Abstract

Chemical pneumonitis is caused by the inhalation of noxious chemical substances and is a cause of occupational lung disease. Nitric acid, which is a one of the common air pollutants and a potential oxidant for refining and cleansing of metals, has a chance for occupational and environmental exposure. A 52-year-old man visited our hospital due to coughing and dyspnea after the inhalation of nitric acid fumes at his workplace. He had conditions of tachypnea (respiratory rate 26 /min) and hypoxemia ($PaO_2$ 42.6 mmHg, $SaO_2$ 80.2% in room air) in our emergency department. The chest radiographs showed diffuse interstitial infiltrates and ground glass opacity in both lungs. The patient made improvements in clinical symptoms and chest radiography after being given a supply of oxygen, antibiotics, and bronchodilator therapy without systemic glucocorticoid therapy. On his follow up visit after 4 weeks, he showed no symptoms and sequelae, and the pulmonary function test showed a normal pulmonary function.

유독성 물질의 흡인은 화학성 폐렴을 유발하며 이는 직업성 폐질환의 한 원인이다. 질산은 흔한 대기 오염물질의 한가지이고 작업장에서 사용되는 강력한 산화제로 직업적 노출의 가능성이 있다. 52세 남자 환자가 질산을 이용한 에어컨 도관 세척작업 중에 발생한 증기의 흡입 후 기침, 호흡곤란을 호소하며 병원에 방문하였다. 내원 당시 호흡수 분당 26회였고, 산소 투여 없이 시행한 동맥혈 가스분석에서 $PaO_2$ 42.6 mmHg, $SaO_2$ 80.2%로 저산소혈증이 나타났으며, 흉부 방사선 검사에서 양측폐야에 미만성 폐침윤과 젖빛유리 음영이 나타났다. 환자는 전신적인 스테로이드를 사용하지 않고, 보존적인 치료만으로 입원 2일째부터 임상적인 증상과 방사선 사진의 호전이 있었고 퇴원 후 폐기능의 손상 없이 호전되었기에 이를 보고하는 바이다.
