Preservation of language function by mapping the arcuate fasciculus using intraoperative corticocortical evoked potential under general anesthesia in glioma surgery.
Intraoperative language mapping under general anesthesia is imperative for brain tumor surgery because awake surgery is not always feasible. Monitoring corticocortical evoked potential (CCEP) is known to be a useful method for tracking neuronal connectivity and localizing functional areas. The authors evaluated the clinical benefit of intraoperative CCEP monitoring for language function preservation in patients undergoing glioma surgery. ⋯ Intraoperative CCEP monitoring of the arcuate fasciculus is an acceptable technology for the preservation of language function under general anesthesia in glioma surgery in patients in whom awake surgery is not feasible.

Case Reports
Knotting together of gastric and tracheal tubes inserted under general anesthesia: A CARE-compliant case report.
Gastric tube implantation is a routine part of preoperative preparation. Indwelling gastric tubes in patients under general anesthesia maintain gastrointestinal decompression and prevent gastrointestinal expansion. ⋯ We recommend that the gastric tube be intubated first before insertion of the endotracheal tube, and visualization tools should be used in time if the insertion of the gastric tube is unsuccessful.

Observational Study
Transition in eye gaze as a predictor of emergence from general anesthesia in children and adults: a prospective observational study.
It is useful to monitor eye movements during general anesthesia, but few studies have examined neurological finding of the eyes during emergence from general anesthesia maintained with short-acting opioids and volatile anesthetics. ⋯ In children, eye-gaze transition was observed significantly earlier than other physical-behavioral responses during emergence from general anesthesia and seemed to reflect emergence from anesthesia. In contrast, observation of eye gaze was not a useful indicator of emergence from anesthesia in adults.

Based on the upper airway anatomy and joint function parameters examined by ultrasound, a multiparameter ultrasound model for difficult airway assessment (ultrasound model) was established, and we evaluated its ability to predict difficult airways. ⋯ The ultrasound model has good predictive performance for difficult airways.
