Traumatic bleeding

Introduction Traumatic bleeding can be divided into external bleeding and internal bleeding. Blood flowing from the wound to the outside of the body is called external bleeding, which is common in knife cuts, stab wounds, bullet wounds and smashing injuries. If the skin has no wounds, the blood flows from the ruptured blood vessels into the tissues, organs or body cavities, called internal bleeding. The cause of internal bleeding is far more complicated than external bleeding, and the treatment is more difficult. It is necessary to go to the hospital for treatment. Treatment of traumatic hemorrhage: capillary bleeding: blood seeps from the wound or around the wound, the amount of bleeding is small, the color is red, no obvious bleeding point can be found, and the risk is small. This bleeding can often stop automatically. After disinfecting the skin around the wound with iodine and alcohol, disinfect the gauze or clean handkerchief and cloth on the wound cover and tighten it to stop bleeding. Venous hemorrhage: dark red blood that slowly and continuously flows out of the wound, and then the blood flow gradually slows down due to local vasoconstriction, and the risk is also small. The method of stopping bleeding is basically the same as that of capillary bleeding. Raising the affected limb can reduce bleeding. For example, put a few layers of sterile gauze or clean handkerchief on the bleeding site, and pressurize the dressing to achieve the purpose of stopping bleeding.

Cause

Causes of traumatic bleeding: common in knife cuts, stab wounds, gunshot wounds and crushing injuries. First aid in arterial bleeding, usually by indirect acupressure to stop bleeding. That is, at the proximal end of the bleeding artery, the thumb and the rest of the fingers are pressed against the bone surface to stop bleeding. In the direction of the artery, the most easily pressed part is called the point of compression, and it is necessary to be familiar with the compression point of the main artery when hemostasis. This method is simple and easy, but because the fingers are prone to fatigue and can not last, it can only be a temporary emergency hemostasis, and must be replaced by other methods as soon as possible.

Diagnosis of traumatic bleeding:

1. According to whether the patient has a history of trauma.

2. Use X-ray auxiliary examination and diagnosis.

Traumatic bleeding can be divided into external bleeding and internal bleeding. The differential diagnosis should be clear.

1. The blood flowing from the wound to the outside of the body is called external hemorrhage, which is common in knife cuts, stab wounds, bullet wounds and bruises.

2. If the skin has no wounds, the blood flows from the ruptured blood vessels into the tissues, organs or body cavities, called internal bleeding. The cause of internal bleeding is far more complicated than external bleeding, and the treatment is more difficult. It is necessary to go to the hospital for treatment.
