Succinylcholine-induced ventricular arrhythmia during halothane anesthesia.
A case of ventricular tachycardia in a healthy child subsequent to onset of a succinylcholine infusion is described. A 9-year-old male patient was scheduled for an adenoidectomy and bilateral tonsillectomies. There was no history of cardiac arrhythmia. Anesthesia was induced by mask with nitrous oxide and halothane. Immediately after the infusion of 20 mg of succinylcholine, the heart rate was 150 beats/min and then the electrocardiograph (ECG) revealed a short run of ventricular tachycardia. The patient was given 1 mg of propranolol, and enflurane and 100% oxygen were administered. Soon after the propranolol was given, normal sinus rhythm returned. Ventricular tachycardia may occur after a single dose of succinylcholine in a healthy anesthetized child without predisposing disease.
