a state of shock similar to others (for example, spinal shock, q.v.) in its ability to lead to inadequate perfusion. It is caused by interruption of vasomotor tone by injury to the autonomic nervous system. Often differentiated in clinical presentation, where the classic signs of tachycardia and cutaneous diaphoresis (that is, cool clammy skin) are absent.
