I-amniotic fluid yindawo yokuqala yokuhlala umntwana. Ziyondla, zikhusele kwaye zenze ucoceko. Ukuphuhliswa nokukhuselwa komntwana kuxhomekeke kwisixa kunye nokubunjwa kwe- amniotic fluid . Ngethuba lokuqala, i-amniotic fluid ibonakala ngeveki ye-8 yokukhulelwa, kwaye i-filtrate ye-plasma yegazi.
Kufuneka ukuba amniotic fluid ibe yinani?
Ukuba sithetha ngomthamo, umlinganiselo oqhelekileyo we-amniotic fluid uhamba phakathi kwe-600-1500 ml. Ukususela kwinani le-amniotic fluid kuxhomekeke kakhulu, kuba banika umntwana inkululeko yokuhamba, imetabolism eqhelekileyo kwaye ukhusela intambo ekucinyeni.
Umlinganiselo we-amniotic fluid ngqo kuxhomekeke kwixesha lokukhulelwa. Ngokunyuka kwithuba, i-volume yabo iyanda. Inani le-amniotic fluid iiveki zibukeka kanje: kwiiveki ezili-10 umfazi okhulelwe unama-30 ml we-amniotic fluid, 13-14 - 100 ml, kwiiveki ezingama-18 ukuya kwe-20-malunga ne-400 ml. Ngeveki yama-37-38 yokukhulelwa inani le-amniotic fluid liphezulu kwaye li-1000-1500 ml.
Ekupheleni kokukhulelwa, lo mqulu ungancitshiswa ube ngu-800 ml. Kwaye xa kwenzeka i-overnifting ye-amniotic fluid, kunokuba ngaphantsi kwama-800 ml. Ngako oko, ubunzima be-placenta kunye ne-amniotic fluid ephuma ekuzalweni komntwana malunga ne-1300-1800 mg. Kule meko, i-placenta ikhula ukusuka ku-500 ukuya ku-1000 mg, kwaye ubunzima be-amniotic fluid bu malunga ne-800 mg.
Ulwaphulo-mthetho kwinani le-amniotic fluid
Ngamanye amaxesha, ngesinye isizathu okanye esinye, umthamo we-amniotic fluid ayihambelani nesiqhelo - kukho ngaphezulu okanye ngaphezulu kunikwe okanye mhlawumbi, ngaphantsi. Ukuba inani le-amniotic fluid liyancishiswa, lithetha ukungabikho kokukhulelwa kokukhulelwa . Inani elikhulu le-amniotic fluid libizwa ngokuthi i-polyhydramnios.
Inani elincinci le-amniotic fluid lisongela i-hypoxia engapheliyo ye-intrauterine, kuba le meko inciphisa amathuba okuhamba ngokukhululeka komntwana. Inambuzane igxininisa intsana, kwaye yonke iminyango yakhe ivalelwa ngumfazi okhulelweyo. Kukho umngcipheko wophuhliso kumntwana wezo mpazamo njengokuphakama okuncinci kunye nesisindo ekuzalweni, i-clubfoot, ukukhawuleka komgudu, ukuma kunye nobunzima besikhumba.
Ukuba sithetha ngezizathu zokungondleki, eziphambili zizifo ezithathelwanayo nezikhuphayo kumama, ukuphazamiseka kwamagciwane, ukungafezeki kwamatoklacental, ukungaqhelekanga kwenkqubo yokucoca komntwana. Ngokuqhelekileyo into enjalo iboniswa kwelinye lamawele afanayo ngenxa yokusabalalisa ukungalingani kwe-amniotic fluid.
Ukwandisa inani le-amniotic fluid, kuyimfuneko, okokuqala, ukunyanga okanye ukunciphisa eso sifo esaholela ekunyukeni kwamanzi. Ukongezelela, unyango lunikezelwa ukuphucula ukuphuma kwegazi, ukubuyisela ukutshintshwa kwegesi kunye ne-plaque metabolism.
Into echasene nayo i-polyhydramnios. Olu xilongo lwenziwe ukuba ngaba ngaphezu kwe-2 ilitha yamanzi afunyenwe kwi-ultrasound kumfazi okhulelweyo. Iimbangela ze-polyhydramnios ziphulo lophuhliso lweenkqubo zesebe kumntwana (ukutywala,
I-Polyhydramnios inokukhokelela kumanzi angaphambi kwangoko, ngoko kuyimfuneko ukulwa nale nto. Unyango lubandakanya ukukrazula (ukuba kunokwenzeka) yezizathu ezibangele ukugula, kunye nokuthatha imishanguzo encedisa ukulungelelanisa umthamo we-amniotic fluid.
Kwiimeko ezinzima kakhulu, kucetyiswa ukuba uye esibhedlele kwaye ube phantsi kolawulo lwezonyango rhoqo. Uhlolo olupheleleyo lucetyiswa ukuba lubone ukuphazamiseka okusemandleni ekuphuhliseni umntwana.
