Bleeding, soft tissue injuries and shock

Introduction•Bleeding is the escape of blood from the arteries, capillaries or veins and can occur internally or externally.

•Uncontrolled bleeding, whether internal or external, is life threatening.

•How much is too much to lose?? 2 pints is a critical loss

Protect against disease.

Maintain constant body temperature.

• Three major types of blood vessels Arteries

Capillaries

Veins.

External Bleeding

Each type of blood vessel bleeds differently.

•Arterial bleeding is rapid and, if severe, is life threatening. The blood is bright red in color.

•Venous blood is under less pressure and flows from the wound at a steady rate. The blood is dark red in color.

•Capillary bleeding is usually slow because the vessels are small. Blood oozes from the wound.

Caring for External Bleeding

• Check-Call-Care

• Care:• Elevate the bleeding part• Apply direct pressure to the wound with a gloved hand• If bleeding is severe, lay the person down and elevate the

site of bleeding• Remove any obvious debris or dirt from the wound• Don’t remove any object pierced into the victim.

• To apply pressure directly to the wound wear gloves and use a sterile dressing, clean cloth or even a piece of clothing. If nothing else is available, use your gloved hand.

•Maintain pressure until the bleeding stops. When it does, bind the wound tightly with adhesive tape or a bandage. If none is available, use a piece of clean clothing.

• If the bleeding continues and seeps through the gauze or other material you are holding on the wound, do not remove it. Instead, add more absorbent material on top of it.

• Immobilize the injured body part once the bleeding has been stopped. Leave the bandages in place and get the injured person to the emergency room as soon as possible or, if they cannot be moved, call 911

Internal bleeding• The escape of blood from arteries, veins or capillaries into

spaces within the body.

• Can occur from injuries caused by blunt force or a chronic medical condition.

• Can also occur when an object penetrates the skin and damages internal structures.

• You should suspect internal bleeding in any serious injury.

Care for Internal Bleeding• Check-Call-Care

• Care:• For minor internal bleeding, such as bruising, apply ice.

• If you suspect severe internal bleeding, call 9-1-1 immediately.

• Then follow these general care steps to prevent shock: Do no further harm.

Monitor signs of life and consciousness.

Shock•A progressive condition in which the circulatory system

fails to circulate oxygen-rich blood to all parts of the body.

•When the body is unable to meet its demand for oxygen because blood fails to circulate adequately, shock occurs.

Causes of Shock • Physical or psychological Trauma can cause shock.

•Other causes/Types of shock can include:▫ Allergic reaction

(Anaphylactic)

▫ Hemorrhage (hemorrhagic)

▫ Infection (septic)

▫ Heart attack (Cardiogenic)

▫ Poison (Toxic)

Signals of Shock•Without intervention, the body’s failed attempt to

compensate for blood loss eventually will result in death.

• Signals of shock include (very similar to internal bleeding signals)—Restlessness or irritability. Altered consciousness.Pale or ashen, bluish, cool or moist skin.Rapid breathing.Rapid and weak pulse.Excessive thirst.Nausea and vomiting.

Care for Shock• CHECK—CALL—CARE

•To care for shock—Keep the victim calmKeep the victim warmElevate the legs about 12 inches to help blood circulate to

the vital organs.Do not elevate the legs if —

The victim is nauseated or having trouble breathing. You suspect head, neck or back injuries or possible broken bones. Moving causes more pain.

Soft tissue injuries/wounds

•A wound is an injury that damages the body’s tissues.

Types of open wounds

•Abrasion

• Incision

• Laceration

• Puncture

•Avulsion

•Amputation

Abrasion

• In this type of wound, the skin is scraped off.

• Bleeding is limited.

• Infection must be prevented due to contamination by dirt.

Incision• A cut or injury caused by a sharp

object such as a knife or razor.

• Edges of the wound are smooth and regular.

• Bleeding can be heavy.

• May damage muscles and nerves.

Laceration• Tearing of the tissues by way of

excessive force.

• The wound has jagged, irregular edges.

• Bleeding may be heavy.

• Wound may be contaminated leading to infection.

Puncture• Caused by a sharp object such as

a pin or nail.

• Limited external bleeding, but may bleed internally.

• Increased risk for infection, For ex: tetanus.

Avulsion• Tissue is torn or separated from the

patient’s body.

• Bleeding is heavy and extensive.

• Preserve the avulsed body part for possible surgical reattachment.

Amputation

•Occurs when a body part is cut off and separated from the body.

•Bleeding is heavy and extensive.

•Preserve the body part in a cool, moist dressing (don’t place directly on ice).

Dressings and Bandages

•A dressing is a pad placed directly over a wound to absorb blood and other body fluids and to prevent infection.

•A bandage is any material used to wrap or cover any part of the body.

Dressings

• Dressings are used to:▫stop bleeding

▫prevent infection

▫absorb secretions

▫treat pain

• Gauze pads are the most common materials used for dressings. However, in an emergency situation, any clean cloth can be used.

Bandages

• Bandages should be tight enough to control bleeding and to hold a dressing in place. However, they should not interrupt blood circulation.

• Three popular types of bandages are:

▫Roller gauze

▫Elastic

▫Triangular

Dressings and Bandages (continued)

•To apply an elastic or

roller gauze bandage—•Check feeling, warmth and color.•Secure the end of the bandage.•Do not cover fingers or toes.• If blood soaks through the dressings, do not

remove them. Apply additional dressings and another bandage.
