Mtima Wokhala Wosagwirizana Wosagwirizana ndi Ophedwa
Patent ductus arteriosus, kapena PDA, ali ndi vuto la mtima lobadwa m'mimba ya ana asanakwane kumene makina a arteriosus (chotengera chogwiritsira ntchito mitsempha ya pulmonary kuti ifike pansi) amalephera kutseka.
Izi zikachitika, zimalola magazi a mwana kuti alowe m'mapapo. Ngati PDA isanayambe kusamalidwa, ikhoza kuyambitsa matenda oopsa kwambiri , mtima wosagwirizana ndi mtima, komanso kupweteka mtima kwa mtima.
PDA imakhudza pafupifupi theka la onse omwe amagwiritsa ntchito mankhwala osokoneza bongo (ataperekedwa milungu isanathe kapena masentimita osachepera peresenti) ndi 15 peresenti ya adani omwe anabadwa pamasabata 30. Ndi ochepa chabe omwe ali ndi mapuloteni omwe ali ndi PDA.
Momwe Makhalidwe Achiberekero A Arteriosus Amachitira
Asanabereke, magazi a mwana amachotsedwa ndi placenta osati mapapo. Chifukwa chaichi, dongosolo la kupuma kwa mwana wakhanda ndi losiyana kwambiri ndi la mwana wakhanda.
Mu fetus, magazi ochepa amalowa m'mapapu odzaza madzi omwe amawathandiza kuti aziwathandiza. Zina zonse zimaperekedwa ku thupi monga magazi amachotsedwa kudzera mu ductus arteriosus, kulowa mu aorta, ndi kunja kwa mtima.
Pa kubadwa, ntchito ya kupuma imasintha: mwanayo amayamba kupuma mpweya, ndipo magazi aliwonse omwe amatumizidwa kumapapo ndi oksijeni. Panthawi imeneyi, ma ductus arteriosus amatanthauza kutseka. Ngati sizingatheke, ena mwa magazi otchedwa deoxygenated amapitirira mapapo ndipo amatumizidwanso ku aorta kumene amaponyedwa ku thupi mu mawonekedwe ochotsedwa.
Zizindikiro za Arteros Ductus Arteriosus
Mtima kudandaula nthawi zambiri ndi chizindikiro choyamba cha ana aang'ono a PDA. Pang'ono PDA sizingayambitse mavuto aakulu, choncho kawirikawiri sizitha kuchiritsidwa. Komabe, PDA ikakhala yaikulu, ikhoza kukhala ndi zizindikiro zowonjezereka, kuphatikizapo:
- Lethargy ndi zofooka
- Kupuma mofulumira kapena kupweteka kwambiri
- Kutentha kwakukulu (kwambiri)
- Tachycardia (chiwombankhanza cha mtima choposa kupuma kwabwino)
- Cyanosis (mtundu wa khungu la blue-ish chifukwa cha kusowa mpweya), makamaka kumapeto kwa m'munsi
- Dyspnea (kupuma pang'ono)
- Kudyetsa kosauka
- Kutaya thupi
- Kulephera kulemera
Kuzindikira ndi Kupatsa Ma Arteriosus Mipata ya Ma Patent
Ngati PDA ikukayikiridwa, chidziwitso cha mtima chidzachitidwa. Njirayi, yomwe imadziwikanso kuti mtima wa mtima, imagwiritsa ntchito mafunde ovuta kuti agwire mtima. Chifuwa cha X-ray chingathenso kulamulidwa (monga PDA zazikulu zingayambitse monga kukula kwa mtima).
Ngati apezeka, PDAs ing'onoing'ono idzazisiyidwa yokha. Ngati PDA ikuyambitsa zizindikiro, adokotala akhoza kusankha mankhwala omwe amachititsa mankhwala monga NeoProfen (mtundu wapadera wa ibuprofen) kapena indomethacin.
Kwa anthu omwe ali ndi matenda oopsa a m'magazi, zakudya zowonjezera zamadzimadzi zikhoza kulamulidwa kuti zisawononge madzi okwanira kwambiri omwe angapangitse kupweteka kwakukulu pamtima.
Nthawi zina, opaleshoni angafunike. Kwa makanda akusowa opaleshoni, njira yowonjezereka, yotchedwa opa opération opération, ingathe kuchitidwa. Ambiri safuna kuti opaleshoni ya mtima ikhale yotseguka koma m'malo mwake amagwiritsira ntchito kathete yomwe imalowetsedwa mu mitsempha ya chikazi kapena mitsempha yoyandikira kutsegula.
