Objective To determine the factors associated with death in poisoning victims by carbamate ("Chumbinho"). Method Retrospective study, epidemiological case-control based on poisoning reporting forms, a poison control center located in the metropolitan region of Rio de Janeiro. We used 24 notification forms of poisoning in men aged 20 to 59 years with poisoning by carbamate history from 2005 to 2009. The records were randomly selected, respecting the ratio 1:3 (a case to three controls). The age range was 23-58 years, average 43.83 years. Results The most frequent symptoms were myosis (OR=1.0; 95% CI: 0.27 to 3.69 p=1.0.), drooling (OR=0.83; 95% CI. 0.22 to 3.12 p=0.78), and dyspnea (OR=0.66; 95% CI: 0:14-3.03 p=0.59). Conclusion The deaths were associated with drooling, miosis and dyspnea and a strong association with pulmonary rales, bronchospasm and pulmonary snoring.
