Résumé :

Introduction : The hospital environment is not only occupied by the medical profession. In Senegal, the profession of surface technicians is practiced with a lack of respect for the recommended health precautions. The aim of our work was to study ventilatory disorders among cleaning staff at the Thies regional hospital. 

Material and methods : We carried out a descriptive cross-sectional study with forty cleaning agents which included a medical survey. All subjects had received a spirometric test. Obstructive syndrome was mentioned on the basis: FEV1/FVC<70% and FEV1<80% of the theoretical value. Distal obstruction has been reported on the basis of DEM25-75%˂80% of the predicted value. Restrictive syndrome was defined on the basis of a decrease in FVC<80% of the theoretical value and a FEV1/FVC ratio>95%. 

Results : The most common ventilatory disorders were isolated obstructive (47.62%) followed by mixed ventilatory disorders (38.10%). Obstructive ventilatory disorders were dominated by total obstruction of the bronchi (63.89%). Isolated obstructions, as well as mixed ventilatory disorders, were significantly higher in women compared to men (p=0.045 and p=0.051 respectively) with a sex ratio of 0.35. Tobacco was significantly involved in altering functional parameters.  A significant increase in mixed syndrome was noticed in the 5-10 year old group (35% of cleaning workers with less than 5 years of service compared to 50% of 5-10 year old workers). After 10 years of exposure, we have observed a significant increase in functional restriction. The use of a beta-2-mimetic bronchodilator revealed spirometric data in favor of asthma in 4.76% of our subjects. 

Discussion/conclusion : The cleaning activity, particularly in hospitals, causes significant ventilation disorders.
