The presence of volatile compounds, such as acetone, acetaldehyde, methanol, ethanol, isopropanol, and n-propanol, in the blood of 169 acutely poisoned alcoholics was determined. The clinical diagnosis of addiction was made on the basis of a patient interview as well as physical, psychological, and psychiatric examination. At the time of the patients' admission to the clinic, the mean concentration of ethanol in blood was 3.14 +/- 1.10 g/l and its elimination rate in the studied group was 0.27 +/- 0.08 g/kg/h, an elimination rate significantly higher (P < .001) than that of social drinkers, which averages to 0.014 +/- 0.04 g/kg/h. The presence of other volatile compounds in the blood of alcohol-addicted patients is common. The calculated elimination rate constant of methanol was about 0.2 h(-1). This rate seems to indicate that, in heavy drinkers, the elimination of methanol may be relatively fast even if the ethanol concentration is above I g/l. The elimination of other volatile compounds can be accelerated by large doses of ethanol, although it is not con-elated with actual blood ethanol level. Moreover, in most of the blood samples with a methanol concentration below 10 mg/l, the measured concentration of acetone was below 7 mg/l and that of isopropanol was below 2 mg/l.
