Transcript

  • 1. Study of Pulmonary Function in Cement Factory workers (Diamond Cement Company, Madora, Jhansi) Presented By : Dr. Awadhesh kumar sharma Department of Medicine M.L.B. Medical College, Jhansi
  • 2. INTRODUCTION Occupational lung disease are those conditions for which environmental or occupational causes are suspected. This assessment is important because removal of the patient from harmful exposure is often the only intervention that might prevent further significant deterioration or lead to improvement in patients condition.
  • 3. In a study, population over age 15, 15-20% of burden of Asthma and COPD has been estimated to be due to occupational factors. In cement factory workers, they are exposed to particles like silica, Mg, Zn, Al. These particles are of 2.5-10  m range and mostly deposited relatively high in the tracheo Bronchial tree.
  • 4. <ul><li>Determinant of disease occurrence among exposed persons. </li></ul><ul><li>Size of particle </li></ul><ul><li>Solubility of gases </li></ul><ul><li>Chemical composition </li></ul><ul><li>Mechanical properties </li></ul><ul><li>Immunogenicity </li></ul><ul><li>The application of test of lung function on cement workers assess the effect of exposure of known hazard on them and this study shows correlation between exposure and disease occurrence . </li></ul>
  • 5. AIMS AND OBJECTIVES To evaluate the effect of cement exposure on ventilatory function of workers in Diamond cement factory at Madora, Jhansi.

  • 8. MATERIAL AND METHODS The present study is carried out in department of Medicine M.L.B. Medical College, Jhansi, to evaluate the effect of cement exposure among cement factory workers. For this study workers of cement factory were taken as subjects and normal healthy attendants of patients were taken as control. 136 cement factory workers were selected randomly and enrolled.
  • 9. <ul><li>Spirometry was performed on spiroexcel PC based PFT machine in sitting posture with application of nasal clip. The following parameters were recorded. </li></ul><ul><li>FVC </li></ul><ul><li>FEV 1 </li></ul><ul><li>FEV 1 /FVC </li></ul><ul><li>PEFR </li></ul><ul><li>FEF 25%-75% </li></ul>

  • 12. All the subjects underwent extensive clinical and physical examination. STUDY GROUP 30 workers were excluded because of there <10 years duration of work in cement factory and 6 were excluded because there age was > 60 years. So the final study group constitute 100 workers. Among the 100 workers 60 were non smokers and 40 were smokers.
  • 13. STUDY GROUP CONTROL GROUP 100 50 Smoker Non Smoker 60 40
  • 14. After all inclusion / Exclusion criteria the final study group constituted – Study group Group A Smokers (40) Group B Non Smokers(60) Control group 50
  • 15. OBSERVATION Change in FVC as per study group of cases When mean values of FVC were compared individually with mean value of control (4.2±0.06), a highly significant (p<0.001) decline in group A and significant decline in group B (p<0.01) were seen in both groups as compared to control group. Smokers Non smokers 3 3.5 4.2
  • 16. When mean values of FEV 1 were compared individually with mean value of control (3.42±0.32), a insignificant decline (p>0.05) were seen in both groups as compared to control group. Change in FEV 1 (litre) as per age group Smokers Non smokers 2.2 2.5 3.42
  • 17. When mean values of FEV 1 /FVC were compared individually with mean value of control (83.36±0.16), a insignificant decline (p>0.05) were seen in both groups as compared to control group. Changes in FEV 1 / FVC (% ) as per study group Smokers Non smokers 86 90 83.3
  • 18. When mean values of PEFR were compared individually with mean value of control (7.90±0.30), a significant decline (p<0.01) were seen in both groups as compared to control group. Changes in PEFR (litre/sec) as per study group Smokers Non smokers 4.89 5.06 7.9
  • 19. When mean values of FEF25%-75% were compared individually with mean value of control (3.21±0.062), a significant decline (p<0.01) were seen in both groups as compared to control group. Changes in FEF25%-75% (litre/sec) as per study group Smokers Non smokers 2.1 2.42 3.21
  • 20. <ul><li>CONCLUSION </li></ul><ul><li>The following conclusion were drawn from the study. </li></ul><ul><li>When Group A (smokers) was compared with controls the parameters FVC shows highly significant decline (p<0.001), FEF25%-75%, PEFR shows significant (p<0.01) decline in mean value of above two parameters and insignificant changes seen in parameter FEV1/FVC and FEV1 (p>0.05). </li></ul>
  • 21. <ul><li>When Group B (non smokers) was compared with controls the parameters FVC, FEF25%-75% and PEFR shows significant decline in mean value of above parameters and insignificant changes in parameter FEV1/FVC and FEV 1 (p>0.05). </li></ul>In the view of above observations we conclude that the ventilatory functions were impaired more in the persons exposed to cement particles and smoking increases the impairment of ventilatory function.
  • 22. <ul><li>This study shows that cement workers are at increased risk of respiratory diseases. Factory management should take proper initiative to prevent or decrease such conditions because once the disease occurs then there is no cure for it. The best may be to decrease the incidence by taking proper preventing measures </li></ul><ul><li>Medical Measures </li></ul><ul><li>Engineering measures </li></ul>
