If the patient accidentally drank a mouthful of diesel fuel, the general body will not appear uncomfortable symptoms, and do not need to do special treatment. Patients drink a mouthful of diesel fuel about 30-35 ml, generally less harmful to the human body, the patient generally will not appear uncomfortable, because the human body’s oral cavity and gastrointestinal mucosa have a role in defense, and the human body can not be absorbed. Diesel fuel will be discharged directly from the body after passing through the gastrointestinal tract, so it basically has no effect on the human body. If patients drink a larger mouthful, greater than 100 ml, you can take a lot of milk and egg whites to neutralize diesel fuel, and go to the hospital as soon as possible, under the guidance of the doctor for gastric lavage and diarrhea and other treatments to promote the discharge of diesel fuel. Regardless of how much is drunk, if there are symptoms of discomfort, you should go to the hospital as soon as possible.
