Thoracoscopic surgery needs to be performed under general anesthesia because the patient needs to be fully anesthetized to make an incision in the chest wall under anesthesia and to implant thoracoscopic instruments to complete the procedure in question, as it involves deep manipulation including tracheal traction and exposure, including exposure of lung tissue. In the non-anesthetized state, the patient may have tension or anxiety, as well as intolerance to pain or poor cooperation, when the procedure cannot be performed. Therefore, for this type of surgery, the patient is required to undergo general anesthesia, because this part of the procedure requires the patient to be pain-free, unconscious, no muscle tension, contraction and no coughing or spontaneous breathing can be completed, and only in this condition the patient does not need to cooperate with special cooperation, this time the patient is not conscious and does not need to actively cooperate with the doctor. Tissue pulling or exposure will not harass the patient, this time to carry out the operation will have a higher safety coefficient. General anesthesia including tracheal intubation for inhalation anesthesia, but also includes intravenous anesthesia for analgesia or sedation, muscle relaxation and other drugs, a combination of the two anesthesia for general anesthesia in order to complete this type of surgery.
