The most frightening thing about superficial injuries is that they bleed out. Especially when this occurs in children, young parents are left with a blank brain and are at a loss for words. Disposal in a panic often brings extremely serious consequences. Blood is a precious fluid in our lives, and if too much blood is lost, it can pose a threat to life. Therefore, it is necessary to learn some correct methods to stop bleeding. How can I stop bleeding quickly? Bleeding from trauma is caused by rupture of blood vessels, cracking of skin surface and blood flowing out of the body, which is generally called external bleeding. If the trauma causes bleeding and the blood in the body decreases to the limit that the body cannot bear, it can cause shock and even endanger the life. One-third of trauma casualties die due to excessive blood loss. According to the nature of bleeding and different arteries and veins, there are different methods to stop bleeding: 1. capillaries: bleeding from capillaries on the surface of the skin is mainly manifested as slow oozing, the bleeding is small and will stop automatically, so there is no danger, and it can be done with “band-aid”. 2, small vein: small vein bleeding faster than capillary bleeding, stop bleeding method is to use clean thick gauze, towels, etc. on the wound, and then pressure bandage, generally will stop bleeding. Common head injury, because the capillaries of the scalp is very rich, often the blood flow, looks terrible, in fact, as long as the pressure bandage on the wound, can soon stop the blood. 3, small arteries: small arteries bleed fast, bleeding, this kind of bleeding if not stopped in time, the body will lose a lot of blood in a short time, shock will occur. Pressure bandage can not stop the blood, only above the wound tie tourniquet, or use a towel, cloth instead of a tourniquet bandage to stop the blood. Three specific methods to stop bleeding An adult can have no obvious symptoms when the blood loss is 500 ml. When the blood loss is 800 ml or more, the injured person can have pale face and lips, cold sweat on the skin, cold and weak hands and feet, shortness of breath, fast and weak pulse, etc. Specific on-site first aid measures are as follows: 1, finger pressure to stop bleeding: If the injured person bleeding from the head, you can use a plastic bag (plastic film) over the fingers, take a clean gauze or paper towels directly press the injured person’s bleeding point, by compressing the blood vessels with the fingers, so that the blood vessels closed and achieve the purpose of temporary hemostasis. 2.Indirect pressure method: Use your thumb to press the superficial temporal artery in front of the ear (1.5 cm in front of the ear screen, with a pulse beating by hand touch), pressing here can improve the bleeding condition of the forehead and the top of the head. 3, pressure bandage to stop bleeding method: use sterilized gauze or clean handkerchiefs, towels, etc. on the wound, and then use triangular towels, handkerchiefs, towels or cloth folded into a band wrapped around the injured limb, pulled tight, knotted, or use sticks, pen sticks, chopsticks and other stick-like objects, rotating at the cloth knot tightened and fixed. Only by applying a certain amount of pressure in this way can the bleeding be stopped. Correct wound dressing method In addition to effectively stopping bleeding, another important aspect of first aid on site is correct wound dressing to achieve the purpose of pressure to stop bleeding, reduce infection, protect the wound and reduce pain. The specific practice is to let the casualty sit or lie down, elevate the injured part, cover the wound with sterile gauze, and the rescuer apply pressure directly on the dressing with his hand for 5-10 minutes; after successful hemostasis, then wrap the dressing with bandages and triangular towels and apply certain pressure to help stop bleeding. After the extremity wound dressing, must check the blood circulation of the fingers or toes, if the injured person feels swelling and numbness of the injured limb, should promptly loosen the bandage and other wrapping items. The use of tobacco, ashes to stop bleeding scientific In many rural areas still maintain some traditional habits, accidental injuries, if the wound is small, bleeding is not much, the people casually grab a handful of ashes, tobacco, charcoal ash and even mud and sand, etc. scattered on the wound. If only from the efficacy of hemostasis, these substances can indeed be effective, because these tiny substances have the function of adsorption, in the bleeding, blood oozing parts can adsorb exudate, and stimulate local small blood vessel contraction, to play a temporary effect of hemostasis. However, items such as incense ash, tobacco, and charcoal ash contain a large number of bacteria, which can easily lead to contamination of the wound surface and cause infection. Moreover, if these items are used to stop bleeding, when the patient comes to the hospital for treatment, the doctor has to clean the wound and remove the foreign body in order to stop bleeding and suturing, and these tiny particles increase the difficulty of removal by the doctor. In short, such a practice is very unfavorable to wound disposal and healing. Health reminders: large, relatively deep bleeding wounds, only ask a doctor to handle and suture, in order to both stop the bleeding and make the wound grow neatly; small arterial bleeding, be sure to ask someone to help stop the bleeding and send to the hospital as soon as possible for further treatment.
