Fetal doplerography

Dopplerography imatanthawuza njira zamakono zophunzirira, zomwe zimapangidwira kuunika magazi m'mimba. Mothandizidwa ndi njirayi, chikhalidwe cha ziwiya za placental system chidziwika. Kuti muzitsatira, palibe zina zowonjezera zofunika, chifukwa zipangizo zamakono zamakono zamakono zili ndi ntchito ya dopplerograph.

Kodi njirayi ikuchitika bwanji?

Dopplerography isanafike, dokotala amadziwa malo omwe akufufuzidwa: zotengera za uteroplacental magazi, zotengera za ubongo, mtima, chiwindi. Pogwiritsa ntchito Doppler ntchito ndi kutumiza njenjete ku limba loyang'aniridwa, adokotala adzalandira chithunzi pazenera. Zipangizozi zidzasanthula deta izi zokha. Ndondomekoyi ndi yopanda kupweteka komanso yaifupi-10-15 Mphindi.

Kodi aliyense akuuzidwa dopplerography?

Kujambula magazi kumatuluka kwa amayi onse apakati pa sabata la 32 la kubala mwana. Pankhani ya zizindikiro zapadera (kusasinthika, kusaikira kwa intrauterine kuchepetsa kukula), phunzirolo likhoza kuchitidwa kale kuposa nthawi yomwe yasonyezedwa (masabata 22-24).

Dopplerography imayankhulidwanso pazinthu monga:

• multiple pregnancies;
• Matenda a Rhesus ndi amamayi.

Komanso, pamene maselo a mwanayo sagwirizana ndi msinkhu wovuta, mwana wamwamuna wa fetus ndi dopplerography angapatsidwe kuyesa momwe magazi akuyendera.

Ndi magawo ati omwe amapezeka mu Doppler?

Zonsezi, pali mitsempha iwiri ndi mitsempha imodzi mu umbilical chingwe, yomwe imapatsa fetus ndi zakudya ndi mpweya. Kotero, pa mitsempha magazi amapita kwa mwanayo molunjika kuchokera ku placenta. Kupyolera mu mitsempha, zomwe zimachokera ku zowonongeka zimachotsedwa ku mwanayo.

Kuti ntchito yodalirika ikhale yoyenera, kukana pamakoma a mitsempha kumakhala kotsika. Ngati chombocho chikuchepa, kusowa kwa oxygen kukukulirakulira, komwe kumakhudza kwambiri vuto la intrauterine.

Kodi kusokonezeka kwa magazi kumapezeka bwanji ndi Doppler?

Pochita zojambula zojambulajambula za sitima za fetal, zizindikiro zotsatirazi zimakhazikitsidwa:

• magazi othamanga velocity,
• kupanikizika,
• kutsika kwa mitsempha ya mitsempha.

Poyerekeza ndi zomwe zimapezeka, mavuto osiyanasiyana a magazi amatha kupezeka. Choncho, allocate:

• 1 digiri A - pamene pali vuto lopanda magazi m'mayendedwe a magazi, koma maselo a fetaline amatha kugwira bwino;
• 1 digiri B - imawululidwa pamene kachitidwe ka fetusa kamakhala kovuta, ndipo magazi otuluka m'mimba sakhala ndi chisokonezo;
• 2 digiri - ngati pali kuphwanya pomwepo m'zinthu ziwiri, koma sizitsutsa;
• 3 digiri - amachitika pamene kuphwanya kwa fetal plasta system ndi kofunikira, ndipo magazi amatha kuthamangitsidwa.

Pachifukwa chokwanira, amayi omwe ali ndi pakati akuwonekera nthawi yonse yotsalayo. Kufufuza ndi ultrasound kumachitidwa kamodzi pa sabata. Pa nthawi imodzimodziyo, ngati CTG idawonetsere kuti palibe kuphwanya ndi kuopseza kwa mimba yowonjezera, kubadwa kumachitika nthawi.

Pa nthawi yachiwiri, kulamulira kwa chikhalidwe cha amayi oyembekezera kumachitika masiku awiri. Chiwonetserocho chimatenga masabata makumi awiri ndi awiri, ndipo pakakhala zizindikiro, zimayambitsa gawo lopuma.

Pogwiritsa ntchito madigiri 3, amayi akuyang'anitsitsa tsiku ndi tsiku ndi madokotala, ndipo pokhala ndi zoopseza za mimba, gawo loperewera likuchitidwa.

Motero, dopplerography ya fetus ndi njira yofufuza imene imayambitsa ngati magazi amatha kuyenda bwino komanso ngati mwanayo akumva ululu pambaliyi.
