between fascia lata and fascia iliaca

23
Q

What does the fascia iliaca block

A

Femoral, obturator, LFC

24
Q

how much volume for a fascia iliaca block

A

40 mL

25
Q

where does the LFC traverse?

A

LFC goes across sartorius

26
Q

what makes the femoral triangle

A

inguinal ligament
sartorius
medial aspect of adductor longus

27
Q

saphenous nerve block

A

distal to the adductor canal, the saphenous courses superficially in the distal thigh

28
Q

What does the saphenous nerve innervate

A

sensory aspect to medial LE below the knee

29
Q

saphenous nerve block technique

A

patient supine w/slight external rotation
transducer at distal thigh
LA deposited in fascial plane separating the adductor longus and vastus medialis below SQ

30
Q

how much do you inject for saphenous

A

5 - 10 mL LA

31
Q

sciatic block (subgluteal) anatomy

A

sciatic nerve deep to the gluteus maximus between ischial tuberosity and greater trochanter

32
Q

what does the subluteal block result in

A

sensorh + motor blockade of LE below knee EXCEPT SENSORY INNERVATION OF MEDIAL LOWER EXTREMITY

33
Q

what innervates posterior thigh

A

femorocutaneous nerve and it may be missed w/subgluteal approach

34
Q

subgluteal block

A

patient prone or lateral
low frequency curvilinear
LA deposited in fascial plane separting the adductor longus & vastus medialis

35
Q

how much LA for subgluteal bock?

A

20 mL

36
Q

what causes dorsiflexion?

A

peroneal

37
Q

what causes plantar flexion?

A

tibial

38
Q

what will you get w/ns for subgluteal block?

A

plantar flexion or dorsiflexion

39
Q

what does the popliteal nerve target

A

sciatic nerve above the knee

40
Q

popliteal fossa, the sciatic nerve is bordered

A

superiorly by semitendinosus and semimembranosus

and superior / laterally by biceps femoris

41
Q

usg technique for popliteal fossa

A

patient supine, operative leg elevated

tibial nerve is superior to popliteal artery + vein, scan cephalad to locate bifurcation w/popliteal n.

42
Q

explain the spread for popliteal

A

cicumferencial spread around the nerves

43
Q

IPACK is?

A

infiltration between the popliteal artery and posterior capsul of the knee to block the terminal branches, sparing the distal innervation of tibial and peroneal branches

44
Q

IPACK covers

A

posterior knee pain congtrol for TKA

45
Q

IPACK benefits

A

preserves foot drop, helps postop ambulation

46
Q

IPACK technique

A

lateral decub
transverse plane above popliteal crease
identify space btw popliteal artery + vein and intercondylar notch

47
Q

how much LA for iPACK

A

15 - 20 mLwhile withdrawing needle

48
Q

five nerves to foot

A 
sural
deep peroneal
superficial peroneal
posterior tibial
sapphenous
49
Q

what nerve do you always block w/foot

A

TIBIAL

50
Q

how to treat LAST

A
  1. airway management
  2. benzos for seizures
  3. treat hypotension and bradycardia

0. 25 mL/kg/m (IBW)

53
Q

max dosing of lipids

A

12 / kg
