General anesthesia surgery requires tracheal intubation, because the patient can not breathe on their own after anesthesia, can not meet the body’s required oxygen supply, the need for tracheal intubation, inserted into the trachea through the mouth or nose, connected to the respiratory machine, ventilator-assisted instead of independent breathing. General anesthesia intubation is mainly applicable to more major surgery, like intracranial surgery, open thoracic surgery, abdominal surgery, can effectively keep the airway open, to ensure the safety of the patient’s surgery. Before surgery for these diseases, the doctor will conduct an assessment to inform the patient’s condition whether general anesthesia intubation is required. Some complications may occur after intubation, and patients as well as their families will be informed of the risks of general anesthesia and intubation before surgery, and there may be pharyngeal discomfort and other symptoms after extubation at a later stage.
