Most emergencies are accompanied by bleeding, especially in traumatic hand injuries, to varying degrees. Blood is precious and is the lubricant of life. When faced with bleeding, patients and their families are overwhelmed. They may even aggravate the damage with some wrong approaches. When faced with a bleeding condition, the patient and family should not panic and actively stop the bleeding by using the cleanest possible fabric available, such as gauze, towels, strips of cloth or clean clothing to press directly on the bleeding wound and then binding it with pressure using strips of fabric. When treating in this manner, do not use toilet paper, cotton, or other items that can easily break loose and be pressed directly on the wound, as this will shatter from contact with blood and will not be conducive to debridement during further treatment. The fabric used to compress the wound should be of sufficient thickness to allow more localized force to achieve the purpose of compressing the wound to stop bleeding. The force of compression should be moderate, and observe the tissue at the far end of the bandage: if there is pale hands, unsaturated fingers, and no filling after finger pressure whitening indicates no blood flow or poor blood flow, reduce the pressure appropriately. Do not use cloth, rope, wire, etc. to bind the near side of the injured hand, these inelastic ropes if used with insufficient force, will block the venous return of the injured limb, but can not block the arterial blood supply, the result is that the blood has a way to come without a way to go, can only flow from the wound, manifesting as more bleeding; if the binding is too strong, although it can block the blood flow, but the pressure on the local tissues is too strong, it will cause nerves, muscles, the blood vessels as well as irreversible damage to the skin. For active bleeding that cannot be stopped by compression hemostasis, it is important to rush to a nearby hospital as soon as possible. In critical situations, a wide elastic or non-elastic band may be temporarily wrapped around the muscle-rich area proximal to the wound by compression, recording the time, which should not exceed 30 minutes for one application. In short, do not panic, otherwise you will be busy and make mistakes. While bandaging, rush to a nearby hospital as soon as possible to give more professional disposition.
