Injuries caused by thermal trauma more and more often affect people and they are an important problem of contemporary medicine. It is connected with the civilization development. Burn concerns not only the exterior integuments of the body but also airways, in those cases, the death rate among those who were injured with the thermal trauma increases. The treatment of both the burns and their complications is a long-lasting process, involving many specialists of various disciplines, and not always does it bring the wanted effects. The aim of the study was the assessment of the late morphological sequels inside the larynx and ventilation efficiency as a result of thermal inhalation trauma in the airways of the coal miners after the methane explosion. The methodology of examinations consisted of subjective evaluation of ventilation efficacy by MRC scale and ventilating rate measurement FEV1, FVC, FEV1%, PEF, MEF50, PIF, MIF 50, FIV. The morphological larynx evaluation was conducted based on videolaryngoscopy. 23 injured coal miners, who had been burnt at work in coal mines in 2003 in the methane explosion, were put under scrutiny. All the above mentioned examinations were done to the study group, but also to the specially selected control group, 23 coal miners. During the ventilating rates analysis in the study group, their lower values were noticed in comparison to the control group, however, the values were still within the clinical norms. Videolaryngoscopy showed hypertrophy of the laryngeal tissues.

The job as a coal-miner exposes to the greatest risk. One of the most dangerous health hazard is a burn/inhalation injury during the methane explosion. The victims undergo physical trauma, effect of high temperature and inhalation of toxic gases and products of incomplete combustion, As a result of inhalation injury both, upper and lower airways are affected. The aim of the study was to analyse the relationship between burn/inhalation injury and quality of voice in affected coal-miners. A group of 23 patients (men) in age from 28 to 59 (mean 38.5) 3 years after burn/inhalation injury participated in this study. The voice evaluation based on ENT examination, videlaryngostroboscopy, acoustic analysis, MPT parameter and GRBAS analysis was performed. The special control group of coal-miners served as a control. On the basis of the subjective evaluation and the objective acoustic analysis, aerodynamic parameter and videlaryngostroboscopy the worse quality of voice in the group of injured coalminers was shown in comparison to the control group. No substantial correlation between the acoustic parameters, MPT parameter and ventilating rates was found.

Streszczenie: W rozdziale zaprezentowano przedsiębiorstwo produkujące konstrukcje spawane dla maszyn, m.in. wysięgniki. Krótko przedstawiono wysięgnik oraz jego proces wytwórczy. W części badawczej zaprezentowano użycie dwóch tradycyjnych narzędzi zarządzania jakością: diagramu Ishikawy i diagramu Pareto-Lorenza. Diagram Ishikawy zastosowano w celu identyfikacji grup przyczyn mogących wpływać na niezgodności wysięgnika, natomiast diagram Pareto-Lorenza stworzono, aby zbadać, które niezgodności wysięgnika występują najczęściej i które należy wyeliminować w pierwszej kolejności. W części badawczej zaprezentowano również praktyczne zastosowanie metody FMEA, za pomocą której zidentyfikowano potencjalne niezgodności wysięgników, a także określono liczby priorytetowe i zaproponowano działania zapobiegawcze i korygujące.
