What's the difference between semi-anesthesia and general anesthesia?

Surgery is generally divided into general anesthesia and local anesthesia (semi-anesthesia), and the type of anesthesia will be judged according to the risk of surgery. Anyone who knows surgery knows that major surgery always involves anesthesia. We often say that semi-anesthesia is actually local anesthesia, which is called differently in different places, and then refers to anesthesia in a certain part of the body. General anesthesia, as its name implies, is to put anesthetic directly into meridians to put people's brain into a dormant state and avoid any action that will affect the operation during the operation.

First, dangerous surgery, or surgery involving easy access to arteries, will directly use general anesthesia.

General anesthesia, which we call general anesthesia, is to inject anesthetic into the body through veins and then flow to the brain, so that the brain is in a deep sleep state. It does not completely anesthetize the body, but anesthetize the brain; In large-scale operations, people who are worried about the danger caused by the slight movement of the patient during the operation will adopt general anesthesia to keep the patient in a state of sleep, so as to achieve a perfect operation. Of course, anyone who knows about brain anesthesia knows that general anesthesia has a great influence on patients, and even they may have amnesia for a while. Due to anesthesia, Bian Xiao could not remember some memories for some time.

Secondly, for less dangerous and controllable surgery, only local anesthesia is generally selected to reduce the harm to human body.

Considering the great influence of general anesthesia on people, local anesthesia will be carried out according to the danger of operation in the current operation; Local anesthesia, which some people will call semi-anesthesia, does not mean that half of the body is anesthetized, but a comparison with general anesthesia. Caesarean section and local surgery will use local anesthesia. As long as the operation is not dangerous, general anesthesia will not be chosen. After all, general anesthesia does have a lot of effects on the human body, and some people may even be in danger because of general anesthesia.

General anesthesia means that the anesthetic acts on the brain to make the patient fall asleep. Semi-anesthesia is local anesthesia, and a certain part of the body is anesthetized.
