The use of barium during pregnancy is safe for the baby; however, X-rays may result in harm. [4] Barium sulfate suspension is typically made by mixing barium sulfate powder with water. [1] It is a non-iodinated contrast media. [5] Barium sulfate has been known since the Middle Ages. [6] In the United States it had come into common medical use ...
As barium sulfate has a high melting point and is insoluble in water, it is used as a release material in casting of copper anode plates. The anode plates are cast in copper molds, so to avoid the direct contact of the liquid copper with the solid copper mold, a suspension of fine barium sulfate powder in water is used as a coating on the mold ...
Barium sulfate, an insoluble white powder, is typically used for enhancing contrast in the GI tract. Depending on how it is to be administered the compound is mixed with water, thickeners, de-clumping agents, and flavourings to make the contrast agent. As the barium sulfate doesn't dissolve, this type of contrast agent is an opaque white mixture.
A 0.5 McFarland standard is prepared by mixing 0.05 mL of 1.175% barium chloride dihydrate (BaCl 2 •2H 2 O), with 9.95 mL of 1% sulfuric acid (H 2 SO 4). [ 1 ] Now there are McFarland standards prepared from suspensions of latex particles, which lengthens the shelf life and stability of the suspensions.
Second, this same viscosity is high enough to maintain full suspension of all barium sulfate particles during the complete X-ray procedure. Third, the high charge density of the poligeenan solution (ester sulfate units) prevents caking or aggregation of the barium sulfate particles during long-term storage of ready-to-use slurry products, these ...
The barium sulfate, a radiodense (shows as white on X-ray) contrast medium, flows through the rectum into the colon. A large balloon at the tip of the enema tube may be inflated to help keep the barium sulfate inside. The flow of the barium sulfate is monitored by the health care provider on an X-ray fluoroscope screen (like a TV monitor). Air ...

The indications for enteroclysis are generally similar to small bowel follow-through. Barium suspensions such as diluted E-Z Paque 70% and Baritop 100% can be used. After that, 600 ml of 0.5% methylcellulose is administered after 500 ml of 70% barium suspension is given. Bilbao-Dotter tube and Silk tube can be used to administer barium suspension.
