영문 초록

Objectives：The aim of this study was to evaluate the interreliabilities and reproducibilities of two breathanalyzers which commonly used in clinical settings, research fields, and legal purposes including roadside testing. Methods：Thirty-four healthy male volunteers were examined through 30, 60, 90, 120, 150 and 180 minutes after 20 minutes’ intake of one of the two doses of alcohol (0.5 and 0.75 g/kg of body weight) on separate occasions. Two kinds of breathanalyzers [Alco- Sensor Ⅳ (Intoximeters, Inc., USA；Alco-Sensor) and Lion Alcolmeter SD-400P (Lion Laboratories plc, UK；SD-400P)] were used to measure the breath alcohol concentrations (BrAC). Duplicate breath samples at each time point were used to determine the repeatabilities of the breathanalyzers. Results：Mean values of two breathanalyzers at each time point were not statistically different. Although there were not significant, the values obtained from SD-400P were tended to slightly higher than those of Alco-Sensor. Inter-reliabilities of Alco-Sensor and SD-400P at 0.5 and 0.75 g/kg of body weight were very high[r＝0.972 (p<.001)；r＝ 0.938 (p<.001), respectively]. Test-retest reliabilities of Alco-Sensor and SD- 400P were also very high[r＝0.976 (p<.001)； r＝0.984 (p<.001), respectively]. Conclusion：The two breathanalyzers can be used as highly reliable instruments in all kinds of fields including roadside testing. Although further studies concerning the accuracy and precision of the breath-alcohol measurements in Koreans should be done, it suggests that these instruments may be easily and safely used as evidential breath testing.
