Food poisoning can be an acute toxic illness caused by ingested food contaminated with bacteria or bacterial toxins, or by food containing toxins. Treatment varies depending on the cause of the illness. If the food is contaminated by bacteria or bacterial toxins, general treatment, symptomatic treatment and antibacterial treatment are needed. 1. General treatment: bed rest, early diet should be easy to digest fluid or semi-fluid diet, after the condition improves, normal diet can be resumed. 2. Symptomatic treatment: for those with obvious vomiting and abdominal pain, scopolamine can be injected. Those who can eat should be given oral rehydration solution. For those who can’t eat due to severe vomiting or have frequent diarrhea, sugar saline should be given. 3. Antibacterial treatment: generally, antibacterial drugs can be dispensed with. With high fever, etc. need to use antibacterial drugs. If Salmonella can use quinolone antibiotics. If the food contains toxins such as sprouted potatoes, sour soup poisoning, etc. should be carried out first aid measures are emetic, gastric lavage, diarrhea and hemodialysis. 1. Emetic: In the early stages of food poisoning, it is advisable to induce vomiting as soon as possible, which can be done by stimulating the posterior wall of the pharynx with disposable cotton swabs. 2. Gastric lavage: If the patient is taken to the hospital at an early stage of poisoning, gastric lavage should be performed as soon as possible. Early and effective gastric lavage is crucial to the prognosis of food poisoning. 3. Diarrhea: If the food has been poisoned for several hours and the toxic substances have entered the intestines, laxatives can be swallowed to expel the poison. 4. Hemodialysis: When the above first aid measures are ineffective, hemodialysis can be considered, i.e., the poisons will be eliminated from the body by means of hemodialysis. Early first aid for food poisoning is of great significance. After poisoning, one should seek medical treatment immediately and treat accordingly under the guidance of professional doctors.
