14 - Bleeding / Soft Tissue Injuries Flashcards
Name the five blood vessels.
Arteries
Arterioles
Venules
Veins
Capillaries
The skin has two principal layers, name them.
Epidermis
Dermis
List three functions of the skin.
- Protects the body by keeping pathogens out and fluids in
- Helps regulate body temperature
- The nerves in the skin report to the brain on the environment and on many sensations (964)
The body will not tolerate an acute blood loss of greater than:
20%
The body has mechanisms in place to help control bleeding, list tw0 of these mechanisms:
- Vasoconstriction
- Coagulation (blood clotting)
(939)
What are three types of soft tissue injuries?
Closed soft-tissue injury
Open soft tissue injury
Burns
In a hot environment the vessels in the skin: In the cold environment the vessels in the skin:
HOT: Vessels expand to allow the body to sweat and cool down
COLD: Vessels constrict to preserve heat
Define these terms:
1. Melena
2. Hematemesis
3. Hemoptysis
Melena: Dark, sticky, stool
Hematemesis: Vomiting blood
Hemoptysis: Coughing blood
List three different methods to control external bleeding other than a tourniquet.
Direct pressure
Hemostatic dressing
Wound packing
Pressure dressings and / or splints
(944)
The brain and spinal cord can be injured after how many minutes without perfusion?
4 to 6 minutes
(937)
You are treating a 26 year old patient who has partial thickness burns on the anterior portion of both arms and the anterior portion of his right leg. What percentage of his body is burned?
Treatment:
4.5 + 4.5 + 9 = 18%
- remove burned clothing and jewelry
- Cover burns with dry sterile non adherent dressings
- High flow O2
- Treat for shock (SOBER) / hypothermia
- Rapid transport to burn center ER
A patient fell off her bike, landing on her left arm. There is a large amount of swelling in her forearm, and there is no pulse distal to the injury. The patient states the pain is a 15/10 on the pain scale and increases with movement. The S/S are most likely due to what condition?
Compartment syndrome
A 30-year-old patient is bleeding from a laceration to the lower leg. You are unable to control the bleeding with direct pressure and the patient is now showing signs of AMS. Your next action should be:
Apply a tourniquet above the wound and use a hemostatic dressing to cover
Treat for shock (SOBER)
Rapid transport to ER
In addition to external bleeding, the MOST significant risk of an open soft tissue injury is:
Infection
What are the two most important factors in determining the severity of a burn?
Depth
Extent
Exposure time
