  5. Sedation and pain management - In order to provide appropriate long term airway management adequate knowledge and skills to provide sedation and analgesia are required

Q

Tourniquet Conversions

If a TQ is in place for > 6 hours should you attempt conversion?

A

Not advised in PFC

18
Q

What is the fluid of choice for patients in hemorrhagic shock?

A

Fresh Whole Blood (FWB)

19
Q

What is the best fluid in PFC?

A

THE BEST FLUID IN PFC IS THE ONE YOU HAVE AVAILABLE

20
Q

What is a very easy tool available to monitor the patient’s response and guide resuscitative efforts?

A

Urine Output (UOP)

21
Q

What is the goal for adequate UOP?

A

0.5-1mg/kg/hr

Reflects adequate kidney perfusion and volume

22
Q

What is fluid therapy given to achieve adequate end organ function?

A

Resuscitation fluid

23
Q

What is fluid therapy that corrects water/electrolyte deficits due to pathologic volume loss, usually given as continuous IV infusion (loss from burns, GI illness, head trauma, DI, chock) ?

A

Replacement fluid

24
Q

What fluid therapy is given as nutrition to provide water/electrolytes lost via ongoing sweat, urination, stool output as well as glucose required mainly for brain metabolism?

A

Maintenance fluid

25
Q

What are made of large molecules that attract fluid into the intravascular space from interstitium?

A

Colloids

26
Q

____ml of Hetastarch (common colloid) will give an approximate equivalent volume of 2000ml of NS?

A

500ml

27
Q

True or False

Colloids can be used as maintenance fluids

A

No role for colloids in maintenance fluids as there is a potential risk of complications including kidney disease and induced coagulopathy

28
Q

What are some general colloid recommendations?

A
  1. Initial volume expansion in hemorrhagic shock while provision of blood is being arranged
  2. Resuscitation of perfusion to dysfunctional organs or unstable hemodynamics in non-hemorrhagic shock states
  3. Reducing crystalloid requirements in burn patients at risk for over resuscitation, and peripheral or abdominal compartment syndromes
29
Q

What fluids work to expand intravascular volume, however only approximately 25% remain within vasculature at 1 hour therefore when given as a resuscitation fluid large volume bolus is required?

A

Crystalloids

30
Q

Continuous infusion of ____ are likely to diffuse out into the “third space”

A

Crystalloids

31
Q

What are some complications of large volume crystalloid resuscitation?

A
  1. Compartment syndrome
  2. Acute respiratory distress syndrome
  3. Dilutional coagulopathy
  4. Acidosis
32
Q

Caution should be used with crystalloids, NS is an unbalanced fluids with a supraphysiologic concentration of chloride therefore can produce _____, this can worsen inflammation and decrease kidney function.

A

Hypercholremic Metabolic acidosis

33
Q

Fresh whole blood (FWB) is the fluid of choice for patients in hemorrhagic shock; to mitigate the risks in PFC the recommendations include what?

A
  1. MAP of 65mmHg
  2. Adequate UOP (at least 0.5cc/kg/hr)
  3. Adequate mentation
34
Q

If the patient is UNSTABLE with inadequate intravascular volume, resuscitate with what?

A

Bolus fluids

35
Q

If the patient is STABLE with adequate intravascular volume, use what?

A

Maintenance fluid

General target is to achieve a urine output of at least 0.5ml/kg/hr

36
Q

A reasonable formulary of “working drugs” for the IDC should include what?

A
  1. Morphine
  2. Fentanyl
  3. Ketamine
  4. Midazolam (Versed)
  5. Adjunctive medications:
    a. Narcan
    b. Romazicon
    c. Antiemetics (zofran)
    d. Antihistamines (Claritin, Zyrtec, or Benadryl)
    e. Atropine
    f. Epinephrine
37
Q

What are medications given which produce a diminished sensation to pain without producing a loss of consciousness?

A

Analgesic medications

38
Q

What is the depression o a patient’s awareness to the environment and reduction of responsiveness, various levels include minimal, moderate, and deep?

A

Sedation

39
Q

True or False

Stable patients can get Morphine. Hemodynamically unstable patients should
get Fentanyl (or Ketamine).
A

True

40
Q

What is the dosage of ketamine for low dose pain?

A

10-20mg IV titrate to effect repeating dose every 10 minutes as needed for desired effect

41
Q

What is the ketamine dosage for a patient in High pain dose and they are dissociative?

A

2.0 mg/kg IV and should also include Versed to avoid vivid dreams which can lead to lifelong dreams and PTSD.

42
Q

What medication as synergistic effects with opioids and Ketamine and can cause over-sedation, respiratory compromise and drop in BP?

A

Versed
