Heat
Pus
Red streaks coming from the woundSlide4
Types of wounds - Closed
Wounds
A closed wound is an injury that causes damage to the tissue under the skin.
Closed wounds are caused when the body hits against a blunt object, such as in a bump or fall.
A
closed wound will usually heal on
its own
in a few weeks
.
Contusion
- bruise
Hematoma
- also called blood tumors or blood blisters, caused by damage to a vessel that causes blood to collect under the skin.
Internal
-
caused by crushing injury to the bodySlide5
Types of Wounds - Open
Wounds
Incisions
Lacerations
Abrasions
Punctures
Avulsions
AmputationsSlide6
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 occurSlide7
Laceration
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 infectionSlide8
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.Slide9
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 woundSlide10
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 patientSlide11
Amputations
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 waterSlide12
Minor Open Wounds
Minor wounds are shallow and produce very little blood.
They are not life-threatening and can be treated at home.
Untreated, or improperly treated, minor wounds can become infected or can cause tetanus Slide13
Major Open Wounds
It is important to act quickly when treating a patient with a major wound because a patient can bleed to death in a short period of time
Care for a major wound includes stopping the bleeding and then cleaning and covering.
When caring for major wounds, the health care worker should also check the patient’s vital signs, and watch for signs of shock. Slide14
Dressings
A dressing is a sterile covering for a wound or injury.
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. Slide15
Bandages
A bandage is material used to secure dressings and splints.
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:
Triangular
Roller gauze
Elastic
