目的探讨氰戊菊酯对包装工人心血管功能的亚临床影响。方法对２２名氰戊菊酯包装工和１５名无毒物接触史和无心血管疾病史的工人进行横断面调查，分析其心血管功能的改变。结果包装车间空气中氰戊菊酯时间加权平均浓度（ＴＷＡ）为０．０１７５±０．００５７ｍｇ／ｍ３（ｎ＝４），包装工皮肤平均污染量为０．５１３４±０．４２１６ｍｇ／ｃｍ２（ｎ＝６），工人接触以皮肤污染为主；症状以皮肤粘膜刺激症为主；与对照组比较收缩压升高、心率加快，收缩压与尿中ＶＭＡ明显相关，心电图检查示（Ｑ－Ｔ）ｒ值增大。结论低浓度氰戊菊酯接触对作业工人心血管功能有影响。
Objective To investigate the subclinical effects of fenvalerate on the cardiovascular function of packers. Methods A cross-sectional survey of 22 fenvalerate packers and 15 non-toxic contact history and no history of cardiovascular disease were performed to analyze the changes of cardiovascular function. Results The time-weighted average concentration of fenvalerate (TWA) was 0.0175 ± 0.0057mg / m3 (n = 4) in the air of packaging workshop, and the average skin contamination of packers was 0.5134 ± 0.4216mg / cm2 = 6). The workers were exposed mainly to skin pollution. The symptoms were mainly skin and mucous membrane irritation. Compared with the control group, systolic blood pressure increased, heart rate accelerated, and systolic blood pressure was significantly correlated with urine VMA. Electrocardiogram (Q-T) r value increases. Conclusion Low esfenvalerate exposure may affect the cardiovascular function of workers.
