The purpose of this study was to determine the frequency of unexpected events during intermittent vagal nerve stimulation in 24 patients stimulated for a total of 61 patient years. The charts of 24 children undergoing periodic stimulation of the left vagal nerve on research protocols were reviewed to determine the nature and frequency of adverse events and the total length of time they were stimulated. Fifteen adverse events were discovered in 12 patients. Thirteen were likely related to the device, and four other events might have been related. Two of these resulted in voluntary termination of vagal nerve stimulation, and the rest were treatable. Vagal nerve stimulation was tolerated in this series of patients. As opposed to the more standard drug therapies, adverse events during vagal nerve stimulation do not necessitate termination of therapy, but these events frequently lead to unforeseen surgery under general anesthesia.
