目的评估某电子企业酸碱作业工人的肺功能状况。方法对2 224例酸碱作业工人的肺功能检测结果进行分级评定和内外对照。结果通气功能减退率和小气道功能异常率分别为22.66%和10.21%(P<0.01)。通气功能轻、中和重度减退率分别为21.72%、0.90%和0.04%;小气道功能轻、中和重度异常率分别为8.72%、1.35%和0.13%。酸碱作业工人的通气功能减退率和小气道功能异常率与粉尘作业工人的差异均无统计学意义(P>0.05);酸碱作业工人的通气功能减退率与整群抽样的垃圾处理工人的差异无统计学意义(P>0.05),但高于整群抽样的粉尘作业工人、打磨作业工人及电焊作业工人(P<0.01);小气道功能异常率与整群抽样的垃圾处理工人、粉尘作业工人、打磨作业工人及电焊作业工人的差异均无统计学意义(P>0.05)。结论该电子企业酸碱作业工人肺功能损害较严重,应加强对该人群的肺脏健康监测和职业卫生防护。
Objective To assess the lung function of acid-base workers in an electronics company. Methods The pulmonary function test results of 2 224 acid-base workers were graded and compared internally and externally. Results The rates of ventilatory dysfunction and small airway function were 22.66% and 10.21% respectively (P <0.01). Ventilatory function of light, moderate and severe reduction rates were 21.72%, 0.90% and 0.04%; small airway function light, moderate and severe abnormal rates were 8.72%, 1.35% and 0.13%. There were no significant differences in the rate of ventilatory dysfunction and the abnormal rate of small airway function between the acid-alkali workers and the dust-exposed workers (P> 0.05). The rate of ventilatory dysfunction in acid-base workers was significantly lower than that of the garbage workers There was no significant difference between the two groups (P> 0.05), but higher than those of dust sampling workers, polishing workers and welding workers in cluster sampling (P <0.01) There was no significant difference between working workers, grinding workers and welding workers (P> 0.05). Conclusion The electronic company acid-base workers lung function damage is more serious, should strengthen the population of lung health monitoring and occupational health protection.
