What to Expect at the Emergency Room
Take the container to the hospital with you, if possible.
The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated.
The person may receive:
- Breathing support, including tube through the mouth into the lungs, and breathing machine (ventilator)
- Bronchoscopy -- camera down the throat to see burns in the airways and lungs
- Chest x-ray
- EKG (electrocardiogram or heart tracing)
- Endoscopy -- camera down the throat to see burns in the esophagus and the stomach
- Fluids through a vein (by IV)
- Medicines to relieve pain
- Skin creams to treat burns
How well someone does depends on how much carbolic acid they swallowed and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery.
Damage continues to occur to the esophagus and stomach for several weeks after the poison was swallowed. Death may occur as long as a month later.
