  • Title: [Heart arrest during fibro-bronchoscopic intubation in a patient with parapharyngeal space neoplasia].

    Abstract:
    A 37-year-old woman a diagnosis of squamous carcinoma of the tongue and a history of partial/hemiglossectomy with cervical lymphadenectomy and postoperative radiotherapy was scheduled for biopsy under general anesthesia given the suspicion of local recurrence. She underwent routine preparation for intubation with a fiberoptic bronchoscope with topical anesthesia of mucosal tissue without sedation. Syncope and asystole presented suddenly during intubation and external cardiopulmonary resuscitation and difficult ventilation through a face mask were necessary. She was finally intubated using a retrograde technique and recovered heartbeat after 20 minutes. No neurological sequelae were observed over the next few days. The etiologic diagnosis of this rare complication was later based on the appearance of the characteristic clinical profile of glossopharyngeal neuralgia-asystole syndrome in combination with parapharyngeal space lesion syncope syndrome; magnetic resonance findings of extensive neoplastic invasion of the space confirmed the diagnosis. Endotracheal intubation with a fiberoptic bronchoscope plays an important role in the management of the anticipated difficult airway. It is safe in the awake patient and facilitates the identification of structures, particularly when there are anatomical alterations due to neoplastic invasion, surgery, or radiotherapy. In the patient we describe, however, stimulation caused asystole.
