Ultrasound:

what is the greatest advantage of US guided regional anesthestic

 

ability to see where the tip of the needle is in relation to anatomical structures

and see the spread of LA

 

21

Ultrasound:

can allow the provider to use less what

LA

22

Ultrasound:

can (increase or decrease) complications?

decrease

23

Ultrasound:

what freq penetrate deeper? Low or high

Low

(like a long distance runner slow and goes further)

24

 Ultrasound:

what type of freq US probes are good for visualizing shallow lying structures less than 4 cm from the skin

High

25

Ultrasound:

what is the freq of high freq US probes

 

10-13 mHz

26

Ultrasound:

what freq US prob is good for visualizig deep structures

Low

27

Ultrasound:

what is the freq of Low freq US probes

2-5 MHz

28

Ultrasound:

if sound passess through it's called ______ and appears ______ on US machine? give ex of a structure

Anechoic (no echo)

appears black

liquid (LA)

29

Ultrasound:

if sound is almost entirely reflected it's called ______ and appears ______ on US machine? give ex of a structure

Hyperechoic

bright white

Bone

30

Ultrasound:

if sound is modestly reflectly it's called ______ and appears ______ on US machine? 

Hypoechoic

gray

31

Ultrasound:

how do you differentiate an artery from a vein

 

Atreries pulsate and are NOT compressible

Veins are compressible

32

Ultrasound:

what approach affords full visualization of needle tip and shaft?

In-plane

33

Ultrasound:

what approach shows only the tip of the needle, no visualization of needle en route

out of plane

37

Label the nerve in the UE Supinated

A) median

B) Ulnar

C) Radial

D) median antebrachial cutaneous

E) Musculocutaneous

F) axillary

G) Supraclavicular

H) Intercostobrachial

38

what nerve

Median

39

what nerve

ulnar

40

what nerve

radial

41

Characteristics of movement of fingers, wrist, and elbow in response to stimulation:

What uis unique about the radial nerve

only one with extension

Causes extension of elbow

42

which nerve causes this with stimulation:

Supination of forearm

Radial

43

which nerve causes this with stimulation:

pronation of forearm

Median

44

which nerve causes this with stimulation:

flexion of wrist

 

ulnar

and

median

 

45

which nerve causes this with stimulation:

flexion of elbow

musculocutaneous

46

which nerve causes this with stimulation:

extension of wrist and fingers

radial

Again only one that causes extension

47

what type of block is a good adjunct to shoulder surgery (not interscalene)

Cervical plexus block

48

just a fact to remember.

Both cervical plexus and intercostal blocks have multiple injection sites or levels

49

what is a complication of cervical plexus block

Horner's syndrome

50

S/S of horner's sysndrome

ipsilateral ptosis

miosis

facial and arm flushing

anhydrosis

nasal congestion

51

cervical plexus block:

inject __ to __ mLs of LA per level you wish to block

3-5 mL

Remember 4 mL (C1-C4) 

Cervical plexus only consist of C1-C4
