Diff types of opiods
Morphine 1st line
Hydromorphine (5x stronger than morph)- used in kidney impairment; CI in liver failure
Oxycodone (1.5x stronger than morphine) - used when neuro effects of morphine too great
Targin (slow release oxycodone + naloxone)
Fentanyl - ok w kidney impairment; least constipation; patch, not orally available
Buprenorphine - only given in chronic and stable pain
111
when to increase baseline pain relief and by how mcuh
If they have >3 breakthrough doses required in 24 hours, then increase baseline dose by 10%

120
Mx of constipation caused by opiates
Swap to Targin
or IM methyl-naltrexone
Also prescribe laxative +/- antiemetic
121
antidepressant useful in elderly patinets
mirtazepine
| SE include eating more and sleeping more which can be beneficial!
122
Problem w antipsychotics in LBD
Can worsen parkinsonisms and potentially be irreversible
Can use very low dose Seroquil/quetiapine
123
Acute and chronic stressors that can lead to depression in elderly
Acute
- grief, separation
- acute physical illness or recent diagnosis (esp stroke, PD)
- sudden change in living circumstances
Chronic
- decr health and mobility
- carer burden
- sensory loss
- cognitive decline
- social isolation
124
BIOLOGICAL mx of depression in elderly
| Obviously always have social and psychological mx to start with
SSRIs or SNRIs (be wary of SiADH), or Mirtazepine or moclobemide
+/- antipsychotics for augmentation and/or depression w psychotic features
+/- Li for augmentation
+/- Benzos, zopiclone for SX relief (insomnia, agitation)
+/- ECT for severe depression w or w/out catatonia or treatment resistance
125
Risk assessment in elderly
HTS
- Accidental (Malnutrition, dehydration (?catatonia), medication noncompliance for diabetes etc)
- Deliberate (Self harm and Suicide - need to assess RFs for suicide)
- Substance abuse
HTO - command hallucinations? past violence, involvement w police?
Protective factors (family, supports, GP, income, housing)
```
Vulnerability
◦ History of drug abuse
◦ History of physical abuse
◦ Living alone?
◦ Family support and home environment
```
Compliance to tx, medications
Absconding risk
126
Non response to treatment for psychiatric conditions - what is your approach>
Review medications - any interactions? cease or decr dose of unnecessary ones
Treat comorbidities esp HTN, DM
Reduce possible effects of handicaps caused by chronic disease, sensory impairment, poor mobility, malnutrition
Address social and psychological factors
Compliance?
Adjunct treatment and ECT
127
Pathophysiology of TBI
| what do we aim to prevent w treatment?
Primary injury
- focal injury assoc w contact (fractures, lacerations, contusions, hematoma)
- diffuse injury assoc w acceleration/deceleration injuries (diffuse axonal injuries ex from MVA)
```
Secondary injury (aim to prevent this!)
- raised ICP, local oedema, hypoxic damage, neurochemical changes
```
128
What factors determine severity and outcome of TBI?
GCS (mlid if >= 13; severe if <=8)
Duration of LOC (mild if <30min; severe if >24h)
Post traumatic amnesia (mild if <1 day; severe if >1week)
129
Complications of TBI
Neurological
- visual changes (diplopia, CN 6 palsy, blurred vision, hemianopia and VF loss)
- loss of taste and smell
- vertigo, dizziness
- dysphagia, dysarthria
- weakness
- sensory impairment
- apraxia
- neglect
Medical
- spasticity
- epilepsy
- hydrocephalus
- endocrine - siADH, DI
- psych (depression, PTSD)
Cognitive
- dysexecutive syndrome from frontal lobe damage
- memory deficits (PTA)
- attention and focus (PTA)
- Slowed processing
- cognitive and physical fatigue
130
Management of spasticity
PT
+/- serial casting and splinting
+/- meds (PO baclofen, botulinum toxin injections)
131
Features of PTA
```
Memory impairment following TBI
Disorientation
Poor attention
disrupted sleep-wake cycle
fatigue
irritability, aggression
Overstimulation
```
Essentially the same as delirium except for context
132
Rehabilitation post TBI
Monitor and manage any PTA
- assess cognition/function after emergence and rehab
Prevent and treat complications of TBI
PT and OT to optimise mobility and function
Education for PT and carers
Follow up +/- OP rehab
Long term: OT driving assessment and return to work (SW)
133
Mx of sports related concussion
Rule out structural damage w CT and confirm diagnosis
Neuropsuch (SCAT) to estimate recovery and return to play (graded return)
134
What is post concussion syndrome?
Small group of patients develop persistent Sx (>3mo duration) following a minor TBI
GP to monitor for this
SX include
1. physical (fatigue, headaches, blurred vision, dizziness)
2. cognitive (concentration, attention, memory)
3. behavioural (irritation, depression, poor socialisation)
135
Complications following stroke
Secondary stroke/TIA/haemmhoragic transformation so need secondary prevention ASAP
```
Spasticity
Pain
Depression, cognition
Falls
Bladder/bowel incontinence or constipation
UTIs
Sexual dysfunction
Sleep apnoea (central)
Fatigue
Malnutrition and dehydration
Complications of immobility (pressure wounds, pneumonia, orthostatic hypotension, dependent oedema, reconditioning, DVT/PE, contractors, osteoporosis)
```
136
Stroke prognosis
1/3 die
1/3 recover completely
1/3 persistent impairment
137
Components of inpatient rehab for stroke
Prevent and manage complications - nutrition and swallowing; contractures, spasticity, bladder, depression etc
Incr independence in PADLs - compensatory techniques +/- equipment
Incr independence in mobility - gait aids, gait/transfer retraining
Communication, cognition, behaviour -assess for deficits, educate and manage
Home assessment,
Home services application
Education and support counselling for pts and family (fam meetings, driving, return to work, sexual and interpersonal, carer education)
DC planning
138
Rehab interventions for weakness
Limb positioning, Splinting, Passive ROM exercises, resistance exercises to AVOID CONTRACTURS
Practice functional tasks
Compensatory tasks (PT, OT)
Spasticity MX (stretching, positioning, splinting, baclofen, bot toxin injections etc)
139
When should you expect most recovery to occur in rehab post-stroke?
Most rapid recovery in first 3 months post-stroke
| Completes around 6 months
140
Indicators of poor prognosis post stroke
```
Large stroke size
Old age
MAny comorbidities
Stroke mechanism and location
Dense clinical findings
Complications
Functional status prior to stroke
Poor family and social support
Poor motivation and cognitive impairment
