RESUMO
Salbutamol is a short-acting agonist of the ß(2) adrenergic receptors sometimes misused or abused, which can result in various cardiovascular adverse effects. We report one case of fatal salbutamol misuse or abuse in a 36-year-old poorly controlled female asthmatic patient with a past medical history of alcoholism and a recent smoking cessation. She died shortly after hospital admission following acute dyspnea and sudden collapse at home. Toxicological analyses evidenced salbutamol overdose, and necropsy showed acute lung edema and marked dysplasia of the right ventricle and revealed the patient was pregnant. The involvement of an initial disorder of the ventricular rhythm leading to cardiac failure is suggested by the presence of several combined pro-arrhythmogenic factors, such as arrhythmogenic right ventricle dysplasia, hypoxemia related to bronchospasm and salbutamol overdose.

A rational medical, occupational and toxicological approach is instrumental to select objectively among pregnant women exposed to chemicals at the workplace those who should be withdrawn or benefit from improvements of working conditions. Risk assessment is based on a comprehensive review of compounds' hazards and a thorough evaluation of the actual exposure including biomonitoring whenever as possible. Since 1996, the Lyon Poison Center has been conducting a prospective follow-up of pregnant women exposed to chemicals at the workplace. Of these, 206 exposed to organic solvents since conception were selected and matched with 206 exposed to a non-embryotoxic agent. Total withdrawal from the workplace was recommended in 22% of cases, but exposure was not considered to be hazardous to pregnancy in 51%. Overall, no increase in adverse outcomes was found. Maintaining pregnant women at their workplace, particularly most of the laboratory technicians, is reasonably possible after careful toxicological risk assessment.
