Definition

Solder is used to connect electric wires or other metal parts together. Solder poisoning occurs when someone swallows solder in large amounts. It can also cause burns to the skin.

Home Treatment

Seek immediate medical help. Do NOT make a person throw up unless told to do so by Poison Control or a health care professional.

If the chemical is on the skin or in the eyes, flush with lots of water for at least 15 minutes.

If the chemical was swallowed, immediately give the person water, unless instructed otherwise by a health care provider. Do NOT give water if the patient is having symptoms (such as vomiting, convulsions, or a decreased level of alertness) that make it hard to swallow.

Before Calling Emergency

Determine the following information:

Patient's age, weight, and condition
Name of the product (ingredients and strengths, if known)
Time it was swallowed
Amount swallowed

Poison Control, or a local emergency number

The National Poison Control Center (1-800-222-1222) can be called 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.

See: Poison control center - emergency number

What to expect at the emergency room

The health care provider will measure and monitor your vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. You may receive:

Activated charcoal
Breathing tube
Bronchoscopy -- camera down the throat to see burns in the airways and lungs
Dialysis
Endoscopy -- camera down the throat to see burns in the esophagus and the stomach
Fluids by IV
Medicine (antidote) to reverse the effect of the poison
Oxygen
Surgical removal of burned skin (skin debridement)
Tube through the mouth into the stomach to wash out the stomach (gastric lavage)
Washing of the skin (irrigation) -- perhaps every few hours for several days

Expectations (prognosis)

How well you do depends on the amount of poison swallowed and how quickly treatment is received. The faster you get medical help, the better the chance for recovery.

Outcomes depend on the type of poison swallowed:

Ethylene glycol is extremely poisonous.
Complete recovery from lead poisoning takes a year or more. It may cause permanent brain damage.
If the amount of zinc or tin swallowed is low, recovery should occur within approximately 6 hours.
Skin color changes due to silver poisoning are permament.
Long-term poisoning with antimony and cadmium may lead to lung cancer.
Recovery from acid poisoning depends on how much tissue has been damaged.
