Your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.
This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.
What to Expect at the Emergency Room
Take the container with you to the hospital, if possible.
The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure.
Tests that may be done include:
- Bronchoscopy: camera down the throat to see burns in the airways and lungs
- Chest x-ray
- ECG (electrocardiogram), or heart tracing
- Endoscopy: camera down the throat to see burns in the esophagus and the stomach
- Medicine to treat symptoms
Treatment may include:
- Fluids through the vein (by IV)
- Washing of the skin (irrigation), perhaps every few hours for several days
- Tube through the mouth into the stomach to wash out the stomach (gastric lavage)
- Surgery to remove burned skin
- Breathing support, including tube through the mouth into the lungs, and breathing machine (ventilator)
How well someone does depends on how severe their poisoning is and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery.
Damage can continue to occur for several weeks after swallowing lighter fluid.
