Nakuba ngokuvamile ibizwa ngokuthi "i-barium," ikhambi elisetshenziselwa ukuhlolwa kwezokwelapha empeleni alenziwe nge-barium yedwa. I-barium ehlanzekile iyisici esitholakala ngokuhlanganiswa nezinye izakhi ngoba iphendula ngomoya, ngakho-ke kufanele ikhishwe futhi ihlukaniswe, ngokuvamile ivela emabhodini amaminerali. Igama elithi barium lisuselwa egameni lesiGreki elisindayo, "barys." Ngaphandle kwezicelo zezokwelashwa, i-barium inezindlela ezihlukahlukene ezimboni zokukhiqiza kanye nokudoba futhi iyinhlanganisela yeziqhumane ezidala imibala eluhlaza.
Barium Sulfate
Isixazululo se-barium esisetshenziselwa ukuhlolwa kwe-radiological ngokuvamile kuvame ukubizwa ngamanye amagama afaka phakathi "i-contrast medium," "i-barium enema," "ukugwinya kwe-barium," "isidlo se-barium," noma "amaminisi e-barium." Lesi sici empeleni yi-barium sulfate (i-BaSO4), i-powder enezindawo ezithile eziyingqayizivele ezenza kube usizo ekuhloleni izithombe. Ukuze uqale, i-barium sulfate iyinsimbi, i-chalky, futhi ayichithi emanzini, okuyisakhiwo esenza ukuba sidlule emzimbeni ngaphandle kokubanjwa. Okwesibili, i-barium sulfate inzima futhi isakaza ama- x-ray , okusho ukuthi inganikeza umehluko kwifilimu ye-x-ray futhi isize isazi se-radiologist ukubona izakhiwo zangaphakathi. I-barium izobonakala ibe mhlophe nge-x ray, engenza kube lula ukubona izitho ezinjengezinambuzane ezincane , amathumbu amakhulu , isisu, kanye ne-rectum.
I-Barium sulfate ephuzile idlwengulwa kwamanye amanzi futhi yanikezwa iphunga ukuze kube lula iziguli ukuthi ziphuze.
Ngezinye izikhathi isiphuzo se-carbonated sinikezwa kanye nokuhluka kwe-barium, noma ukuhluka kwe-barium kuzoqukatha i-carbonation. I-Air izovela emnyama kwifilimu ye-ray, ihlinzeke ngokungafani kakhulu nomhlophe okuyoba umphumela we-akhaum yokugqoka ngaphakathi kwegciwane lokugaya. Lokhu kubizwa ngokutadisha kabili .
I-Barium sulfate esetshenziselwa ukuhlolwa kwe-digestive tract ephansi ifakwa ngaphakathi kwe-rectum ngokusebenzisa i-tube. Umoya ungabuye wengezwe nge-tube, ngezinye izikhathi ngemuva kokuba i-barium ikhishwe, ukuze i-radiologist ithole umbono omuhle wekoloni.
Imizamo Esebenzisa i-Barium
Isisombululo se-barium sisetshenziselwa ukuhlola okuhlukahlukene kwe-radiological, okufaka okuningi ukuthi abantu abanesifo sofuba (IBD) esibangelwa ukuvuvukala bangase babe yingxenye yokuxilongwa nokuphathwa kwabo. Ezinye zalezi zivivinyo zifaka:
- I-Barium enema : Lokhu kuhlolwa, okubizwa nangokuthi uchungechunge oluphansi lwamathumbu, luxube lwe-x-ray eyenziwa ngemuva kokuba isiguli sithola i-enema ye-barium sulfate.
- I-Barium igwinya : Ebizwa nangokuthi uchungechunge oluphezulu lwesisu, lokhu kuhlolwa kwenziwa ngemuva kokuphuza isisombululo se-barium. I-X-rays ithathwe ipheshana eliphezulu lokugaya njengoba i-barium sulfate idlula.
I-Barium Toxicity
Ukuhlolwa kwezidakamizwa usebenzisa i-barium sulfate kuphephile kakhulu. Uma isetshenziselwa kahle inqubo, i-barium ayitholi umzimba futhi ubuthi akuyona into ekukhathazayo. Nokho, kubalulekile ukuthi i-sulfate ye-barium isuswe emzimbeni ekupheleni kokuhlolwa. Uma ngabe uvivinye usebenzisa i-barium, udokotela wakho uzokunika imiyalelo emva kokuhlolwa.
Abanye abantu bangase babe nezihlalo ezimhlophe ngemva kokuhlolwa besebenzisa i-barium sulfate. Noma yiziphi izimpawu noma izimpawu ezingavamile emva kokuhlolwa, njengokuhlukunyezwa kwesisu, ukuqotshwa noma izitofu ezincane, kufanele kubikwe kudokotela wakho.
I-Barium esetshenziselwa ezinye izinhloso, njengeziqhumane, akufanele neze ingenwe ngoba iyingozi. Izimpawu nezimpawu ze-barium toxicity zingabandakanya:
- Ukungasebenzi kwamathambo
- Umfutho wegazi ophezulu
- Ukushaya kwenhliziyo okungavamile
- I-muscle twitching
- Ukukhubazeka
- Ukuhluleka kokuphefumula
