Abstract

There are many methods of treatment of the intussusception in children, including surgery, barium reduction,air reduction, and saline enema under ultrasonograhic monitoring. Among them, barium reduction and air reductionhave been used widely as nonsurgical method of treatment in radiologic department. During barium reduction, the bottle filled with barium solution must not be elevated over a 3 feet from the operating table. In air reduction, diagnostic pressure is about 60 mmHg and pressure during reduction usually is maintained between 90 mmHg and 130 mmHg. The authors have studied about pressure difference of barium solution by changing height of the bottlefilled with barium solution, and have compared with pressure in air reduction. The results are as follows: 1.Pressure of 20 w/v % barium solution at the 60 cm height is 44.4 mmHg, and 69.6 mmHg at the 90 cm height. 2. Pressureof 40 w/v % barium solution at the 60 cm height is 51.4mmHg, and 80.1 mmHg at the 90 cm height. 3. Pressure of 40w/v % barium solution at the 90 cm height is much lower than the pressure maintained during air reduction, and this difference in pressure may be one of the causes of low reduction rate in barium reduction than air reduction. 4. The pressure gradient per 10 cm height is about 8.45 mmHg in 20 w/v % barium solution, about 9.21 mmHg in 30 w/v %barium solution, and about 9.72 mmHg 40 w/v % barium solution. 5. Intraluminal pressure difference between thebarium reduction and the air reduction is probably one of the major causes of rapid diagnosis and high reductionrate in the air reduction.
