6 - Immobility Flashcards
What is the patient mortality attached to a diagnosis of “acopia”?
22%
When assessing someone’s immobility - what are the 2 questions that it is important to ask?
What is the timing of the decline in their mobility?
What is limiting their mobility?
What factors can cause immobility?
What can cause acute decline in mobility?
Infection (Sepsis)
Gout & Pseudo gout
Fractures
Soft tissue injury
Neurological - Stroke, spinal cord compression, cauda equina, vertigo
Medications
CV causes - HF, arrhythmias, acute hypoxia, anaemia
Hypoactive delirium
What can cause acute on chronic decline in mobility?
HF
COPD exacerbation
What blood tests should you do for immobility?
FBC, U&Es, LFTs, Bone Profile, TFTs, CRP
(Hypocalcaemia can cause lethargy)
How can you differentiate between gout and pseudo gout?
Gout = caused by MSU crystals deposited in joints. Crystals appeal needle shaped and are negatively birefringent. High levels of urea in blood commonly seen.
Psuedogout = caused by CPPD crystals. Crystals are rhomboid shaped and positively birefringent. High levels of urea are not really seen with this presentation.
Which WBC is commonly raised in septic arthritis?
Neutrophils
Which is the commonest joint affected by psudogout?
Knee
Then wrist
Which is the commonest joint affected by gout?
1st MTP
When considering a gout / psuedogout diagnosis - you need to rule out sceptic arthritis. How do you do this?
Aspirate the joint and send for MC&S
How are gout and psuedogout normally treated in the older population?
Use Colchicine or steroids
Dont use NSAIDs due to risk of AKI in this group
What neurological conditions can cause acute immobility in the older population?
Acute stroke
Spinal cord compression
Cauda equina
Vertigo
When should you be concerned about with vertigo?
If it is central vertigo (central vertigo often comes without warning and may last for long periods of time. The episodes are generally much more intense than peripheral, and you may be unable to stand or walk without help. Nystagmus lasts longer (weeks to months during vertigo episodes) and it does not go away when you’re asked to focus on a fixed point.
Central vertigo can be indicative of a stroke.
Peripheral vertigo is less worrying - more often indicates labrynthitis or benign paroxysmal positional vertigo.
What drugs can cause acute immobility?
Antipsychotics (from the extra pyramidal SEs = rigidity)
Sedatives
Drugs that precipitate bradycardia or postural hypotension
