According to the emergency doctor, the injured person was seriously injured, and the skin of the whole upper body, head, chest and lower limbs fell off, causing pain and limited movement, among which the left hand was seriously injured. It is reported that due to the large burn area, the medical staff has treated it symptomatically when entering the hospital. There is no life-threatening at present, but it is mainly to prevent infection. Burn scab

Tian Yifei, a burn doctor in Guangdong Armed Police Corps Hospital, pointed out: Generally speaking, the larger the burn area, the deeper the burn depth, the more difficult the treatment and the worse the prognosis. Therefore, the first-aid measure is to "put out the fire", that is, to remove the source of injury and try to "burn less and burn less". The patient's head is iron black.

Introduce several commonly used first aid methods:

First, take off clothes soaked in fire or boiling liquid as soon as possible, especially chemical fiber clothes. In order to prevent the hydrothermal solution on the burning clothes or clothes from continuing to act, the wound will be enlarged and deepened.

The second is to put out the fire with water, or jump into a nearby pool or river ditch.

Third, after lying down quickly, slowly roll on the ground and crush the flame. Don't stand, run or call when the wounded clothes are on fire, so as not to aggravate head and face burns or inhalation injuries.

Fourth, leave the closed and poorly ventilated site quickly to avoid inhalation injury and suffocation.

Fifth, quickly cover the fire with non-flammable items around you, such as blankets, coats and quilts. In order to isolate it from the air and put out the fire. Six, timely cold therapy cold therapy can prevent heat from deepening the wound after thermal burn, and can relieve pain, reduce exudation and edema. Therefore, if conditions permit, cold therapy should be carried out as soon as possible, and the earlier the effect, the better.

Seventh, besides the nature and concentration of acid and alkali, the severity of acid and alkali burns is mostly related to contact time. Therefore, no matter what kind of acid-base burn, it should be washed immediately with plenty of water for at least 30 minutes. On the one hand, it can dilute and remove the residual acid and alkali, on the other hand, as a way of cold therapy, it can relieve pain. Note that the initial water consumption should be large enough to quickly wash the acid and alkali left in the wound. When the head and face are burned by acid and alkali, we should first pay attention to whether the eyes, especially the cornea, are burned and give priority to washing.

Eight is the first aid for electric burns, you should immediately cut off the power supply, open the switch or use non-conductive items (wooden sticks or bamboo utensils, etc.). Unplug the power and put out the burning clothes. Before cutting off the power supply, emergency personnel should remember not to touch the wounded to avoid electric shock. After the fire fighting, if the wounded person's breathing and heartbeat stop, he should immediately carry out external heart massage and mouth-to-mouth artificial respiration at the scene. After the heartbeat and breathing recover, he should be transferred to the nearest hospital for further treatment in time; Or while continuing cardiopulmonary resuscitation, quickly transfer the wounded to the nearest medical unit for treatment. ?
