Week 3 Geriatric patients - trauma Flashcards
what are some stats about geriatric trauma?
5 times more likley to die
1/5 falls causes serious injuries
>95% NOF caused by fall
25% of geriatric NOF die within a year
why are geriatric paitents at increased risk of trauma?
Skeletal abnormalities unsteady gait slowed reaction time cognitive imparemtns change in eyesight changes in hearing
what CNS changes impact on traumatic head injury in geriatric paitents?
Ageing brain more suceptible to shearing forces, axional injuries and heamotoma
- decreassed elasticity of bridging veins lining the meningies
- decreased number of neurons and functions
decreased brain mass and increased realtive intracranial space
how much weight does the brain shrink when we age?
10-20% by age of 80
what impact do skin changes have on trauma?
increased of full thickness injury - due to more fragile skin, less elsatin and structual support
what considerations impact on geriatric trauma in realtion to cardic changes?
> 50% hypertnesion
30% heart diseas- beta blockers or anticoagulatons- mortality 5/10% higher
increased bleeding risk if patient taking blood thinners- asprins, cloidogerl, warfin, apixaban, dabigatran, rivaroxaban

what are the intrinsic factors that can play a role in geriatric falls?
Intrinsic- age realted decline infucntion, medical conditions, psychoatric conditions, relfexes, gait
what are the extrinsic factors that can play a role in falls?
medications, unsafe footware, poorly fitted assitance devices, environmental hazzards
what is the best predicotror for a future fall?
2 or more falls in the past 12 months
What is osteoporosis?
progresive loss of bone mass
distruption of normal bone remodelling- bone reabsorbtion is greater than bone sunthesis
1/3 women over 50
