通过对职业性哮喘患者暴露于工作环境中和脱离工作环境后气道反应性变化的比较,研究职业性哮喘的特点以及防治对策。将患者分为脱离工作环境前和脱离工作后两组.应用非特异性支气管激发试验测定其气道反应性。以FEV_(1.0)。为评价指标,PC_(20FEV1.0)为评价标准,PC_(20FEV1.0)≥8mg/ml为正常,PC-(20FEV1.0)<8ng/ml为气道的反应性增高。结果表明,职业性哮喘患者脱离工作环境前后分别有64.0％和30.4％气道反应性增高(PC_(20<8mg/ml),两者有显著差异。结果显示职业性哮喘患者中有一定比例的病例气道反应性正常和气道的高反应性是可逆的,因此在实际工作中,加强个人防护、改进工艺流程是防止本病发生的关键,对上述患者,应尽早使其脱离工作环境,以利康复。
By comparing occupational asthma patients exposed to the working environment and from the working environment after the airway reactivity changes, to study the characteristics of occupational asthma and prevention and treatment measures. The patients were divided into two groups before and after leaving the working environment, and the non-specific bronchial provocation test was used to measure the airway responsiveness. With FEV_ (1.0). As the evaluation index, PC_ (20FEV1.0) was the evaluation standard, PC_ (20FEV1.0) ≥8mg / ml was normal, and PC- (20FEV1.0) <8ng / ml was increased reactivity of airway. The results showed that the occupational asthmatic patients had increased airway responsiveness (PC_ (20 <8mg / ml), 64.0% and 30.4%, respectively) before and after working environment, showing significant differences between the two groups Case of normal airway reactivity and airway hyperresponsiveness is reversible, so in practical work to strengthen personal protection and improve the process is to prevent the occurrence of the disease, the above patients should be removed from the working environment as soon as possible to Rehabilitation.
