Electric burn cause of disease: electric current can make the ion balance outside airframe cell membrane produces change, and can produce the reaction such as electric current, electroosmosis.

Electric burn pathogenesis: sufficient concentration of ion flow can stimulate excited nerve, muscle tissue, cause muscle tissue contraction.Skin tissue can produce heat when energized, causing burns and carbonization.When the electric current passes through the heart, brain medulla, spinal cord and other important tissues, organs, it will produce serious consequences, even cause death.

Electric burns symptoms: local electric shock mainly manifested as electric burns, with the current investment mouth injury is the most serious.Local skin tan dry burn, carbonization, and damage can be deep musculoskeletal.If an electrical injury is accompanied by a high-temperature arc flash or spark, extensive thermal burns may occur on the surrounding skin.Secondary infections, such as local blood vessel damage, can lead to bleeding.Depending on the severity of electrical injury, there may be different degrees of systemic reactions.Light only feel dizziness, palpitation, pale complexion, weak limbs, systemic weakness and other symptoms;Severe cases can include convulsions, shock and even death.Based on the history, the clinical manifestations can make a diagnosis.

By electric injury how to do?

1. Patients in bed rest, including those with small mouth and small skin burn area, should carefully observe the changes of the condition.Exposure therapy is commonly used to keep the injured limb clean and dry and to disinfect the skin 2-3 times a day.

2. The first operation is feasible 3 ~ 5 days after the injury.The necrotic tissue or eschar was resected and the deep tissue was explored.If there is no obvious infection, the inactivated tissue is completely removed (no blood, no contraction of the muscle by electric stimulation, etc.), and then bandaged with liquid gauze.The necrotic tissue was removed at intervals of 2-3 days until the wound could be sutured or skin grafted.

3, the wound has been infected to fully drainage, wet compress, day by day to cut off the necrotic tissue and eschar, until the wound growth granulation and healing or skin graft repair.Extensive deep infection is very easy to lead to toxemia, sepsis, acute renal failure, in addition to the application of large doses of antibiotics, must be in time to make more open drainage, and even have to do not line amputation.There is a risk of bleeding from exposed wounds. Compression hemostasis and medication hemostasis can only have a transient effect.A tourniquet and operating bag should be prepared at the bedside.
