摘要： 目的研究血中乙醇质量浓度与神经行为能力的关系。方法采用中文第三版计算机化神经行为测试评价系统(NES-C3),通过自身对照的方式,对233名饮酒者进行神经行为能力的测试。结果当血中乙醇质量浓度≥0.157mg/mL时,视简单反应时和数字筛选能力指数有显著性下降;当血中乙醇质量浓度≥0.204mg/mL时,心算、视觉保留、线条判断能力指数有显著性下降。结论神经行为能力随着血中乙醇质量浓度的升高而下降,然后随着乙醇的不断代谢,血中乙醇质量浓度的降低,神经行为能力逐渐恢复。

Abstract: Objective To research the relation between blood alcohol concentration(BAC) and neurobehavioral function after drinking.Methods The neurobehavioral ability index(NAI) of 233 volunteers were measured with computer-administered neurobehavioral evaluation system-Chinese3(NES-C3).Results The NAI of simple visual reaction time and mental arithmetic declined when BAC was more than 0.157 mg/mL,the NAI of benton visual retention,length discrimination and digit cancel declined significantly when BAC was more than 0.204 mg/mL.Conclusion The neurobehavioral function declined significantly when BAC increased and recovered gradually when BAC declined due to the elimination of alcohol in blood.
