Conducted energy device
- Conducted Energy Device, Conducted Energy Weapon, Electronic Control Device, Electrical Control Device, and Electronic Control Weapon all refer to same thing
- Commonly referred to as Tasers by lay public
- Purpose of a Conducted Energy Device (CED) is to provide law enforcement officers with broader choices on use of force spectrum
- Used to control combative individuals
- 99.75% of time no significant injury as result of using device per Department of Justice (DOJ) study 
Mechanism of Action
- Either through direct contact or with fired probes, which penetrate up to 1/2 inch into body a current is delivered which causes neuromuscular interference resulting in temporary paralysis for seconds which often results in uncontrolled fall.
- Electrical current captures skeletal muscle and tends to stay on outside of muscle
- Immediate relief occurs after application of energy ceases.
- Consider underlying reason why CEDs was used i.e. medical crisis, serious physiological distress, drug/alcohol intoxication, altered mental status, combative individual
- Pain secondary to induced forceful muscle contracture
- Puncture wound and often minor burn from barbs
- +/- signs/symptoms of trauma from uncontrolled fall
- No clinically relevant changes in ventilation, acid-base status, electrolyte concentrations, troponin I level or EKG noted 
- Routine history and physical examination
- Consider history of cardiac disease
- Consider history of pacemaker/defibrillator
- Consider drug or alcohol intoxication, psychiatric disturbance, altered mental status
- Look for direct injury from barb and indirect injury from fall
- No need for routine performance of labs, EKGs, or prolonged observation after CED exposure in otherwise awake and alert patient
- More extensive testing and evaluation may be appropriate in individual cases based on history and physical examination i.e. EKG if chest pain, palpitations, or cardiac history
- Barb removal then wound care for small puncture wound and minor burn at barb site
- Most healthy individuals may be discharged (often to the custody of law enforcement) after barb removal
- Appropriate medical intervention/consultation if barb in vulnerable area such as mouth, eyes, neck, groin
