
- ukungalunganga komntwana (i-excretory system kunye neentso);
- i-hypoxia kunye ne-fetp hypotrophy;
- ukungafezeki komntwana;
- ukukhulelwa kwangaphambili;
- sifo;
- isifo esiyingozi somkhuhlane;
- ukutshaya.
Ngokuchasene neenkolelo zabasetyhini abathile, umlinganiselo wamanzi ayiphuzayo awuchaphazeli utshintsho kumthamo we-amniotic fluid kwi-placenta.
