What to expect at the emergency room 

Some, or all of the following procedures may be performed:

 
• For swallowed poison       o Placement of a tube down the nose and into the stomach (a nasogastric tube, or an NG tube) to wash out the stomach (gastric lavage)       o Activated charcoal administration       o Endoscopy - the placement of a camera down the throat to see the extent of burns to the esophagus and the stomach       o Give IV fluids       o Admission to the hospital       o Give an antidote       o Treat the symptoms
