1 15.3 Providing First Aid for Bleeding and Wounds
Pages LEQ: How does the type of wound determine the type of treatment provided?

2 Abrasion The surface and sometimes deeper layers of the skin is scraped off Bleeding is usually limited, but infection must be prevented because dirt and contaminants often enter the wound.

5 Incision This cut is caused by a sharp object such as a knife, scissors, or razor The edges are smooth and regular If the cut is deep, bleeding can be heavy and can lead to excessive blood loss and shock Damage to muscles, tendons, and nerves may also occur

9 Common Sutures

10 Staples

11 Lacerations Involves tearing of the tissues by way of excessive force
The wound is often has jagged or irregular edges Bleeding maybe heavy and if the wound is deep, it may lead to infection

14 Common Staples

15 Lacerations to the Cornea

16 Puncture Caused by a sharp object such as a pin, nail, or pointed instrument. External bleeding is limited, but internal bleeding can be severe Chance of infection especially tetanus is the tetanus bacteria has entered the wound

23 Avulsion Occurs when tissue is torn or ripped away from the victim’s body It can result in a piece being torn and hanging from the ear, nose, hand, or any other body part Bleeding is normally profuse It is important to preserve any body part while caring for the patient Wrap the body part in sterile gauze, wet it, bag it, and ice it * make sure it goes w/pt

29 Amputation Occurs when a body part is cut off or torn off
Bleeding can be extensive Care must be taken with the amputated object Wrap it in a cool moist dressing (use sterile water or saline if available) Place it in a plastic bag and then in ice water * Never place directly on ICE

33 Controlling Bleeding Shock and Death can occur quickly
Arterial : Bright Red and spurts out with pulse rate and must be controlled Venous : Dark Red or Maroon and is slower and easier to control Capillary : oozes out

34 CAUTION If possible, always use some protective barrier such as gloves or plastic wrap while controlling bleeding Use thick layers to avoid contact with your skin Wash your hands as soon as possible following the first aid

35 Controlling Bleeding 1st Use Direct Pressure (5-10 minutes) with a barrier and if it gets saturated, apply more bandage DO NOT TAKE THE FIRST BANDAGE OFF 2nd Elevation Raise the injured part above the level of the victim’s heart (If broken bones are suspected, do not elevate)

36 Controlling Bleeding 3rd Pressure Bandage Apply a pressure bandage making sure the knot is directly over the wound 4th Pressure Points You may apply pressure to the pressure points for a short period of time if bleeding persists (watch for failed circulation)

37 Pressure Points

38 INFECTION Can develop in any wound
Seek medical attention when S/S appear S/S: swelling, heat, redness, pain, fever, pus, and red streaks leading away from the wound

41 Tetanus Tetanus bacteria can enter any wound, but is most common in puncture wounds or wounds that involve damage to tissue under the skin Ask the patient when they last had their Tetanus shot or booster Wasp, Hornet, and sometimes Bee stings require a tetanus shot

42 Embedded Objects Splinters, small pieces of glass, or stones.
If it is on the surface, gently remove it with sterile tweezers or tweezers wiped clean with alcohol or a disinfectant Any deeper objects should be removed by a Physician

43 CLOSED WOUNDS Injuries that occur without breaking the skin. If a bruise occurs, cold application can be given to reduce swelling Internal Bleeding: pain, tenderness, swelling, deformity, cold and clammy skin, rapid and weak pulse, a drop in blood pressure, uncontrolled restlessness, excessive thirst, vomiting blood, or blood in the urine or feces. GET MEDICAL HELP IMMEDIATELY. Check breathing, S/S of shock, avoid unnecessary movement, and do not give fluids or foods

44 SHOCK Be prepared to treat shock while providing care to control bleeding and prevent infection to the wound At all times, remain calm while providing first aid. Reassure the victim and obtain appropriate assistance as soon as possible.
