COMPARISON OF CARBOXY-METHYLCELLULOSE, TANNIC ACID AND NO ADDITIVE IN BARIUM EXAMINATIONS OF THE COLON

CARLOS A. PEREZ M.D.1 and MARVIN J. FRIEDENBERG M.D.1

1 From the Edward Mallinckrodt Institute of Radiology, Washington University School of Medicine, St. Louis, Missouri

Laboratory tests were made to evlauate the viscosity, stability, settling properties, and adhesiveness of USP barium sulfate, barium suspensions with 0.2, 0.5 and 1.0 per cent carboxy-methylcellulose, and of barium suspensions with 0.25 per cent tannic acid added. The postevacuation roentgenograms of 1,000 barium enema examinations were compared, 200 examinations being performed with each of these 5 barium mixtures. The results show that 1.0 per cent carboxy-methylcellulose has a comparable stabilizing effect in barium suspensions and enhances mucosal coating equally as well as a 0.25 per cent concentration of tannic acid, without the possible undesirable toxic reactions of high concentrations of the latter, and that both are preferable to lower concentrations of carboxy-methylcellulose.

Further investigation is necessary to continue improving the suspension of barium mixtures.
