ObjectiveTo evaluate the feasibility and safety of the self-developed sound outside the ventilation device—esophageal nasopharynx catheter in brain functional areas surgery applications.Methods13 patients involved functional areas of brain surgery were chosed.After induction of general anesthesia，the catheters were placed in the esophagus，then connected to anesthesia machines to an external mechanical ventilation.During the operations anesthetic techniques for patients to awaken the consciousness and can speak with a tube inside the mouth while the physiological monitoring of nerve and brain function area accurately done.Results13 patients were smoothly intubated，the ventilation conditions were good，the blood gas values were normal.The case，waked up with a tube inside the mouth，were clear with fluent speech，the brain function areas were accurately determined and the epilepsy focus resection were satisfactory with no neurological deficit.ConclusionThe esophage-al nasopharyngeal catheter as a new type of sound outside ventilation equipment was used in the ventilation for general anesthesia wake-up function，not only the ventilation conditions were good，but also the patients could speak with a tube inside the mouth.It provides safe，reliable ventilation and airway management for the brain functional areas，particularly the language areas operations anesthesia，and fills the gap in this field.10 refs，1 fig.
