finals Flashcards
geriatric patients are (more/less) susceptible to (low/high) energy mechanisms
More susceptible to serious injury from low-energy mechanisms
age range of geriatric pt
55-80
myocytes are lost and replaced by (xxx) and therefore….
myocytes are lost & replaced by collagen therefore decreased contractility & compliance for any given preload
w/o significant atherosclerotic coronary artery disease and 80 yo has this much CO of 20 yo?
50 percent
Maximal heart rate and cardiac output (increase/decrease) with age
Maximal heart rate and cardiac output decrease with age
with aging myocardium there is (increased/decreased) chronotropic response to catecholamines & dependent on preload (intravascular
volume). This leads to…
hypovolemia then shock
Deterioration of the cardiac conduction system leads to
atrial fibrillation & bundle-branch blocks
these impair the tachycardic response to catecholamines (3)
which leads to…
Digoxin, β-blockers, and calcium channel blockers
both impairing the body’s inability to compensate for hemorrhage and making heart rate an unreliable predictor of hypovolemia
Chest wall compliance, respiratory muscle strength, and the capacity for oxygen exchange all (increase/decrease) with age and response to hypoxia may decline by (x%) & to hypercarbia by (x%)
Chest wall compliance, respiratory muscle strength, and the capacity for oxygen exchange all (decrease) with age and response to hypoxia may decline by 50% & to hypercarbia by 40%
Maximum inspiratory and expiratory force may be decreased by up to (x%) compared with younger patients.
Maximum inspiratory and expiratory force may be decreased by up to 50% compared with younger patients.
can limit older patients’ ability to compensate for chest injuries
Agerelated reductions in vital capacity, functional residual capacity, and forced expiratory volume
what is first and second most common cause of injury in elderly
falls then motor vehicle crashes
most common cause of fatal and nonfatal injury in people >65
falls
what is the most common fracture of elders
hip fracture
age related changes that contributes to falls in elderly
postural stability / balance / motor strength / coordination / reaction time
what should we check for in elderly who have fallen and unable to get help for a prolonged period
promp investigation for rhabdomyolysis and
dehydration with a check of the creatinine kinase and electrolytes
this is the sum of age and body surface area burned yield the percentage likelihood of mortality
Baux Score - sum of age and body surface area burned yield the percentage likelihood of mortality
Beux score in elderly in futility of treatment and 50% risk of mortality
160 rather than 100 (futility)
110 score
at >65 yo this body surface area has anticipated mortality of 50%
bsa if 28%
inhalation burn injury adds this many points to Baux score
17 years or points
warning signs of elder abuse
untreated decubitus ulcers / injuries not explained by the reported mechanism / subacute injuries in various stages of healing
What vital signs may be blunted in elderly trauma patients?
tachycardic response to pain, hypovolemia, or anxiety may be absent or blunted in the elderly trauma patient
what may mask tachycardia in elderly
beta blockers
what may mask the signs of respiratory failure
Elderly have blunted responses to hypoxia, hypercarbia, and acidosis
must use a (higher/lower) cutoff for hypotension than in younger patients
must use a higher cutoff for hypotension than in younger patients
hypotension in elderly patients
systolic blood pressures below 110 mm Hg and heart rates above 90 beats/min
known baseline or a falling trend; a marker of instability
decrease in blood pressure of 30 mm Hg below = known baseline or a falling trend; a marker of instability
As the brain mass decreases with age this happens to bridging veins
As the brain mass decreases with age = greater stretching & tension of the bridging veins that pass from the brain to the dural sinuses
Bridging veins = more susceptible to traumatic tears.
why might diagnosis of intracranial bleeding may be delayed in elderly
brain atrophy increases intracranial free space, allowing blood to accumulate without initial signs or symptoms / blunt headtrauma patients taking warfarin who were experiencing no or minimal symptoms found w/ injury on head
what head injury imaging is recommended for elderly patients taking warfarin
Immediate noncontrast head CT = recommended for patients who take warfarin
why should INR should be checked in elderly with head injury
degree of anticoagulation correlates with the risk of adverse outcome
concern in elderly head injury patient on antiplatelet medication clopidogrel
an increased risk of intracranial bleeding after head injury
United Nation’s Disaster Management Training Program’s definition of disaster
A disaster is a serious disruption of the functioning of a society, causing widespread human, material or environmental losses that exceed the ability of the affected society to cope using only its own resources
Disaster that affects the hospital grounds

What is the hospital centered model of disaster
determined if the disaster happens on or off hospital grounds
What is advantage and disadvantage of hospital centered model
Advantage
. Ability of institution to determine if their infrastructure has been affected.
. If there is an immediate threat to the safety of the patient and employees.
Disadvantage
. It is not useful to other agencies.
. Many events are both internal and external. (Ex. Earthquake, flood or hurricane)
Acronym of man-made disasters (4)
CBRE C – Chemical ex. Release of Sarin gas by terrorists B – Biological ex. Anthrax-laced letters sent through the mail R – Radiologic / Nuclear ex. Explosion at a nuclear plant (Chernobyl) E – Explosive incidents ex. Improvised explosive device

What is PICE of disaster response
Relatively new term that has been suggested as a way of eliminating the broad term “Disaster” and using a multi-tiered system to instead focus on the needed response / May suit institutional needs / An event is described on the basis of 3 different prefixes and by a PICE stage.
