Esophageal nasopharyngeal catheter in the wake-up anesthesia of the brain function area operations

Abstract

Objective To evaluate the feasibility and safety of the self - developed sound outside the ventilation device - esophageal nasopharynx catheter in brain functional areas surgery applications.Methods 13 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 conscious and can speak with a tube inside the mouth while the physiological monitoring of nerve and brain function area accurately done.Results 13 patients were smoothly intubated,the ventilation conditions were good,the blood gas values were normal.The case wake up with a tube inside the mouth were clear and fluent speech,the brain function areas were accurate determined and the epilepsy focus resection were satisfactory with no neurological deficit.Conclusion The esophageal nasopharyngeal catheter as a new type of soud outside the 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 provided safe,reliable ventilation and airway management for the brain functional areas,particularly the language areas operations anesthesia,and fill the gap of the field.
