Anesthesia is generally divided into two types, local anesthesia and general anesthesia. Local anesthesia is the use of local anesthesia drugs, injection into muscle, nerve tissue around, so that the nerve tissue impulse transmission is blocked, so as to produce the effect of pain disappear, so that the patient can not feel the pain of surgery. The impact of local anesthesia on human body is relatively small, but there are still risks, such as allergic reaction, hypersensitivity reaction, toxic reaction, tissue or nerve damage, some patients have severe anaphylactic shock or toxic reaction, and even death. Is the use of general anesthesia general anesthesia drugs, injection into a vein or muscle, to the brain, make a person to sleep, painless state, its mechanism is similar to drunk, this state, the patient can completely avoid the psychological impact of fear, completely avoid the stimulation of pain, and most of the operation of the bad stimulation, let patients can accept the larger, complex surgery. One of the most common questions patients ask after general anesthesia is: Has the operation been done? Well, that's one of the advantages of general anesthesia. As for the influence of general anesthesia, Chinese people have a prejudice that general anesthesia will affect the brain, resulting in stupid, memory loss, etc. However, general anesthesia is very popular in foreign countries, and most patients are operated or even filled with teeth under general anesthesia. Foreign studies show that general anesthesia itself does not affect the brain. General anesthesia affects the human body as well as local anesthesia, which is a risk issue. The risk difference between them: the risk of general anesthesia is greater than that of local anesthesia, mainly manifested in the inhibition of circulatory system and respiratory system, may lead to serious complications and even death. But the incidence of serious complications from general anesthesia is low and relatively safe, akin to a plane crash. Clinically, if a patient suffers from a serious disease and cannot tolerate general anesthesia, local anesthesia should be selected as far as possible, or if the treatment time is relatively short and the operation is relatively small, and the patient can endure fear and pain and insist on finishing the treatment, local anesthesia can also be selected, otherwise it is best to accept general anesthesia.
