[Fiberoptic intubation via laryngeal mask airway under general anesthesia in the patients with halo vest].

Since 1991, we gave anesthesia to 155 patients with halo vest. All of 128 whose airways could be kept patent by laryngeal mask airway (LMA) were successfully intubated fiberoptically via LMA using the tube exchange catheter under general anesthesia. Four patients developed airway obstruction during the induction of anesthesia, two of whom were awakened and subsequently intubated by awake fiberoptic intubation.
