Keyword:  酒精中毒快速诊断毛细管柱气相色谱法直接进样;
Abstract: 目的建立血中乙醇的直接进样毛细管柱气相色谱法检测方法,快速诊断酒精中毒。方法血液离心后取上清液,内标溶液1∶4或1∶9稀释,直接进样,气相色谱检测,校正曲线法计算乙醇含量,根据乙醇含量诊断酒精中毒及程度。结果乙醇、异丙醇、正丁醇、异戊醇的保留时间分别为(3.43±0.01)min(n=3)、(4.63±0.01)min(n=3)、(5.83±0.01)min(n=3)和(6.80±0.01)min(n=9),血中浓度检测的校正曲线为Y=-0.32+6.45X,线性范围为5mg/100mL200mg/100mL,相关系数为0.99,最低检出浓度为1mg/100mL,69例可疑乙醇中毒或饮酒过量者中55例检出乙醇,平均血浓度为159.6mg/100mL。377例交通肇事司机199例血中检出乙醇,平均血浓度为130.0mg/100mL。结论直接进样毛细管柱气相色谱法检测血中乙醇含量具有快速、准确、操作简便、结果可靠的特点,可应用于酒精中毒诊断和酒后肇事的判定。
