摘要 目的:探讨外周血纸片法筛查儿童铅中毒临床推广应用价值,总结血铅检测和降低儿童血铅水平的方法.方法:采用上海第二医科大学儿童铅中毒防治研究中心提供的血铅检测专用试纸,测试结果阳性为高血铅即铅中毒,同时采静脉血2ml用石墨炉原子吸收光谱法进行血铅测定,血铅≥100μg/L为高血铅即铅中毒,对铅中毒儿童及时进行个体干预,3个月后复查血铅水平.结果:受检儿童1168例,纸片法阳性者802例,占68.7%,石墨炉法高血铅者774例,占66.3%,两种检测方法比较无显著性差异(P>0.05).3~6岁为铅中毒高发年龄,铅中毒儿童干预治疗后血铅水平均有下降.结论:外周血纸片法筛查儿童铅中毒操作简单,价廉,测试结果具有临床参考价值.及早干预可最大限度降低铅的毒性作用.
