Nursing Spinal Patients Flashcards
Why do we carry out neurological exams?
Identify if NS involvement
Identify localisation
Aid diagnosis and prognosis
Continuous assessment of condition/progression
Where can we localise neurological signs to?
Brain
Spinal cord
Peripheral nerves
Neuromuscular
What are the main parts of a neuro exam?
Hands off - mentation, gait and posture
Hands on - postural reactions, spinal reflexes, cranial nerves, sensory evaluation, palpation
Define some postural abnormalities.
Head tilt = one ear below the other
Head turn = nose turned towards body
Ventroflexion of neck = low head carriage
Scoliosis (to the side) / lordosis (curved upwards) / kyphosis (curved downwards)
Decerebrate rigidity = extension of all limbs, head and neck
Decerebellate rigidity = extension of thoracic limbs, head and neck
Wide-based stance
What postural reaction tests can we carry out?
Proprioceptive positioning
Hopping
Visual placing
Tactile placing
Hemi-walking
Wheelbarrowing
Describe lower motor neurons and their clinical signs.
Connect CNS to effector organ (muscle) and send signal to make them contract
Existing reflexes are weaker or absent
Muscle tone reduces
Muscle mass decreased rapidly and severely
Flaccid paresis/paralysis, reduced or absent reflexes, reduced or absent muscle tone, muscle atrophy
Describe upper motor neurons and their clinical signs.
Located between cerebral cortex and spinal cord, send signals to LMNs
Existing reflexes are stronger and easier to elicit
Some normally inhibited reflexes become apparent
Muscle tone increases
Loss of motor function, paresis/paralysis, normal/increased reflexes, increased extensor muscle tone, chronic muscle atrophy
What spinal reflexes can we test?
Thoracic limbs - withdrawal reflex / extensor carpi radialis reflex / biceps brachii and triceps reflex
Pelvic limbs - patella reflex / cranial tibial and gastrocnemius
Perineal reflex
Panniculus reflex
Describe the cutaneous trunci reflex test.
Tests lateral thoracic nerve, segmental nerve and spinal cord cranial to segmental nerve up to T1
Used to monitor if localisation of spinal lesion changes post-op
How can we test for deep pain sensation?
Pinching/pressure applied to digits on each limb
Look for reaction e.g. turning, vocalising, trying to bite
What cranial nerve tests can we carry out?
Menace response
Palpebral reflex
Pupillary light reflex
Gag reflex
Oculocephalic reflex
Nystagmus
Define miosis.
Constricted pupils
Define mydriasis.
Dilated pupils
Define anisocoria.
Asymmetric pupil size
How can pupil size indicate prognosis of neuro patients?
If pupil goes from miotic to mydriatic - neurologically deteriorating
Mid-size fixed pupils unresponsive to light - grave prognosis
How and why do we grade spinal cord injuries?
Grade 1-5
Allows objective assessment and monitoring of progression
Allows for more accurate prognosis
Define grade 1 spinal injury.
Pain only - no neurological deficits
Walking normally
Define grade 2 spinal injury.
Walking but with neurological deficits, causing weakness/incoordination in both pelvic limbs
Ambulatory paraparesis
Define grade 3 spinal injury.
Not able to walk without assistance but has good movement in pelvic limbs
Non-ambulatory paraparesis
Define grade 4 spinal injury.
No voluntary movement in pelvic limbs but can feel toes
Paraplegia with intact nociception (deep pain positive)
