Transcript

  • 1. Burr.....It’s getting cold out there An overview of cold emergencies and the treatment of them David B. Aber, NREMT-P
  • 2.  
  • 3. Myths about cold emergencies
    • It is very hard to break off a body part!!!!
    • If they are frozen….The whole “Warm and Dead” is out the door.
    • Homeless + Pulseless + Apenic does not =
    • “ BUMCICLE”
  • 4. What we will cover
    • Hypothermia
    • Frostbite
    • Treatments
    • Other goodies
  • 5. Hypothermia
    • Hypothermia is a condition in which an organism's temperature drops below that required for normal metabolism
    • But, when the body is exposed to cold, its internal mechanisms may be unable to replenish the heat that is being lost to the organism’s surroundings
  • 6. Risk Factors
    • Age
      • Old or young
    • Preexisting medical conditions
      • Anything that affects thermoregulation
    • Medications
      • Sedative Hypnotics (Valium)
    • Alcohol

    • Goose bumps form
      • Why?
    • Stage 1  Stage 2
      • If patient cannot touch pinky finger to thumb

    • Body temperature drops 4-8°F
    • Shivering becomes violent
    • Increased respirations
    • Confusion
    • Extremity cyanosis/Core paleness
  • 13. Stage 3
    • Body temperature drops to 89.6°F
    • Shivering stops
    • Slowing of speech
    • Below 89°F cellular metabolism stops
      • Blisters start to form
      • Terminal Burrowing
        • We will cover this later
  • 14. Frostbite
    • 3 Degrees as well
      • 1 st Frostnip
        • Not uncommon. Skin firm
      • 2 nd Superficial
        • Tissue hard to frozen feeling. Blue/White. Blistering
      • 3 rd Deep Frostbite
        • White Blotchy/Blue Skin
        • Severe cases/old appear black
        • Amputation/Grafting
  • 15. Frostbite
    • Why don’t we thaw frozen parts
      • Danger of refreezing
      • Cellular crystals grow bigger

  • 20. Cold water submersion
    • Mammalian Dive Reflex
    • Length of time in water

  • 23. In 1980, 16 shipwrecked Danish fishermen were hauled to safety after an hour and a half in the frigid North Sea. They then walked across the deck of the rescue ship, stepped below for a hot drink, and dropped dead, all 16 of them. - Peter Stark, Outside Magazine, 1997
  • 24. Terminal Burrowing
    • Last stages of hypothermia
    • Patients last attempts to get warm
    • Indoors
      • Closets, cupboards, any small enclosed space
    • Outdoors
      • Pile of leaves, between rocks, or fallen trees
  • 25. Paradoxical Undressing
    • Phenomenon that causes patients to undress in the mid to late stages of hypothermia
    • Not exactly sure why this happens
      • Malfunctioning hypothalamus
      • Sudden surge of blood making body feel hot
    • Study showed that in non wilderness conditions this sometime leads police to think of sexual assault
      • M. A. Rothschild et al., "Terminal burrowing behavior", p. 1
  • 26. Trench Foot
    • Nerve and tissue damage cause by cold and wet exposure
    • Numbness, redness, cyanosis
    • Blisters, open sores, gangrene
    • 60°F or less
    • 12 hours exposure

  • 28. Therapeutic Hypothermia
    • Sometime called “induced hypothermia”
    • Post resuscitated cardiac arrest patients
      • Delaware ALS and Hospitals are starting this
    • Studies show reduced mortality of 35%
    • Studies ongoing regarding use in ischemic strokes
  • 29. Therapeutic Hypothermia
  • 30.  
  • 31. EMS Treatments
    • Passive Rewarming
    • Using mainly the patients own body heat
    • Good for Mild Hypothermia
      • Blankets

      • Hot packs to groin, neck, armpits
      • Follow passive as well
      • Do not place Hot packs directly on frost bitten areas
  • 33. EMS Treatments
    • Warm water
    • Local protocols
    • Just above normal body temp 100-105°F
    • Kept/monitor a constant temperature of water
  • 34. EMS Treatments Blanket Warmers
  • 35. EMS Treatments Warmed Oxygen
    • Tubing through heating vents
  • 36. EMS Treatments Warmed Oxygen
    • Use of hot packs
  • 37. EMS Treatments Warmed Oxygen
    • *Commercial Wilderness device
    Activation Time Temperature Oxygen Flow (liters) 0 minutes 20° F 0 liters 1 minute 74.6° F 8 liters 5 minutes 82.3° F 8 liters 10 minutes 88.1° F 8 liters
