Step-by-step explanation:
Gastric lavage, also known as stomach pumping, is a procedure used to remove toxic substances from the stomach after poisoning. It involves inserting a tube through the throat into the stomach and aspirating the contents. Here are the correct statements regarding gastric lavage based on the given options:
- Gastric lavage is only useful within two hours of poisoning. After this time, most of the poison would already be absorbed into the bloodstream.
- In children, 5% glucose solution may be used instead of water for gastric lavage to prevent hypoglycemia.
- If the poison is corrosive, gastric lavage is contraindicated because it can cause further damage to the esophagus and stomach.
- Gastric lavage is typically performed with the patient lying in the left lateral position, not the right lateral position.
- Gastric lavage can be performed on intubated patients, but it is not an absolute requirement.
