{{Chemical pneumonitis}}


==Overview==
'''For patient information click [[{{PAGENAME}} (patient information)|here]]'''
Chemical pneumonitis is inflammation of the lung caused by irritation from aspirated [[vomitus]] or barium used in gastro-intestinal imaging, ingested gasoline or other [[Fractional distillation|petroleum distillate]]s, ingested or skin absorbed [[pesticide]]s, gases from [[electroplating]], or other irritants. It is sometimes called a "chemical [[pneumonia]]", though it is not infectious. May also be caused by the use of [[inhalants]].When the toxic substance is an oil, the pneumonia may be called [[lipoid pneumonia]].
==Historical perspective==
* [[Mendelson's syndrome]] is a type of chemical pneumonia in which aspiration of gastric acid is present.
* It was first described in pregnant females who aspirated gastric content during anesthesia, with development of [[respiratory distress]], [[cyanosis]] and lung infiltrates on chest Xray <ref name="pmid20993766">{{cite journal |author=MENDELSON CL |title=The aspiration of stomach contents into the lungs during obstetric anesthesia |journal=[[American Journal of Obstetrics and Gynecology]] |volume=52 |issue= |pages=191–205 |year=1946 |month=August |pmid=20993766 |doi= |url= |accessdate=2012-09-08}}</ref>.
==History & Symptoms==
* Acute onset [[dyspnea]]
* [[Cyanosis]]
* Low grade [[fever]]
* Productive cough with pink frothy sputum

===Chest XRay===
* Infiltrates on chest Xray
** Either unilateral or bilateral
** Commonly in the dependent pulmonary segment
** Dependent lobes in the upright position are the lower lobes
** Dependent lobes in recumbent position are superior segments of the lower lobes and the posterior segments of the upper lobes
