Ngakhale kuti kawirikawiri amatchedwa "barium," yankho limene limagwiritsidwa ntchito pa mayesero achipatala silimapangidwa ndi barium yokha. Buluu yoyera ndi chinthu chophatikizapo ndi zinthu zina chifukwa zimayendetsedwa ndi mpweya, choncho zimachokera kumalo osungirako mchere. Mawu akuti barium amachokera ku liwu lachi Greek lolemera, "barys". Pambuyo pa ntchito zawo zachipatala, barium imagwiritsa ntchito zosiyanasiyana mmakampani opanga ndi pobowola komanso imakhala yowonjezera pamoto zomwe zimapanga mitundu yobiriwira.
Barium Sulfate
Njira yothetsera vutoli yomwe imagwiritsidwa ntchito poyezetsa magazi nthawi zambiri imatchedwa mayina ena kuphatikizapo "sing'anga," "barium enema," "swallowum swallow," "chakudya cha barium," kapena "salt barium." Zinthu izi ndi barium sulfate (BaSO4), ufa womwe uli ndi zinthu zina zomwe zimapangitsa kuti zikhale zogwiritsira ntchito zojambula. Poyambira, sulfate ya barium imakhala yachitsulo, yosakanikirana, ndipo sipasuka m'madzi, yomwe ndi malo omwe amachititsa kuti ipitirize kupyola mu thupi popanda kutengeka. Chachiwiri, sulfate ya barium ndi yofalikira ndipo imabalalitsa x-ray , zomwe zikutanthauza kuti zimatha kusiyanitsa filimu ya X-ray ndikuthandizira katswiri wa zamagetsi kuti aone zochitika za mkati. Buluuyo idzawoneka yoyera pa x-rayi, yomwe ingathandize kuti zikhale zovuta kuona ziwalo monga katumbo kakang'ono , matumbo akulu , m'mimba, ndi kachilombo.
Barium sulphate yomwe yaledzera imayambira mumadzi ena ndipo amapatsa zonunkhira pofuna kuti odwala amve mosavuta.
Nthaŵi zina kumwa mowa umaperekedwanso pamodzi ndi kusiyana kwa barium, kapena kusiyana kwa barium kuli ndi carbonation. Mpweya udzawoneka wakuda pa filimu ya X-ray, yopereka kusiyana kosiyana ndi zoyera zomwe zidzakhala chifukwa cha kupaka barium mkati mwa kapangidwe ka zakudya. Izi zimatchedwa phunziro losiyana-siyana .
Barium sulphate yomwe imagwiritsidwa ntchito pofuna kuchepetsa mayesero amagazi amaikidwa mu rectum pogwiritsa ntchito chubu. Mpweya ukhoza kuwonjezeredwa kudzera mu chubu, nthawi zina pambuyo poti bariamu imatulutsidwa, kuti dokotala wa radiologist awone bwino colon.
Mayesero Amene Amagwiritsa ntchito Barium
Njira yothetsera ubongo imagwiritsidwa ntchito pazoyezetsa magazi zosiyanasiyana, kuphatikizapo ambiri omwe anthu omwe ali ndi matenda opatsirana (inflammatory disease) (IBD) angakhale ngati mbali ya matenda awo. Zina mwa mayeserowa ndi awa:
- Barium enema : Mayesowa, omwe amatchedwanso m'mimba otsika m'mimba, ndi mndandanda wa x-rays zomwe zimachitika munthu wodwala atalandira mchere wa barium sulphate.
- Barium amadyetsa : Amatchedwanso minofu yakumtunda m'mimba, mayesowa amachitika atatha kumwa mowa wa barium kusiyana. X-ray imatengedwa kuchokera kumtunda wapamwamba ngati digito ya barium sulphate imadutsa.
Barium Toxicity
Mayesero azachipangizo pogwiritsira ntchito barium sulfate ali otetezeka kwambiri. Mukagwiritsidwa ntchito moyenera, njira ya barium siidakali ndi thupi komanso poizoni sizingakhale zodetsa nkhawa. Komabe, nkofunika kuti sulfate ya barium ichotsedwe ku thupi kumapeto kwa mayesero. Ngati mwakhala ndi mayeso pogwiritsa ntchito barium, dokotala wanu adzakupatsani malangizo atatha mayeso.
Anthu ena amatha kukhala ndi zoyera pambuyo pa mayeso pogwiritsa ntchito barium sulphate. Zizindikiro kapena zozizwitsa zonse pambuyo pa mayesero, monga kupweteka kwa m'mimba, kudzimbidwa , kapena zochepa, ziyenera kuuzidwa kwa dokotala wanu.
Bariamu yomwe imagwiritsidwa ntchito pazinthu zina, monga zozizira, siziyenera kuyamwa chifukwa ndizoopsa. Zizindikiro za bongoum toxicity zingaphatikizepo:
- Matenda a m'mimba
- Kuthamanga kwa magazi
- Kuphatikizika kwa mtima
- Kusokoneza minofu
- Kufa ziwalo
- Kulephera kupuma
