General anesthesia includes sedation, analgesia and muscle relaxation. During general anesthesia, patients are generally unconscious, that is, they are completely unaware of the operation process. Patients using general anesthesia for comprehensive rhinoplasty, rhytidectomy, facial laser lipolysis, mandibular angle resection, autologous fat breast enhancement, prosthesis breast enhancement, liposuction surgery and breast reduction surgery have better effects.
