18
Q

Is it appropriate for PT to treat someone who is medically induced paralysis?

A

NO

typically placed in this situation to combat severe pressure dynamics

19
Q

T/F: you can mobilize someone on a ventilator

20
Q

Contraindications/Precautions to mobility in SCI

A
  1. Spine stability
  2. Spinal shock
  3. Autonomic dysreflexia
21
Q

Contraindications/Precautions for mobilizing TBI

A
  1. Autonomic storming
    • PT typically deferred until storming subsides
    • can be consulted for bed-level positioning managment
  2. Vasospasm
    • delayed event after SAH, peak 7-9 days after bleed
    • Transcranial Doppler (TCD): measures mean blood flow velocity of arteries in neck and brain
    • >100-120 cm/s generally contraindicative for mobility
22
Q

Contraindications/Precautions for mobilizing Strokes

A
  1. tPA
    • ischemic or thrombotic CVAs
    • no OOB for 24 hrs post admin
  2. Typical hemodynamic parameters
    • ischemic event
      • permissive HTN
      • BP <220/110
    • hemorrhagic event
      • BP <150/90
23
Q

Contraindications and precautions for mobilizing seizures

A
  1. Mobility clearance → no active seizures in past 24 hours
    • may have more flexibility with small, focal seizures that are stable → check with Neuro team
  2. cEEG → ok to mobilize with MD clearance → mobility limited to in-room activities due to restrictions for EEG wires
24
Q

Contraindications and precautions for mobilizing shunt placement

A
  1. starting parameters of shunt relatively universal
    • pts will have variety of response to shunt
    • may need further adjustment by NSGY to see further improvements
  2. Ok to mobilize after surgery → monitor closely for S/S of increased ICP and/or hydrocephalus and shunt dysfunction
    • hydrocephalus signs:
      • cog signs, urinary incontinence, shuffled/magnetic gait pattern
25
Q

Contraindications and precautions for mobilizing autoimmune-related neurological events

A

(includes MG and GBS)

  1. these pts are typically managed with IVIg and plasmaheresis
    • lengthy administrations
    • pts often exhausted after treatment
    • okay to see, if tolerated, pending medical stability
      • best to try to see first thing in AM or on days off
26
Q

general contraindications for initation of PT in ICU setting (7)

A
  1. new admin of a pressor agent or antiarrhythmic agent
  2. multiple pressors being administered
  3. change in ventilator setting to provide increased ventilator support
  4. non-secured airway
  5. active GI bleed (consult with MD)
  6. elevated ICP
  7. agitation requiring increased sedative administration in the last 30 min
27
Q

normal/abnormal ICP values

A
  1. normal = 5-10 mm Hg
  2. abnormal >20 mm Hg
28
Q

methods of ICP monitoring

A
  1. Intraventricular catheter
  2. subdural bolt (ICP bolt)
  3. Implantable microtransducer sensors
  4. extraventricular drain (EVD)
29
Q

describe intraventricular catheter

what are the PT considerations?

A
  1. most accurate monitoring method (Gold Standard), but can be difficult to place when emergent
  2. catheter inserted into lateral ventricle via venticulostomy
  3. requires neurosurgery/neurology clearance for PT
  4. can be used to drain fluid out through the catheter
    • →extraventricular drain (EVD)
30
Q

describe subdural bolt

can you work with someone with a subdural bolt?

A
  1. immediate monitoring
  2. screw inserted into subdural space
  3. very easily dislodged with movement → mobility typically strictly contraindicated
31
Q

describe implantable microtransducer sensors

Can you work with someone who has these?

A
  1. intraparenchymal, epidural
  2. least invasive
  3. very expensive, generally cannot be recalibrated once in situ → can be less accurate
  4. used in situations where EVD placement is unsuccessful or when CSF drainage not necessary
  5. generally not appropriate to mobilize until removed
32
Q

describe EVDs

A
  1. uses gravity-positioned drain to clear excess CSF from brain
  2. drain will be progressively raised, decreasing rate of draining, while pt is closely monitored for adverse symptoms
    • once progressed to NSGY goal, clamp trials will start. If well tolerated, drain will be removed
33
Q

difference between clamped and unclamped EVD

what are the mobility considerations?

A
  1. when unclamped, actively draining fluid
    • pts cannot mobilize when drain is unclamped
  2. when clamped, safe to mobilize and participate in full with close monitoring
    • need NSGY clearance for clamping
    • most common adverse S/S:
      • decreased arousal, drowsiness, LOC
  3. pts should first tolerate 30 min of EVD clamped at rest prior to mobilization
34
Q

Common barriers to mobilization in the NS/STICU

A
  1. Spinal instability
  2. Autonomic storming
  3. tPA
  4. bedrest associated with endovascular intervention
  5. increased ICP
  6. vasospasm
  7. hemodynamic instability
  8. femoral sheaths (A-line)
  9. increased ventilatory support
  10. active seizures
  11. treatment interventions
    • IVIg, Plasma, Dialysis, CXT/RT, IR
35

  5. orthotics
  6. pain tolerance comorbidities
39
Q

general tips for mobilizing pts in NS/STICU

A
  1. stepwise progression of pt positioning to ensure appropriate neurological, hemodynamic, and pulmonary response to activity/upright
    • HOB elevated → chair position → EOB → bedside chair
    • EGRESS Test
      • sit to stand x3
      • marching x3
      • advancing step and return step of each foot
    • as soon as appropriate → ambualte
40
Q

ICU outcome measures

A
  1. Functional Status Score for ICU Patients
  2. Physical Function in Intensive Care Test (PFIT)
41

A
  1. 5 item performance-based measure (0-35 pts)
    • rolling, supine >sit, EOB sitting, sit >stand, walking
  2. MCD: 2.0 - 5.0 points
  3. MCID at ICU admission: 3 points
  4. Excellent inter-rater and intra-rater reliability, internal consistency
42
Q

A
  1. STS assistance, marching cadence, quadriceps strength
  2. qualitative metrics not as well studied
    • strong predictive validity comparing PFIT score on awakening and D/C home rate
