Doctors in hospital emergency rooms often see accidental poisonings(中毒). A frightened parent arrives with a child who swallowed a cleaning liquid. Or perhaps the harmful substance is a medicine. Or it might be a chemical product meant to kill insects. These are common causes of accidental poisoning.

In cases like this, look for medical help as soon as possible. Save the container of whatever caused the poisoning. And look on the container for information about anything that stops the effects of the poison. Save anything expelled (被强迫排除) from the mouth of the victim. That way, doctors can examine it.

In the past, some people forced poisoning victims to empty the stomach. They used a liquid syrup of ipecac (催呕剂) to do this. But an organization of children’s doctors no longer advises parents to keep syrup of ipecac. The American Academy of Pediatrics says some poisons can cause additional damage when they come back up the throat.

Millions of people know a way to save a person who is choking on something trapped in the throat. The method is commonly known as the Heimlich Maneuver or abdominal thrusts. The American Red Cross says a rescuer should first hit the person on the back five times between the shoulder bones. These back blows may ease the choking. If the airway is still blocked, the Red Cross suggests pushing hard five times along the victim’s abdomen. The abdomen is the area between the chest and the hip (臀) bones.
