Absolutely agree with Pete, but I want to add my $.02

1) Shock is due to injury of some sort. Severe emotional distress (e.g. Acute Stress Disorder or Post Traumatic Stress Disorder, or hysteria) is not shock. Nothing like shock, psychologically or physiologically.

2)The only medication ever to give, in the emergency setting, for Psychological "trauma" or "shock" is calm reassurance. No medications are helpful unless the patient absolutely must be sedated emergently to prevent further physical injury. Any medication given to tranquilize a psychologically agitated person may also depress CNS function and may increase risk.
