200例职业性铅中毒患者肝脾B超检查结果分析

Analysis of examination results of liver and spleen B ultrasound in 200 patients with occupational lead poisoning

目的：了解长期接触铅所致慢性铅中毒患者肝脾的B超征象。方法选择2008~2012年在本院门诊或住院的200例职业性慢性铅中毒患者为观察组，无职业病危害因素接触的公务员200例为对照组，两组均给予肝脾B超检查并对其检查结果进行比较分析。结果观察组的肝脾B超异常率为23.5%，明显高于对照组的11.5%（P〈0.01）；观察组的肝大检出率为16%，明显高于对照组的6%（P〈0.01）；观察组的左肝长、厚，右肝斜厚均高于对照组（P〈0.01）。结论职业性慢性铅中毒患者肝脾存在一定的损害，应引起重视。

Objective To understand the signs of liver and spleen B ultrasound in patients with chronic lead poisoning caused by long-term lead exposure. Methods 200 patients with occupational chronic lead poisoning in outpatient de-partment or hospital from 2008 to 2012 were selected as the observation group,200 civil servants who were not exposed to any occupational risk factors were selected as the control group.The two groups received liver and spleen B ultra-sound and the results were compared and analyzed. Results Abnormal rate of liver and spleen B ultrasound in the ob-servation group （23.5%） was significantly higher than that in the control group （11.5%） （P〈0.01）;detection rate of hep-atomegaly in the observation group （16%） was significantly higher than that in the control group （6%） （P〈0.01）;detec-tion rate of length and thickness of left liver and oblique thickness of right liver in the observation group were higher than those in the control group （P〈0.01）. Conclusion Liver and spleen of patients with occupational chronic lead poi-soning have a certain degree of damages and it needs to be attached great importance.
