Description

混合粒子型硫酸バリウム｢バリトゲンHD｣の懸濁液最適濃度について,検討を行った｡懸濁液安定性は,200w/v%と190w/v%は良好であったが,180w/v%は不良で臨床使用には不向きであると思われた｡臨床的評価において200w/v%と190w/v%は付着性,辺縁の描出能,胃小区描出能においては同程度であった｡200w/v%に多く見られた凝集･ムラ付き,気泡は,190w/v%では少なくなった｡飲み易さは,200w/v%,190w/v%とも飲み易いと評価されたが,190w/v%でより飲み易い傾向にあった｡バリトゲンHDの最適懸濁液濃度は,190w/v%であると思われる｡

Barium sulfate suspensions in 200w/v% and 190w/v% had good stability. But in 180w/v% it had worse stability. Significant difference was not observed in coating, visualization of gastric margin and gastric area between in 200w/v% and 190w/v%. Barium sulfate suspensions in 190w/v% had less sticky coating of gastric mucosa and fewer bubbles than 200w/v%. Barium sulfate suspensions in 190w/v% was easiest density to drink. 190w/v% seems to be most adequate density in our study.
