[Assessment of Motor and Language Function during Awake Surgery].

Awake surgery enables the evaluation of neurological functions that are difficult to assess with a conventional electrophysiological examination and is useful in the evaluation of language function. Awake surgery is a team effort involving anesthesiologists and rehabilitation physicians who evaluate motor and language functions, and information sharing during the perioperative period is important. Some points regarding surgical preparation and anesthesia methods are unique and must be well understood. For example, supraglottic airway devices must be used to secure the airway, and ventilation must be checked for availability when positioning the patient. Preoperative neurological evaluation is important in determining the method of intraoperative neurological evaluation, including choosing the simplest possible method of evaluation and sharing the information with the patient prior to surgery. Motor function assessment evaluates small movements that do not affect the surgery. Visual naming and auditory comprehension are useful in the evaluation of language function.
