P-3 Flashcards
2/3 of medication related hospitalizations are 2/2
anticoagulants, antiplatelet and diabetes meds
Technique for reducing likelihood of adverse medication effects and improving compliance
Pruning
- use combo agents
- discard drugs not needed
- consider prognosis (<10y ?)
Pain
Nociceptive pain; usually 2/2 tissue damage
- subdivided into somatic and visceral pain
- Somatic pain: 2/2 injury to body tissues. localized
- Visceral pain: 2/2 viscera stretch receptors. poorly localized
Neuropathic/central pain:
- 2/2 a primary lesion or nervous system dysfunction
Wind-up pain:
- Slow temporal summation of pain
- mediated by C fibers.
- Repetitive noxious (<1 per 3 seconds) gradual increase
Opioids
Oxycodone 1.5 x morphine
Hydromorphone 1.5 x morphine
Typ dose ~20mg
Oral anticoagulants
Warfarin
- hepatic clearance, avoid if insufficient
Dabigatran
- Direct thrombin inhibitor
- 80% renal clearance, crcl 15-30 = 75mg bid
Rivaroxaban
- 60% renal clearance, crcl 15-50 caution
Old and drunk
Women <65
- ≤ 7 drinks/week or and ≤ 1 drink/day
Men <65
- ≤ 14 drinks/week and ≤ 2 drinks/day
65+
- ≤ 1 drink/day men and women
Postprandial syncope
due to Postprandial Hypotension
- 2/2 vagal stimulation
Also check for a fib which is common
Leading cause of vision impairment
Cataracts
- blurred vision
- increased sensitivity to glare
Leading cause of irreversible vision loss in people >65
Age related macular degeneration
- destroys the macula, impairing central vision
Nonneovascular (or dry) MC (90%)
- gradual blurring of central vision
- Tx = specific antioxidants and zinc supplements
Neovascular (or wet)
- rapid loss of central vision
- Tx = prompt referral to optho
- anti-VEGF intravitreal injections (maintain/mildly improve)
Second leading cause of blindness worldwide
Glaucoma
- typically starts in the periphery and extends inward
- MC in African americans (near vehicle accident)
Tx goal: lower IOP, slow optic nerve atrophy
Vision changes
Crystallin lens becomes less flexible with age
- less able to accommodate = presbyopia (far sighted)
Retina receives 1/3 the light of a 20 year old
- cataracts = less ability to see in dim light
Referral indications for Vision loss
Vision loss or pain or painful vision loss
- refer to optho
Joint pain
Gout = diet; podagra (big toe)
- acute = chochicine/steroids
- chronic = allopurinol/febuxostat, probenecid
Pseudogout = mechanical; Lg joints (Knee); hospitalized Px; pos birefringent
- cholchicine
Polymyalgia Rheumatica; bilateral aching, shoulder, hips, worse in AM
- steroids
Back pain
activity modification
- PT or OT
