Geriatric Medicine Flashcards
Acute Confusional State Predisposing Factors (5)
age > 65 years background of dementia significant injury e.g. hip fracture frailty or multimorbidity polypharmacy
Acute Confusional State Precipitating events (7)
infection: particularly urinary tract infections
metabolic: e.g. hypercalcaemia, hypoglycaemia, hyperglycaemia, dehydration
change of environment
any significant cardiovascular, respiratory, neurological or endocrine condition
severe pain
alcohol withdrawal
constipation
Acute Confusional State
Features (7)
memory disturbances (loss of short term > long term) may be very agitated or withdrawn disorientation mood change visual hallucinations disturbed sleep cycle poor attention
Acute Confusional State
Management (4)
treatment of the underlying cause
modification of the environment
haloperidol 0.5 mg as the first-line sedative- CI in parkinson’s and LBD
alternatives incl olanzapine and lorazepam
diagnosis of postural hypotension
a. A drop in systolic BP of 20mmHg or more (with or without symptoms)
b. A drop to below 90mmHg on standing even if the drop is less than 20mmHg (with or without symptoms)
c. A drop in diastolic BP of 10mmHg with symptoms (although clinically much less significant than a drop in systolic BP).
risk factors for pressure ulcers (4)
malnourishment
incontinence
lack of mobility
pain (leads to a reduction in mobility)
grading of pressure ulcers
Grade 1 Non-blanchable erythema of intact skin.
Grade 2 Partial thickness skin loss involving epidermis or dermis, or both. The
ulcer is superficial and presents clinically as an abrasion or blister
Grade 3 Full thickness skin loss involving damage to or necrosis of subcutaneous tissue that may extend down to, but not through, underlying fascia.
Grade 4 Extensive destruction, tissue necrosis, or damage to muscle, bone or
supporting structures with or without full thickness skin loss
Mx of pressure ulcers
- a moist wound environment encourages ulcer healing. Hydrocolloid dressings and hydrogels may help facilitate this.
- The decision to use systemic antibiotics should be taken on a clinical basis (e.g. Evidence of surrounding cellulitis)
- consider referral to the tissue viability nurse
- surgical debridement may be beneficial for selected wounds
Pharmacological Mx of alzheimers
mild to moderate - acetylcholinesterase inhibitor (donepezil, galantamine and rivastigmine
memantine is used when
- moderate alzheimers 2nd line
- add-on therapy in moderate to severe alzheimers’s
- monotherapy in severe alzheimer’s
Non-pharmacological Mx of Alzheimers
- activities to promote wellbeing
- group cognitive stimulation therapy
- group reminiscence therapy and cognitive rehabilitation
features of frontotemporal dementia
onset before 65
insidious onset
memory and visuospatial skills preserved
personality and social conduct problems
