neck burns
Introduction
Introduction The neck is exposed to the body, which is easy to cause burns. The skin is weak, the tissue elasticity is good, and the appearance is deformed and dysfunctional after burn. The lighter directly affects the appearance and the functional activities of the head and neck. Chest adhesions can affect language, chewing, eating, breathing and other functions. In severe cases, it can affect the development of the mandibular and cervical vertebrae to cause deformation. The skin is often only part of the body burns, the subcutaneous tissue may also be burned, and even if there is no skin burn, there may be internal organ burns.
Cause
Cause
(1) Causes of the disease
Most people think that high temperature is the only cause of burns, however, certain chemicals and currents can also cause burns. The skin is often only part of the body burns, the subcutaneous tissue may also be burned, and even if there is no skin burn, there may be internal organ burns. For example, drinking a very hot liquid or corrosive substances (such as acid) can burn the esophagus and stomach. In a building fire, inhalation of smoke or hot air may cause lung burns.
Burned tissue may be necrotic. When tissue burns, fluid exudation in the blood vessels causes tissue edema. In large-area burns, vascular permeability is abnormal, and a large amount of fluid is lost, which may cause shock. At shock, blood pressure is low and blood flow to the brain and other vital organs is reduced.
Electric burns are caused by high temperatures above 5000 °C when current flows through the body, sometimes referred to as arc burns. At the point where current enters the body, the skin is often completely destroyed and burnt. Because the skin resistance of the contacted charged body is high, a large amount of electrical energy is converted into heat there to burn the surface. Most electrical burns also severely damage the subcutaneous tissue, and the extent and depth of the burn varies. The range of impact may be much larger than the area of burned skin. Severe electrical shock can cause apnea, irregular heartbeat, and cause dangerous heart rate disorders.
Chemical burns can be caused by a variety of irritating and toxic chemicals, including strong acids, strong bases, phenols, toluene (organic solvents), mustard gas, phosphorus, and the like. Chemical burns can cause tissue necrosis and slowly spread a few hours after burns.

1. There is a history of flame burns or high temperature liquid burns.
2. Judging the depth of burn
(1) I degree burn: the skin of the wound is red, swollen, painful, hot, no blister, feels slightly allergic, dry skin, no infection. The local temperature is higher than the wound surface.
(2) Shallow second degree burn: the blisters on the skin of the wound, the wet wounds are revealed after the blisters are removed, the bottom is very red, edema, allergies and severe pain. The local temperature increases.
(3) deep second degree burns: there are blisters but smaller, the blisters are slightly wet and whitish after peeling, sometimes there are multiple red spots or small blood vessel branches, edema is more obvious, there is pain, but the wound feels slower. The local temperature was slightly lower and the plucking test was positive.
(4) III degree burn: the leather surface of the wound is pale or browned, charred, the surface is dry, and there is a leather-like sensation. The large venous branch with embolization can be seen. The pain disappeared and the wound felt dull. The wound is cold. The plucking test was negative.
Diagnosis
Differential diagnosis
There are signs or swellings in the neck: scratches or swelling in the neck are one of the symptoms of traumatic embolization of the carotid artery. The common carotid artery is the main artery of the head and neck, and the upper thyroid cartilage branches into the internal carotid artery and the external carotid artery. The incidence of traumatic embolism is higher in the internal carotid artery. Because the internal carotid artery mainly supplies blood to the brain and the visual device, the embolization has serious consequences. Internal carotid artery embolization can occur in the cervical segment, the rock segment, the cavernous sinus segment or the upper segment of the bed
