25
femoral and fascia iliaca block what nerves?
femoral (reliable) saphenous (reliable) lateral femoral cutaneous (reliable) obturator (not reliable)
26
which lower leg nerve block uses less volume of anesthetic?
femoral nerve block
27
how much volume does femoral block use?
20 mL
28
FICB (fascia iliaca) is more ________
lateral
29
how much volume for FICB?
30-40 mL
30
which block is more reliable for obturator nerve?
FICB
31
which block is better at lateral femoral cutaneous nerve?
FICB
32
which block is better for hip surgery and femoral neck fractures?
FICB
33
which block is further from artery or nerve?
FICB
34
which plane is the FICB block delivered?
same fascial plane as femoral block
35
downside to femoral and FICB?
cause a motor block so only used for non-weight bearing surgeries
36
saphenous advantage
preserves motor function
37
saphenous diadvantage
only medial knee and lower leg/foot
38
other name for saphenous nerve block
adductor canal block
39
locations of needle for saphenous nerve block
groin or mid-thigh
40
adductor canal block indications
1. total knee 2. ankle/foot surgery
41
what can supplement an adductor canal block?
periarticular injection of local
42
which ankle surgery is fully covered by saphenous nerve block?
medial ankle surgery
43
which ankle surgery is not fully covered by saphenous block?
lateral ankle surgery
44
what supplements saphenous block for lateral ankle surgery?
popliteal block
45
indication for obturator nerve block
TURBT
46
does spinal anesthesia block obturator nerve reflex?
no
47
sciatic nerve block coverage: transgluteal approach
posterior thigh/knee part of hip everything below knee except medial
48
which block require sedation
transgluteal sciatic approach
49
sciatic nerve branches in popliteal fossa
tibial nerve (medial) common peroneal (lateral)
50
sciatic block coverage: popliteal
everything below knee except medial
51
most popular block for ankle surgery
popliteal block
52
how can you anesthetize the entire leg?
sciatic block with femoral or fascia iliaca
53
IPACK block
infiltration between the popliteal artery and capsule of posterior knee
54
what type of block is IPACK
sensory only
55
IPACK coverage
posterior knee
56
does the sciatic block motor
yes
57
traditional total knee blocks
femoral fascia iliaca
58
disadvantage to femoreal and fascia iliaca for total knee
