对40例确诊为慢性苯中毒的患者进行脑电图检查,选取同期非苯系物作业正常体检工人40人作为对照组。结果轻度中毒与中-重度中毒组脑电图异常率明显增高,与正常对照组比较差异有统计学意义,轻度中毒与中-重度中毒间脑电图异常率差异无统计学意义;脑电图异常程度不随慢性苯中毒程度加重而加重;慢性苯中毒不同工龄组间脑电图异常率比较差异无统计学意义。 Forty patients diagnosed as chronic benzene poisoning were enrolled in the study, and 40 healthy non-benzene workers were selected as the control group. Results The abnormal rate of EEG in mild poisoning and moderate-severe poisoning group was significantly higher than that in normal control group, and there was no significant difference in EEG abnormality between mild poisoning and moderate-severe poisoning. Electrocardiogram abnormalities do not increase with the severity of chronic benzene poisoning aggravate; chronic benzene poisoning between different age groups EEG abnormalities was no significant difference.
