1. Bleeding, Wounds, and Soft Tissue Injuries Presence Regional EMS System August 2014 C.E.

2. Objectives • Describe the characteristics of external bleeding including differentiation between arterial, venous, and capillary bleeding • Identify signs and symptoms of significant bleeding, including internal bleeding

3. Objectives • Explain the use of traditional and new innovative means of managing external bleeding • Describe the management of avulsions and amputations • Define a significant crush injury • Outline the management of patients who have sustained a significant crush injury

4. Maintain Standard Precautions When Dealing with Body Substances!

5. Cardiovascular System Overview • The cardiovascular system is an organ system that allows for the circulation of blood to cells and tissues, the delivery of oxygen and nutrients, and the removal of waste products.

6. Parts of the Cardiovascular System • Heart: The hollow organ that pumps blood throughout the body. • The right side receives deoxygenated blood from the body and pumps it into the lungs • The left side receives oxygenated blood from the lungs and pumps it to the tissues of the body

7. Parts of the Cardiovascular SystemBlood Vessels • Arteries • Small blood vessels that carry blood away from the heart • Arterioles • Smaller vessels that connect the arteries and capillaries

8. Parts of the Cardiovascular SystemBlood Vessels • Capillaries • Small tubes that link arterioles and venules • Capillary beds are where the exchange of nutrients and wastes take place • Venules • Very small, thin-walled vessels that empty into the veins • Veins • Blood vessels that carry blood from the tissues to the heart

9. Parts of the Cardiovascular SystemComponents of Blood • Red blood cells • Responsible for the transportation of oxygen to the cells • Responsible for transporting carbon dioxide away from the cells to the lungs • White blood cells • Cells of the immune system that function to protect the body from foreign materials and infectious disease

10. Parts of the Cardiovascular SystemComponents of Blood • Platelets • Responsible for forming clots • A blood clot forms depending on blood stasis, changes in the vessel walls, and the body’s ability to clot. • Plasma • Liquid component of blood that holds the blood cells in suspension

11. Why is this important? • All organs of the body rely on the cardiovascular system to deliver oxygen and nutrients • Bleeding causes hypoperfusion • The death of an organ system due to lack of perfusion can lead to the death of the patient

12. Some organ systems can survive without perfusion for a limited period of time: • Brain and spinal cord may last 4 to 6 minutes. • Kidneys may survive 45 minutes. • Skeletal muscles may last 2 hours. • Times are based on a normal body temperature. • The heart requires constant perfusion in order to survive

13. External Bleeding • With serious external bleeding, it may be difficult to determine the amount of blood loss. • Presentation and assessment of the patient will direct care and treatment. • Body will not tolerate a blood loss greater than 20% of it’s blood volume.

14. Use familiar measurements to estimate blood loss

15. Significant changes in vital signs may occur if the typical adult loses more than 1 L of blood. • Increase in heart rate • Increase in respiratory rate • Decrease in blood pressure • SHOCK

16. Serious conditions with bleeding: • Significant MOI • Patient has a poor general appearance and is calm. • Signs and symptoms of shock • Significant blood loss • Rapid blood loss • Uncontrollable bleeding

17. Characteristics of External Bleeding • Arterial bleeding • Pressure causes blood to spurt and makes bleeding difficult to control. • Typically brighter red and spurts in time with the pulse • Venous bleeding • Dark red, flows slowly or severely • Does not spurt and is easier to manage

18. Capillary bleeding • Bleeding from damaged capillary vessels • Dark red, oozes steadily but slowly Capillary Venous Arterial

19. Internal Bleeding • Bleeding in a cavity or space inside the body • Can be very serious • Outward signs can be deceiving • Injury or damage to internal organs can result in excessive internal bleeding • Can cause hypovolemic shock even though there is no fluid loss outside of the body

20. Internal Bleeding • Signs of internal bleeding • High-energy Mechanism of Injury • Pain • Swelling in the area of bleeding • Distention • Bruising • Dyspnea, Tachycardia, Hypotension • Hematoma • Bleeding from any body opening

21. Assessing for Bleeding • Use DCAP-BLS-TIC to assess for traumatic injuries • Deformities • Contusion • Abrasions • Puncture/Penetrations/Paradoxical Movement • Burns • Lacerations • Swelling • Tenderness • Instability • Crepitus

22. Identify Bleeding • Identify life threatening external bleeding • Assessed during the ‘Circulation phase’ of your initial assessment • Identify bleeding that is uncontrolled or bleeding with significant fluid loss • Attempt to control life threatening bleeding as you find it!

23. Identify Shock • Hypovolemic Shock is due to fluid loss outside of the system; results in hypoperfusion • Early detection and identification of shock is paramount to patient survival • SKINS DO NOT LIE

24. Signs of Shock • Compensated Shock (Early Stage) • Anxiety • Altered mental status • Weak, rapid pulse • Pale, cool, and moist skin • Shallow, rapid breathing • Nausea and/or vomiting

25. Signs of Shock • Decompensated Shock (Late Stage) • Systolic Blood Pressure less than 90 in adults • Labored or irregular breathing • Ashen, mottled, or cyanotic skin • Thready or absent peripheral pulses • Dull eyes with dilated pupils • Poor skin turgor

26. How to Control External Bleeding • Direct Pressure • Elevation • Pressure Dressings/Splints • Tourniquets

27. Direct Pressure • Most effective way to control external bleeding • Pressure stops the flow of blood and permits normal coagulation to occur. • Apply pressure with your gloved fingertip or hand over the top of a sterile dressing • Hold uninterrupted pressure for at least 5 minutes

28. Elevation • Elevate a bleeding extremity by as little as 6" while applying direct pressure. • Never elevate an open fracture to control bleeding. • Fractures can be elevated after splinting. • Splinting helps control bleeding.

29. Pressure Dressing • Firmly wrap a sterile, self-adhering roller bandage around the entire wound. • Cover the entire dressing above and below the wound. • Stretch the bandage tight enough to control bleeding. • You should still be able to palpate a distal pulse • Do not remove without a physician present

30. Tourniquet • If direct pressure fails, apply a tourniquet above the level of bleeding. • It should be applied quickly and not released until a physician is present. • Never use a tourniquet over a joint • Pad below the tourniquet • Use only proper equipment; i.e. a commercial tourniquet • Document the date/time the tourniquet was placed

31. Hemostatic Agents • Hemostatic agents are used to promote the body’s natural clotting abilities • For uncontrollable bleeding • Unable to use tourniquet (groin, axilla, neck) • Used in conjunction with direct pressure and pressure dressings • Be mindful of local protocols regarding their use

32. Internal Bleeding • Identify internal bleeding and initiate rapid transport • Control cervical spine through use of Spinal Motion Restriction • Control fractures with splinting • Internal bleeding requires surgery – Do not delay transport!

33. Avulsions • An injury that separates various layers of soft tissue • Treat by placing partially separated piece back into original location and covering with sterile gauze • Be careful to make sure the site is free of debris • Wrap pieces that have been completely removed in sterile gauze and transport with patient

34. Avulsions • Avulsions involving large areas of tissue may cause large amounts of bleeding • Never remove an avulsion skin flap, regardless of size!

35. Amputations • An injury in which part of the body is completely severed • Includes both incomplete and complete amputations • A complete amputation involves an extremity that has been completely removed from the body • An incomplete amputation involves an extremity that is still attached to the body by a small amount of tissue

36. Amputations • Attempt to control bleeding via direct pressure over the stump • If bleeding cannot be controlled by direct pressure, apply a commercial tourniquet proximal to the amputation • Amputation extremities can possibly be saved by a surgical team

37. Amputation • Note incomplete amputation to the right leg on image • Note complete amputation to the left leg on image

38. Amputation • DO NOT delay care in order to retrieve entrapped or lost part • DO NOT complete an incomplete amputation FR/BLS TREATMENT: • INITIAL TRAUMA CARE. • Treat for shock if indicated. • Tissue Preservation: • Rinse part gently with normal saline if gross contamination (DO NOT SCRUB) • Wrap part in moist sterile gauze (part should never be immersed in water). • Place wrapped part in water tight bag and seal. • Label bag with name, date and time. • Place sealed bag into container filled with water and ice and transport with patient.(DO NOT PLACE DIRECTLY ON ICE)

39. Amputation Call for intercept per INTERCEPT CRITERIA. • ALS may administer pain medications following Region 6 protocols.

40. Crush Injury • Pressure on extremities for extended time • Disrupts blood flow • Promotes anaerobic metabolism • Pressure released • Blood flow to crushed tissue reinstated • Toxins distributed throughout entire body • May induce cardiac dysrhythmia and severe kidney damage • “Crush or Compression Syndrome”

41. Examples of Crush Injuries • Hand trapped in an industrial roller • Foot caught in railroad tracks • Lower extremities caught between a car and a wall • Arm caught between two large rocks

42. Management of Crush Injuries • Perform frequent ongoing exams • Alkalizing the blood • Fluid resuscitation – large volumes • NaCO3 infusion • Osmotic diuretics • If administration of fluids or medications prior to releasing the entrapped body area is not possible, consider application of a tourniquet proximal to the injury site. • Contact Medical Control early; follow local protocols regarding treatment of crush injuries
