A little about me….
Everything I need to know I
     learned in EMS
Call #1
You arrive at the fire house at 6am for your day
  shift and start checking out the back of your
  truck. You finish re-stocking and just as
  everyone is about to sit down to scrambled
  eggs and coffee, the tones go out for your first
  call of the day…

―Please respond to the Bank of America for the
  person with altered mental status‖
Everything I need to know I learned
in EMS

 Stop for coffee before
    you get to work.
Call #1
   You and your partner hop in the truck and
    respond down to the BOA. You are met on
    arrival by the Police Lt. who tells you ―We got
    called for this guy because he was trying to
    break into an ATM. He’s been acting really
    weird…I think something is wrong with him‖.
Call #1
   Convinced that this is either a turf job or a
    case of acute incarceritis, you grab your
    equipment and approach your patient, who is
    sitting, handcuffed, on the curb in front of the
    bank.
Call #1
At first glance:
 Male in his 30s

 Looks agitated, disheveled, sweaty

 Tells you he was not trying to steal the ATM, it

  was ―his ATM‖ which he ―invented and built
  himself‖ because he is ―the smartest person in
  the world‖. He is speaking very fast.
Call #1

   Bloodshot eyes
   Pupils look like saucers

He agrees to let you take his vitals:
BP 180/100, HR 110, RR 28, O2 Sat 98%RA
Call #1
   While you are taking his BP, you notice track
    marks. He starts yelling about wanting to make
    a ―complaint against the f&%$ing cops‖ for
    beating him up. He says they punched him in
    the chest and now it hurts.
   You ask if he uses drugs– ―No, I don’t do that
    stuff‖
Everything I need to know I learned
in EMS

          People lie
Call #1
    Now what?
a)    Turf him back to the police. This guy is just
      high and your coffee is waiting for you.
b)    Have him sign a refusal, he is only
      complaining of chest pain because he wants
      to file a lawsuit against the PD.
c)    Do a quick PE & EKG to cover your butt.

Learned in EMS



  Crack is Whack.
Call #1
    Now what?
a)    O2, fluids, & cool him

Call #2
   You just finished your report from the last
    patient you dropped off at the hospital and as
    you are standing in the ambulance bay trying
    to explain what an awful awful is to the Kent
    resident riding along with you, your radio goes
    off…

―Please respond to the private residence for the
 question of an overdose‖
Call #2
   You respond to the scene where you are
    frantically being flagged down by a woman
    standing outside a three family home. As you
    get out of your truck she is yelling, ―HURRY!!
    She took some pills…I think she is really sick!‖

    You and your partner grab your equipment and
    are lead up to the 3rd floor.
Everything I need to Know I
learned in EMS

Patients who need to be
 carried live on the top floor.
Healthy, ambulating patients
 live on the bottom floor.
Call #2
   You are lead to a back bedroom where you
    find a woman in her 20’s laying on a bed,
    semi-conscious, with an empty pill bottle next
    to her. You ask her friend what happened…

―I’m not sure, I don’t really know her…she said
   she wanted to kill herself‖

    You yell ―Ma’am, wake up‖ but she does not open
     her eyes
Call #2
   You give her a sternal rub. She pushes your
    hand away and opens her eyes. You ask her
    what happened and she mumbles, ―Leave me
    the hell alone and let me die‖ and then closes
    her eyes again.
Call #2

          •Prolonged QRS
          •Prolonged QT
Call # 2
   You put the patient on oxygen, secure her to
    your stair chair and begin extrication. While
    you and your partner are carrying her down
    the stairs, you try to remember what it was that
    you learned about overdoses with prolonged
    QRS complexes in rescue rounds…

                  And then she starts to seize
Tricyclic Antidepressants
   So named because of their shape
   Used to treat:
     Depression

     ADD

     Anxiety

   Examples:
     Amitriptyline

     Nortriptyline
Tricyclic Antidepressants
   How they work:
     Block the reuptake of Serotonin & Norepi in the
      central nervous system (SNRI)
     These neurotransmitters make us feel happy and
      focused




       But in large quantities can cause delirium, seizures
Tricyclic Antidepressants
   4 major effects of TCA OD:
     Anticholinergic
    α  adrenergic blockade
     Inhibits Norepi reuptake

     Na+ channel blockade

  • 6. Call #1 You arrive at the fire house at 6am for your day shift and start checking out the back of your truck. You finish re-stocking and just as everyone is about to sit down to scrambled eggs and coffee, the tones go out for your first call of the day… ―Please respond to the Bank of America for the person with altered mental status‖
  • 7. Everything I need to know I learned in EMS Stop for coffee before you get to work.
  • 8. Call #1  You and your partner hop in the truck and respond down to the BOA. You are met on arrival by the Police Lt. who tells you ―We got called for this guy because he was trying to break into an ATM. He’s been acting really weird…I think something is wrong with him‖.
  • 9. Call #1  Convinced that this is either a turf job or a case of acute incarceritis, you grab your equipment and approach your patient, who is sitting, handcuffed, on the curb in front of the bank.
  • 10. Call #1 At first glance:  Male in his 30s  Looks agitated, disheveled, sweaty  Tells you he was not trying to steal the ATM, it was ―his ATM‖ which he ―invented and built himself‖ because he is ―the smartest person in the world‖. He is speaking very fast.
  • 11. Call #1  Bloodshot eyes  Pupils look like saucers He agrees to let you take his vitals: BP 180/100, HR 110, RR 28, O2 Sat 98%RA
  • 12. Call #1  While you are taking his BP, you notice track marks. He starts yelling about wanting to make a ―complaint against the f&%$ing cops‖ for beating him up. He says they punched him in the chest and now it hurts.  You ask if he uses drugs– ―No, I don’t do that stuff‖
  • 13. Everything I need to know I learned in EMS People lie
  • 14. Call #1  Now what? a) Turf him back to the police. This guy is just high and your coffee is waiting for you. b) Have him sign a refusal, he is only complaining of chest pain because he wants to file a lawsuit against the PD. c) Do a quick PE & EKG to cover your butt.
  • 15. Call #1  Now what? a) Turf him back to the police. This guy is just high and your coffee is waiting for you. b) Have him sign a refusal, he is only complaining of chest pain because he wants to file a lawsuit against the PD. c) Do a quick PE & EKG to cover your butt.

  • 31. Cocaine  Cocaine induced chest pain  ↑HR, ↑oxygen demand of the heart  Vasoconstrictioncoronary artery spasmCP  Chronic cocaine use can increase atherogenesisthrombus formatonCP  Consider the cath lab in STEMI  DO NOT GIVE βblockers
  • 32. Sympathetic NS EPI/NE α β - Constriction of blood vessels - increased heart rate -increased heart contractility -relaxation of smooth muscle in lungs - relaxation of blood vessels
  • 33. Sympathetic NS EPI/NE α β - Constriction of blood vessels - increased heart rate -increased heart contractility -relaxation of smooth muscle in lungs - relaxation of blood vessels *you can use Phentolamine, which is a direct α blocker
  • 34. Treatment ABC
  • 35. Treatment  Hyperthermia  Get those shears out  Cold packs  HTN/Tachycardia/Delirium/Seizures  BENZOS!!!!!  Diazepam 10mg q5min  Lorazepam 1mg q5min  Chest pain/Ischemic EKG changes  MONA  NTG will also help with HTN
  • 36. Call #2  You just finished your report from the last patient you dropped off at the hospital and as you are standing in the ambulance bay trying to explain what an awful awful is to the Kent resident riding along with you, your radio goes off… ―Please respond to the private residence for the question of an overdose‖

  • 47. Call #2 •Right Axis deviation •Prolonged QRS •Prolonged QT
  • 48. Call # 2  You put the patient on oxygen, secure her to your stair chair and begin extrication. While you and your partner are carrying her down the stairs, you try to remember what it was that you learned about overdoses with prolonged QRS complexes in rescue rounds… And then she starts to seize
  • 49. Tricyclic Antidepressants  So named because of their shape  Used to treat:  Depression  ADD  Anxiety  Examples:  Amitriptyline  Nortriptyline
  • 50. Tricyclic Antidepressants  How they work:  Block the reuptake of Serotonin & Norepi in the central nervous system (SNRI)  These neurotransmitters make us feel happy and focused  But in large quantities can cause delirium, seizures
