Before Calling Emergency

Have this information ready:

Poison Control

Your local poison control 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 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.

Also, you can call the National Button Battery Ingestion Hotline (800-498-8666).

What to Expect at the Emergency Room

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:

If the battery has passed through the stomach into the small intestine, the usual treatment is to do another x-ray in 1 to 2 days to make sure the battery is moving through the intestines.

The battery should continue to be followed with x-rays until it passes in the stool. If nausea, vomiting, fever, or abdominal pain develop, it may mean that the battery has caused a blockage of the intestines. If this happens, surgery may be needed to remove the battery and reverse the blockage.

Outlook (Prognosis)

Most swallowed batteries pass through the stomach and intestines without causing any serious damage.

How well someone does depends on the type of battery they swallowed and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery.

Burns in the esophagus and stomach may result in ulcers and fluid leakage. This can lead to serious infection and possibly surgery. Complications become more likely the longer the battery is in contact with internal structures.
