Alcohol poisoning is caused by transient large-scale intake of alcohol, which first excites and then inhibits the central nervous system, and then inhibits the medullary vasomotor center and respiratory center. In severe cases, it can cause respiratory failure, respiratory paralysis and death. The disease has an acute onset and progresses rapidly, but if it can be treated in time, it can save the patient's life and reduce the occurrence of complications. Alcohol dependence refers to a series of withdrawal symptoms that can occur in chronic alcoholics once they stop drinking. In fact, alcohol-dependent people are often in a state of poisoning. The incidence of alcohol poisoning in my country is lower than that in Western countries, but its incidence seems to be on the rise in recent years, which should be taken seriously.
