Vagal nerve stimulation therapy

Abstract

Devices, systems and methods are provided for treating post-operative symptoms following major surgery and/or for treating patients in critical or intensive care. A method includes positioning a contact surface of a device in contact with an outer skin surface of patient and applying an electrical impulse transcutaneously from the device through the outer skin surface of the patient to a vagus nerve in the patient for about 60 seconds to about 5 minutes. The electrical impulse is sufficient to modify the vagus nerve such that the symptoms are reduced. A stimulation protocol is provided that includes two or more doses administered per day for a period of time sufficient to relieve the symptoms. The doses may be administered before and after the patient's surgery, or while the patient is being treating in intensive care.
