Skin vascular constriction in a reticular pattern is thought to be characteristic of a lightning injury. Electrical shock injury is an injury caused by the passage of electric current through the body. They are usually caused by inadvertent electrocution or lightning strikes. Lighter cases after electrocution only show painful muscle contractions, panic, pallor, headache, dizziness, and palpitations. Serious cases can lead to loss of consciousness, shock, cardiac and respiratory arrest, and often severe ventricular arrhythmias, pulmonary edema, gastrointestinal bleeding, coagulation dysfunction, and acute renal insufficiency after an electric shock. Special clinical attention should be paid to the possibility that the injured person has multiple injuries, including mandatory muscle damage, visceral organ damage, and internal and external burns. Survivors may have cardiac and neurological sequelae. Severe burns from high-voltage electrocution are common at the site of current entry and exit. The most striking feature of electrocution trauma is the small trauma to the skin and the extensive deep tissue damage under the skin. History of lightning injury, when a person is struck by lightning, heartbeat and respiration often stop immediately, accompanied by myocardial damage. Skin vasoconstriction in a reticular pattern is thought to be characteristic of lightning injury. This is followed by myoglobulinuria. Other clinical manifestations are similar to those of high-voltage electrical injury. General investigations include ECG examination, blood pressure monitoring, respiratory examination, etc. The simpler the test, the better, so that the patient can be better rescued in a race to the bottom. Electrocardiogram may show various arrhythmias, acute myocardial injury, and non-specific ST-T changes. x-ray may show fractures. Prevention of skin vasoconstriction in a reticulated pattern should be popularized with general education on electricity and compliance with safe electricity use. Any electrical appliance that may come into contact with or be touched by the human body or threaten life, should be well grounded and have protective circuit breakers within the circuit. Ground fault circuit breakers can trip and cut the circuit when the earth leaks at as low as 5mA and are readily available. Preventing lightning strikes includes applying common sense and proper protective devices, knowing the weather forecast and finding a suitable place to take shelter from lightning storms.
