What to Expect at the Emergency Room
The health care provider will measure and monitor vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. The person may receive:
- Activated charcoal
- Airway support, including oxygen, breathing tube through the mouth (intubation), and breathing machine (ventilator)
- Blood and urine tests
- Chest x-ray
- EKG (electrocardiogram, or heart tracing)
- Fluids through a vein (IV)
- Medicines to treat symptoms
People who still have symptoms after 6 hours of treatment may need to be admitted to the hospital.
How well the person does depends on the amount of poison swallowed and how quickly treatment was received. With proper treatment, people can recover in 1 to 5 days. If the person was in a coma or in shock long-term (causing damage to many internal organs), a more serious outcome is possible.
