Hydrocarbon pneumonia is caused by drinking or breathing in gasoline, kerosene, furniture polish, paint thinner, or other oily materials or solvents. These hydrocarbons have a very low viscosity, which means that they are very, very thin and slippery. If you tried to drink these hydrocarbons, some would likely slip down your windpipe and into your lungs (aspiration) rather than going down your food pipe (esophagus) and into your stomach. This can easily happen if you try to siphon gas out of a gas tank with a hose and your mouth.
These products cause fairly rapid changes in the lungs, including inflammation, swelling, and bleeding.
Pneumonia - hydrocarbon
Symptoms may include any of the following:
Those with mild symptoms should be evaluated by doctors in an emergency room, but may not require a hospital stay. The minimum observation period after inhalation of a hydrocarbon is 6 hours.
People with moderate and severe symptoms are usually admitted to the hospital, occasionally to an intensive care unit (ICU).
Hospital treatment would likely include some or all of the interventions started in the emergency department.
Most children who drink or inhale hydrocarbon products and develop chemical pneumonitis recover fully following treatment. Highly toxic hydrocarbons may lead to rapid respiratory failure and death. Repeated ingestions may lead to permanent brain damage (including memory, attention and judgment deficits, chronic confusion, dementia and psychiatric problems), liver damage, and other organ damage.
Complications may include any of the following:
If you know or suspect that your child has swallowed or inhaled a hydrocarbon product, take them to the emergency room immediately. DO NOT use ipecac to make the person throw up.
If you have young children, be sure to identify and store materials containing hydrocarbons carefully.
