Sudden Pulseless Ventricular Tacchycardia during the Emergence of a Child after the General Anesthesia, and Suspected Viral Myocarditis

Abstract

A 10-year-old female child was underwent the tonsillectomy and adenoidectomy. She was relieved from the upper respiratory tract infection about 1 week before the operation. Her heart rate was recorded 100 to 110 per minute at the preanesthetic period, and then increased to about 140 per minute during the operation. We speculated that tacchycardia resulted from the inhalation anesthesia of sevoflurane as other common cases, so we didn't consider it as a serious problem. But the taccycardia was not relieved after the termination of anesthesia, and after the extubation, it was severely and rapidly aggravated to the ventricular tacchycardia with the circulatory collapse during the emergence period. After the rapid defibrillation and the chest compression, her resuscitation was successfully finished. We suspected her event was derived from the childhood cardiomyopathy, especially the viral myocarditis. So we reviewed viral myocarditis and focused a new aspect of childhood cardiac disease and screening.
