- Intravenous (IV) fluids through the vein
- Medicines to treat symptoms
- Tube through the mouth into the stomach to wash out the stomach ( gastric lavage )
- Endoscopy. Camera placed down the throat to see burns in the esophagus and the stomach.
- Medicine (antidote) to reverse the effect of the poison
- Washing of the skin (irrigation), perhaps every few hours for several days
- Skin debridement (surgical removal of burned skin)
- Breathing tube
How well a person does depends on the severity of the poisoning and how quickly medical help was received.
Severe lung damage may occur. Survival past 72 hours usually means the person will have a complete recovery.
Sniffing Freon is extremely dangerous and can lead to long-term brain damage and sudden death.
