Treatment

First aid, Emergency Bleeding Control

Minor bleeding

Minor bleeding is bleeding that falls under a Class I hemorrhage and the bleeding is easily stopped with pressure.

The largest danger in a minor wound is infection. Bleeding can be stopped with direct pressure and elevation, and the wound should be washed well with soap and water. A dressing, typically made of gauze, should be applied. Peroxide or iodine solutions (such as Betadine) can injure the cells that promote healing and may actually impair proper wound healing and delay closure.

Bleeding from body cavities

The only minor situation is a spontaneous nosebleed, or a nosebleed caused by a slight trauma (such as a child putting his finger in his nose).

Simultaneous externalised bleeding from the ear may indicate brain trauma if there has been a serious head injury. Loss of consciousness, amnesia, or fall from a height increases the likelihood that there has been a severe injury. This type of injury can also be found in motor vehicle accidents associated with death or severe injury to other passengers.

Hemoptysis, or coughing up blood, may be a sign that the person is at risk for serious bleeding. This is especially the case for patients with cancer. Hematemesis is vomiting up blood from the stomach. Often, the source of bleeding is difficult to distinguish and usually requires detailed assessment by an emergency physician.

Internal bleeding

Main article: Internal bleeding

Internal bleeding occurs entirely within the confines of the body and can be caused by a medical condition (such as aortic aneurysm) or by trauma. Symptoms of internal bleeding include pale, clammy skin, an increased heart rate and a stupor or confused state.

The most recognizable form of internal bleeding is the contusion or bruise.

Risk of blood contamination

Because skin is watertight, there is no immediate risk of infection to the aide from contact with blood, provided the exposed area has not been previously wounded or diseased. Before any further activity (especially eating, drinking, touching the eyes, the mouth or the nose), the skin should be thoroughly cleaned in order to avoid cross contamination.

To avoid any risk, the hands can be prevented from contact with a glove (mostly latex or nitrile rubber), or an improvised method such as a plastic bag or a cloth. This is taught as important part of protecting the rescuer in most first aid protocols.

Following contact with blood, some rescuers may choose to go to the emergency department, where post-exposure prophylaxis can be started to prevent blood-borne infection.

As a medical treatment

Before the advent of modern medicine the technique of bloodletting, or phlebotomy, was used for a number of conditions: causing bleeding intentionally to remove a controlled amount of excess or "bad" blood. Phlebotomy is still used as an extremely effective treatment for Haemochromatosis.
