Abstract

The pressures generated by a barium suspension and various solutions of meglumine sodium diatrizoate in water were measured with a manometer. A pressure of 120 mm Hg was produced by a 3.5-foot (105-cm) column of 60% wt/vol barium and a 5-foot (150-cm) column of either a 1:3 or 1:4 solution of meglumine sodium diatrizoate and water. This is the pressure used to reduce an intussusception with air.
