General anesthesia is general anesthesia, which means that after inhaling drugs through respiratory tract or injecting drugs through vein, the central nervous system is suppressed, the patient's consciousness disappears, the whole body pain disappears, and the muscles are relaxed to a certain extent.

Intubation means endotracheal intubation. After anesthesia, the patient can't breathe spontaneously. It is an anesthesia method that inserting endotracheal tube into trachea, keeping the patient's respiratory tract normal, and connecting with ventilator, and using ventilator to assist rather than spontaneous breathing.

Extended data

General anesthesia methods commonly used in clinic include inhalation anesthesia, intravenous anesthesia and compound anesthesia. The implementation of general anesthesia can be divided into pretreatment, induction, maintenance and recovery.

Inhalation anesthesia refers to a general anesthesia method in which volatile anesthetics or anesthetic gases are absorbed into the blood by the anesthesia machine through the respiratory system to inhibit the central nervous system. Inhalation anesthesia is the earliest anesthesia method in the history of anesthesia, and ether is commonly known as inhalation anesthesia. However, due to its unstable, flammable and explosive characteristics, modern operating rooms need electrotome and other equipment.

Therefore, ether may cause explosion, and it has been abandoned in clinic now. Inhalation anesthesia has developed into the main method of general anesthesia. Inhalation anesthesia has little metabolic decomposition in the body, and most of it is discharged from the lungs in its original form, so inhalation anesthesia has high controllability, safety and effectiveness.
