目的 探讨重庆地区驾驶员血液中乙醇浓度 (BAC)和驾驶能力的关系 ,为交通安全立法提供科学依据。 方法 随机选择重庆地区 59名驾驶员志愿者 ,建立饮酒后驾车模型、科学的BAC测定以及驾驶能力评价体系 ,对不同BAC下驾驶能力进行测评。 结果 受试者出现驾驶能力损害时的BAC均数为 685.9mg/L ,最小值 190 .0mg/L ,最大值 152 0 .0mg/L ,总体均数 95%可信区间为 60 2 .4～ 70 9.5mg/L。汉族和土家族间、汉族男性和女性间、2 3～ 3 5岁和 3 6～ 56岁年龄组间差异无显著性意义 (P >0 .0 5) ,而既往饮酒量不同的三个组别间差异有显著性意义 (P <0 .0 5)。随着BAC增高 ,驾驶能力受损人数增加。在 2 0 0 .0mg/L有 3 % (2 / 59)的受试者驾驶能力降低 ,80 0 .0mg/L则达到 68% (40 / 59)。 结论 随着BAC增高 ,重庆地区驾驶员驾驶能力受损人数比例增加 ,出现驾驶能力明显损害时BAC为 60 2 .4～ 70 9.5mg/L ,既往酒量较大人群中该值较高
Objective To explore the relationship between driver ’s blood ethanol concentration (BAC) and driving ability in Chongqing and to provide a scientific basis for traffic safety legislation. Methods A total of 59 driver volunteers in Chongqing were selected randomly to establish a driving model after drinking, a scientific BAC test and a driving ability evaluation system to evaluate the driving ability under different BACs. Results When the driving ability of subjects was impaired, the BAC mean was 685.9 mg / L, the minimum value was 190.0 mg / L, the maximum value was 152.0 mg / L, the overall average 95% confidence interval was 60 2 .4 ~ 70 9.5 mg / L. There was no significant difference between Han and Tujia ethnic groups, Han nationality male and female, between 23 and 35 years old and between 36 and 56 years old (P> 0.05), while the former three groups There was a significant difference between the two groups (P <0.05). As BAC increases, the number of impaired driving ability increases. Driving ability was reduced in 3% (2 of 59) subjects at 200 mg / L and 68% (40/59) at 80 0 .0 mg / L. Conclusions With the increase of BAC, the proportion of driving ability impaired in Chongqing increased, and the BAC was 60.2-4-70.5mg / L when the driving ability was significantly impaired. This value was higher in the previous large-volume drinkers
