1

________ is a greater determinant of posts complications than anesthetic management

preop co-morbid diseases

2

the most commonly occurring post op complications in the elderly are

cardiac
Pulmonary
neuro

3

thoracic, major vascular, and interperitneal sx in the elderly can increase what 3 complications

increased bleeding
Increased risk of post op vent
Increased VAP

4

aging is associated with a progressive loss of functional reserve in what organ systems

all

5

a ____% decline in organ function occurs after the age of 30

1%
(ex a 70 yo has a 40% decline in general function)

6

the elderly generally maintain homeostasis but become increasingly less able to restore it when subjected to what?

trauma
stress
disease
drugs

7

what happens to their muscle mass?

decreased

8

what happens to their Fat

increased

9

What happens to the H20 levels

decreased

10

so what happens to hydrophilic drugs

decreased Vd (less H20)

11

So what happens to lipophilic drugs

increased Vd (more fat)

12

what happens to thermoregulation

it becomes impaired
Body heat preservation is a must

13

younger pts shiver at 36.1 C, pts over 80 don't shiver until what temp

35 C

14

Shivering increasing O2 consumption by how much? and leads to hypoxia, acidosis, and CV compromise

400%

15

____ and ____ of the elderly to requires special attention b/c of fragile skin, decreased SQ fat, and poor skin turgor

positioning
padding

16

Common age related systemic anatomic and physiologic changes: what happens to
organ function

decreased

17

Common age related systemic anatomic and physiologic changes: what happens to
blood volume

decreased

18

Common age related systemic anatomic and physiologic changes: what happens to
protective reflexes

decreased

19

Common age related systemic anatomic and physiologic changes: what happens to
ability to retain heat

decreased

20

Common age related systemic anatomic and physiologic changes: what happens to
lean body mass

decreased

21

Common age related systemic anatomic and physiologic changes: what happens to
skin elasticity and collagen

decreased

22

Common age related systemic anatomic and physiologic changes: what happens to
intracellular water

decreased

23

Common age related systemic anatomic and physiologic changes: what happens to
body fat

increased

24

Common age related systemic anatomic and physiologic changes: what is a complication related to loss of protective reflexes

aspiration pneumonia

25

d/t the progressive loss of function in ALL organs what are 2 complications

increased risk for breakdown
decreased ability to repair

26

state what causes the altered CV physiology:
Increased LV wall thickness

increase in the size and Number of individual muscle fibers and adipocytes (fat cells)

27

state what causes the altered CV physiology:
Increased LV hypertrophy

chronic increases in afterload

28

state what causes the altered CV physiology:
Increased LV wall tension

chronic increases in after load

29

state what causes the altered CV physiology:
Increased afterload

decreased arterial compliance

30

state what causes the altered CV physiology:
Increased cardiac workload

reduction in arterial compliance results in increased after load, increased systolic bp, and LV hypertrophy
