Q

Clinical Features of ICU-AW

A

1) Weakness devo after onset of critical illness
2) Weakness involving proximal & distal muscles, limbs, & respiratory muscles
3) Spares CN’s
4) MRC score <48/60
5) Dependency on vent
6) Weakness is not related to any underlying critical illness

*Need to have 1,2, & 6, &/or 4 & 5

18
Q

What are important mechanisms for ICU-AW-associated weakness & why?

A

Immobility & inflammation–>Shift of pro-inflammatory cytokines during critical illness leads to incr systemic infection which causes further muscle damage

*This combined w/production of reactive O2 species (ROS) w/incr anti-oxidative defenses causes further disruption between muscle synthesis & proteolysis

Q

How much of a decrease in strength can ICU-AW pt’s see in the first week?

A

40% decrease

21
Q

How much of a decrease in strength can pt’s w/disuse atrophy see in the first week?

A

5% decrease

22
Q

What is disuse atrophy associated with?

A

Structural & metabolic changes of muscle:

  * Net loss of muscle mass &amp; CSMA
  * Decr contractile strength
  * Shift from slow twitch to fast twitch fibers
23
Q

Complications associated w/ICU-AW & VIDD

A
  • Incr time on a vent
  • Muscle weakness ranging from mild to paralysis
  • Adverse effects to the diaphragm
  • Hypoglycemia
  • Muscle Atrophy
  • Muscle fiber shift to type 2
  • Protein loss & malnutrition
  • Anabolic resistance
24
Q

VIDD

A

Ventilator Induced Diaphragmatic Dysfunction

25
Q

What can hypoglycemia cause & why?

A

Decr diaphragmatic strength bc of oxidative stress & decr troponin

26
Q

Risk factors for ICU-AW

A
  • Vent >7days
  • Sepsis
  • Multi Organ Failure
  • Hyperglycemia
  • Systemic Inflammatory Response Syndrome
  • Corticosteroid Use
  • Neuromuscular blockers
  • Muscle immobilization
27
Q

What is prolonged mechanical ventilation associated w/?

A
  • Incr oxidative stress
  • Oxidative modifications to diaphragmatic proteins
  • Upregulation of autophagic system
  • Activation of proteolytic pathways
  • Muscle atrophy
28
Q

Delirium

A

Brain dysfxn characterized by acute disturbance of consciousness w/inattention, disorganized thinking, & perceptual disturbances that fluctuate over a short period of time

29
Q

Hypoactive Delirium

A

Lethargy & inattention

30
Q

Hyperactive Delirium

A

Agitated & combative

31
Q

Mixed Delirium

A

*

32
Q

What does delirium do to critical illness?

A

Complicates it

33
Q

What percentage of vented ICU pt’s get delirium?

A

60-80%

34
Q

What effect does delirium have on pt’s even after d/c?

A
  • Prolonged neurocognitive impairments
  • Poor fxnl status
  • Incr rate of LTC facility entry
  • Decr QOL
35
Q

What positions decr dyspnea & why does this work?

A

Upright & leaning forward w/arms on thighs

*Incr intra-abdominal pressure, which incr the curvature of the diaphragm, so it optimizes the diaphragm’s MA & its ability to generate pressure

36
Q

What is ICU exercise prescription based on?

A
  • Analysis of factors that contribute to impaired O2 transport
  • Hierarchy of body positions
37
Q

Implications for ICU exercise prescription

A
  • Incorporate active movement w/body changes
  • Extremes of body positioning have great benefit
  • Upright mobilization incr TV, RR, flow rates, mucocilliary transport, A/W clearance, & cough effectiveness
38
Q

How many PT’s will be needed for prone positioning of ICU pt’s?

A

Probably >1

39
Q

Protocols for exercise in the ICU

A
  • Bedside cycling improves MMT, 6MWT, & QOL
  • Incr strength=Decr vent time
  • Program should be 6wks
  • Start w/ROM progressing to positions progressing to amb
  • Do bed mobility progressed to transfers & standing
  • Do deep breathing
  • Tx the whole body
  • UBE
  • NMES
  • IMT
  • ECT
