Electrical treatment of coma via the median nerve.

ABSTRACT

The median nerve is a portal to interact with the injured comatose brain. Peripheral nerve electrical stimulation has a central nervous system effect. Two to three weeks of right median nerve stimulation (RMNS) can hasten awakening from deep coma by increasing the dopamine levels. Three cases of electrically treated GCS-4 teenagers with acute diffuse brain injuries from motor vehicle crashes are presented by video. Pilot studies of RMNS for acute post-traumatic coma states have been done over the last ten years at East Carolina University and the University of Virginia. The neurophysiological effects of RMNS have been well documented at several neurosurgical centers in Japan using neuroimaging and spinal fluid assays. RMNS is a safe, inexpensive, non-invasive therapy for neuro-resuscitation of coma patients. When employed early in the coma, the time in the ICU may be shortened and the quality of the final outcome may be enhanced.
