[Otoneurologic and cardiovascular abnormalities associated to carbon monoxide poisoning in occupational exposed workers].

Background: Even though Federal Labor Law includes carbon monoxide poisoning in the list of occupational diseases, the registration of this intoxication rarely occurs in a work environment. The objective was to determine the association of this poisoning with cardiovascular and otoneurologic disorders, in order to establish adequately this diagnosis as a work-related illness.

Methods: Cross-sectional survey performed in a group of broiler production workers, compared with a control group (n = 54).
