Abstract
Objectives:Chlorine gas is a potent pulmonary irritant that affects the mucous membranes and induces severe disturbances of pulmonary gas exchange within minutes of inhalation. The present study evaluated an extraordinary type of mass inhalational exposure.Material and Methods:Clinical reports of 25 soldiers who were admitted to the emergency department of Maresal Cakmak Military Hospital, Erzurum were retrospectively evaluated. All patients were exposed to chlorine gas as a result of mixing sodium hypochlorite with hydrochloric acid during cleaning activities.Results:All patients were male and the mean age of patients was 22.04 ± 2.98 years. The main symptoms were coughing and dyspnea in 18 patients (72%). Forced expiratory volume in 1 second (FEV1) and FEV1/forced volume capacity (FVC) ratio were found to be normal in all patients but FVC and peak expiratory flow (PEF) were below the normal range (80%) in 9 patients (36%). All patients received warmed humidified oxygen combined with nebulized salbutamol. Inhaled budesonide and nebulized sodium bicarbonate were ordered additionally for 19 patients (76%). Thirteen patients (52%) were discharged from the emergency department and 12 patients (48%) were hospitalized. No mortality was observed.Conclusion:Chlorine gas is a potent pulmonary irritant that causes acute damage in both the upper and lower respiratory tract. We suggest that inhaled steroids combined with nebulized sodium bicarbonate could be a safe and effective alternative for the treatment of symptomatic patients. Education of the public about the dangers of mixing of hypochlorite bleach with acidic cleaning agents is also very important.
