3

what percent of the population is baby boomers?

13%

4

what % of those reaching 65 will require surgery sometime before death

65

6

what are 6 chronic conditions seen with advanced age?

- Heart disease
- arthritis
- Impaired vision
- DM
-Cerebrovascular disease
-COPD

7

what are the 5 most common proedures performed in the geriatric population

- cateract extraction
- TURP
- Herniorraphy
- Cholecystectomy
- Reduction of hip Fx

8

the NIH predicts that after age 70 there is a ______% increase in mortality r/t surgery.
and ____% attributed to anesthesia alone.

300%
2% (in general population it is 0.001%) so its a pretty significant increase

9

the NIH stated what 3 things were the most frequent causes of death in pt's> 70 yo r/t surgical procedure

-MI
-Sepsis
-Thromboembolism

10

******* what is the main CV change r/t aging**** ( 1 main concept to remember)

the general response is a decreasing response to stimulation of the ANS

11

Can the old heart compensate for stress?

nope

12

What happens to the cardiac reserve in the old fart?

reduced

13

what happens to CO in the old foggie?

decreases

14

CO decreases at what rate after the age of 30?

1% (its a linear relationship)

15

CO of an 80yo is ______% of that of a 20 year old?

50%

16

What decreases at a slower rate CO or CI?

CI

17

what happens to the HR is old farts?

Decreases

18

the Maximum HR decreases about ____% per decade after the age of 50?

5%

19

what happens to conduction time in the older population?

Slowed

20

the sympathetic response in HR decreases in the elderly b/c of what?

a decreased number of sympathetic receptors

21

*** decreased CO and HR lead to what?***

Increased circulation time

22

**** Sincce the decreasd CO and HR lead to increased circulation time, what does this mean to our pt's? ****

drugs take longer to circulate

23

What happens to BP with age?

Increases

24

The mean systolic BP reaches approximately what by age 70?

150

25

**** what is important to remember with the elderly pt while in the OR in relation to BP***

Keep within 20% of baseline

26

what can happen to diastolic BP with age?

may actually fall ( decrease)

27

what happens to Systolic BP in elderly

Increase

28

**what causes the increase in systolic BP in the oldies**

-decreased distensibility of great vessels
- Arterio-atherosclerotic deterioration of vascular walls

29

What happens to the baroreceptor relfex in response to exercise and stress?

Decreasesd barorecptor reflex

30

What can develop due to a decreased barorecptor relfex in the elderly in response to stress and exercise?

postural hypotension
