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. Symptoms will be treated.

Tests that may be done include:

• Blood and urine tests
• Bronchoscopy -- camera placed down the throat to look for burns in the airways and lungs
• Chest x-ray
• Electrocardiogram (ECG)
• Endoscopy -- camera placed down the throat to check for burns in the esophagus and stomach

Treatment may include:

• Breathing support, including tube through the mouth into the lungs and connected to a breathing machine (ventilator)
• Fluids through a vein (by IV)
• Medicine to treat symptoms
• Surgery to remove burned skin (debridement)
• Washing of the skin (irrigation), every few hours or for several days

Outlook (Prognosis)

How well someone does depends on how much steam iron cleaner they swallowed and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery. Steam iron cleaner can cause extensive damage to the:

• Esophagus
• Eyes
• Lungs
• Mouth
• Nose
• Stomach
• Throat

Delayed injury may occur, including a hole forming in the throat, esophagus, or stomach. This can lead to severe bleeding and infection. Surgical procedures may be needed to correct these complications.

If the cleaner gets in the eye, ulcers may develop in the cornea, the clear part of the eye. This can cause blindness.
