Toaster Electrocution Electrical Injury

Primary determination of injury extent = amount of CURRENT flowing through body.

VARIABLES: voltage, amperage, resistance, type of current (AC/DC), duration, pathway.

INJURY TYPES

1. Low-Voltage <1000V

2. High-Voltage >1000V - typically seen in industrial settings or power line injuries.Associated with electrical burns

3. Lightning Strike

4. Electric Arc- associated with high voltage source

5. Blast force may result in trauma.

DC- direct current (lightening)

AC- alternating (household)

ORGAN SYSTEMS:

1. CARDIAC: asytole or Vfib prehospital. At presentation, most common is Afib.

2. VASC: necrosis, coagulation, compartment syndrome

3. CNS- stroke, seizure, syncope

4. ORTHO- fracture/dislocate

5. OCULAR- cataracts (later on)

6. GI

7. DERM - various burns

IMMEDIATELY: cardiac arrest (arrthymia), seizure, respiratory arrest.

KEYS: reverse triage -> mutliple patients, start with those in cardiac/respiratory arrest. . EKG, labs, cardiac monitoring, check for rhabdomyolysis .

DISCHARGE->asymptomatic patients with normal ECG on presentation after a low-voltage electrical injury.

ADMIT-> all patients with high-voltage injuries (even if asymptomatic). Patients with low-voltage injury if symptomatic (e.g. LOC, severe burns, ECG changes, ↑ CK). Abnormal ECG or observed dysrhythmia..Cardiac biomarkers positive. Persistent chest pain, paresthesias, or hypoxia .Cardiac arrest..History of significant cardiac disease or CAD risk factor.

WARNING: do NOT recreate video.
