Sudden cardiac death in excited delirium, and how to prevent it

Abstract

The purpose of this study was to review data on restraint related deaths in persons in a state of excited delirium (ExDS) and to propose guidelines for treatment. We analysed three unexpected deaths in persons in a state of ExDS shortly after police restraint. Death which occurs during a police intervention, using physical restraints, may be related to placing the individual in a prone position, the use of neck holds, expert grips, and handcuffs or pepper spray. ExDS results in an altered mental state with agitation, aggression, paranoia, and panic attacks, and is a life-threatening condition. Therefore, before police intervention is initiated, a medical emergency team should be present. In patients with ExDS, physical restraints used by the police should be brief, effective, and include rapid tranquilization (sedation) using benzodiazepines, and antipsychotics.
