In case of aminophylline tablet poisoning, the patient should be treated with gastric lavage quickly. If the patient is conscious during routine gastric lavage, it can be performed by hyperventilation, and if the patient is unconscious, it can be performed by intubation and mechanical gastric lavage with a gastric lavage machine, and the amount of gastric lavage solution should be above 10,000 ml as much as possible. In addition, after gastric lavage, enema can be performed, and catheterization treatment can also be given. Diuretics, such as hydrochlorothiazide or furosemide, can also be used to accelerate the metabolism of aminophylline tablets in the body. However, if the patient has obvious convulsions, heart rate, blood pressure, pulse rate and oxygen saturation should be monitored, and if necessary, sedative drugs can be applied to control the convulsions, while fluids can be administered, and continuous blood purification can also be applied to eliminate the excessive aminophylline from the body.
