Bleeding, Shock, and soft-tissue injuries, Hemostatic agents (Chapter 14) Flashcards
Standard Precautions
- Wear gloves
- If appropriate, wear a surgical mask and eye protection
Shock
defined as failure of the circulatory system
Circulatory failure has many possible causes, but three primary causes are:
- Pump Failure
- Pipe Failure
- Fluid Loss
Pump Failure
- Cardiogenic Shock occurs if the heart cannot pump enough blood to supply the needs of the body
Results from a heart attack
Pipe failure
- caused by the expansion, constriction and ultimately the breakage of the vessel
-
Anaphylactic shock
- Rapid drop in blood pressure
- Spinal shock
-
Anaphylactic shock
Fluid Loss
- caused by excessive bleeding (hemorrhage) or loss of other body fluids
-
How do you know someone is bleeding?
- You can see, feel and smell it
-
How do you know someone is bleeding?
- Internal bleeding:
- Bruising
- Swelling
- Rigidity in the affected area
- Severe pain in the immediate area
An average adult has about _____ pints ( Liters) of blood circulating in the system
Loss of ______ or more pints can lead to shock
Someone experiencing Shocks feels ________
12pints (5.7 liters)
2 or more pints = shock
“impending doom”
General Treatment for ‘Shock’:
- Lay the person flat on his or her back on horizontal surface
- Control major bleeding
- Maintain the patients ABC’s
- Treat the causes of shock if possible
Maintain the patient’s body temperature
Controlling External Blood Loss:
Capillary Bleeding:
- Blood ooze outs
- most common type of blood loss
Venous Bleeding:
- Steady flow
- Direct pressure for at least 5 minutes
- second common type of blood type
Arterial Bleeding:
- Spurts or surges with each heartbeat
- Exert direct pressure and maintain pressure until EMS arrives
- Most serious type of bleeding
Tourniquets
indicated only in situations where extremity bleeding cannot be controlled by direct pressure or elevation
- Brachial, Femoral
- After applying, write TK and the time of application on the patient’s forehead (ex. TK: TIME)
- Rule of thumb: check for distal pulse (furthest away from tourniquet)
- *2-3 inches above the bleeding site*
- As tight as 3 fingers
Closed Wounds:
the only closed wound is the bruise (contusion)
Open Wounds:
- Abrasion —> scrape
- Puncture —> sharp object penetrates the skin
- Laceration —> cut
Avulsions / amputations —> tearing away of body tissue / entire body part is torn away
Dressing and Bandaging Wounds
- Control bleeding
- Prevent further contamination
- Immobilize the injured part
- Prevent movement of impaled objects
Dressing
VS
Bandaging
Dressing - an object placed directly on the wound (never remove dressing)
Bandaging- used to hold the dressing in place
Burn Depth:
superficial burns
partial-thickness burns
Full-Thickness burns
1st degree burns
2nd degree burns
3rd degree burns
