barium /bar·ium/ (Ba) (bar´e-um) a chemical element, at. no. 56. Its acid-soluble salts are poisonous; causing gastrointestinal symptoms followed by severe, sometimes fatal hypokalemia with paralysis.

barium (Ba)
[ber′ē·əm]
Etymology: Gk, barys, heavy
a pale yellow, metallic element classified with the alkaline earths. Its atomic number is 56; its atomic mass is 137.36. The acid-soluble salts of barium are poisonous. Barium carbonate, formerly used in medicine, is now used to prepare the cardiac stimulant barium chloride; fine, milky barium sulfate is used as a contrast medium in radiographic imaging of the digestive tract.

barium sulfate,
n a white, finely ground, tasteless powder that is insoluble in water, solvents, and solutions of acids and alkalis; used in radiography as a contrast medium because of its opacity to roentgen rays and as a protective barrier in plaster walls.
barium
a chemical element, atomic number 56, atomic weight 137.34, symbol Ba. See Table 6. Soluble salts, e.g. the chloride and the carbonate, are toxic.
barium burger, barium meal
a mixture of barium and solid food, used as a contrast medium in radiographic studies of the esophagus, instead of liquid barium mixtures.
barium chloride
used as a rodenticide. The baits are attractive to dogs. Clinical signs include salivation, convulsions and paralysis.
barium deficiency
preliminary experiments showing that diets deficient in barium fed to rats and guinea pigs depress growth have been neither invalidated nor confirmed.
barium enema
a dilute (5 to 20%) suspension of barium is introduced into a colon that has been emptied by starvation and previous enema.

barium-impregnated polyethylene spheres (BIPS)
radio-opaque markers used to demonstrate intestinal obstruction and motility disorders; the spheres are given orally and their movement can be tracked radiographically.
barium meal
a strong (usually 100%) suspension of barium sulfate is administered to an animal which has been starved for at least 12 hours.
barium study
x-ray examination using a barium mixture to help locate disorders in the esophagus, stomach, duodenum, and the small and large intestines. Called also barium test.

a water-insoluble salt used as an opaque contrast medium for x-ray examination of the digestive tract.
barium swallow
a small amount of barium paste or liquid administered orally and observed radiographically or by fluoroscopy for examination of swallowing and esophageal function.
barium test
barium study.
