Q

Epidural placement midline approach?

A

Skin-SQ-supra-inter-liga flavum- epidural space!

17
Q

Epidural paramedian approach

A

skin-SQ-liga flavum - epidural space!

18
Q

TAP block’s hit what?

Advantages?

Disadvantages?

A

plane between the transversus abdominis and internal oblique muscles!

intercostal nerves T7-T12 - hits iliohypogastric nerves through here

Advantages: no hemodynamic changes, no motor blockade of LE.

Disadvantages: no analgesia of visceral peritoneum or abd contents. (is an adjunct to pain management, not primary.

19
Q

IS block where?

covers what area?

A

between Anterior and middle scalene muscles
C5-C7
(spares some of C8-T1, which is why this works for shoulder, not hand.)

20
Q

What is stellate ganglion?

indications?

Complications?

A

most easily felt at C6

indications: regional circulatory insufficiency, complex regional pain syndrome.
complications: hematoma, intravascular injection, dural puncture, pleural puncture.

21
Q

Axillary block.. what is missed?

A

Musculocutaneous

22
Q

Assessment of UE blockade?

A 
4 P's
Push = radial
Pull = musculocutaneous
pinch index = median
pinch pinky = ulnar
23
Q

Bier block
How long does it last?
Tourniquet up for how long? Why?

A

Can last 45-60 minutes (use dilute lidocaine - 0.5%)

15-20 mins minimum, allows time for tissues to bind with local, limit systemic effects upon deflation.

24
Q

what nerves do wrist blocks hit?

A

radial, median, and ulnar

25
Q

if you can palpate the ulnar artery you can palpate the ?? nerve?

A

ulnar

26
Q

FNB

Remember what acronym?

A 
NAVEL:
Nerve
Artery
Vein
Empty space
Lacunar ligament
27
Q

Above knee?

A

Femoral nerve

28
Q

Below the knee

A

Sciatic

+ Saphenous (only FN present this far down) - most medial of FNB

29
Q

Largest nerve in the body?

A

Largest nerve trunk is the Sciatic nerve

30
Q

Popliteal block

A

part of Sciatic nerve
cephalad 7-10 cm (hot spot!)
Where do you put needle? NOT IN POPLITEAL FOSSA!!!! move it up 7 to 10 cm up the leg above pop crease.

31
Q

ankle block .. what are nerves?

A

deep peroneal, superficial peroneal, posterior tibial, sural, and saphenous.

32
Q

Horner’s Syndrome?

A

Blocks sympathetic stimulation to the face! * a guarentee of block of arm”

Droopy eyelid - ptosis    DROOPY!!  P = Ptosis
pupil constriction - myosis
facial anhydrosis (no sweat)
33
Q

What is the substantia gelatinosa?

A

Lamina of Rexed II (in the dorsal horn of gray matter)

34
Q

Branches of Facial Nerve? (5)

A

Mandibular, Zygomatic, Temporal, Buccal, and cervical!

To Zanzibar by motor car

35
Q

Cervical Plexus block? Where is it, why? Common problems?

A

Level of T12ish, (pt. in prone position) common for tx of abdominal visceral cancer type pains, pancreatic. Common problems are inadvertant AORTA puncture,

36
Q

CRPS Type I pain block in RUE assessed how?

A

Although Horners syndrome is common sign, this indicates SNS of the face, not necessarily the extremity itself. Look for temperature change in R limb.

37
Q

SLN? What is its function? How is it blocked?

A

The superior laryngeal nerve is comprised of two branches: the external branch which provides motor innervation to the cricothyroid muscle, and the internal branch which provides sensory innervation to the laryngeal mucosa above the level of the vocal cords. SLN block is performed between the lateral aspect of the hyoid bone and the thyroid cartilage at the thyrohyoid membrane.
