It is possible to vomit things out by drinking a lot of water, stimulating the back wall of the pharynx, and medication such as copper sulfate.
1. Drinking a lot of water: Let the patient drink a lot of water first, and then press the upper abdomen, which can make the things in the stomach spit out.
2. Stimulate the posterior wall of the pharynx: you can use a chopstick, spoon handle, fingertips, open your mouth and gently stimulate the posterior wall of the pharynx, which will reflexively cause vomiting movements to help spit things out, and be careful not to stimulate too violently and too often.
3. Drug treatment: central emetic drugs, such as apomorphine hydrochloride, copper sulfate, etc., can be used in emergency poisoning, so that the patient quickly vomit out the poison in the stomach. Drugs should be used under the guidance of a doctor.
The above methods are applicable to conscious patients, and those who are not conscious are recommended to go to the hospital to wash out the toxins in the stomach through gastric lavage.
