Alternate Names : Gastric Lavage, Gastric Suctioning
Stomach pumping is done to
remove toxic substances that a person has accidentally or purposely swallowed.
Who is a candidate for the procedure?
Anyone who has
swallowed a poisonous substance or an overdose of drugs is a candidate
for stomach pumping. A person's stomach may be pumped if he or she refuses to
take medication to cause vomiting.
Sometimes a person should not vomit, if certain types of poisons have been
swallowed. In these cases, the person's stomach may be pumped. Stomach pumping can also be used to collect a sample of the material that was ingested.
How is the procedure performed?
Stomach pumping should be
done as soon as possible after the person has swallowed the substance. This
decreases the time the body is exposed to the poison. It also prevents drugs
from being absorbed, if the person has taken an overdose.
If the person is unconscious or uncooperative, an endotracheal tube is inserted before the stomach is pumped.
This is a tube that protects the airway, and prevents the person from breathing the stomach fluids into the lungs.
The person is placed on the left side, with the head lowered. A lubricated
stomach tube is gently inserted
through the mouth, into the esophagus, and down to the stomach. The contents
of the stomach are then suctioned out through the tube. The stomach can then
be washed out with lukewarm water or salt water. This is done repeatedly until the fluids that come out of the stomach are clear.
Depending on what was swallowed, the person may be given activated charcoal
after the stomach is pumped. The charcoal absorbs any drugs or poisons that
may still be in the stomach. Activated charcoal can be given with a cathartic, which is a medication that speeds the emptying of the intestines.
