In our institute, we took measures such as making the original manual and co-medical stuffs education to prevent barium aspiration before using high-density, low-viscosity barium from March 2003. We checked 57, 773 persons who had undergone upper gastrointestinal series from April 2003 to March 2005, and found 14 persons who aspirated barium. The aspiration rate was 0.024%, the mean age was 53 years old, and the range was 35-80. The older group aspiration rate (over 65 years old) was 0.050%, and that of younger group was 0.021%. But there was no significance.<BR>The aspiration rate in the nursing-home was remarkably high than others (in nursing-home: 0.82% others: 0.018% p<0.05) from April 2003 to March 2004. For the purpose of decreasing the aspiration rate in the nursing-home, we added the other preventive measures such as using the paper cup with cut so as not to strike nose when leaning it and so on. After these new measures, the aspiration rate in the nursing-home became 0.43%. And it was reported that using high-density, low-viscosity barium improved accuracy in indirect radiography, but the aspiration rate rose. We think there is a possibility that aspiration rate can be decreased by taking preventive measures.
