Ventilatory Functions, Oxygen Saturation, and Quality of Life Response to Long Time Cement Dust Exposure

Completed

• Conditions: Occupational Diseases
• Interventions: Diagnostic Test: questionaire and ventilatory function test

• Registration Number: NCT05047497
• Lead Sponsor: Cairo University

Brief Summary

Thousands of people are working daily in a dusty environment. Many studied reported respiratory symptoms and ventilatory disorders among Factory workers who exposed to cement dust. But the evidence for respiratory effect and daily activities over a long time of cement dust exposure has not been conclusive

Detailed Description

A total of 49 subjects working in a cement production factory were assessed and divided into three groups according to the total period of work exposure. Groupe A (18 subjects) with work period \< 10 years, group B (13 subjects) with work period 10-15 years, group C (18 subjects) with work period \> 15 years. The ventilatory functions, oxygen saturation, and quality of life were assessed in the three groups. RESULTS: The study results revealed a statistically significant difference between the three groups in the mean values of FVC (%), FEV1/FVC (%), SPO2.
