Inhalation of large amounts of alcohol may cause alcohol poisoning. Usually, medical or drinking alcohol is the concentration that the human body can tolerate, and under normal circumstances, inhalation of small doses will generally not cause harm. Patients may experience dizziness for a short period of time after inhaling a small amount of alcohol, but as the body metabolizes the small dose of alcohol can be metabolized and evaporated, generally not causing symptoms of poisoning. If the patient inhales a large dose of alcohol excessively, such as 70g to 80g or so, this may increase the body’s metabolic burden, and cannot metabolize the inhaled alcohol in a short time. Long-term inhalation of large quantities can not be metabolized completely may cause the liver’s detoxification function to decline, which may lead to the phenomenon of alcohol poisoning. Patients should pay attention to protection when using medical alcohol, and should try to avoid excessive alcohol consumption. In case of inhalation of excessive doses of alcohol, the patient should seek medical advice and treatment under the guidance of a doctor.
