Summary
Understanding electrical injury mechanisms is key. Despite frequent fatalities, successful resuscitation after cardiopulmonary arrest offers a favorable prognosis for electrical shock survivors.
Area of Science:
- Medical Science
- Physics
- Emergency Medicine
Background:
- Electrical injuries are common, with approximately 3000 survivors admitted to specialized burn units annually.
- Electrocution can be fatal, but outcomes for resuscitated patients are often favorable.
- Predicting the full extent of injury from electrical shock is challenging initially.
Purpose of the Study:
- To review the mechanisms and pathophysiology of electrical injuries.
- To elucidate typical injuries sustained by patients experiencing electrical shock.
- To inform the treatment and prognosis of electrical injury patients.
Main Methods:
- Comprehensive literature search of English-language publications in MEDLINE and reference lists.
- Inclusion of retrospective studies, case reports, and review articles (1966-2005).
- Internet search for information on electrocution and life-threatening electrical injuries.
Main Results:
- Basic physics principles help explain typical electrical shock injuries.
- Electrocution frequently results in death.
- Successful resuscitation after cardiopulmonary arrest in electrical shock victims often leads to a positive prognosis.
Conclusions:
- Familiarity with physics aids in understanding electrical injury.
- Electrical injury patients admitted to intensive care units should be managed as trauma patients.
- Early outcome prediction for electrical shock is difficult due to the delayed manifestation of injury severity.

Electrical Current
Electrical current is defined as the rate at which charge flows. When there is a large current present, such as that used to run a refrigerator, a large amount of charge moves through the wire in a small amount of time. If the current is small, such as that used to operate a handheld calculator, a small amount of charge moves through the circuit over a long period of time. The SI unit for current is the ampere (A), named for the French physicist André-Marie Ampère (1775–1836). An ampere is the...
Household Wiring And Electrical Safety
Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...
Burn Injuries
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Electroconvulsive Therapy
Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early years,...
Spinal Cord Injury ll: Pathophysiology
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
