THE IMPACT OF WORKING CONDITIONS ON INDICATORS OF CARDIORESPIRATORY SYSTEM AND BLOOD IN ELECTRIC WELDERS WITH DIFFERENT LENGH OF WORK

Abstract

Production environment as part of the individual's environment consists of the natural-climatic factors and the conditions related to professional activities, which under certain conditions can be harmful. The purpose of the study was to investigate the impact of harmful workplace factors on the organism of a welder. Methods. The characteristic of the sanitary and hygienic working conditions of the welders was given. Parameters of welders' external respiration were identified using a complex of monitoring cardio-respiratory system and tissues hydration. The indices of peripheral blood (erythrocytes number, hemoglobin content, erythrocyte sedimentation rate, functional state of the cardiovascular system (electrocardiogram, the values of systolic and diastolic blood pressure) and the state of bronchopulmanory ways (according to spirographic and x-ray surveys) were studied. Changes of physiological parameters in workers exposed to health hazards, depending on their length of service and age were indicated. Results. The study results revealed that with increase in work experience of welders, number of people suffering from respiratory diseases, diseases of the musculoskeletal system and myocardial dystrophy also increased. Welding aerosol with high content of manganese and iron is the cause of professional pathologies development such as pneumoconiosis and dust bronchitis. The analysis of welders' working conditions revealed that the main harmful production factor was the welding aerosol. The workers had an increase in the erythrocyte sedimentation rate, reduction of red blood cells quantity and hemoglobin, neutrocytosis, which might indicate the reduced resistance of the organism and the development of the inflammatory process. Myocardiodystrophy was detected which is characterized by increased blood pressure, complaints of heart stabbing and aching pain, asthenia, fatigability. Conclusion. The results indicate the necessity to carry out routine health screening of the welders at least once a year, as well as preventive and curative interventions aimed at health improvement.
