Electrical Burns and Injuries
Electrical burns and injuries happen when electric currents pass through the body. The currents can damage the skin, tissues, and major organs. The damage can range from minor to severe. Sometimes it is fatal.
Electrical burns and injuries are caused by contact with electrical currents. The currents may come from appliances, exposed wiring, or lightning strikes.
Things that raise the risk are:
- Having a job with exposure to electric currents
- Working outdoors
- Being outside during thunderstorms
- Working with electric systems or appliances without proper training
Symptoms depend on the amount of electricity and length of exposure.
Symptoms may be:
- Severe muscle spasms
- Numbness or tingling
- Weakness or lightheadedness
- Burns on the skin
- Heart pounding or fluttering from heart arrhythmias
Electric shock can also cause the lungs and heart to stop working.
Diagnosis is based on events and symptoms. A physical exam will be done.
The doctor will look at the skin. Burns will be diagnosed based on how severe they are:
