AbstractThe trigeminocardiac reflex (TCR) is triggered by stimulation of a branch of the trigeminal nerve and results in vagally mediated bradycardia, hypotension, apnea, and gastrointestinal hypermotility. In the operating theatre, patients susceptible to TCR are typically under general anesthesia; thus, cardiac abnormalities are the most common manifestation. Our case highlights the less common intraoperative manifestations of gastric hypermotility and apnea in a patient undergoing awake craniotomy for tumor resection. Prompt recognition, removal of stimuli, and airway management prevented catastrophic complications while facilitating completion of the procedure.Copyright © 2021 International Anesthesia Research Society.
