Case study 1 - Craniotomy Flashcards

1
Q

How would you assess decreased ROM of left upper limb?

A
  • Start on right unaffected limb
  • Assess cognition, proprioception, sensation.
  • Ask them to perform active
    Shoulder: extension, flexion, abduction, adduction, external + internal rotation.
    Elbow: extension and flexion.
    Wrist: extension, flexion, ulna + radial deviation, pronation + supination
  • The findings should be normal ROM
  • Compare to affected left upper limb, but do active assisted as 3/5 weakness. However, do not go past 90 degree flexion due to possible sublaxation.

Q

How would you treat decreased ROM in left upper limb?

A
  • get patient to clasp hands together and perform shoulder extension (active assisted).
  • do the same as above but elbow and wrist ROM.
  • encourage patient to reach for item at bed side etc
  • using small tennis ball, get him to place onto bed and pick up

A
  • Test both limbs, proprioception, sensation etc

Q

What evidence supports treatment of decreased left upper limb ROM?

A

KIM et all 2013
- 24 patients
- one group normal weight exercises, one group WBE
- 30 mins 3x week 6 weeks
- weight-bearing exercise can be effective in improving the ability to perform upper extremity movements and grasping power and thus can be used in stroke rehabilitation.
- weight bearing exercises shown to help increase upper limb movement and grasping strength (particuaraly extension).

Q

What evidence supports treatment of decreased strength left upper limb ROM?

A

Kim et all 2022
- Explain aims, experiment, findings and conclusions
- weight bearing exercises shown to help increase upper limb movement and grasping strength (particuaraly extension)
-with increased range of motion, from repetitive practise they can increase strngth as it is using 3/5 muscle strength.
- can progress to using small weights or body weight exercises.

Q

what is grey matter in the brain?

A
  • holds all nerve synapses
  • abundant in cerebrum and cerebellum
  • interprets sensory info. If grey horn damaged, can cause paralysis.

Q

what is white matter in the brain?

A
  • holds axons coated in myelin
  • conducts, processes and sends nerve signlas up and down spinal cord
  • if damaged can affect ability to move and react appropriately to external stimuli.

Q

isDescribe a subdural haemotoma

A
  • Hematoma = bruise caused when blood vessels under skin are damaged
    Subdural Hematoma =
    the blood seeps between the dura and the arachnoid layers, collecting in the brains tough out lining.

Q

define confusion

A

Symptoms of mild TBI · Inability to remember the cause of the injury or events that occurred immediately before or up to 24 hours after it happened.

Q

Explain contusion

A

Contusions (bruising of the brain) can be a coup or contrecoup type.

  • Contrecoup injuries classically occur when the moving head (brain) strikes a stationary object
  • coup injury is associated with a moving object impacting a stationary head.

Q

what is retrogade amnesia

A

loss of memories that were formed shortly before the injury.

18
Q

what is anteretrograde amnesia

A

loss of memory from the moment of TBI is called post-traumatic amnesia

19
Q

what is the circle of willis

A

A ring of blood vessels connecting the anterior and posterior circulations of the brain and providing important communication between them.

20
Q

Name the arteries of the brain

A
  • right + left carotid artery
  • Anterior + posterior cerebral artery
  • Middle cerebral artery
  • Anterior communicating artery
21
Q

Explain the structure of axons

A
  • nucleus
  • dendrites
  • axon terminal
  • myelin sheath
  • node of ranvier
  • synapse
22
Q

Explain how action potentials are generated

A
  • Sodium and Potassium gates open causing the resting potential to be maintained.
  • Sodium ions move in causing depolarization
  • Potassium gates open, sodium moves out
  • Potassium moves in called repolarization
  • Action potential generated
23
Q

what are spinal tracts

A

The Spinal Tracts are pathways by which motor signals are sent from the brain to lower motor neurons

24
Q

what are the ascending tracts

A

(afferent) neural pathways by which sensory info from peripheral nerves is transmitted to the cerebral cortex

25
Q

what are descending tracts

A

(efferent) the pathways by which motor signals are sent from the cerebral cortex to the spinal cord.

26
Q

what does the spinal cord attach to?

A

to the caudal aspect of the medulla oblongata of the brainstem to the level of the first lumbar vertebra.

27
Q

What spinal tracts controls muscle tone?

A

Extrapyramidal tracts (specifically reticospinal) descending spinal tract

28
Q

What is the PNS?

A

Peripheral Nervous system
- controls of the nerves that branch out from the brain and spinal cord.

29
Q

What is the CNS

A

Central Nervous System
- role in responding to dangerous or stressful situations (ie., increase heart rate)

30
Q

What are the subgroups in the peripheral nervous system?

A

Somatic - consists of nerves that go to the skin and muscles and is involved in conscious activities.

Autonomic - nerves that connect the CNS to the visceral organs such as the heart, stomach, and intestines. It mediates unconscious activities.

31
Q

What happens in synaptic transmission?

A
  • Action potential (AP) generated
  • Crosses over the synaptic gap between the presynaptic neuron and post-synaptic neuron.
  • when AP reaches pre synaptic neurone, neurotransmitters are released
  • they carry across synaptic gap
  • attach to receptor sites on post synaptic neurone
32
Q

What do the corticospinal tracts do?

A
  • descending spinal tracts
  • control voluntary, discrete, skilled motor activities
33
Q

What do the dorsal columns of spinal tract do?

A
  • ASCENDING TRACTS
  • Allow for proprioception
34
Q

what is the cerebellum?

A
  • “little brain”
  • plays a role in motor movement regulation and balance control.
  • ie., gait, balance, muscle tone
35
Q

what is intracranial pressure

A

A brain injury or another medical condition can cause growing pressure inside your skull.
- normal adult ICP is defined as 5 to 15 mm Hg

36
Q

precautions for craniotomy

A
  • Avoid bending more than 90 degrees.
37
Q

what do NICE guidelines say about craniomoty

A

Provide personalised exercises as soon as possible after a traumatic injury to maintain and improve muscle function, strength and range of movement.

38
Q

types of fractures

A
  • spiral
  • communuted

A

Stress fractures = overuse injury causing small crack in bone
Alvulsion fractures = small piece of bone attached to a tendon or ligament gets pulled away from main body of bone
Comminuted fracture = bone broken in at least two places

40
Q

complications of rib fractures

A
  • Organ damage to heart, lungs, liver, kidneys, spleen
  • Pneumothorax (collapsed lung)
  • Atelectasis
  • Pleural effusion
