Kodi Cordocentesis ndi chiyani?

Zamkati

• Nthawi yoti muchite cordocentesis
• Momwe cordocentesis yachitidwira
• Kodi kuopsa kwa cordocentesis ndi kotani?

Cordocentesis, kapena magazi a fetus, ndimayeso oyeza asanabadwe, omwe amachitika pambuyo pa masabata 18 kapena 20 atatenga bere, ndipo amatenga gawo la magazi a mwana kuchokera ku umbilical, kuti azindikire kusowa kwa chromosomal m'mwana, monga Down's Syndrome, kapena matenda monga toxoplasmosis, rubella, fetal anemia kapena cytomegalovirus, mwachitsanzo.

Kusiyanitsa kwakukulu pakati pa cordocentesis ndi amniocentesis, omwe ndi mayesero awiri opatsirana asanabadwe, ndikuti Cordocentesis imasanthula magazi amtundu wa mwana, pomwe Amniocentesis amangosanthula amniotic fluid. Zotsatira za karyotype zimatuluka masiku awiri kapena atatu, womwe ndi umodzi mwabwino kuposa amniocentesis, womwe umatenga pafupifupi masiku 15.

Nthawi yoti muchite cordocentesis

Zizindikiro za Cordocentesis zimaphatikizapo kupezeka kwa Down syndrome, pomwe sikungapezeke kudzera mu amniocentesis, pomwe zotsatira za ultrasound sizimadziwika.

Cordocentesis imalola kuphunzira za DNA, karyotype ndi matenda monga:

• Matenda amwazi: Thalassemia ndi sickle cell anemia;
• Matenda okutira magazi: Hemophilia, Matenda a Von Willebrand, Thrimmocytopenia Yodziyimira Pokha, Thrombocytopenic Purpura;
• Matenda amadzimadzi monga Duchenne Muscular Dystrophy kapena Matenda a Tay-Sachs;
• Kuti mudziwe chifukwa chomwe mwana wakhanda amapangidwira, ndipo
• Mwachitsanzo, kuzindikira ma hydrops a fetal.

Kuphatikiza apo, imathandizanso kudziwa kuti mwanayo ali ndi matenda obadwa nawo ndipo amathanso kuwonetsedwa ngati njira yothandizira kupatsirana magazi m'mimba kapena pakufunika kupereka mankhwala pochiza matenda a fetus, mwachitsanzo.

Phunzirani mayesero ena a matenda a Down Syndrome.

Momwe cordocentesis yachitidwira

Palibe kukonzekera kofunikira musanayezetse, komabe mayiyo ayenera kuti adayeza mayeso a ultrasound ndikuyesa magazi asanafike cordocentesis kuti awonetse mtundu wamagazi ndi HR factor. Kuyeza uku kumatha kuchitidwa kuchipatala kapena kuchipatala, motere:

1. Mkazi wapakati agona chagada;
2. Dokotala amapaka mankhwala oletsa ululu am'deralo;
3. Mothandizidwa ndi ultrasound, dokotala amalowetsa singano makamaka pamalo pomwe umbilical chingwe ndi placenta zimalumikizana;
4. Dotolo amatenga pang'ono pang'ono magazi a mwanayo ndi pafupifupi 2 mpaka 5 ml;
5. Chitsanzocho chimatengedwa kupita ku labotale kuti akawunikenso.

Mukamayesa mayeso, mayi wapakati amatha kumva kuwawa m'mimba motero amayenera kupumula kwa maola 24 mpaka 48 atayesedwa ndipo osagwirizana kwambiri masiku 7 kuchokera pa cordocentesis.

Zizindikiro monga kutaya kwamadzimadzi, kutuluka magazi kumaliseche, kupweteka, kutentha thupi komanso kupweteka m'mimba kumatha kuonekera atayezedwa. Kuti muchepetse ululu komanso kusapeza bwino zitha kukhala zothandiza kumwa piritsi la Buscopan, mothandizidwa ndi azachipatala.

Kodi kuopsa kwa cordocentesis ndi kotani?

Cordocentesis ndi njira yotetezeka, koma imakhala ndi zoopsa, monga mayeso ena aliwonse owopsa, motero dokotala amangofunsa ngati pali zabwino zambiri kuposa zoopsa za mayi kapena mwana. Zowopsa za cordocentesis ndizochepa ndipo zimatha kuwongoleredwa, koma kuphatikiza:

• Pafupifupi 1 chiopsezo chotenga padera;
• Kutaya magazi pamalo pomwe pamalowetsedwa singano;
• Kuchepetsa kugunda kwa mtima kwa mwana;
• Kuphulika msanga kwa nembanemba, komwe kungakonde kutumizidwa msanga.

Nthawi zambiri, dotolo amalamula cordocentesis pakakhala kuti amaganiza kuti matenda amtundu kapena matenda sanazindikiridwe kudzera mu amniocentesis kapena ultrasound.
