1.Stop bleeding measures There is no more common trauma faced in daily life than bleeding, and the correct method of stopping bleeding can win valuable resuscitation time and save the life of the patient. Human blood flows in blood vessels, the blood volume of a normal adult is about 5L, which is as much as two large Coke bottles. If the acute bleeding is more than half of the blood volume, you will have a life-threatening situation, and whether you have some correct knowledge of stopping bleeding can often decide whether the result is life or death. Blood vessels are divided into arteries and veins, arteries have high pressure, fast flow rate, large bleeding, if not effectively suppressed, will soon be life-threatening, the ancients often “draw the sword since b” (cut the neck), cut is the carotid artery, and soon be able to solve the problem (dead), however, most of the daily bleeding is mainly venous bleeding However, most of the daily bleeding is mainly from veins, which have low pressure and slow flow rate, but if they are not effectively controlled, the bleeding can be as much. There are many clinical methods to stop bleeding, such as surgical clamping, use of limb tourniquets, etc., but it is difficult for the general public to quickly grasp without professional medical knowledge. Personally, I think the most practical method to stop bleeding is local compression method, whether arterial or venous bleeding, the first time to take compression measures, specifically a small wound can use a clean tissue, large wounds can use a towel or other local compression, most bleeding can stop, even if more than, at least can also slow down the bleeding speed, to be able to transfer to the hospital to win time. 2, the correct treatment of open wounds in the face of some open wounds, parents are often very worried that it will be infected, the first time to disinfection, to point out that disinfection, treatment is fine, but if incorrect treatment, will not only increase the pain of the injured, but also increase the difficulty of doctors to deal with. Remember the “Bioderma” commercial, a beautiful woman took a sip of soju and sprayed it on a soldier’s wound, followed by a scream. So please keep in mind: disinfectants with alcohol content should never be used directly on open wounds. For example, 75% alcohol, iodine, tincture of iodine, these things are not directly in contact with the wound. General wounds just need to be flushed with tap water or rinsed with hydrogen peroxide, and then come back to the hospital for further treatment. Some people worry whether this will increase the chance of infection, in fact, you can rest assured that a bacterial contact with the wound, to divide and multiply to a sufficient number to cause infection of the wound, at least 6 to 8 hours, so the first few hours of injury can be considered clean, this time is enough for you to deal with the wound, as soon as possible to the hospital will not be a problem. In addition, sometimes in the emergency often see some parents like to use Yunnan Baiyao directly on the wound to stop the bleeding, in fact, this is also wrong, it will increase the chance of wound infection, in addition to increase the difficulty of doctors to deal with, we often have to wash your powder before the wound suture, so what small bump lacerations, what do not need to get, directly take a paper towel to press after going to the hospital is. 3, dealing with burns 1 2 3 degrees, summer sun exposure skin will be red and hot, after a few days off the layer of skin on the okay, this is 1 degree burns, no special treatment, only a little uncomfortable; 2 degree burns shallow 2 degrees and deep 2 degrees, the most commonly encountered and the most important is shallow 2 degrees burns, whether the correct treatment, determine whether the wound can be smoothly healed, whether the consequences of the future will have scars. It is characterized by pain, oozing, localized large blister formation, commonly children are boiling water, boiling soup burns, for this case, the first time with cool water to flush the wound, can reduce heat transfer, reduce the degree of injury. A small range of burns only need to apply some external scald cream (such as: Jing Wanhong, Mabel moist burn cream) can be, a large range of burns must be treated in hospital, blisters generally do not easily tear, the blister surface skin actually play a role in protecting the trauma, do not easily remove. If you get the right treatment, no wound infection, generally about a week wound can be healed, and does not leave a scar (early may be some pigmentation); otherwise the consequences of wound infection will leave an ugly scar. 4, scalp hematoma children sometimes hit the head, a bag, clinically known as scalp hematoma, many parents will go to rub, or that hot egg rub, in fact, are incorrect, the correct way to deal with the injury early can take some ice, after nothing to do, just wait, it will be naturally absorbed, the more you rub, the hematoma may be larger, generally smaller hematoma days to a week or two can be absorbed Parents can rest assured that there will be no adverse consequences, all you need to do is to give enough patience, of course, if the hematoma is getting bigger and bigger, you still need to take the child to the hospital to let the doctor see. 5, nosebleeds dry weather in winter, the nasal mucosa is easy to wear miserable breakage caused by bleeding, sometimes bruises can also lead to bleeding, some native methods such as cold water to wash the nose, wash the face, etc. is actually not very useful, tilting the head actually just let the blood flow into the throat, and can not stop the bleeding, these methods are not very useful, the correct should be some clean soft tissue stuffed into the nose, most bleeding can be stopped in a few moments, this is also the use of the principle of compression This is also the use of the principle of compression (so that compression is the universal method to stop bleeding); of course, there are some deep bleeding or more serious bleeding, may need to go to the hospital by the ENT physician to deal with it. Daily life is full of various dangers and injuries, and having some proper and practical medical knowledge can often solve many problems.
