Pa nthawi yonse yoyembekezera, mwana wamwamuna ali m'madzi - ndi chikhodzodzo chodzazidwa ndi amniotic fluid, amatchedwanso amniotic fluid . Mpaka nthawi yoberekera, kuphulika kumeneku kumachita ntchito zambiri - kumachepetsa kutentha kwa thupi, kumagwiritsa ntchito njira zamagetsi zamadzimadzi, zimapereka kukonzekera kugwira ntchito bwino kwa ziwalo zatsopano. Pamene nthawi yoberekera ikubwera, chikhodzodzo chikuphuka - ndipo amniotic yonse imatuluka - njirayi imatchedwa "madzi".
Pafupifupi chiwerengero cha amniotic madzi ndi chizoloŵezi
Ndi njira yothetsera ultrasound, dokotalayo amayenera kuyeza kuchuluka kwa amniotic fluid, poyerekeza ndi mlingo wa mimba yapatsidwa ndikuyang'ana kusintha kotheka momwe akuwonekera. Chizoloŵezi ndi kuchuluka kwa amniotic madzimadzi amawerengera nthawi iliyonse yogonana ndipo amapezeka mu tebulo ili m'munsiyi:
Deta yomwe ikupezeka pa tebuloyi ndiyomweyi, chifukwa dokotala akuyang'ana mwachindunji chizindikiro ichi panthawi ya ultrasound, poganizira momwe zimachitikira mayi wapakati ndi zizindikiro zonse za thanzi lake ndi mwanayo m'mimba. Amniotic yamadzimadzi amasiyana kwambiri ndipo mwachizoloŵezi pa nthawiyi ndi nthawi yachidule. Gome limapereka lingaliro lokha la malire a amniotic fluid, choncho chidziwitso chomaliza chimangopangidwa ndi dokotala wochokera ku ultrasound.
Chizoloŵezi cha amniotic fluid ndi chimodzi mwa mfundo zofunika kwambiri pa matenda opatsirana, popeza chizindikiro ichi ndi chitsimikizo cha matenda omwe ali ndi mimba. Pamene kugwiritsidwa ntchito kwa ziwalo zowonongeka kwa mwanayo kumasokonezeka, ma polyhydramnios amapezeka nthawi zambiri, ndi matenda ku mbali ya thupi la mayi - nthawi zambiri kulikusowa kwa zakudya. Mnogovody mwa amayi omwe ali ndi pakati amalingalira mndandanda wotere wa amniotic fluid, umene umaposa chizoloŵezi (pambaliyi - kumapeto kwa maulendo) ndi nthawi 1.3-1.5. Kuperewera kwa zakudya m'thupi (kotala pang'ono kupitirira malire a m'munsi) kumakhala ndi kubereka kovuta komanso kubadwa kwa mwana. Ma polyhydramnios ndi owopsa ngati kuopseza chiberekero ndi kufotokoza kwa mwana.
