0099 Changes in ventilatory and haemodynamic parameters during exposure to ultrafine particles in a manufacturing farm machinery

Abstract

OBJECTIVES: To evaluate the influence of occupational exposure to ultrafine particles on cardiopulmonary parameters. METHOD: Changes in ventilatory and haemodynamic parameters during occupational exposure to ultrafine particles summers studied using a survey-type retrospective cohort exposed unexposed conducted in a company producing agricultural equipment for a period of five month period from January 1 to May 30, 2013 in 139 subjects, including 107 exposed men and 3 unexposed. The survey consisted of a questionnaire (WHO), a complete physical examination with measurement of blood pressure before and after the job, a spirometer before and after the job. RESULTS: 18.7% were presented, a type of respiratory symptoms in chronic bronchitis against only 6.3% of non-exposed with a statistically significant difference (P = . 04). The prevalence of chronic bronchitis was significantly higher in smokers than in nonsmokers with 23.3% against 7.6% respectively. (P = . 01). The papers have a higher incidence of lung disease than unexposed with 83.2% of restrictive lung disease after exposure in exposed against 78.1% in the unexposed. Smokers with normal spirometry is less than non-smokers before and after exposure with the following frequencies after exposure: 12.1% in non-smokers against only 4.1% in smokers. On haemodynamic parameters was noticed an increase in TAP (47.87 mmHg), FC (76.16 mm Hg) after exposure in exposed. CONCLUSIONS: Our results have demonstrated the harmful effects of ultrafine particles on changes in ventilatory and haemodynamic parameters.
