Transient ventricular bigeminy during emergence from general anesthesia in a pediatric patient with catecholaminergic polymorphic ventricular tachycardia.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare genetic disease that is characterized by ventricular arrhythmias and sudden death, induced by exogenous and endogenous catecholamine. We performed general anesthesia for dental treatment of multiple teeth in a 7-year-old boy with CPVT. To avoid sympathetic tone, anesthesia was maintained by total intravenous anesthesia, but ventricular bigeminy was induced by stimulation on emergence form general anesthesia.

Combined Use of a Gum Elastic Bougie and Video Laryngoscopy for Intubating a Patient With an Unexpected Laryngeal Papilloma.

This is a case report of a 75-year-old man scheduled for apical resection and cystectomy of odontogenic cysts involving both maxillary central incisors who presented with a previously unknown laryngeal mass that was discovered prior to intubation. Following induction and easy mask ventilation, direct laryngoscopy revealed a large mass on the right side of the glottis that impeded passage of a standard oral endotracheal tube. Successful atraumatic intubation was performed with the combination of a video laryngoscope (King Vision, Ambu Inc, Ballerup, Denmark) and a gum elastic bougie (GEB).
