Chlorine gas is a known irritant of the respiratory tract, which may cause damage to various systems depending on time of exposure and concentration of the gas. Current treatments are mainly supportive. While no definitive studies have been completed to date, it has been noted that treatment with a sodium bicarbonate solution via nebulizer may lead to improved outcomes for patients dealing with chlorine gas exposure.
We present a case of a nine-year-old child arriving at the emergency department after exposure to chlorine gas. Complete recovery from his symptoms occurred rapidly with the administration of nebulized sodium bicarbonate.
Inhaled chlorine gas acts as a mucous membrane irritant, with symptoms usually beginning within minutes of exposure. Inhaled nebulized sodium bicarbonate has been suggested as a therapy for chlorine exposure. Although its mechanism of action is not well understood, it is thought that inhaled sodium bicarbonate neutralizes the hydrochloric acid formed when the chlorine gas reacts with the water in the lungs.
Nebulized sodium bicarbonate solution at a low concentration appeared to rapidly and effectively reverse the symptoms due to chlorine gas inhalation in a young child.
氯气是一种已知的呼吸道刺激物，根据接触时间和气体浓度的不同，可能会对各种系统造成损害。目前的治疗主要是支持性的。虽然迄今为止尚未完成确切的研究，但已经注意到通过雾化器使用碳酸氢钠溶液进行治疗可能会改善氯气接触患者的预后。
我们报告一例9岁儿童在接触氯气后抵达急诊科的病例。通过雾化碳酸氢钠治疗，其症状迅速完全恢复。
吸入的氯气是一种粘膜刺激物，症状通常在接触后几分钟内开始出现。吸入雾化碳酸氢钠已被建议作为氯气接触的一种治疗方法。尽管其作用机制尚不完全清楚，但人们认为吸入的碳酸氢钠会中和氯气与肺内水分反应时形成的盐酸。
低浓度的雾化碳酸氢钠溶液似乎能迅速有效地逆转幼儿因吸入氯气而出现的症状。
